Peer reviewedStrommen, Erik F.; Frome, Francine S. – Educational Technology, Research and Development, 1993
Describes a study that examined the effectiveness of 1 configuration of automatic speech recognition software and hardware with 36 3 year olds and a comparison control group of 20 adults. The greater variability of children's speech is discussed; possible system modifications are considered; and future research is suggested. (18 references) (LRW)

Surber, John R.; Leeder, Jo Ann – Journal of Computer-Based Instruction, 1988
Describes study of fourth and fifth grade students which explained the effect of graphics on student motivation in a microcomputer-based spelling drill program. The role of feedback in instruction is discussed, the impact of graphics on computer software is described, and results are analyzed. (4 references) (LRW)

Peer reviewedVogel, Robert – Computers in the Schools, 1989
Criticizes the statistical methods used in a previously published article that compared a commercially produced computer program with traditional teaching methods. Measures of instructional effectiveness are described, the assignment of student pairs is examined, and the use of blocking variables with analysis of variance is discussed. (LRW)

Peer reviewedDalal, Nikunj P.; And Others – Journal of Educational Technology Systems, 1992
Discussion of the instructional effectiveness of educational software focuses on a study of undergraduates that investigated the effectiveness of a problem-solving program designed to assist students in solving nonlinear optimization problems. Results are reported that indicate manual procedures resulted in greater learning than use of the…
