While several studies have investigated the various effects of open educational resources (OER) and open educational practices (OEP), few have focused on its connection to learning achievement. The related scientific literature is divided about the effects of OER and OEP with regards to their contribution to learning achievement. To address this…

Professional development for teachers is regarded as one of the principal pathways through which we can understand and cultivate effective teaching and improve student outcomes. A critical component of studies that seek to improve teaching through professional development is the detailed assessment of the intermediate teacher development processes…

The purpose of this study was to examine the overall effectiveness of the flipped classroom on students' learning achievement and motivation. Data were collected from three databases, which include Web of Science, Scopus, and Eric. The present meta-analysis synthesized the findings of 95 studies with 15,386 participants published from 2013 to…

Despite recent shifts in research emphasizing the value of carefully designed experiments, the number of studies of teacher professional development with rigorous designs has lagged behind its student outcome counterparts. We outline a framework for the design of group randomized trials (GRTs) with teachers' knowledge as the outcome and…

This article summarizes the creation and implementation of a concurrent support class for TRS 92--Intermediate Algebra, a developmental mathematics course at Fort Lewis College in Durango, Colorado. The concurrent course outlined in this article demonstrates a statistically significant increase in student success rates since its inception.…

This methodological brief introduces the readers to the propensity score matching method, which can be used for enhancing the validity of causal inferences in research situations involving nonexperimental design or observational research, or in situations where the benefits of an experimental design are not fully realized because of reasons beyond…

The intent of this study was to explore the effects of two settings on self-concept and school satisfaction of academically advanced high school students. The research designs were causal-comparative and correlational. Participants were 224 partial-day academic Governor's School students and 56 academically advanced students in district schools in…

Previous work on statistical power has discussed mainly single-level designs or 2-level balanced designs with random effects. Although balanced experiments are common, in practice balance cannot always be achieved. Work on class size is one example of unbalanced designs. This study provides methods for power analysis in 2-level unbalanced designs…

The primary purpose of this study was to examine the differences in teacher quality, student achievement, and graduation rates among select North Carolina urban high schools based on their racial segregation when measured by the entropy index. The entropy index is a measure of evenness among racial groups used to determine the level of segregation…

Learning communities are a popular strategy that community colleges nationwide have embraced in support of developmental students. In a learning community, a cohort of students takes two or more courses linked by integrated themes and assignments that are developed through ongoing faculty collaboration. While the number of learning community…

This study explored the bases for awarding incentive in a pay for performance system in Jamaica. The bases were generated by surveying the perspectives of a representative sample of teachers in the system at the time. The relative significance of emerging bases were examined through quantitative methods culminating in a set of criteria for…

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…

The No Child Left Behind Act (P.L. 107-110) called for the U.S. Department of Education to carry out a national study of the effectiveness of educational technology. With computers becoming ubiquitous in American schools, and purchases of hardware and software now substantial expenses for school districts, whether funding is supporting effective…

The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

The 1998 High School Transcript Study (HSTS) provides the U.S. Department of Education and other policymakers about current course offerings and students' course taking patterns. In 1998 the nationally representative sample for the HSTS included 25,422 students graduating in 1994 from 264 high schools. Approximately 94% of the sampled students…
