Learn How: Create Your OwnGXWebAssessment Task

Geometry Expressions software offers many amazing opportunities for learning mathematics, even beyond its unique blending of constraint-based dynamic geometry and computer algebra. The ability to create GX documents and then

exportthese to a variety of formats is a powerful feature - the focus in these pages, of course, lies in exporting to the web, using HTML5 and JavaScript.When seeking to create

interactive online activitieswe demonstrate here that it is possible to go even further - using JavaScript toreadproperties from the embedded GX applet,and towriteto the applet from the web page.Of course, you might wonder

whysomeone would want to do these things. The examples shown in the Geometry Expressions Showcase demonstrate the power to create interactive assessment/exploration tasks perfect for online learning built around an embedded GX applet - students can even explore STEM applications using the in-built sensors on their mobile devices!Here we will consider four stages in opening up your embedded GX applet:

Creating your GX applet

Writing TO the applet

Reading FROM the applet

Putting it all together

to...

... and then to...

Stage 1: Build Your GX Applet

Stage 2: Writing TO your GX Applet

Stage 3: Reading FROM your GX Applet

Stage 4: Putting it All Together
