There exist passionate debates about the best way to teach children to read. Since the Bush administration, school districts receiving federal funds have been required to have research evidence justifying their methods of teaching reading, and in recent years the need for evidence-based practices have intensified with the "Science of…

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

The present study contributes to the development of effective measures to evaluate classroom climate, especially in elementary education where these remain limited. In addition, it addresses a typical "flaw" of several studies by approaching classroom climate as a group-level construct rather than an individual characteristic. Following…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016. Of 30 studies that met inclusion criteria and had data from which an effect size estimate could be calculated, 7 reported science outcomes (18 effect size estimates) or…

This study utilised regression methods to explain Grade 4 reading literacy achievement taking into account discrepancies between the language of the test and home language for learners who participated in the South African preProgress in International Reading Literacy Study (prePIRLS) 2011. Grade 4 learners were tested across all 11 official…

This paper reviews prior research to assess the effectiveness of Title I in closing the achievement gaps of disadvantaged students vis-à-vis their non-disadvantaged counterparts. A research synthesis approach is adopted to summarize national assessments of Title I conducted between 1966 and 2011. These analyses are supplemented by the authors'…

Many elementary science teachers understand that the best way to enhance reasoning and thinking skills in their students is to have them engage in scientific negotiation. They know that teaching is not the simple transmission of information but a complex act that requires teachers to apply knowledge from multiple sources, including student…

This research explored how Karen (first-generation refugees from Burma) elementary students engaged with the Next Generation Science Standards (NGSS) practice of constructing scientific explanations based on evidence within the context of a cross-cultural learning community. In this action research, the researcher and a Karen parent served as…

Teacher observations have become a national education phenomenon, mandated by federal policies and promoted by philanthropists. They are crucial components of teacher evaluation systems that often have high stakes for teachers and school systems, but have sparked little innovation. Recent calls to make teacher evaluations better, faster, and…

In supporting students toward literacy, teachers must provide experiences that support the formation of informed understandings of the nature of science (NOS), as well as a structure for developing evidence-based explanations. In this article the authors describe how they guided their students through this learning cycle to answer the essential…

Class size reduction policies have been widely implemented around the world in recent years. However, findings about the effects of class size on student achievement have been mixed. This study examines class size effects on fourth-grade mathematics achievement in 14 European countries using data from TIMSS (Trends in International Mathematics and…

As is the case in most OECD countries, boys in Norway are more likely to have lower levels of academic achievement and attainment than girls. While this phenomenon is not recent, it has become increasingly pronounced in recent years and, as a result, is attracting considerable attention from policy-makers in many countries. This paper develops…

Class size reduction has been viewed as one school mechanism that can improve student achievement. Nonetheless, the literature has reported mixed findings about class size effects. We used 4th- and 8th-grade data from TIMSS 2003 and 2007 to examine the association between class size and mathematics achievement in public schools in Cyprus. We…

This Center for American Progress report examines whether states' adoption of standards-based policies predicts low-income students' NAEP achievement trends in fourth and eighth grade math and reading throughout the 2003-2013 decade. The report claims to analyze changes across five separate two-year intervals, but it only reports findings for…

Background: In Ohio, 14.5% of 5- to 9-year-olds and 17.3% of 10- to 17-year-olds have asthma. Moreover, there is concern that these numbers may underestimate the true disease burden. We sought to evaluate variability in asthma rates and respiratory symptoms among central Ohio fourth graders as a means to assess potential undiagnosed and…
