A general purpose computer program for the calculation of a matrix of tetrachoric correlations is described. This program was developed for use in adaptive (and other) testing research for examining the unidimensionality assumption in latent trait theory, in conjunction with available factor analysis programs. Several other potential applications,…

Describes a simple and inexpensive interface to be used for data acquisition and control of some experiments in an undergraduate physics laboratory. Two specific applications are presented. Seven references are listed. (Author/MBR)

These symposium papers discuss the instructional use of computers in psychology, with emphasis on computer-produced simulations. The first, by Rich Edwards, briefly outlines LABSIM, a general purpose system of FORTRAN programs which simulate data collection in more than a dozen experimental models in psychology and are designed to train students…

Describes the Monthly Data Grapher, a microcomputer program which helps visualize data to discern patterns and which is suitable for use with elementary school children. Some of its uses are noted and the microcomputer program itself is included. (MBR)

This report describes a study which used computer analyses of the center's film booking records for fiscal year 1981 to identify those subject areas in the collection for which holdings did not seem to accurately reflect the clientele's levels of interest, as indicated by their use of the collection. Results identified 60 subject areas which met…

The function and structure of a data base system called RIBYT (Review It Before You Test) is described. RIBYT simultaneously controls and associates questions in question pools for many courses of instruction. The data base stores questions created by both faculty and students and is used for formal testing and student self-assessment. The…

Characteristics of student financial aid systems are reported and a framework for evaluating student financial aid systems and classifying major data processing designs is presented. The goals of a student financial aid system are discussed, including improved service to students, increased utilization of available funds, compliance with…

A project was undertaken to develop a microcomputer program that would allow vocational agriculture instructors and students to enter information concerning a supervised occupational experience program (SOEP) into the computer. From there the program was to assist students to summarize that information from multiple entries and to print it out in…
