Explores mathematics results for seventh and eighth graders in South Africa on the Third International Mathematics and Science Study (TIMSS) test. Discusses reasons for South African students' relatively low performance by analyzing student background factors. Suggests research needs to study mathematics performance factors in more detail.

Investigated effects of two instructional interventions on 5- to 9-year-olds who could perform a balance beam task but either could not explain the principle or had naive theories. Found that more students who had observed the experimenter model and were then encouraged to explain what they saw improved performance over the pretest than students…

Compared results from computerized vocabulary tests under conditions in which item review was permitted or not permitted. Results from 177 college students reveal that performance gains after review were greater for examinees of high ability, and that review was desired more by examinees with higher test anxiety. The major drawback to review was…

Faced with the absence of a conceptual framework and the terminology for establishing evaluation criteria in the substance abuse prevention services field, this special issue is devoted to exploring the topics of accountability and performance measures. It discusses the requisite components (i.e., theory, methodology, convention on terms, data)…

Seventy-eight special-education students (ages 8-13) and 403 typical students took a large-scale statewide test using standard test administration procedures and two major accommodations addressing response conditions and test administration. No differences were found in the response conditions; however, students with disabilities who were read a…

Whether reader-generated illustrations are as effective as experimenter-provided illustrations in giving students the ability to understand scientific explanations was studied with 92 college freshmen. Students given illustrations and those who generated their own performed better on a test than students without illustrations, with no significant…

A scale to assess the goal of avoiding the demonstration of lack of ability (performance-avoid) was included with scales assessing approach goals for 703 sixth graders. Performance-avoid scales negatively predicted academic efficacy and positively predicted avoiding seeking help and test anxiety. Implications for goal theory are discussed. (SLD)

Two studies involving 160 kindergarten students investigated children's involvement in shared thinking with varying adult support and children's later performance on a categorization task. Results indicate that children benefit from working with an adult who provides some leadership in learning categorization skills. (SLD)

Studied the impact of practice tests on students' calibration and examination performance for multiple-choice and essay examinations. Results for 59 graduate students show that practice tests were associated with significantly lower scores on the midterm multiple-choice items and less accurate predictions and postdictions on these items. Discusses…

A four-year study explored face-to-face English competence of five students (ages 7-12) with deafness participating in a study of teachers' use of English-based signing. Grammatical forms similar in English and American Sign Language were initially more readily produced when tested for in English and students showed consistently higher attainment…

A study examined the contributions which families made to the success of 15 young adults with mental retardation in competitive employment. The following family characteristics led to more successful employment outcomes: moral support, practical assistance, role models of appropriate work ethic, protection from difficulties and exploitation, and…

Evaluated the effect of using the mastery learning techniques of self-directed feedback, reinforcement, and remediation of knowledge on the performance of a work-related task involving transfer of training. Supports the hypothesis that mastery learning would have a positive effect on transfer of knowledge from the classroom to a work-related task.…

The relationship between verbal and visual-spatial working memory and mathematical computation skill was examined in 98 children and adults with and without mathematical disabilities. A hierarchical regression analysis, when partialing for reading ability, age, and gender influences, showed mathematical computation was better predicted by verbal…

Tested in three experiments hypothesis that coordinating saying number-words and pointing to each object to count requires use of the central executive and that cost of coordination decreases with age. Found that for 5- and 9-year-olds and adults, manipulating difficulty of each component affected counting performance but did not make coordination…

Three experiments tested the ability of 11 children (ages 6-10) with low vision to recall black-and-white line drawings. Unlike fully sighted age-matched controls, children with low vision recalled best when left to study pictures without verbal intervention. They also named significantly fewer of the remembered pictures correctly. (Author/PB)
