An intuitive approach to exponential functions is described. Microcomputers are used to aid discovery of derivatives. (MNS)

Uses Derive as an instructional tool to investigate asymptotic behavior of rational functions. Activities focus on reducing manipulation and computation and on generating multiple examples to focus on discovery of the concept rather than a summary of rules. (MLN)

Maintains that most computer tutorials retain a print orientation substituting connected computer screens for the pages of a book. Argues for a more creative use of computers' interactive capability. Presents three model tutorials concerning the Maastricht Treaty and U.S. Constitutional ratification. (MJP)

Examples of composite functions present students with intriguing questions that they can explore using calculators and computers, geometric and algebraic methods, and approximation techniques. Student-centered activities allow students to make discoveries about functions. (MLN)

Adventure games designed for use on home computers are a potentially powerful instructional resource in English as a second language because they promote problem-solving using the target language and are highly motivating to students. The games, whose objective is usually for the user to defeat an obscure force and recover a precious object, are…
