Sequencer is about teaching ordered events and sequences. Items are presented to students in a random order for them to re-arrange. Sequencer is designed for use with Materia, an open-source platform for interactive course content developed by the University of Central Florida.
In a production evironment, Sequencer is installed to your Materia instance and is accessed via the Widget Catalog. For development, Sequencer is bundled with the Materia Widget Development Kit, which allows for rapid development in a local context using express.js.
Sequencer uses the Materia Widget Development Kit for local development. Check out the docs for the MDK to learn more about starting up the local express environment.
Widget installation options are covered in the Installing Widgets section of the Materia Docs.
For more information about the widget development process, be sure to visit the widget developer guide for Materia.
