Describes an expert system microcomputer-based program, ZEERA, which is designed to help users understand and perform statistical analyses. Computer-assisted instruction and the traditional approach of drill and practice are discussed, and benefits of using ZEERA are described based on testing in a university elementary statistics course. (11…

This study of the application of cognitive style theory to the development of computer-based instruction explored two questions, i.e., whether computer-based courseware can be designed to address specific learner characteristics, and, if so, which characteristics. Several factors involved in the optimization of instruction are described: learner…

Four males, aged 11-18, who had poor achievement in mathematics, used the Lasermaths software program for practice and drill in basic arithmetic problems. After exposure to this program, which resembles a video game, subjects' performance on paper and pencil arithmetic tests was significantly improved. (GDC)

A study of 228 undergraduate psychology students examined the effectiveness of a prototype of "heatlab," a laboratory simulation written in PCE-PROLOG, intended for remedying misconceptions of the concepts "heat" and "temperature." The effect of varying the amount of structure on students' understanding and the…

The effects of microcomputer use on preschoolers' knowledge of pre-reading concepts and attitudes toward microcomputers were investigated. Seventy-seven preschoolers were randomly assigned to three treatment conditions: (1) adult-assisted microcomputer instruction; (2) unassisted microcomputer use; and (3) no computer use. Analysis of pretest…

Discussion of the use of color in microcomputer-based educational software focuses on a study of Israeli ninth graders that examined the differential effects of three color treatments on the learning of geometric concepts by students with differential aptitudes. Hypotheses tested are described and results are analyzed. (28 references) (Author/LRW)

Describes study that investigated the effectiveness of a computer-based study guide using hypertext software to increase textbook comprehension among four learning-disabled students in a remedial high school social studies class. Four levels of instructional cues are described that matched students to their highest level of independent interaction…

Describes Pathfinder, a microcomputer software package designed to improve students' understanding and skills in interpreting graphs of physical phenomena which was tested in high school math classes. Differences in strategies between various ability levels are reported, and student interactions based on observations and interviews are discussed.…

Discussion of computer-assisted instruction and cognitive style focuses on a study of college students that investigated the relationship of student success in algebra and field independence-dependence. Topics discussed include the effectiveness of computers as instructional tools; treatments for experimental and control groups; courseware; and…

Compared performance of low-aptitude remedial adults learning to solve mathematics word problems. Participants worked either alone or as collaborative dyads and received instruction/practice using either the Word Problem-Solving Environment (WPSE), an exploratory system over which learners exercise control, or Solver, a structured and directive…

The effects of different types of feedback in computer assisted instruction were studied in 30 college students with different cognitive styles. The program, written in Apple Pilot and administered on an Apple IIE microcomputer, consisted of 16 problem solving tasks; for each, a graphic display and a textual question were presented. Two feedback…
