Easy Java Simulations (EJS) are a way to create Java Applets to showcase scientific labs and experiments on a computer. The EJSApp is a Moodle Addon (actually 4 plugins as a set) that allows the labs and simulations to be displayed and used right in your Moodle classroom,
Easy Java Simulations (EJS, http://www.um.es/fem/EjsWiki/pmwiki.php) is a tool designed for the creation of discrete computer simulations. During the last few years, EJS has grown for helping to create web-accessible labs in education of scientific and technical disciplines. With this objective in mind, recent releases of EJS support connections with external applications, such as LabView and Matlab/Simulink. Hence, EJS not only is useful to create virtual labs, but also the GUIs of their remote counterparts.
The app brings these labs/simulations together with Moodle for a seamless online experience in the classroom. What more could you want? Grab the code for the app here and learn more: https://moodle.org/plugins/view.php?plugin=mod_ejsapp
