Field tests were conducted to evaluate theory-based computer-video instructional modules designed to teach or review concepts and operations for factors, prime numbers, and fractions. (MNS)

Discusses flaws in the Apple IIe Applesoft random number generator, RND, and reports results of frequency and serial correlation tests of the generator. Suggestions of seeds that yield sequences of numbers which pass fundamental screening tests for randomness are presented. (Author/LRW)

Two field trials were conducted to test the effectiveness of instructional materials, which were presented on an Apple II Plus microcomputer interfaced with a videocassette recorder, in teaching mathematical skills to students who had not made normal progress in mathematics learning. In the first field trial, 58 experimental students from a high…

Theory-based prototype computer-video instructional modules were developed to serve as an instructional supplement for students experiencing difficulty in learning mathematics, with special consideration given to students underrepresented in mathematics (particularly women and minorities). Modules focused on concepts and operations for factors,…
