After teaching the advanced spreadsheet course at a major university in Louisiana as a traditional classroom course for a number of years, it was decided to create a prototype-blended course, with a considerable portion offered via distance education. This research, which uses a prototyping methodology, is exploratory in nature. Prototyping can show that a design works, as well as where the design can be improved or enhanced. The traditional spreadsheet course had been taught in a highly structured fashion, with all students working on the same material at the same time. Students took exams at a specific time. With the change to a blended format, new teaching options and technologies opened up. This paper describes ongoing research for a new blended course using prototyping as the research methodology. Expected results from the new course include student skill level at the advanced level, improved student evaluations, and a decline in student withdrawals. (Contains 2 tables and 1 exhibit.)
