magnetised particles on magnetic disks, small charges of electricity, and rapid pulses of light, so it is very easy for some of the data to change unintentionally, perhaps because of electrical interference or imperfections in the way a device has been made. +Error control is a clever idea that enables computers to put data back to how it was before it was messed up, usually without the

Most of the time this 'agent' means a computer or other type of digital device - but it could also be a human! We’ll refer to it as a computer to make things a bit simpler. To represent solutions in a way that a computer can carry them out, we have to represent them as a step by step process - an algorithm.

Throughout the lessons and units in CS Unplugged there are many links to Computational Thinking. Teaching Computational Thinking through CS Unplugged activities teaches students how to:

  • describe a problem,
  • identify the important details needed to solve this problem,
  • break the problem down into small, logical steps,
  • use these steps to create a process (algorithm) that solves the problem,
  • and then evaluate this process.

An algorithm is a step-by-step process that solves a problem or completes a task. If you follow the algorithm's steps correctly, you will arrive at a correct solution, even for different inputs. For example, we can use an algorithm to find the shortest route between two locations on a map; the same algorithm can be used for any pair of starting and finishing points, so the solution depends on the input to the algorithm. If we know the algorithm for solving a problem then we can solve that problem easily, whenever we want, without having to think! We can just follow the steps. Computers can’t think for themselves, so they need to be given algorithms to do things." -msgstr "crwdns15688:0crwdne15688:0" - -msgid "Algorithmic thinking is the process of creating algorithms.

The important aspects can be used to create a model, or simplified representation, of the original thing we were dealing with.

Computer Scientists often work with multiple levels of abstraction." -msgstr "crwdns15692:0crwdne15692:0" - -msgid "We use abstraction often in our everyday lives, for example when we use maps.

For example, let's say you took a nice scenic photo on your last camping trip, and now you want to edit it on your laptop and adjust the colours in it.

On the surface it seems like a fairly simple interface: a text box where you type what you want to search for, and a button to start the search. The level of programming knowledge needed to implement a text box and a button is fairly rudimentary, and you could implement a search by writing a short program (probably less than 20 lines) to go through all the text on the web and displaying any that match.

We need to keep it secure - users don't want other people to know what they are searching for, and the search engine doesn't want commercial interests to manipulate search ranking (Computer Security and Encryption)? Search engines generally predict what you are about to search for (Artificial Intelligence). It needs to be reliable - a small mistake from one of the thousands of programmers at a search engine company shouldn't prevent the site working (Software Engineering). It needs to scale well - if it becomes 10 times as popular, you don't want it to need 100 times the computing resources (Algorithms).

+            These activities are based on live sessions using video conference systems such as Zoom, Google Meet, or Microsoft Teams.
+            Below is a step-by-step guide for preparing to deliver CS Unplugged at a distance sessions.
+        

+
+        

+            These activities are based on live sessions using video conference systems such as Zoom, Google Meet, or Microsoft Teams.
+        

+
+        

+            Disclaimer:
+            The software, applications and equipment listed in this section and in the lessons are all tools that we used in 2021 - 2022 while developing these resources.
+        

+
+        
Key principles

+
+        
We followed several principles when designing lessons for online only situations:

+
+        
Appropriate for all

+
+        
The activities on CS Unplugged at a distance content have been taught at all age levels.

+
+        
Easy to deliver

+
+        
Our content has everything you need within the online slide deck. Each lesson has one key computer science concept for you to focus on.

+
+        
Considerate of people’s time

+
+        
These presentations are concise and easy for facilitators, as well as making the best use of the participants’ time.

+
+        
Planning a session

+
+        
This section supports you to plan and prepare for delivering a session.

+
+        
General presentation considerations

+
+        
    
+            
  • Have separate notes and/or print the speaker notes. This allows you to focus on facilitating and following the suggested script and facilitation notes while avoiding the audience seeing them.
    • 
+            
  • Opening a presentation room 15 minutes before the start time allows participants to make sure they are logged in with time to resolve any technical issues before the presentation begins.
    • 
+            
  • Mute participants' microphones unless they are speaking.
    • 
+        

+
+        

+            Looking for ways to maintain the CS Unplugged feel
+            

+                

+                    The lessons include interactives, so you don’t need to use any props.
+                    You may want to incorporate physical CS Unplugged material into your presentation to demonstrate how it works face-to-face.
+                

+
+                
Here’s some ways you might do that:

+
+                
    
+                    
  • 
+                        If you are using a whiteboard, have a whiteboard behind you (or a small hand-held whiteboard).
+                        Consider where you are positioned and how easy it is to transition between teaching at the whiteboard and your screen.
+                    
    • 
+                    
  • 
+                        If you are holding up an object to the camera, remember that a blurred background setting may mean that your audience can’t see the object unless it’s in front of you.
+                    
    • 
+                    
  • 
+                        If you have a document camera directly connected as your main camera (rather than via screen sharing), make sure special effects like blurring backgrounds or ‘touching up appearance’ are switched off.
+

+            

+        

+
+        
Which online platform will you use?

+
+        

+            Some organisations and schools only allow one platform such as Zoom, Microsoft Teams, or Google Meet to be used, and some will block access to other platforms.
+            Make sure that you have mentioned what platform you are using in your promotional material.
+        

+
+        
Familiarising yourself with the platform's settings and features

+
+        

+            We recommend using the following security settings to ensure your presentation is not accidentally interrupted:
+        

+
+        

+            Note: Some of these settings may not be available until the meeting is running.
+        

+
+        
    
+            
  • Removing the participants ability to share their screen.
    • 
+            
  • You may want to consider allowing or disabling the ability for participants to unmute themselves or show their video.
    • 
+        

+
+        

+            We highly recommend familiarising yourself with how to mute or unmute a participant if needed.
+            Online platforms tend to switch the screen to show whoever is speaking (including background noises) which can interrupt the flow of your session.
+        

+
+        
How will your participants interact with this session?

+
+        

+            Encouraging participation is key to making online sessions engaging.
+            Most platforms offer a variety of options for interacting with participants, but we have found the most immediate and reliable system is the standard text chat.
+            Participants can get a strong sense of the group's responses as they see them go past in the chat window.
+            Our lessons have been designed to only use this feature.
+            If it is a smaller group (fewer than 10) allowing participants to speak can also work.
+        

+
+        

+            Other interaction features
+            

+                

+                    Some of the Unplugged activities would seem to work well with polls and audience responses systems, but these can take some time to set up, and you often have to wait until everyone has responded, which can interrupt the flow of the session.
+                

+
+                

+                    Consider the financial cost (to you and your participants) and immediacy of responses with different software.
+                    Sometimes “trial” versions of software have limitations that can interrupt the flow of the event.
+                    Also, using features built into the video conference system (such as text chat) avoids asking participants to install more software.
+                

+
+                

+                    Often the previous messages in the chat aren't available to people who join late; for example, if you post a link to a web page that they should be looking at, late arrivees may not be able to see the link.
+                    You may need to repeat messages for new arrivals.
+                

+            

+        

+
+        
Are you recording this session?

+
+        

+            Sometimes people will ask you to record a session.
+            This raises privacy risks, and can inhibit questions and conversations.
+            If someone can’t be there live, it may be better to offer an alternative repeat session, or post a summary in a different format that’s more suitable for them to read or view.
+        

+
+        
If you are using breakout rooms recording becomes problematic as you can’t usually record the conversations in the breakout rooms.

+
+        
Running a session

+
+        
Running an online session (especially the first time) can be stressful but we have provided some tips below to make it as smooth as possible.

+
+        
How are your participants accessing this session

+
+        
Consider the different ways people may be viewing the session, such as individually or in groups, and how this might affect the way you interact with your participants.

+
+        

+            Hearing feedback?
+            

+                

+                    Have each participant mute their microphone unless they’re speaking.
+                    If feedback is still occurring, make sure the speaker’s speaker is not too loud.
+                

+            

+        

+
+        

+            Participants watching in groups?
+            

+                

+                    Encourage each participant to sign in on their own device so they can use the chat feature individually.
+                    They will need to have their microphone and speaker muted so they don’t hear the audio multiple times.
+                

+            

+        

+
+        
Familiarising your participants with the online platform

+
+        

+            It’s good to ask some ice-breaker questions while people are joining your session.
+            You could ask for responses in the chat to questions like “Where are you/your group joining us from?” or “What age group do you teach?”.
+            This is a great opportunity for participants to get familiar with the chat functionality.
+        

+
+        
Engaging your audience

+
+        

+            Using the chat functionality is an effective way to engage participants.
+            As a facilitator, be mindful that it does take time for your participants to think of an answer, type it, and for it to appear in the chat.
+            The response time depends on the question, and it could take up to 20 seconds before answers start to appear.
+            It’s important to not speak during that time to allow people to think.
+        

+
+        
If it’s a small group, open the discussion by allowing your participants to unmute their mics and ask them to indicate they have something to add by raising their hand.

+
+        

+            Other features
+            

+                

+                    Breakout rooms can sometimes be useful during large online workshop presentations, but we have written these resources to keep the participants together.
+                    Using breakout rooms can require some experience to be effective, and can depend on having people available to facilitate them if you have a lot of participants.
+                    The time it takes to organise people into breakout rooms can interrupt the flow of a session, but if you’re confident using them, they can be used with discretion to manage activities.
+                

+            

+        

+
+        
Participant privacy

+
+        
Supporting the privacy of participants is important, especially if you’re recording the session. Here are some general tips:

+
+        
    
+            
  • 
+                Remind participants at the beginning of each session that others can see their background.
+                Allow them to turn their cameras off if they like.
+            
    • 
+            
  • 
+                Remind participants at the beginning of each session that they can change their name that appears on their screen for others to see.
+            
    • 
+            
  • 
+                Familiarise yourself with how to mute individual participants in case they unmute themselves and unwanted sound is heard.
+            
    • 
+        

+
+        
If things go wrong

+
+        

+            Firstly, don’t stress, things go wrong, we are all human.
+            Here are some ways you can prepare yourself for the unexpected.
+        

+
+        
    
+            
  • 
+                Remember the mute functionality is great for stopping disruptions.
+            
    • 
+            
  • 
+                Check what the host connection rights are in the online platform if the host drops out.
+                Will the session automatically end?
+            
    • 
+            
  • 
+                Have a way to communicate with participants if the live session is terminated unexpectedly (e.g. have their email addresses at hand so you can quickly send information about what you will do).
+            
    • 
+            
  • 
+                Have a mobile device fully charged, with internet connectivity, ready to log into the online platform in case your primary device fails.
+            
    • 
+        

+
+        
And remember to have fun!

+

+                    CS Unplugged at a distance is a series of short lessons adapted from CS Unplugged activities that are suitable for teaching online to students, or for training educators.
+                

+                

+                    CS Unplugged is always better in person!
+                    But if you find yourself having to facilitate online, this content is adapted to support this.

-# Binärzahlen
-
 Computer verwenden heutzutage Binärzahlen um Daten darzustellen – deshalb werden sie auch digitale Systeme genannt. Die einfachste und gebräuchlichste Art und Weise, Zahlen darzustellen, ist das binäre Zahlensystem, das aus nur zwei Ziffern besteht (normalerweise als 0 und 1 geschrieben). Es wird binär genannt, da es nur zwei verschiedene Ziffern bzw. Zustände gibt.

-# Binary numbers
-
 Computers today use digits to represent information - that's why they're called digital systems.
 The simplest and most common way to represent digits is the binary number system, with just two digits (usually written as 0 and 1).
 It is called binary because there are only two different digits used, or two states.

+In fact, if you have learnt about check digits in the [Error Detection and Correction unit]('topics:topic' 'error-detection-and-correction'), then you have already used a simple hash function - the formula we use to calculate a check digit is a hash function.
 When we use hash tables for searching we use hash functions to locate data, and in these other areas it is used to validate data and check it is correct.
 Some of the hash functions used in this unit, for specific sized hash tables, follow a pattern.
 This pattern can be used to make an algorithm that means we can apply these hash functions to hash tables of any size.

 As with a sorting network, at each node a comparison is made between two numbers, and the result of this comparison tells you where to go next.
 The interesting thing to observe here is that using just one very simple comparison operation (in different ways), we are able to both sort data into order, and search through it.
 Another connection between these two activities is the type of data that can be used - the data must have something called a "transitive relation".
-This is further explained under logic, and also in the [Sorting networks unit plan]('topics:unit_plan' 'sorting-networks' 'unit-plan') under logic.
+This is further explained under logic, and also in the [Sorting networks topic]('topics:topic' 'sorting-networks') under logic.
 Because it is based on a simple comparison step, any type of data that can be sorted using a sorting network can also be placed into a binary search tree.
 As binary search trees are abstract data structures, they can be generalised for use with any type of data that can be put into some kind of order.
 The other connection students will likely make is between binary search trees, and binary search! While the names are almost the same, the actual pattern they both follow is subtly different, although they both make use of the divide and conquer strategy.

+# Le tour de magie du retournement rapide de carte
+
+{image file-path="img/topics/kids-parity-trick.jpg" alt="Enfants utilisant l'astuce de la parité."}
+
+*Chaque donnée que nous stockons et transmettons possède des bits supplémentaires afin d'éviter les erreurs. Pouvez vous trouver l'erreur et la corriger ?*
+
+### Équipement :
+
+Au moins 36, voire 100 cartes ou plus qui sont noires d'un côté, et blanches de l'autre, d'environ 20mm par 20mm (ou n'importe quelle paire de couleurs facilement distinguables) Un espace libre au sol ou une table autour desquels les élèves peuvent se tenir
+
+### Préparation :
+
+Choisissez un "maitre magicien". Ce sera le maitre du jeu. Cette personne sera changée à la fin de chaque tour.
+
+### Instructions :
+
+1. Le maitre magicien pose les cartes au sol, dont les cartes de parité dans la dernière ligne et la dernière colonne, en utilisant un membre du groupe comme assistant. La grille peut être de n'importe quelle taille ; au minimum 6 par 6, mais la taille peut aller jusqu'à 10 par 10 ou plus pour rendre le défi plus compliqué. La grille ne doit pas nécessairement être carrée (par exemple 9 par 8 fonctionne), mais l'effet est meilleur quand la grille est proche d'un carré.
+
+2. Le maitre magicien demande à tout le monde de fermer les yeux et de se retourner, sauf lui et son assistant.
+
+3. Le magicien demande à l'assistant de choisir une carte, place un compteur ou une marque sous l'emplacement de la carte et la retourne.
+
+4. Une fois cela fait, le maitre magicien clame (calmement)... "que la magie commence" et démarre le chronomètre. Quand les autres élèves entendent cela, ils se tournent et tentent de trouver "l'erreur".
+
+5. Aussitôt qu'ils trouvent l'erreur, ils mettent leur doigt sur leur nez.
+
+6. Le magicien arrête le chronomètre et demande à la première personne qui à mis le doigt sur son nez de montrer où se trouve la carte qui a été retournée.
+
+7. L'élève pointe la carte retournée, vérifie si c'est bien la bonne en la retournant.
+
+8. S'il a raison, il explique comment il a trouvé la qui carte a été retournée.
+
+9. Le maitre magicien enregistre le nom de l'élève qui a gagné ce tour et son temps.
+
+10. A-t-il battu le temps précédent ?
+
+11. S'il a amélioré le temps précédent, il devient l'assistant. L'élève qui gagne ce tour reste l'assistant tant que son temps n'est pas battu.

-# Couleur par les nombres
-
-## Questions clé
-
-- Comment pensez-vous que les ordinateurs affichent des images sur un écran?
-- Comment les ordinateurs stockent-ils des images s'ils ne peuvent mémoriser que des informations sous forme de chiffres ?
-
-## Lancement du cours
-
-Ce cours contient 2 activités : une que les élèves peuvent faire seuls et une activité de groupe. Pour chaque activité, vous aurez besoin de suffisamment de feuilles pour que chaque élève en ait une. Chaque activité nécessite différentes versions des feuilles du Peintre Pixel. Utilisez les couleurs **Noir et Blanc** (la première option de la liste), et :
-
-- Pour la première activité choisissez les images de la page 1 (l'étoile, la tasse de thé, ou le chat). Vous pouvez utiliser une combinaison de ces images, les élèves n'ont pas besoin de tous faire la même,
-- Pour la seconde activité, choisissez parmi les images des pages 6, 8 et 9. Imprimez suffisamment d'exemplaires pour que chaque groupe d'élèves possède l'ensemble des images.
-
-{panel type="general"}
-
-# Notes sur les ressources
-
-- Imprimez des copies de chaque feuille de travail au cas où les élèves se trompent et aient besoin d'une nouvelle feuille.
-- Utilisez les choix de couleur **Noir et Blanc (2 valeur binaires possibles)**, et **pas** l'option qui dit "en codage par plages".
-- Les élèves peuvent utiliser des pastels noirs, un crayon, ou un feutre, mais des crayons effaçables fonctionnent bien mieux la première fois que les élèves font l'activité.
-
-{panel end}
-
-Le professeur à la classe : Les écrans des ordinateurs sont découpés en une grille de petits carrés, chacun pouvant afficher une couleur. On appelle ces carrés "Picture elements", ou pixels.
-
-Écrivez les mots "Picture elements" au tableau. Pour montrer comment nous obtenons le mot pixel, entourez le "pi" de picture et le "el" de elements, et écrivez "pixel" en dessous.
-
-L'enseignant à la classe : Chacun de ces pixels peut être d'une couleur différente, et quand il y en a beaucoup sur un écran, ils forment une image. Quelqu'un a déjà entendu parler de pixels ? Et de megapixels ?
-
-{panel type="general"}
-
-# Observations pour l'enseignant
-
-Megapixel signifie un million de pixels. Les élèves peuvent avoir entendu le terme "megapixel" précédemment car les appareils photos sont souvent décrits par une quantité de megapixels, par exemple un téléphone peut avoir un appareil photo de *12 megapixels*. Cela décrit la résolution des photos que la caméra peut prendre. Une caméra de 12 megapixels peut produire une image contenant 12 millions de pixels.
-
-Les écrans de télé et les projecteurs affichent aussi des images en utilisant des pixels.
-
-{panel end}
-
-L'enseignant à la classe : Chacune des images que l'on voit sur un écran, que ce soit une photo, une vidéo, ou du texte, est affichée en utilisant des pixels, et tout ce qu'un ordinateur a besoin de stocker est la couleur que doit avoir chaque pixel de l'écran.
-
-Montrez les images suivantes aux étudiants sur un écran ou au tableau.
-
-L'enseignant à la classe : Dans une image en noir et blanc, chaque pixel peut être soit noir soit blanc, donc la seule chose que les ordinateurs ont besoin de stocker est quels sont les pixels noirs et quels sont les pixels blancs. Par exemple, si nous voulons afficher la lettre **C**, nous devons commencer par diviser la lettre en carrés. Si on zoome encore plus, on peut observer une grille de pixels similaire à ça :
-
-{image file-path="img/topics/letter-zooming-to-pixels.png" alt="Trois images de la lettre majuscule 'C' sont montrées. Elles zooment progressivement pour montrer les carrés noir et blancs qui forment la lettre à l'écran."}
-
-Nous pouvons représenter cette image en utilisant des chiffres binaires (bits). Si un 1 indique un carré blanc et un 0 un carré noir, alors on peut représenter notre lettre **C**, sur une grille de 5x6 pixels, comme cela :
-
-**10001, 01110, 01111, 01111, 01110, 10001**
-
-Si nous prenons ces nombres et dessinons l'image qu'ils représentent, nous obtenons la lettre **C** :
-
-{image file-path="img/topics/pixel-visible-grid-with-letter-and-numbers.png" alt="Une grille 6x5 est affichée. Certains des carrés sont blancs, d'autres sont noirs, ce qui permet de créer la forme de la lettre 'C'. À la droite de chaque ligne de carrés, il y a 5 chiffres binaires qui décrivent l'image."}
-
-Nous utilisons 1 pour représenter blanc et 0 pour représenter noir, de la même manière que nous avons utilisé les cartes noires et blanches pour représenter 'on' et 'off' dans le module des nombres binaires.
-
-## Activités de la leçon
-
-Donnez la première feuille de travail aux élèves et demandez leur de regarder la grille de carrés. Que remarquent-ils à propos des nombres dans les carrés ? Il sont tous soit 1 soit 0.
-
-L'enseignant à la classe : Les grilles sur ces feuilles représentent les pixels sur un écran d'ordinateur. Maintenant vous allez être l'ordinateur et utiliser les nombres dans les carrés pour faire une image.
-
-Sur les feuilles, demandez aux élèves de colorer chaque carré avec un 0 en noir, et laissez les carrés avec un 1 en blanc. Nous utilisons 1 pour représenter blanc et 0 pour représenter noir, car 1 indique qu'un pixel est 'allumé' (et donc blanc) alors que 0 indique qu'il est 'éteint' (et donc il est noir). En coloriant les carrés 0 durant cette activité, les élèves 'éteignent' ces pixels. Conseillez-leur de colorier légèrement les carrés au début, puis lorsqu'ils sont certains qu'ils n'ont pas fait d'erreur ils peuvent les colorier complètement. Alors qu'ils travaillent sur les feuilles ils devraient voir une image apparaître.
-
-L'enseignant à la classe : Maintenant que nous avons fait des images simples avec nos nombres et nos pixels, nous pouvons essayer d'en faire des plus détaillées et plus dures. Comment pensez-vous que nous pourrions faire des images plus détaillées ?
-
-{panel type="general"}
-
-# Observations pour l'enseignant
-
-Les réponses possibles incluent d'ajouter plus de couleurs. C'est une bonne réponse et les couleurs seront dans des leçons plus avancées de ce cours, mais cette leçon se concentre seulement sur les pixels en noir et blanc, rappelez donc aux élèves cette contrainte et demandez leur comment faire une image plus détaillée en noir et blanc.
-
-Ils peuvent aussi suggérer d'utiliser des pixels plus petits pour la même image. C'est une bonne réponse et cela pourrait être une idée à explorer par les élèves dans un futur cours. Pour le moment, nous cherchons à créer des images plus compliquées et plus détaillées, plutôt que de rendre les précédentes plus détaillées.
-
-{panel end}
-
-La réponse que vous attendez est d'utiliser plus de pixels pour l'image, c'est ce que les élèves vont faire dans la prochaine activité.
-
-Mettez les élèves en groupes et donnez à chaque groupe l'ensemble des images sur plusieurs pages, de sorte que chaque élève ait une page sur laquelle travailler. Si ce n'est pas possible avec le nombre d'élèves que vous avez, assurez-vous que les groupes soient suffisamment petits pour que chaque élève ait au moins une page, ou, de préférence, que chaque élève ait le même nombre de pages. Par exemple, faites travailler les groupes de 3 sur 6 pages, de sorte que chaque élève ait 2 pages à remplir.
-
-L'enseignant à la classe : Ces ensembles de grilles peuvent être combinés pour créer une image plus grande, qui contient bien plus de pixels que les précédentes. Vous allez tous colorier les pixels sur votre propre feuille, comme précédemment, puis assembler l'image complète.
-
-Une fois que les élèves ont colorié leur feuille, il peuvent les assembler pour former l'image complète. Il y a des indications sur les imprimables que les enseignants peuvent utiliser pour aider les élèves à assembler leurs images s'ils sont coincés.
-
-## Appliquer ce que nous venons d'apprendre
-
-- Les élèves peuvent utiliser une grille ou un papier quadrillé pour créer leurs propres images. Demandez aux élèves d'écrire les chiffres binaires qui représentent leur image (de la même façon que le 'C' dans la section de démarrage du cours, au lieu d'écrire les 1 et les 0 dans chacune des cases de la grille), donnez ceci à d'autres élèves, et voyez s'ils peuvent recréer la même image.
-
-- Il y a un certain nombre de sites disponibles que les élèves peuvent utiliser pour créer facilement du pixel art. Ils peuvent créer leur propre pixel art, convertir cela en une grille de chiffres, et ensuite faire en sorte que leurs amis essaient de recréer leur image.
-
-- Maintenant que les élèves ont essayé de créer des images plus grandes, ils pourraient aller plus loin et faire une image en tant que classe entière. L'option Perroquet du Peintre Pixels est composée de 32 pages, et constitue un grand défi pour une classe.
-
-{panel type="general"}
-
-# Notes sur les ressources
-
-Il y a une [grille]('resources:resource' 'grid') de 8 par 8 dans la section des imprimables qui peut être utilisée pour dessiner ces images.
-
-{panel end}
-
-## Réflexion sur la leçon
-
-Cette leçon portait sur les images en noir et blanc; pourquoi ne pouvons-nous pas faire plus de deux couleurs avec cette activité ?
-
-- Avec un chiffre binaire, nous ne pouvons représenter que deux valeurs différentes. Cela signifie que si nous utilisons un chiffre pour représenter la couleur d'un pixel, chaque pixel ne peut être qu'une de deux couleurs différentes.
-
-Que pourrions-nous faire pour représenter plus de couleurs ?
-
-- Si nous voulons que chaque pixel soit capable de montrer plus de couleurs que le noir et le blanc, alors nous devons utiliser plus de nombres (i.e., plus de chiffres binaires) pour représenter la couleur de chaque pixel. Cela sera exploré lors des prochaines leçons.

+
+## Exemple de fil conducteur
+
+Les résultats de la compétition de la meilleure vache du pays sont arrivés et les 31 meilleures sont listées par ordre de poids de la plus lourde à la plus légère. Ces vaches ont été ramenées dans leurs fermes à travers le pays.
+
+Personne ne savait que dans les collines était caché un géant très affamé, qui adorait le bœuf rôti par dessus tout et avait tendance à rôtir une vache entière à la fois. Ce géant avait une mémoire fantastique et avait appris par cœur non seulement l'ordre des vaches, de la plus lourde à la plus légère, mais aussi dans quelle ferme elles se trouvaient et où les fermes étaient. Le géant commence à la ferme avec vache la plus lourde et continue petit à petit dans l'ordre décroissant des poids.

+Un assassin de géant est appelé pour trouver le géant affamé. L'assassin de géant sait que le géant est passé par une ferme si la vache a disparu. Si la vache est toujours dans la ferme, le géant doit être dans une ferme avec une vache plus lourde, mais si la vache n'est plus là, le géant doit être dans une ferme avec une vache plus légère.
+
+## Votre tâche
+
+Réaliser une animation image par image ou une pièce de théâtre qui montre que le géant utilise une recherche séquentielle pour manger les vaches par ordre de poids décroissant, et que l'assassin du géant qui doit empêcher le géant de manger toutes les vaches peut facilement trouver le géant avec une recherche dichotomique avant que le géant n'ait mangé trop de vaches.
+
+### Supplément pour les experts
+
+Vous pouvez changer le cadre et les personnages mais conserver le thème de l'histoire !
+
+Gardez en tête qu'un algorithme de recherche suit toujours les mêmes règles pour trouver une solution.

+# Réseaux de Tri
+
+En tant que consommateurs, nous nous attendons à ce que les ordinateurs traitent les informations aussi rapidement que possible, de sorte que les programmes s'exécutent plus rapidement, que les sites web se chargent plus vite, et pour que nous n'ayons pas à rester longtemps devant une barre de progression ou une roue qui tourne, indiquant qu'un ordinateur est en train de réfléchir ! Une façon d'augmenter la vitesse d'un ordinateur est d'écrire des programmes qui utilisent de moins en moins d'étapes de calcul (comme indiqué dans les leçons sur le tri et les algorithmes de recherche). Une autre façon de résoudre les problèmes plus rapidement est d'avoir plusieurs ordinateurs qui travaillent sur différentes parties de la même tâche en même temps. C'est ce qui est abordé dans cette leçon.

-Dev Application
-##############################################################################
-
-This application:
-
-1. Provides a quick reference for viewing what content has been added to the database.
-2. Allows authors to check Markdown content has rendered as expected.
-3. Is only to be used in a development environment.
-
-This application is available only when ``DEBUG`` mode is enabled (and therefore is not
-visible in production). ``DEBUG`` mode is enabled by default when developing locally.
-
-This application does not necessarily show the same connection/layout of content as in
-the actual site itself. This is because some of the links in this app link to the actual
-site, but many link to a copy of the template from the topics app (and are therefore are
-likely to be out of date at any given point in time).
-
-
-What does this app contain?
-==============================================================================
-
-The dev application currently contains the following:
-
-- Topics - a list of available topics, and links to the corresponding template in the
-  topics applications. The children listed under each topic are:
-
-    - Unit Plans and Lessons. - All of these link to the corresponding page in the Topics
-      application. The purpose of this list is to give an overview of which lessons have
-      been added to each unit plan, and which unit plans have been added to each topic.
-      It is possible for someone to have created a markdown file for a lesson (or unit
-      plan, or topic) but it not be shown in this list, this is because only Markdown
-      files listed in configuration (``yaml``) files are loaded into the database.
-
-    - Curriculum Integrations - a list of curriculum integration activities. This **does
-      not** link to the template from the topic application. This is because a curriculum
-      integration only has to be linked to a topic (at the very least) in order for it to
-      be loaded into the database, i.e. it is possible for a curriculum integration to be
-      loaded into the database without it being assigned to a lesson.
-
-    - Programming Challenges - a list of programming challenges. This **does not** link to
-      the template from the topic application. This is because a programming challenge
-      only has to be linked to a topic (at the very least) in order for it to be loaded
-      into the database, i.e. it is possible for a programming challenge to be loaded
-      into the database without it being assigned to a lesson.
-
-- Curriculum Areas - a list of curriculum areas and their subdomains.
-
-- Learning Outcomes - a list of learning outcomes.
-
-- Programming Challenge Languages - a list of programming languages that programming
-  challenge solutions can be given in.
-
-- Programming Challenge Difficulties - a list of difficulty levels and their corresponding
-  title.

+
+00:00:06.840 --> 00:00:09.620
+Cool, donc la dernière leçon que nous avons faite nous avons regardé
+
+00:00:09.620 --> 00:00:14.060
+comment les ordinateurs réussissent à détecter les erreurs
+et à les corriger.
+
+00:00:14.060 --> 00:00:20.380
+Levez la main si vous êtes déjà allés au supermarché
+et que vous avez scanné vos courses
+
+00:00:20.380 --> 00:00:22.920
+et que tous les articles s'affichaient ?
+
+00:00:22.920 --> 00:00:24.260
+Avez-vous déjà fait cela ?
+
+00:00:24.260 --> 00:00:24.940
+Oui ?
+
+00:00:24.950 --> 00:00:33.160
+Baissez les mains, donc que se passe-t-il quand vous scannez
+un produit et qu'il n'est pas lu correctement ?
+
+00:00:33.160 --> 00:00:35.240
+Que fait la personne à la caisse ?
+
+00:00:35.240 --> 00:00:38.540
+Ou que ferait la personne à la caisse ?
+
+00:00:38.540 --> 00:00:44.460
+Vous devez leur demander et ils vont scanner quelque chose ?
+
+00:00:44.460 --> 00:00:48.460
+Oui, ils scannent quelque chose, et parfois
+ils doivent saisir quelque chose au clavier non ?
+
+00:00:48.460 --> 00:00:52.320
+Ça peut ne pas être lu parce que le code barre
+peut être plié et ils doivent donc faire quelque chose
+
+00:00:52.320 --> 00:00:53.460
+que doivent-ils faire ?
+
+00:00:53.460 --> 00:00:57.980
+N'ont-ils pas quelque chose sur leur clavier, 
+N'ont-ils pas un machin à code barre.
+
+00:00:57.980 --> 00:01:01.760
+-- Oui ils ont ça.
+-- Et ils le scannent sur la machine
+
+00:01:01.760 --> 00:01:02.720
+et ça…
+
+00:01:02.720 --> 00:01:06.420
+C'est ça, mais ça ne nous dit toujours pas
+ce qu'est l'article.
+
+00:01:06.420 --> 00:01:12.020
+Donc en bas d'un article, il y a le
+code-barres ; en noir et blanc ?
+
+00:01:12.020 --> 00:01:14.480
+Mais il y a aussi des chiffres en dessous.
+
+00:01:14.480 --> 00:01:18.080
+Et ces chiffres ont quelque chose
+appelé une somme de contrôle à la fin.
+
+00:01:18.080 --> 00:01:18.840
+Oui ?
+
+00:01:18.840 --> 00:01:24.180
+C'est comme s'il y avait un code-barres qui était 
+un peu plus petit pour qu'il puisse être saisi par une personne.
+
+00:01:24.180 --> 00:01:25.420
+Oui oui tout à fait.
+
+00:01:25.420 --> 00:01:29.180
+Donc ils doivent taper les chiffres parce que
+la machine ne peut pas les lire correctement ?
+
+00:01:29.180 --> 00:01:34.300
+Donc le dernier chiffre est appelé "somme de contrôle"
+et je vais vous apprendre aujourd'hui comment ça fonctionne.
+
+00:01:34.300 --> 00:01:37.539
+Dylan, peux-tu aller chercher au fond de la classe 
+quelque chose qui…
+
+00:01:37.540 --> 00:01:41.260
+a un code-barres de 13 chiffres pour nous,
+et nous verrons comment ça fonctionne.
+
+00:01:45.260 --> 00:01:49.280
+Cool, donc lis-nous les chiffres tout haut
+mais je ne veux pas connaitre le 13e chiffre.
+
+00:01:49.280 --> 00:01:52.180
+Je veux seulement savoir les 12 premiers chiffres.
+
+00:01:52.180 --> 00:02:12.780
+9, 3, 1, 0, 4, 9, 2, 0, 0, 0, 4 et 5.
+
+00:02:12.780 --> 00:02:16.580
+Ok je vais juste te relire ça
+est-ce que tu peux vérifier ?
+
+00:02:16.580 --> 00:02:26.800
+9, 3, 1, 0, 4, 9, 2, 0, 0, 0, 0, 4, 5.
+
+00:02:26.800 --> 00:02:27.560
+C'est bon ?
+
+00:02:27.569 --> 00:02:28.569
+Cool.
+
+00:02:28.569 --> 00:02:32.310
+Ok maintenant nous avons ces chiffres sur le
+tableau, ce que je vais vous demander de faire
+
+00:02:32.310 --> 00:02:34.879
+c'est de m'aider à additionner la ligne du haut.
+
+00:02:34.880 --> 00:02:37.280
+-- Donc 9 + 1 font ?
+-- 10.
+
+00:02:37.280 --> 00:02:39.220
+-- 10 + 4 font ?
+-- 14.
+
+00:02:39.220 --> 00:02:41.760
+-- 14 + 2 ?
+-- 16.
+
+00:02:41.760 --> 00:02:45.580
+-- 16 + 4 ?
+-- 20.
+
+00:02:45.580 --> 00:02:52.050
+Et nous ne nous intéressons qu'à la colonne des unités,
+Quel est donc le chiffre dans la colonne des unités ?
+
+00:02:52.050 --> 00:02:53.050
+Sam ?
+
+00:02:53.050 --> 00:02:54.050
+2.
+
+00:02:54.050 --> 00:02:55.360
+C'est le chiffre des dizaines, bien essayé.
+
+00:02:55.360 --> 00:02:56.360
+Zéro ?
+
+00:02:56.360 --> 00:02:59.230
+Zéro, donc on va juste noter le zéro ici.
+
+00:02:59.230 --> 00:03:01.069
+Parce que c'est le seul chiffre
+qui nous intéresse.
+
+00:03:01.069 --> 00:03:02.980
+Maintenant nous allons additionner la ligne du bas.
+
+00:03:02.980 --> 00:03:05.360
+-- 3 + 0 font ?
+-- 3.
+
+00:03:05.360 --> 00:03:07.880
+-- 3 + 9 font ?
+-- 12.
+
+00:03:07.880 --> 00:03:12.120
+-- 12 + 0 font ?
+-- 12, 12.

+00:03:12.120 --> 00:03:14.560
+-- 12 + 5 font ?
+-- 17.
+
+00:03:14.560 --> 00:03:17.790
+17 mais on ne s'intéresse qu'à la colonne des unités ?
+
+00:03:17.790 --> 00:03:19.060
+7.
+
+00:03:19.060 --> 00:03:23.260
+Maintenant nous allons multiplier la ligne du bas par 3,
+mais attention.
+
+00:03:23.260 --> 00:03:25.060
+Nous nous intéressons seulement à la colonne des unités.
+
+00:03:25.060 --> 00:03:29.400
+Combien font 7 x 3 et quelle est
+la valeur des unités ?
+
+00:03:30.060 --> 00:03:30.900
+Freddy.
+
+00:03:30.900 --> 00:03:32.000
+1.
+
+00:03:32.000 --> 00:03:34.340
+Qui d'autre avait 1 ?
+
+00:03:34.340 --> 00:03:35.600
+Cool.
+
+00:03:36.580 --> 00:03:37.880
+C'est égal à 1.
+
+00:03:37.880 --> 00:03:39.520
+Combien font 0 + 1 ?
+
+00:03:40.780 --> 00:03:41.400
+1.
+
+00:03:41.400 --> 00:03:42.280
+Cool.
+
+00:03:42.280 --> 00:03:48.240
+Bien, si je devais faire
+0 — en fait ce serait un 10 — ok ?
+
+00:03:48.240 --> 00:03:51.040
+Parce que nous ne nous intéressons qu'aux unités.
+
+00:03:51.049 --> 00:03:56.459
+Si je devais faire 0, quel serait
+le chiffre manquant ici ?
+
+00:03:56.460 --> 00:03:57.880
+Zéro ?
+
+00:03:57.880 --> 00:04:00.340
+1 plus combien font 10 ?
+
+00:04:00.340 --> 00:04:01.620
+9.
+
+00:04:01.620 --> 00:04:05.180
+La somme de contrôle est 9.
+
+00:04:05.189 --> 00:04:06.659
+Vrai ou faux ?
+
+00:04:06.660 --> 00:04:07.500
+Vrai.
+
+00:04:07.500 --> 00:04:08.000
+Cool.
+
+00:04:08.000 --> 00:04:13.840
+Donc ceci est l'équation mathématique qui est
+derrière chaque code-barres.
+
+00:04:13.840 --> 00:04:19.520
+Ok, regardons ce qu'il se passe
+si j'entends quelque chose de faux.
+
+00:04:19.520 --> 00:04:23.380
+Supposons que j'ai entendu un 5 à la place du 4.
+
+00:04:23.380 --> 00:04:28.680
+Donc la première chose qui va changer est ceci,
+est-ce que ça resterait un zéro ?
+
+00:04:28.680 --> 00:04:30.460
+-- Non.
+-- Qu'est-ce que ça deviendrait ?
+
+00:04:30.460 --> 00:04:31.460
+1.
+
+00:04:31.460 --> 00:04:37.320
+Ok ce qui change le
+1+1 qui n'est plus 1, combien c'est ?
+
+00:04:37.320 --> 00:04:38.060
+2.
+
+00:04:38.060 --> 00:04:39.520
+Ça devient 2.
+
+00:04:39.520 --> 00:04:42.920
+Donc 2 plus combien font 10 ?
+
+00:04:42.920 --> 00:04:44.180
+Est-ce que c'est 9 ?
+
+00:04:44.180 --> 00:04:45.040
+Non.
+
+00:04:45.040 --> 00:04:47.420
+Ça devient 8.
+
+00:04:47.420 --> 00:04:54.160
+Et parce que j'ai écrit un faux chiffre,
+la somme de contrôle est incorrecte,
+
+00:04:54.160 --> 00:04:58.200
+et la machine vous dit que ce n'est pas correct.
+
+00:04:58.200 --> 00:05:00.520
+Et vous devez taper les chiffres une nouvelle fois.
+
+00:05:00.520 --> 00:05:05.360
+Et parce que nous sommes des humains, à votre avis
+quelle est l'erreur la plus commune
+
+00:05:05.360 --> 00:05:07.280
+quand nous tapons des chiffres ?
+
+00:05:07.280 --> 00:05:10.000
+Comment est-ce qu'on se tromperait le plus ?
+
+00:05:10.000 --> 00:05:11.770
+-- Robert ?
+-- Les chiffres.
+
+00:05:11.770 --> 00:05:16.200
+Oui les chiffres, qu'est-ce qu'on pourrait faire avec
+les chiffres qui les rendraient différents ?
+
+00:05:17.000 --> 00:05:19.320
+Ne pourrait-on pas tous les écrire ?
+
+00:05:19.320 --> 00:05:21.900
+Oui, est-ce que je lirais mal les chiffres ?
+
+00:05:21.910 --> 00:05:22.910
+Qu'est-ce que je ferais ?
+
+00:05:22.910 --> 00:05:28.410
+À la place de faire 9, 1,
+vous pourriez taper 1, 9.
+
+00:05:28.410 --> 00:05:34.750
+Oui, mais aviez-vous remarqué que celui-là était
+le premier chiffre, celui-ci le deuxième,
+
+00:05:34.750 --> 00:05:37.690
+celui-là est le premier chiffre,
+celui-ci le deuxième chiffre.
+
+00:05:37.690 --> 00:05:44.240
+C'est parce que l'erreur la plus commune
+que nous faisons est que nous échangeons 2 chiffres.
+
+00:05:44.940 --> 00:05:48.800
+Je pourrais lire 93, mais mes doigts taperaient 39.
+
+00:05:48.800 --> 00:05:50.800
+N'est-ce pas ? Avez-vous déjà fait ça quand vous tapez ?
+
+00:05:50.800 --> 00:05:52.840
+Et vous avez vos lettres dans le
+mauvais sens ?
+
+00:05:52.840 --> 00:06:00.100
+Et c'est pour ça : la somme de contrôle
+nous empêche de venir pour
+
+00:06:00.100 --> 00:06:06.520
+acheter un paquet de cartes Pokemon et de payer pour un ensemble de panneaux solaires pour robot.
+
+00:06:06.520 --> 00:06:07.280
+Ok ?

+Date: 01/10/2018
+
+00:00:05.060 --> 00:00:10.000
+[Réseaux de tri]
+
+00:00:11.480 --> 00:00:15.360
+Nous sommes donc allés dehors aujourd'hui
+pour comprendre un peu mieux comment fonctionnent les ordinateurs,
+
+00:00:15.360 --> 00:00:21.160
+et ce que nous avons ici, c'est un peu
+comme un supercalculateur fait à la craie.
+
+00:00:21.160 --> 00:00:24.919
+Et je vais vous montrer pourquoi dans un instant,
+j'ai besoin de six volontaires.
+
+00:00:24.919 --> 00:00:26.150
+Super.
+
+00:00:26.150 --> 00:00:30.710
+Ce que je vais faire c'est que je vais vous donner
+un disque, et vous allez devoir vous placer
+
+00:00:30.710 --> 00:00:33.430
+sur les cercles — les plus éloignés.
+
+00:00:33.430 --> 00:00:35.830
+Donc Rhylee tu vas sur
+celui qui est le plus éloigné.
+
+00:00:35.830 --> 00:00:39.090
+Robert tu vas sur le suivant.
+
+00:00:39.090 --> 00:00:42.900
+Ellie encore sur le suivant.
+
+00:00:42.900 --> 00:00:45.150
+Kourosh tu peux aller là-bas.
+
+00:00:45.150 --> 00:00:47.629
+Lewis tu peux aller sur le dernier.
+
+00:00:47.629 --> 00:00:48.629
+Ok !
+
+00:00:48.629 --> 00:00:52.219
+Donc vous êtes tous là, maintenant c'est
+un travail d'équipe.
+
+00:00:52.219 --> 00:00:55.850
+C'est aussi une question d'organisation des données.
+
+00:00:55.850 --> 00:00:59.460
+Donc vous êtes au début avec vos données
+et vous êtes tous désordonnés, nous avons
+
+00:00:59.460 --> 00:01:05.460
+le nombre 5, le nombre 2, le nombre 1,
+le nombre 3, le nombre 6 et le nombre 4.
+
+00:01:05.460 --> 00:01:10.680
+Et donc avant qu'on aille dans le supercalculateur,
+tout ce que je dois vous apprendre est ce symbole ici.
+
+00:01:10.680 --> 00:01:12.900
+Que signifie ce symbole ici ?
+
+00:01:12.900 --> 00:01:14.479
+Qu'est-ce que cela signifie Lewis ?
+
+00:01:14.480 --> 00:01:15.420
+Plus petit et plus grand.
+
+00:01:15.420 --> 00:01:19.940
+Plus petit et plus grand, quels autres termes
+mathématiques peut-on utiliser pour plus petit et plus grand
+
+00:01:19.940 --> 00:01:21.200
+-- oui ?
+-- Inférieur ou supérieur
+
+00:01:21.200 --> 00:01:27.100
+Inférieur ou supérieur. Super, donc ici
+la ligne orange est l'inférieur,
+
+00:01:27.100 --> 00:01:28.940
+et la ligne bleue est le supérieur.
+
+00:01:28.940 --> 00:01:33.560
+Donc voyons voir comment ça marche. Pouvez-vous tous
+avancer dans la boite.
+
+00:01:33.560 --> 00:01:37.980
+Pouvez-vous dire "bonjour" à votre voisin et
+lui faire un grand sourire.
+
+00:01:37.990 --> 00:01:39.100
+Pas trop mielleux.
+
+00:01:39.100 --> 00:01:42.500
+Maintenant vous devez décider : est-ce
+que j'ai le nombre le plus grand
+
+00:01:42.500 --> 00:01:44.600
+ou est-ce que j'ai le plus petit.
+
+00:01:44.600 --> 00:01:47.100
+Et le plus grand nombre
+suit la ligne bleue,
+
+00:01:47.100 --> 00:01:50.400
+le plus petit nombre suit la ligne orange, aller.
+
+00:01:51.120 --> 00:01:55.320
+Maintenant, vous devez regarder autour de vous et vérifier que tout le monde
+est là et dire bonjour et
+
+00:01:55.320 --> 00:01:58.000
+faire un grand sourire à votre voisin.
+
+00:01:58.000 --> 00:02:02.960
+Maintenant décidez qui a le plus petit, qui
+a le plus grand nombre.
+
+00:02:07.480 --> 00:02:08.640
+Est-ce que vous savez quoi faire ?
+
+00:02:08.649 --> 00:02:12.810
+On continue, je n'ai vu personne sourire et
+dire bonjour, souriez et dites bonjour.
+
+00:02:12.810 --> 00:02:13.810
+Salut.
+
+00:02:13.810 --> 00:02:15.980
+Maintenant, prenez votre décision.
+
+00:02:20.420 --> 00:02:21.260
+Bonjour !
+
+00:02:21.480 --> 00:02:22.120
+Bien.
+
+00:02:23.500 --> 00:02:24.660
+Quel nombre avez-vous ?
+
+00:02:25.840 --> 00:02:27.880
+J'ai le 4 alors je vais aller par ici.
+
+00:02:27.880 --> 00:02:28.860
+Parfait.
+
+00:02:33.980 --> 00:02:37.040
+Cool donc je vais vous demander de vous tourner et
+de me regarder et nous allons voir
+
+00:02:37.040 --> 00:02:40.860
+ce qu'il s'est passé avec les nombres, pouvez-vous vous tourner
+et montrer vos nombres s'il vous plait ?
+
+00:02:40.860 --> 00:02:44.000
+Oh, wow Kourosh quel nombre as-tu ?
+
+00:02:44.000 --> 00:02:45.360
+-- Un.
+-- Quel nombre as-tu Lewis ?
+
+00:02:45.360 --> 00:02:46.360
+Deux.
+
+00:02:46.360 --> 00:02:47.100
+Trois.
+
+00:02:47.100 --> 00:02:47.640

+Cinq.
+
+00:02:48.540 --> 00:02:49.280
+Six.
+
+00:02:49.280 --> 00:02:51.060
+Ok qu'est-il arrivé à nos nombres ?
+
+00:02:51.080 --> 00:02:55.520
+Nous les avons mis dans notre supercalculateur
+la craie c'est comme un supercalculateur,
+
+00:02:55.520 --> 00:02:58.480
+et nous les avons traités et que s'est-il passé ?
+
+00:02:59.140 --> 00:03:01.980
+Nous les avons retrouvés dans le bon ordre.
+
+00:03:01.980 --> 00:03:04.680
+Oh, est-ce que vous pensez que ça marche avec tout ?

+Oui, quoi d'autre ?
+
+00:03:17.400 --> 00:03:18.400
+Qu'en est-il des grand nombres ?
+
+00:03:18.409 --> 00:03:20.690
+Avec de très grands nombres est-ce qu'on pourrait faire pareil ?
+
+00:03:20.690 --> 00:03:22.020
+-- Oui.
+-- Oui, super.

+
+00:00:07.359 --> 00:00:19.100
+今天，我们将学习二进制数。
+你们听说过计算机中，一个叫“位”的东西吗？
+听说过的请举手。听说过吗？
+
+00:00:19.119 --> 00:00:30.900
+位 (bit) 是二进制数的简称。我们将二进制 (binary) 的首字母和数字 (digit) 的最后一个字母相结合，将二进制数 (binary digit) 缩写为位 (bit)。
+
+00:00:30.939 --> 00:00:36.600
+现在，这里有五位处于站立状态。
+大家看看，这意味着什么。
+
+00:00:36.660 --> 00:00:42.020
+我将给你数字 1，
+你将变成一个位，代表 1 个点。
+
+00:00:42.020 --> 00:00:44.530
+你将变成一个位，代表
+2 个点。
+
+00:00:44.530 --> 00:00:48.600
+下一个数字是什么？大声说出来。（4、3）
+
+00:00:48.600 --> 00:00:52.600
+认为是 3 的同学，请举手。那是我们的计数系统。
+
+00:00:52.600 --> 00:00:57.800
+让我们看看，你们在二进制上对不对。哦不！答案是 4。
+
+00:00:57.850 --> 00:01:07.800
+下一个数字可能是什么？嗯？（6 或 5）。
+它可能是 6 或 5。而实际上它是 8。
+
+00:01:07.800 --> 00:01:14.400
+这些数字有什么规律呢？Oliver，下一个数字是什么？(16) 他回答得对吗？
+
+00:01:14.430 --> 00:01:23.500
+16 之后又是哪个数字呢？Jacob (32) 哦，那么 32 之后呢？
+
+00:01:23.570 --> 00:01:32.100
+(136) 有可能哦，但还可能是什么呢？Lachlin (64) 他对了吗？（是的）。
+
+00:01:32.159 --> 00:01:42.300
+64 之后的数字是什么？Thomas (128) 那之后呢？Jacob？(256) 干得漂亮。
+
+00:01:42.300 --> 00:01:53.000
+有谁知道下一个数字是什么吗？Ben。(512)  所以，当我们……下一个数字呢 Jacob？
+
+00:01:53.000 --> 00:01:58.950
+因此，只需要用几个位，我们就可以
+数到很大的数字了，对吗？
+
+00:01:58.950 --> 00:02:07.070
+如果看这个的话，我们可以数到 1、2、4、8、
+16 个点。
+
+00:02:07.070 --> 00:02:20.600
+让我们看看，在计算机中，它意味着什么。位可能处于开启，也可能处于关闭状态。因此，这个位可能是开启，也可能是关闭。
+
+00:02:20.670 --> 00:02:29.900
+现在，我想让大家想出 31 和 1 之间的一个数字。想到数字的同学请举手。Ben，什么数字 (12)。
+
+00:02:29.930 --> 00:02:40.200
+12 现在需要看着这些点，并用二进制的方法表示 12 个点。我们应该开启还是关闭 16 呢？（关闭）。请关闭。
+
+00:02:40.209 --> 00:02:53.500
+如果要表示的是数字 12，我们应该开启还是关闭 8 呢？（开启）好的，还剩多少呢？(4) 我们需要开启还是关闭 4 个点呢？（开启）。
+
+00:02:53.550 --> 00:03:04.000
+2 怎么办？（关闭）为什么？为什么要关闭 2？（因为您已经用 8 和 4 表示 12 了）。因此，1 应该开启还是……？（关闭）
+
+00:03:04.060 --> 00:03:16.100
+谁可以告诉我二进制中 12 是什么，如何表示 12？谁要试着回答一下？（关闭、开启、开启、关闭、关闭）同意的话，请竖起你的大拇指。
+
+00:03:16.170 --> 00:03:21.850
+Elarn 认为如何呢，要表示一下吗？大家都可以先把自己开启了，
+
+00:03:21.850 --> 00:03:29.400
+Elarn，选一个你想要表示的数字。(24) 24 你可以先把自己开启吗？
+
+00:03:33.599 --> 00:03:45.670
+为了 24，我们应该开启还是关闭 16？（开启）8 开启
+或关闭（开启）4、（关闭）2（关闭）1（关闭）。
+
+00:03:45.670 --> 00:03:53.769
+Elarn，24 个点的二进制是怎样的？（开启、开启
+关闭、关闭、关闭）。
+
+00:03:53.769 --> 00:03:56.400
+大家可以给我表示一下 1 吗？我们应该怎么表示 1？
+
+00:03:56.470 --> 00:04:08.000
+可以如何表示数字 1？（黑色、黑色、黑色、黑色、白色）你们可以做到吗？
+
+00:04:08.000 --> 00:04:15.700
+现在，大家都看到数字 1 在那儿了。
+你们还能想到比 1 更小的数字吗？Will？
+
+00:04:15.769 --> 00:04:22.700
+(0) 你可以如何表示 0？（关闭白色）。
+
+00:04:22.720 --> 00:04:38.000
+我们可以表示最小数字零以及
+最大数字。如果你们再次把卡片全部开启，在有五位的情况下，我们可以
+表示的最大数字是多少？Ben？（31）同意 Ben 的同学请举手？它是 31。
+
+00:04:38.099 --> 00:04:49.300
+如果我们可以表示 31，那么下一张卡片的数字将会是多少？如果我加入其中，成为第六位，下一个数字会是多少？(32) 32。
+
+00:04:49.389 --> 00:05:00.000
+如果我把 32 打开，这些家伙都必须（关闭）
+关闭以表示 32。你们可以全部关闭吗？
+
+00:05:00.000 --> 00:05:03.879
+让我们做一些计数，看看不同的位
+会有什么情况。
+
+00:05:03.879 --> 00:05:12.600
+我们得到了零。应该如何表示 1？是的，给出指令（开启 1）。
+
+00:05:12.629 --> 00:05:23.800
+2，我们如何表示 2？告诉大家（关闭 1、开启 2）3？Lachlin，开始吧（开启 1，并保持 2 为开启状态）。
+
+00:05:23.800 --> 00:05:43.500
+4？（开启 2，关闭 1，再开启 4）5？（开启 1……）
+你注意到第一位有什么情况了吗？
+
+00:05:43.550 --> 00:05:50.000
+Zander，你注意到了哪些情况（它做了
+所有工作）。看起来它做了所有工作。
+
+00:05:50.099 --> 00:06:00.900
+为什么看起来它似乎做了所有工作？
+Ben？（没有它，你无法表示奇数）再次开启你的全部位。
+
+00:06:00.979 --> 00:06:07.699
+你看到的第一位和你能看到的其他所有位
+有什么区别？
+
+00:06:07.699 --> 00:06:16.439
+William？（数字 1 是仅有的奇数）它是仅有的奇数。
+
+00:06:16.439 --> 00:06:21.500
+我们可以表示很多数字，对吗？我想知道，可以如何表示字母？
+
+00:06:21.520 --> 00:06:31.580
+和身旁的小伙伴讨论
+你认为可以如何表示字母。
+
+00:06:31.580 --> 00:06:35.900
+你认为可以如何表示字母？
+
+00:06:51.080 --> 00:06:55.920
+5、4、3、2、1，看这边。
+
+00:06:56.000 --> 00:07:04.000
+想到该如何使用这些表示字母的同学
+请举手。你有什么想法？
+
+00:07:04.000 --> 00:07:19.200
+（可以用数字表示字母。26 可以表示 Z，A 可以表示 1）26 可以表示 Z，A 可以表示 1，那么 B 是什么呢？Jacob？
+
+00:07:19.270 --> 00:07:27.300
+(2)，C 是什么呢 (3)，那么 D 呢？(4)，E？(5)。我觉得你们已经理解相关的内容了。
+
+00:07:27.310 --> 00:07:35.600
+我想知道，你们是否清楚我给你们发的
+是什么。我将给你们发一条消息。
+
+00:07:35.669 --> 00:07:44.100
+黑色、白色、黑色、黑色、黑色。那是什么数字？(8)。
+
+00:07:44.129 --> 00:07:53.200
+字母表上的第八个字母是什么？(H)。记住它。
+
+00:07:53.229 --> 00:07:58.600
+关闭、开启、关闭、关闭、开启。得出什么数字？(9)
+
+00:07:58.669 --> 00:08:13.500
+Zander，我对你说什么了？（您对我们说的是“嗨”）是吗？你们同意他吗？我们打招呼了吗？
+
+00:08:13.520 --> 00:08:20.900
+但这些只是开启和关闭的点和卡，
+我真的可以通过这种方式，给你们传送一条消息吗？
+
+00:08:20.919 --> 00:08:38.000
+（是的）让我看看你们有多棒。大家看看我能不能表示
+我在哪个月份出生。准备好了吗？关闭、开启、开启、关闭、关闭。
+
+00:08:38.070 --> 00:08:44.500
+我在哪个月份出生？轻声告诉我，所以有很多人知道答案。
+开始。（十二月）答对了。
+
+00:08:44.510 --> 00:08:52.500
+因此，我们使用二进制数和使用这些点
+就可以传达从字母到数字的任何东西。
+
+00:08:52.540 --> 00:08:57.500
+你们甚至还可以用它们表示图像和声音，
+还有电影。
+
+00:08:57.500 --> 00:09:03.730
+所有涉及位的东西都可以，因为在计算机中，
+并没有太多像这样的卡片，
+
+00:09:03.730 --> 00:09:15.000
+并没有太多的零和一，
+但有很多需要开启或关闭的东西。
