Offers a critique on some of the papers on computers in science teaching that were presented at the 1985 National Association for Research in Science Teaching meeting. Implications for the conduct of research on computers in science learning are also suggested. (JN)

The substance of a commentary (SE 539 500) is a criticism of the over-generalizations by authors of computer-assisted instruction papers at the 1985 annual meeting of the National Association for Research in Science Teaching. This reaction attempts to examine the validity of the criticisms made in the commentary. (JN)

A mathematical model of information acquisition is presented and empirically evaluated in comparison to evidence obtained from experimental studies of science content acquisition. Implications of the model for human information acquisition and future research are discussed in the context of the unique theoretical framework of the model. (Author/JN)

Describes information-processing research, showing how computer models are used to explain thinking and how information processing approaches can be used systematically. Clarifies why students find factor-label method so difficult to master and discusses guidelines and suggestions for using information-processing ideas. (JM)

Discusses a mathematical model for mastery learning. The model includes measures of a motivational factor and the specific ability of a learner with respect to content being learned. The model also contains a variable reflecting prior learning. Assumptions/limitations are discussed, and research questions raised. (Author/JN)

Instrumentation, methodology, and analysis techniques were developed to measure changes in adolescents' (N=10) skills in linear distance estimation. Microcomputers were used to present and control amount of information available to assist students in said estimations. Results and implications are reported. (Author/SK)

Tested were all-verbal or verbal-pictorial presentations followed by either pictorial practice or a control task with 96 undergraduates; results favored pictorial presentation with review. Also tested were effectiveness of pictorial review tasks to a read-twice control with 50 different undergraduates. Pictorial review facilitated performance and…

Describes and evaluates science teachers' implementation of microcomputers at a field-test site that was part of a program to encourage literacy of science teachers in the use of microcomputers (ENLIST-Micros). Discusses why only 33 percent of the teachers used computers one year after the training. (Author/YP)
