Discusses problems with formative evaluation of educational materials and examines the slope test when used in a pretest/posttest multiple group (PPMG) design to adjust posttest scores treatment interaction studies. An example is given of the utility of the slope test and analysis of covariance procedure using an educational film about AIDS. (five…

Inconsistencies in the use of terminology to describe instructional treatments, confounding of discovery and expository methods with other aspects of instruction, and inconsistencies in defining independent and dependent variables within and between studies have all contributed to the lack of definitive conclusions about the effectiveness of…

One of the important components of the elaboration theory (Reigeluth, 1979) is the synthesizer, which provides information to relate and integrate a set of concepts and which can appear in different formats. This study investigated the effectiveness of three formats of post-instruction synthesizer on student recall of definitions of concepts and…

Describes study that examined text density levels as a design variable in print and computer-based instructional presentations. The six treatment groups are explained, including low density, high density, and learner controlled density; attitude surveys and achievement posttests are described; and implications of the findings for instructional…

Focusing on the achievement and motivational effects of analogies of varying enrichment levels when used with abstract, unfamiliar, and difficult content, this study examined their effects on instruction at the recall and application levels using content consisting of both concepts and principles. The subjects were 123 eighth-grade science…

Reviews study of undergraduates which evaluated the effects that variations in depth of information processing have on students' memory systems in terms of their ability to acquire and retrieve information related to different types of instructional objectives. The effect of visual versus verbal testing of visualized instruction is also examined.…

Discussion of conditions under which simulation games promote changes in attitudes focuses on identification theory as a predictor of attitude change. Incentive theory and cognitive dissonance theory are discussed, and a study of community college students is described that tested the role of identification in changing attitudes. (LRW)

A study of high school students learning computer programming was conducted to determine the impact of programming on particular mathematical and reasoning abilities, the cognitive skills or abilities that best predict programming ability, and what students actually understand about programming after two years of study. (MBR)

The attitudes of educators toward computers were assessed as well as their attitude change while taking an introductory microcomputer course. Sex and age differences were also investigated. Subjects included a sample who were surveyed by mail and a group of 22 teachers who were enrolled in a microcomputer course. A 44-item attitude questionnaire…

Discussion of the use of nonexamples as an effective strategy in teaching concepts focuses on a study of college students that explored the use of common errors to teach the procedure for color correction of color transparencies. Treatments for the experimental and control groups are described, and further research needs are indicated. (Author/LRW)

To better understand the effect of student background, work load, and attitudes on performance in intermediate algebra, a study was conducted in summer 1990 among students at a central Texas community college using pre- and post-course questionnaires completed by 124 of 157 students in 8 sections of intermediate algebra. Respondents were…

Describes study of 435 Israeli elementary school students to assess effects of open education on reading comprehension assignments. Literature on open education is reviewed, the hypotheses tested are described, results are analyzed comparing the effects of open education with the effects of traditional classroom instruction, and 46 references are…

Data were gathered, using pre and posttests and interviews, on the learning of individual students during a seven-week unit on a science topic (conservation) in a fourth grade classroom. Case studies of the learning experiences of each child, based on recordings and detailed observations of all class activities, were used to predict student…

This study examined the effects of the type of adjunct questions (use-a-generality, remember-a-generality, and remember-an-instance) and the position of these questions either before the relevant text passage (pre-questions) or after it (post-questions) on the three corresponding performance levels of learning. The subjects were 74 eighth-grade…

Students' macroprocessing of instruction was studied in a learning situation which used adjunct questions. The subjects were offered various macroprocessing options while reading a passage on data processing and computer programming. Each sentence appeared on a computer CRT screen one at a time. The options included: (1) review any sentence or…
