A study investigated the effect of reward on sixth graders' self-correction inaccuracy and monitored the effect of improved self-correction on mathematics homework achievement. There was a low baseline rate of student self-correction inaccuracy. Offering a reward for improved accuracy caused the rate of inaccuracy to decrease significantly.…

Ways in which scientists and science students respond to anomalous data are analyzed. There are seven distinct ways in which they respond, only one of which is to accept the data and change theories. Factors that influence theory change and implications for science instruction are reviewed. (SLD)

Empirical research on the role of school recess is reviewed. Effects of child-level and school-level variables on recess behavior and the impact of recess on classroom behavior and social and cognitive competence are discussed. It is concluded that recess has important educational and developmental implications. (SLD)

This metanalysis reviews 32 studies that compared 2 groups of students receiving identical writing instruction, with only 1 group using word processing for writing assignments. Word processing improved the quality of student writing but did not improve student attitudes. Suggestions are given for using word processing more effectively. (SLD)

Analyzes effect sizes in tails of distribution of scores in Feingold's study of joint effects of gender differences in mean and variability on 28 cognitive-ability scales. Effect sizes are smaller than Feingold assumed. Evaluates joint effect of gender differences by number of males and females in extreme score ranges. (SLD)

The second approach used by L. V. Hedges and L. Friedman (1993) in their reanalysis of Feingold's earlier results is conceptually equivalent and yields results consistent with the original interpretation. The first method yields results that are discrepant. Analyses of variations in tail effect sizes are planned. (SLD)

Feingold's reply illustrates that his steps in characterizing tail effect sizes are not the calculations the authors had imagined. Attempting to reproduce Feingold's calculations, the authors still often find themselves in disagreement with interpretations Feingold has placed in his table. (SLD)

Relationships between high school structural characteristics and curricular offerings are examined using data from the High School and Beyond Survey, with an emphasis on school size. Findings are consistent with the hypothesis that effects of size are differentiated within high schools. Implications for equality of education are discussed. (SLD)

How power, in the caring perspective, can be seen as moral authority is explored in an ethnographic study of the traditional teacher-centered classroom of a second-grade teacher. Routine and ritual established continuity for curriculum and instruction. The purposes of collective responsibility and work were continuous. (SLD)

A general overview is provided of the structural transformation of work from a goods-based to a services-based economy, and suggestions are offered for reconsidering educational reform policy in light of the demand for schooling the new structure creates. The central problem of educational reform has become facilitating critical thinking. (SLD)

The influence of mathematics-specific teaching practices on class-level mathematics achievement was studied using Second International Mathematics Study data for 236 eighth-grade classes (approximately 7,000 students). Links between class characteristics and teaching practices are explored. High socioeconomic status and high-ability students…

Effects of adult mediation and literacy-enriched play settings in Head Start classrooms on environmental and functional print tasks were studied for 177 minority preschoolers in poverty. Results indicate that the active engagement of adult mediators in literacy-enriched office play settings influenced children's ability to read environmental…

A process for readying students to change from special education to regular mathematics classrooms was implemented and validated in a study involving 42 students with mild disabilities in experimental and control groups. Preparation appeared to enhance achievement while in special education, but not in the regular class. (SLD)

A 3-year study in 8 middle schools tested a program to improve adolescent conduct. The program attempted to improve clarity and enforcement of rules, classroom organization, school-home communication, and increase reinforcement of positive behavior. Where it was well-implemented, student conduct improved significantly. (SLD)

The effectiveness of students' evaluations of teaching effectiveness (SETs) as a means of enhancing university teaching was evaluated using the self-evaluations of 92 teachers and their students' evaluations using the Students' Evaluations of Educational Quality instrument. Results support the effectiveness of SET feedback in improving teaching.…
