In this study, we investigated the effect of type of positive interdependence (roles, rewards, roles-plus-rewards, or no structure) and affiliation motives (high vs. low) in an asynchronous, collaborative learning environment. College reentry students worked together in small, fully online discussion groups that lasted for seven days. Results…

This paper reports on the results of an action research to explore the effectiveness of using cooperative learning strategies on students' academic achievement, their understanding of physics concepts and their motivation to learn in the physics classroom. The study involved a secondary four express physics class of 41 students in a neighbourhood…

Simulated data were used to investigate the performance of modified versions of the Mantel-Haenszel and standardization methods of differential item functioning (DIF) analysis in computer-adaptive tests (CATs). Each "examinee" received 25 items out of a 75-item pool. A three-parameter logistic item response model was assumed, and…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

This self-instructional manual for psychological assessment focuses on the following topics: (1) general statistics, (2) central tendency, (3) random, continuous, and discrete variables, (4) variability, (5) measuring variability, (6) sampling, (7) derived scores, (8) covariation, (9) reliability and validity, and (10) standard error of…

Description of study to determine the impact of management training on student performance focuses on the need for proper evaluation. Pre- and posttraining evaluative tools for rating managers are described, differences in ratings are analyzed, and implications for evaluating management training on interpersonal skills are discussed. (LRW)

A study of correlations between analogical reasoning and Logo programming mastery among female high school students related the results of pretests of analogical reasoning to posttests of programming mastery. A significant correlation was found between analogical reasoning and the ability to write subprocedures for use in several different…

Describes study of undergraduates that examined uses and effects of learner control of the context or theme of practice examples on a computer-based statistics lesson in combination with the number of examples examined. Student attitudes are discussed, and correlations between learner characteristics and task outcomes are examined. (38 references)…

Discussion of children's comprehension of television focuses on a study in the United Kingdom that examined whether a successful course of television literacy could be developed for use with students from 5 to 12 years old. Treatments of experimental and control groups are explained, and correlations to other media are examined. (29 references)…

Discusses computer-based learning environments and presents results of empirical research on ESL (English-as-a-Second-Language) college students' work within a learning environment designed to help with elements of grammar. Topics addressed include illocutionary versus nonillocutionary natural language learning environments and correlations…

Effects on achievement of generating summaries or analogies while reading a lengthy text were studied for 111 undergraduate students randomly assigned to paired or individual conditions. Posttest results were higher for those who generated summaries, and students scored more highly working alone. Implications are discussed. (SLD)

In a large introductory physics course, structured weekly journals (weekly reports) regularly encouraged students to ask questions about the material. The resulting questions were collected for one quarter and coded based on difficulty and topic. Students also took several conceptual tests during the quarter. The reports contained more questions…

The purpose of the present study was to examine and compare the effectiveness of pre-teaching and re-teaching on math achievement and academic self-concept of third grade students identified as low achievers. A pretest-posttest experimental design was used to conduct the study. Results indicated that both pre-teaching and re-teaching resulted in…

This study is based on three distinct elementary cognitive tasks using chronometric techniques: (1) the S. Sternberg memory scan task, (2) a visual scan task; and (3) the Hick paradigm. Certain parameters of the tasks are compared experimentally and correlationally. Subjects were 48 university students, tested and retested on the tasks in a…

Feuerstein's mediated learning theory was applied to a deaf population for investigating the cognitive modifiability of this population. The learning Potential Assessment Device (LPAD) was employed for determining transfer of learning along cognitive and behavioral dimensions. Results showed that the groups who received examiner mediation…
