In this section we look at how the Image_and_Cursor applet can be used together with HTML forms and Javascript to create highly interactive modules -- in particular, to create modules in which students can check their work by seeing the results rather than by looking up answers in the back of the book. The best way for you to start is by working through the instructions in the student-ready module, Describe the Squirt . If you want to cut to the chase without working through the problem, try pasting the following answers into the form on that page:
The following three brief documents explain how this module was created.
Complete documentation for the Image_and_Cursor applet is contained in the User's Manual. This applet is very flexible. Included among its features are controls for:
