The final applet I will present is an example of what I call a "theme
applet". This is the most ambitious type of project where a whole
course revolves around an applet that appears and reappears in different
contexts. In this example the applet presents an &qoot;overhead photograph"
of a forest. Green dots are healthy trees and red ones are diseased trees.
The light green patches are grass. The applet is meant for an elementary
statistics class. The version of the applet I show takes a sample, gives
you the statistics and you (the student) are expected to estimate confidence
intervals for the proportion of the trees that are diseased.
One could weave a course around a collection of such applets, with
different applets providing different problems and data for consideration.
