If the correlation between selection test and pretest is greater than the correlation between selection test and posttest, a selected group will continue to regress to the mean in the norm-referenced model of the Title I Evaluation and Reporting System and, therefore, yield a biased estimate.

Discussion of computer programming and knowledge-based instruction focuses on three studies of elementary and secondary school students which show that five particular problem-solving strategies can be developed in students explicitly taught the strategies and given practice applying them to solve LOGO programming problems. (Contains 53…

Describes the use of a computerized spreadsheet technique to assist in the front-end analysis phase of an instructional design project in an industrial training program. The use of a microcomputer is explained as a decision-making aid to analyze, select, and sequence instructional goals and objectives and to develop criterion performance measures.…

Reports the results of a study conducted at the University of York (England) that was designed to test the effectiveness of a concept mapping tool in aiding student learning from a hypertext-based computer-assisted instruction system. Effects on learning are compared with standard notetaking through results of a posttest. (Contains 17 references.)…

Discusses instructional analogies and describes two studies which were designed to examine the effects of instructional analogy training on college students' ability to identify the application of advanced physiological concepts. Student performances are compared with and without analogies and future research is suggested. (Contains 71…

Discussion of the use of microcomputers as word processors in basic writing classes highlights the improvements in students' writing skills. Changes in teachers' approaches to writing courses are discussed and results of a study of 24 students in a basic writing course using microcomputers at Montclair State College are presented. (Author/LRW)

Discusses the distinctions between formative and summative evaluation as they apply to instructional products (materials) and people (learners). Various terms for these four types of evaluation are mentioned, and their characteristics are described through examples from both educational and corporate instructional settings. (11 references)…

Describes a study that assessed the impact of four half-hour science programs for fourth graders aired on commercial radio in a causal-comparative between-groups study with prebroadcast and postbroadcast questionnaires. Formative and summative evaluation of the programs is described, and results are reviewed. (21 references) (LRW)

This study examined the relative effects of homogeneous versus heterogeneous ability grouping on performance and attitudes of students working cooperatively during interactive videodisc instruction. After two cooperative training sessions 80 fourth through sixth grade students, classified as high and low ability, were randomly assigned to…

Describes "Getting Clean with Herkimer," a software package designed to teach elementary special education students to classify personal grooming objects. A study compared this software program with another one, including results of pretests and posttests and computer use and attitude measures. (32 references) (LRW)

Describes a study of teacher education students at West Virginia University that was conducted to determine the effects of a computer-awareness learning module, instructional format, and prior computer use on computer anxiety. The relationships among performance, computer anxiety, and prior experience are also discussed. (Contains 12 references.)…

Describes a study that investigated the reliability, factorial validity, and fit to a unidimensional model of the Computer Attitude Scale based on pretests and posttests from 265 teachers who participated in training on classroom applications of computer hardware and software. Discussion includes computer anxiety, efficiency, liking, and…

Describes a study that was conducted at Tilburg University (The Netherlands) to test the impact of system and domain knowledge on search behavior in an online catalog. Highlights include time spent on task; the number of search patterns performed; and search patterns used most frequently. (11 references) (LRW)

Describes a study of undergraduates that investigated the effects of mental imagery during training on posttest scores. Speed of retrieval time versus accuracy is discussed; perception of imagery use is examined; and treatments of experimental and control groups are described. (23 references) (LRW)

Investigates a complex aptitude treatment interaction (ATI) of intelligence and metacognitive skill as aptitudes with structuredness of learning environment as treatment, based on a study of undergraduates in simulation environments. Highlights include computer-assisted learning and experiential learning; ATIs and discovery learning; and learning…
