Descriptive analyses of socially important or theoretically interesting phenomena and trends are a vital component of research in the behavioral, social, economic, and health sciences. Such analyses yield reliable results when using representative individual participant data (IPD) from studies with complex survey designs, including educational…

The Programme for International Student Assessment (PISA) assesses the knowledge and skills in mathematics, reading and science of 15-year-old pupils in countries around the world. PISA is run by the Organisation for Economic Co-operation and Development (OECD), and assessment is typically undertaken every 3 years, allowing us to chart how…

This rejoinder keeps the original focus on statistical computing pertaining to the correlation of student achievement between mathematics and science from the Trend in Mathematics and Science Study (TIMSS). Albeit the availability of student performance data in TIMSS and the emphasis of the inter-subject connection in the Next Generation Science…

This chapter examines research on professional development, or PD, focusing specifically on underlying assumptions about the nature of teaching and the nature of teacher learning. It examines PD programs according to their assumptions about what teachers need to learn, and it examines PD studies according to how and when they expect to see…

The main aim of this research is to display research trends in studies on augmented reality (AR) in teaching English as a foreign language by using bibliometric mapping and content analysis. For this purpose, 64 studies in total published up to 2019 were accessed for bibliometric analysis. In addition, 49 articles published between 2007 and 2019…

To plan group-randomized trials where treatment conditions are assigned to schools, researchers need design parameters that provide information about between-school differences in outcomes as well as the amount of variance that can be explained by covariates at the student (L1) and school (L2) levels. Most previous research has offered these…

The aim of this paper is to discuss the role of coding and observation manuals in classroom studies. While observation manuals have been a part of the methodological toolkit for measuring various aspects of instruction for decades, the field has also been suffering from "paradigm wars," fragmentation and local production of instruments.…

Using meta-analytic techniques, we examined systematically the evidence linking friendship to academically related outcomes, asking: To what extent is friendship related to academic performance and to academically related cognitive skills? Based on 22 studies that yielded 81 effect sizes and 28 independent samples, we examined relations between…

An appropriate estimate of statistical power is critical for the design of intervention studies. Although the inclusion of a pretest covariate in the test of the primary outcome can increase statistical power, samples selected on the basis of pretest performance may demonstrate range restriction on the selection measure and other correlated…

The aim of this research is to examine the effect of Math worksheets based on the Multiple Intelligences Theory on the academic achievement of students in the 4th grade primary school. The sample of the research consists of 64 (32 experimental and 32 control) students who are studying in the 4th grade in a primary school affiliated to the Ministry…

A subset of students fail to respond adequately to reading interventions. This synthesis systematically reviews studies in which students in grades K-3 responded inadequately to a Tier 2 reading intervention and were provided with a Tier 3 intervention. Descriptions of the Tier 3 reading interventions and effects are provided. To meet inclusion…

For years scholars have attended to either generic or content-specific teaching practices attempting to understand instructional quality and its effects on student learning. Drawing on the TIMSS 2007 and 2011 databases, this exploratory study empirically tests the hypothesis that attending to both types of practices can help better explain student…

The study investigated the effect of using cooperative learning method on tenth grade students' learning achievement in biology and their attitude towards the subject in a Higher Secondary School in Bhutan. The study used a mixed method approach. The quantitative component included an experimental design where cooperative learning was the…

Little is known empirically about intraclass correlations (ICCs) for multisite cluster randomized trial (MSCRT) designs, particularly in science education. In this study, ICCs suitable for science achievement studies using a three-level (students in schools in districts) MSCRT design that block on district are estimated and examined. Estimates of…

Program for International Student Assessment results indicate that while reading comprehension needs to be promoted, teachers are struggling to find ways to motivate students to do reading comprehension activities and although technology-enhanced learning approaches are entering the classroom, researchers are still experimenting with them to…
