Abstract : This paper is the culmination of a six month project begun in May 1996. The project involved researching, testing, and evaluating chemical demonstrations for a series of video tapes for a General Chemistry course. It was to be offered only a short 3 months from the original undertaking of the project. Background In Fall 1996, the University of Colorado at Denver offered for the first time an extended studies distance learning course for General Chemistry. The students who enrolled received seven video tapes which contained lecture material, demonstrations and visual aids. In addition, students received a course outline and printed lecture notes. The students were required to use a general chemistry text to accompany the course, but the course was designed so any general chemistry text would suffice. The students visited campus seven times during the semester for a long day of labs and testing. On-line help sessions were regularly scheduled with the instructor so the students could receive help working problems and understanding concepts. The advantages of a course like this are many. (1) It allows individuals to work at their own pace reviewing material when necessary and moving quickly through material with which they are comfortable. (2) With the many requirements of work and personal lives, students can work around complex family and employment schedules. (3) For parents who stay at home with their children, no sitter is required while the parent 'goes to class'. (4) Since many students live and/or work a great distance from campus, the travel time is significantly reduced by only having to come to campus seven times for this course. The disadvantages are the lack of external motivation from the regular presence of an instructor and the sometimes slower feedback loop.
