The purpose of this research was to design, create a prototype, and evaluate an Educational Data Acquisition System (EDAS) for use in secondary school science laboratories. The prototype of EDAS consisted of a microcomputer, data acquisition interface, sensors, software, and documentation. It provided the teacher and students with a…

The feasibility of guiding students of moderate aptitude to select appropriate learning strategies while they are learning an imaginary classification system was investigated in a study that contrasted the effect of system-assigned strategies for learning concepts with strategies selected by students. Subject-matter content was based on a set of…

Briefly describes a study of five New York City high schools conducted to determine the impact of microcomputers in schools. Interviews and surveys were used to address issues including student and teacher attitudes toward computers, teaching methods, teacher-student interactions, and differences between computer instruction and regular classes.…

Describes a study of the impact of different feedback types on secondary school students in which treatment groups received either corrective or noncorrective feedback. Results indicate no significant difference between the groups' posttest scores, but when groups were redefined by gender, girls receiving noncorrective feedback scored lower than…

Ninth-grade learners used one of three versions of an interactive video lesson on basic economics theory, one based on knowledge strategy, one on context strategy, and a control version without embedded questions. Results indicated context strategy was as effective as knowledge strategy for teaching declarative knowledge and more effective for…

The effectiveness of learning paired associates from a computer-based drill strategy known as the progressive state drill was compared in this study with the effectiveness of having students use their own strategies with flashcards. Characteristics of the progressive state drill which make it a potentially effective drill and practice strategy for…

Although some aspects of the educational effects of computer assisted instruction (CAI) are still unclear, some research findings are now quite definite. Two meta-analysis reviews of CAI have been completed at the University of Michigan, one on secondary school teaching and one on college teaching, and their findings have been independently…

An investigation of how secondary students coped when taught binary arithmetic through a computer assisted instruction program used four treatment groups: learner control, learner control with advice; random program control, and adaptive program control. The random group performed less well, but no differences were found between learner and…

Describes a study comparing learner control and program control, and the effects of giving learners information about their achievements in relation to criterion during instruction. Success was measured in terms of posttest scores, time on task, and number of instructional examples required. References are included. (Author/BK)

Describes a study of secondary school students in the Netherlands that compared the use of paper and pencil or computer spreadsheets to solve correlational problems in geography. Discusses results of videotape transcripts that compared teacher and student behaviors and considered mechanisms through which computers contribute to learning.…

Examines the importance of levels of questioning and types of feedback in designing courseware for computer-based education. Test results are analyzed for four groups of high school students who completed different versions of a computer-based science lesson, and recommendations for future research are given. (Author/LRW)

Describes a study that evaluated a network-based hypertext discussion tool (HDT) for teaching literature to adolescents by investigating whether the incorporation of the HDT into students' homework routine raised achievement over traditional discussion and text-based homework. Considers student feedback and attitudes toward learning with the HDT.…

This paper describes the general rationale, hypotheses, methodology, findings and implications of a recent dissertation research project conducted in the Columbus, Ohio, public schools. The computer-based study investigated the simultaneous relationship between achievement in microeconomics and attitude toward economics, level of computer anxiety,…

Conducted to determine whether use of computerized file-management programs can enhance the development of information processing skills, this two-treatment experiment found that seventh through twelfth grade students in the computer-using/structured activities group received significantly higher mean scores than the…

Describes study of high school students that was designed to determine the relative effectiveness of color, graphics, and animation in computer assisted learning (CAL) of a mathematical rule. Three CAL modes, in color and in black and white, are compared; pretests and posttests are explained; and further research needs are suggested. (13…
