Startower is created by Mike Matson. Startower is a package
of online quizzes made with dynamic html. The quizzes can be
downloaded as is, or you can download an html file to create
your own quizzes. I downloaded the 'worddrop.zip' file to create
some 'concordance quizzes'. Before you download anything, have
a look around this site to get an idea of how the quizzes work.
Please note, the Star Tower quizzes will
only work on browsers that can handle 'dynamic html' (i.e. Microsoft
Internet Explorer version 4 or above, or Netscape Navigator version
4 or above).
