Characteristics of 11 Repgrid indices of cognitive structure, particularly Smith and Leach's hierarchical complexity index, are investigated among boys and girls, aged 9-15. The Smith & Leach index is shown to be significantly reliable; but in common with seven indices of cognitive differentiation, it is of dubious validity. (Author/GDC)

Instructions involving high-level questions and answers either were or were not given to fifth and sixth graders in three learning environments: cooperative, competitive, or independent. Students who received the instructions showed greater gains in recognizing and generating high-level questions. (GDC)

Laboratory and a field studies contrasted the egotism and expectancy-covariance approaches to attribution for achievement outcomes. Subjects' expectations and the basis of these expectations were varied and outcomes were then manipulated. Results supported egotism, suggesting that motivational factors can determine attributions to ability and task…

Two experiments examined problem solving in 16-month-olds' adaptive locomotion (crossing bridges of varying width with/without handrail). Findings indicated that toddlers attempted wide bridges more than narrow ones. Attempts on narrow bridges depended on handrail presence. Toddlers had longer latencies, examined bridge/handrail more closely, and…

Describes how a measure of problem difficulty (problem complexity) can be developed. Explores factors that may affect the difficulty of mathematics problems by focusing on ninth-grade student test responses (n=125), mathematics teacher questionnaire responses (n=29) in Hong Kong (China), and using a computer. Identifies four problem difficulty…

Reports the results of a survey that was conducted to determine the success achieved in increased reading of English associated with the use of graded readers for individualized reading in Japan. Recommendations are suggested for improving the program. (nine references) (GLR)

Focuses on the performance levels of the Test of English for Educational Purposes (TEEP) and English Language Testing Service (ELTS) tests. It is concluded that more attention should be paid to the process underlying test performance. (15 references) (GLR)

Reviews a study that was designed to find evidence of factors influencing the kind of interaction found in small-group work in language learning among young adult English teacher trainees in a developing country. (22 references) (GLR)

Attaining the insight needed to solve the Mutilated Checkerboard problem, which requires discovery of an effective problem representation (EPR), is described. Performance on insight problems can be predicted from the availability of generators and constraints in the search for an EPR. Data for 23 undergraduates were analyzed. (TJH)

Overall teaching effectiveness (OTE) was computed from student evaluations of teacher performance in a university business school. Class size, teaching assistants, and perception of class difficulty did not negatively affect OTE, but students' grade expectations had a significant influence. (SK)

Discussed is a report of a British government advisory group concerning programs of study in mathematics education, as related to students with special education needs. Described are the progression of levels, the spread of levels normal for particular age groups, and the notion of age determining the work of students. (JDD)

Experiments with 35 male/39 female college students and 220 male Navy recruits examined the nature of a general ability factor of intelligence--Spearman's "g." Patterns related to task complexity and reaction time variability were studied. "g" appears related to the ability to reconfigure working memory contents flexibly and…

The phenomenon of scale shrinkage is examined. Focus is on the pattern of decreasing variances in item response theory scale scores from fall to spring within a grade. It is demonstrated that questions concerning population distributions of true ability can be addressed with empirical Bayes techniques. (TJH)

A survey of Norwegian university faculty (n=1,815) shows significant differences between disciplines in time spent on teaching and preparation and in distribution of time between different types of teaching and teaching levels. It is proposed that some but not all of the differences may be due to characteristics of the disciplines. (Author/MSE)

The relationship between characteristics of test takers and characteristics of test items was examined in a quasiexperimental study involving 301 high school juniors and sophomores taking a mathematics examination that was consequential to sophomores but not juniors. Results are interpreted in relation to the expectancy value model of motivation.…
