Results are presented from a study that implemented and assessed the effectiveness of a research-based model for training preservice secondary teaching trainees (N=97) in a complex teaching skill: clarity of explanation. Extensive discussion is presented on the study design and implementation. (IAH)

Results of a study which tested the effect of four instructional strategies on students' (N=138) writing indicate that the most effective instructional strategy for informational writing was presentation of model pieces of writing, followed by free writing. (IAH)

Results are reported from a study which showed that activating competent readers' naive conceptions about a complex science concept is not as effective in dispelling inaccurate information as activating their naive conceptions and then explicitly directing them to read and attend to ideas that might differ from their own. (IAH)

This study compares the effect on instruction of two strategies used by special education teachers (N=22) to monitor reading skills development. One strategy used only the overall performance indicator from a written recall measure; the other used this indicator in conjunction with a more qualitative analysis of student protocols. (IAH)

Findings from an investigation into the effectiveness of an explicit training model on low socioeconomic (SES) four- and five-year-old's (N=26) ability to solve geometric analogy problems suggest that higher level cognitive skills of low SES preschoolers can be enhanced through instruction. (IAH)

Study findings indicate that exposure to a statement on a true-false test increased college students' (N=64) tendency to believe the statement was true, regardless of whether the statement actually was true or false. In contrast to previous research, these findings support existence of a negative suggestion effect for true-false exams. (IAH)

This literature review discusses factors affecting women's participation and achievement in formal education systems in the Third World and factors contributing to gender inequalities in education. Cultural, social, and economic factors are identified; and recommendations for the expansion and improvement research are made. (TJH)

A meta-analysis of studies conducted between 1974 and mid-1987 on sex differences in mathematical tasks is presented. Methods used include estimations of: (1) parameters for a random effects model, and (2) coefficients for a linear-regression equation, all based on effect sizes calculated from each study. Differences have been decreasing. (TJH)

A descriptive analysis of research practices and a meta-analysis of control group effect sizes are used to address Hawthorne effects in educational experiments. The analysis of 86 studies and 256 treatment/Hawthorne/no-treatment control group effect size comparisons indicate that artifact controls have limited utility in dealing with the Hawthorne…

Two papers respond to an article by P. Atkinson, S. Delamont, and M. Hammersley (1988) critiquing papers by E. Jacob (1987, 1988) on qualitative research traditions. The use of T. Kuhn's concept of "paradigm" and the criticism that the British were not included in the Jacob's study are addressed. (TJH)

An assessment is provided of two papers responding to an article by P. Atkinson, S. Delamont, and M. Hammersley (1988) critiquing papers by E. Jacob (1987, 1988) on qualitative research traditions. Definitions of "tradition" and "research tradition," and the necessity to include British research in Jacob's meta-analysis are discussed. (TJH)

Three case studies in southern California explore the effects of parental involvement on a child's reading achievement through the parent's influence over reading group placement. Two Hispanic first-graders improved substantially when their parents took actions explicitly related to reading group placement; a third remained in a low reading group.…

A hierarchical linear model analysis investigated the effects of structural and normative features of schools on absenteeism and the probability of dropping out. Subjects included 4,450 sophomores in 160 Catholic and public high schools from the High School and Beyond 1980 cohort. (SLD)

Associations among background, commitment levels, institutional involvement, and student persistence were studied for 260 out of 323 early college dropouts. The model of attrition developed by V. Tinto (1975) was applied. Student persistence was found to vary by motivational type and student's psychosocial orientation to college. (SLD)

Teachers' styles of textbook use were identified, and the overlap between content taught and textbook content in elementary school mathematics was studied for four teachers in four Michigan fourth grades. In each classroom there were important differences between text content and teacher's topic selection, content emphasis, and sequence of…
