This software system was used to deliver 15 courses to inservice high schoolchemistry teachers. Over 500 graduate credits were earned during the period ofproject support, and delivery of the courses on a tuition-basis continues today.

Most of the course management was administered on-line, including studentregistration, course enrollment, delivery of all materials, and online testing. Theprincipal feature of the course was automatic testing, with assessment items deliveredin eight formats. Of these, seven were delivered for automatic assessment. The shortanswer item format included powerful worked out problem strategies such that, upon responding to a problem question, the student would see a worked solution to theproblem developed using his/her problem-specific information.
