The Apple II microcomputer program described allows instructors with minimal programing experience to construct computer models of psychological phenomena for students to investigate. Use of these models eliminates need to maintain/house/breed animals or purchase sophisticated laboratory equipment. Several content models are also described,…

Presents a laboratory experiment that was developed to acquaint physics students with field-effect transistor characteristics and circuits. Computer-drawn curves supplementing student laboratory exercises can be generated to provide more permanent, usable data than those taken from a curve tracer. (HM)

Described is the use of two models of pocket calculators. The Hewlett-Packard HP67 and the Texas Instruments TI59, to solve problems arising in connection with ionic equilibria in solution. A three-parameter regression program is described and listed as a specific example, the hydrolysis of hexavalent uranium, is provided. (BT)
