Agile methodologies have become increasingly popular among software developers as evidenced by industrial participation at related conferences. The popularity of agile practices over traditional techniques partly stems from the fact that these practices provide for more customer involvement and better accommodate rapidly changing requirements,…

Examines human-computer interaction from two views of cognition: the representationist view and the enactivist perspective. A chaos-theory context is discussed from an enactivist stance. In this context, high school students manipulate nonlinear dynamic computer programs. Implications of the enactive stance for education and research are also…

Describes two expert programs including "One-Row NIM" and "TIC-TAC-TOE." Provides two programs written with BASIC and the explanations of the program. (YP)

Contains annotations for resources on the history of computing. Includes resources for technical computing history, general computing history, precomputer era, the impact of computing and series. (CW)

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

Examined is the use of the microcomputer as a tutor, for simulations of experiments, and to provide graphic interpretations of abstract concepts in the college biology setting. Discussed are computer enhanced courses being used, the software library, and the computer laboratory facility. Lists reasons for adoption of computer enhanced format. (MVL)

Discusses artificial intelligence, its definitions, and potential applications. Provides listings of Logo and BASIC versions for programs along with REM statements needed to make modifications for use with Apple computers. (RT)

Discusses the use of spreadsheets for problem solving in middle and elementary school math classes. Lists six ideas for their use in the classroom. Includes two templates. (MVL)

Presents a computer program which prints out a calendar corresponding to any year A.D. and states the objectives for such a program. Shows an example of a sample run. (RT)

Considers activities that use LOGO to slide, turn, and flip the "turtle." Uses non-LOGO tools such as cutouts, pattern blocks, and tangrams to enhance the motion work. Provides examples and programs with explanations. (MVL)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Surveys the current status of artificial intelligence (AI) technology. Discusses intelligent tutoring systems, robotics, and applications for educators. Likens the status of AI at present to that of aviation in the very early 1900s. States that educators need to be involved in future debates concerning AI. (CW)
