Webdemos: An interactive, web-based visualization and simulation framework for open access

We introduce the web-based simulation and visualization tool Webdemo, designed for supplementing science, technology, engineering and mathematics (STEM) courses in higher education with interactive examples. The flexible simulation system supports a great variety of visualizations and mathematical operations. To ensure open access, the web front end does neither require additional software nor user registration and can be viewed on every device capable of web browsing. The creation of a new Webdemo based on the presented framework is simple and the reuse of templates guarantees a uniform and extensible user interface. A user survey confirms that students appreciate the Webdemos as a valuable enrichment of lectures.
