This project helps introductory physics teachers develop the instructional, computing and laboratory interfacing skills needed to help their students learn physics by using the computer in the exploration of real-world phenomena. A two- week seminar is being offered in June 1993 and 1994 with 30 participants invited each summer. Topics covered will include: interactive instructional strategies based on outcomes of educational research; computer interfacing; use of spreadsheets and graphing packages; data and error analysis techniques; the application of laboratory interfacing real-time data analysis to lecture demonstrations; and numerical problem solving and modeling.
