This thematic content analysis done about teaching biotechnology which is researched in Turkey is conducted with 64 articles, from a total of 45 magazines published in Turkey from 2003 to 2018. An analysis of the research trends of Turkish researchers based on teaching biotechnology. In this research, it has been tried to guide the researchers by…

This paper draws on data and experiences observing and analyzing school lotteries from the National Evaluation of Charter School Impacts (Gleason et al., 2010) to describe the challenges associated with lottery-based research. In that study, covering 36 charter middle schools in 15 states, we found that charter schools did not affect student…

In the context of "academic momentum," a longitudinal study of university students (N = 904) showed high school achievement and ongoing university achievement predicted subsequent achievement through university. However, the impact of high school achievement diminished, while additive effects of ongoing university achievement continued.…

For more than four decades the National Assessment of Educational Progress (NAEP) has tracked the achievement of U.S. students in major academic subjects. This national resource is the only assessment that states and now many urban districts can look to as an objective yardstick of their performance over time, relative to national benchmarks, and…

This paper, presented at the Fifth Annual Conference of the Australian Science Education Research Association in 1974, discusses the various strategies for analyzing the data gathered to explore the effect of specific school variables on educational achievement. The discussion centers around the International Association for the Evaluation of…

This paper demonstrates the variety of positive-skew phenomena and discusses their theoretical, research, and practical implications in education. (PN)

In the past few years, teacher training materials on behavior modification have emphasized precise behavioral measurement, and much classroom research has focused on the measurement of academic performance. The most common and simplest recording procedure advocated is frequency count. Difficulties can arise, however, when attempts are made to…

Reviews data related to the relationship between religious background and educational attainment for males and females during the second half of the twentieth century. Data indicate that the net influence of religious background on educational attainment has never been very large. (Author/DB)

Identifies shortcomings of single equation models of educational achievement, including that they have omitted relevant variables. Considers three models of educational achievement--one using cross-sectional data; one using pre- and post measures of achievement; and one using more complete panel data. (Author/DB)

Educational assessment concerns inference about students' knowledge, skills, and accomplishments. Because data are never so comprehensive and unequivocal as to ensure certitude, test theory evolved in part to address questions of weight, coverage, and import of data. The resulting concepts and techniques can be viewed as applications of more…

Educational research on the factors of student achievement has been limited by its failure to consider the multilevel or hierarchical nature of most data. This study used a nonexperimental regression-based procedure, hierarchical linear modeling (HLM), to empirically develop a predictive model of fifth-grade achievement in reading and mathematics…

Multiple sources of complications in the analysis of multilevel educational data are described with emphasis on the determination of a method of analysis that will provide accurate estimates of teacher/class effects even when there are systematic differences in within-class regressions of outcome on input associated with teacher/class…

In 1990, Milwaukee (Wisconsin) became the site of the first publicly funded school-choice program providing low-income parents with vouchers that could be used to send their children to secular, private schools. An evaluation of Milwaukee's school-choice experiment was conducted by a team of researchers, headed by John Witte at the University of…

Statewide assessment data available from two school years, two grade levels, and five sources (achievement tests; student, principal, and teacher questionnaires; and principal interviews), were aggregated to more closely investigate the relationship between student/school characteristics and student achievement. To organize this large number of…

In August 1996 Jay P. Greene, Paul E. Peterson, and Jiangtao Du, with Leesa Boeger and Curtis L. Frazier, issued a report called "The Effectiveness of School Choice in Milwaukee." The report, referred to as GPDBF, presented data that indicated that low-income minority students in their third and fourth years of participation in the…
