Power analysis of studies in Greene's meta-analysis of bilingual education programs found that many studies of the past 30 years were statistically weak and uninterpretable. Effect size analysis of Thomas and Collier's 15-year study found that their longitudinal model best explains 30 years of bilingual education research and can serve as a…

Examines whether the apprehension and perceived victimization risk of undergraduate students reading news reports depicting frequency of increases in threatening phenomena would be lowered by exposure to stories portraying population increases. Shows that the presentation of relevant population data can lessen the apprehensiveness associated with…

Asserts that journal's three studies examining cultural influences on emotional development reflect Western cultural model, using Western scripts for how data were collected and meaningfulness attributed. Addresses: (1) search for universals versus cultural specificity; (2) effect of unit of analysis; (3) whose perspective is used when proclaiming…

Presents an interdisciplinary activity that combines math and science and enhances cooperative learning skills. Enables students to learn about the scientific method by designing an original research project, collecting and interpreting data, and drawing conclusions based on their research. (JRH)

Twenty-four meta-analyses in mental retardation, learning disabilities, and emotional/behavior disorders were reviewed and analyzed across six domains of information necessary for securing face validity of published meta-analyses. Wide variations that could influence summative results were found. Additionally, temporal analysis of 44 meta-analyses…

School vouchers, particularly since the landmark U.S. Supreme Court ruling on the Cleveland program, are one of the most contentious issues in American education. Seemingly contradictory results across available studies have caused confusion among diverse audiences. The authors suggest that these divergent findings are, in part, due to three…

The present study used data from the Trends in International Mathematics and Science Study (TIMSS) 2003 to look at the trend in instructional strategies in science teaching and its effect on the science achievement. Based on the analysis, the strategies used by most science teachers were demonstration, practical work and the lecture method. Among…

Parents are increasingly drawn into school improvement as a key strategy to enhancing student achievement, but parents' understanding of their role is not well documented. This case study illuminates three Alberta (Canada) mothers' perspectives on the meaning of school improvement and their experiences within the provincially funded Alberta…

In the last decade, voluntary efforts by firms to reduce their environmental impacts have received increasing attention from both policymakers and scholars. This article discusses polluters' incentives to reduce their releases. In particular, using data from Canada's National Pollutant Release Inventory, it examines the impacts of conventional…

Statistical literacy is defined as "the ability to read and interpret data: the ability to use statistics as evidence in arguments. Statistical literacy is a competency: the ability to think critically about statistics" (Schield, p. 2). When a definition of statistical literacy is considered it can be seen that all students can manage a…

Education policy discussions often assume that public school teachers are poorly paid. Typically absent in these discussions about teacher pay, however, is any reference to systematic data on how much public school teachers are actually paid, especially relative to other occupations. Because discussions about teacher pay rarely reference these…

This paper analyzes trends in education expenditures in elementary and secondary schools, especially the extent to which special education costs are responsible for the overall upward expenditure trends. It reports on the limited national data available and on a longitudinal analysis of special education costs in Milwaukee, Wisconsin, from 1982-83…

Many students view statistics as their worst college course. Four heuristics that can improve students' proficiency in statistics and in interpreting reports of research are presented in this paper. The heuristics guide students' judgments about significance, generalizability, cause-and-effect, and strength of independent-dependent variable…

This paper presents findings from an historical investigation of visual literacy, a unique aspect being that the approach relied on the marriage of two disciplines--geography and history--which study change over time. Maps and their interpretation of data by cartographers tend to provide a foundational context that can illuminate past and present…

This manual presents 12 guidelines to help teachers of students with mental retardation make more informed decisions about instruction by gathering and using student performance data. Development of the guidelines incorporated both teachers' recommendations and researchers' findings about what procedures work best, and guidelines were tested in…
