One of the important aspects of learning and teaching through cooperation is the group composition or grouping "who with whom". An unresolved issue is that of the superiority of heterogeneity or homogeneity in the structure of the groups. The present study was an attempt to investigate the impact that homogeneous and heterogeneous…

Dialogic reading is an evidence-based practice for preschool children who are typically developing or at-risk; yet there is limited research to evaluate if it has similar positive effects on the language and preliteracy skills of children with disabilities. This quasi-experimental study examined the effects of dialogic reading, with the…

A dialogic storybook-based intervention integrating dialogic storybook reading with early literacy activities is studied with a longitudinal quasi-experimental study design. The effects of this intervention, in addition to a regular early childhood education (ECE) program, on kindergartners' vocabulary and phonological awareness development are…

Using a quasi-experimental design, the effects of a student support intervention were estimated for the math and reading achievement of first-generation immigrant children (n = 667, M = 11.05 years of age) attending high-poverty, urban elementary schools. The intervention was designed to help schools identify developmental strengths and barriers…

Online course-packs are marketed as improving grades in introductory-level coursework, yet it is unknown whether these course-packs can effectively replace, as opposed to supplement, in-class instruction. This study compared learning outcomes for Introductory Psychology students in hybrid and traditional sections, with hybrid sections replacing…

This article reports results from a large study comparing four different approaches to teaching Introduction to American Government: (1) traditional, a paper textbook with 100% face-to-face lecture-style teaching; (2) breakout, a paper textbook with 50% face-to-face lecture-style teaching and 50% face-to-face small-group breakout discussion…

The present study aims at examining the use of open-ended approach in cultivating senior high school students' mathematical creative thinking ability (MCTA) and self-esteem (SE) in mathematics viewed from school category. The subjects of this research were the students grade XI at three schools; high, middle and low category in Kota Serang, Banten…

The present study provides a report on an experiment seeking the effect of proactive intensive form-focused instruction on the grammatical development of intermediate and advanced Iranian EFL learners. More specifically the aim of the study was to discern (a) whether the grammatical knowledge of Iranian EFL learners at different proficiency levels…

Inability to link the acid-base concepts with daily life phenomena (as contexts) highlights the need for further research on the context-based acid-base chemistry. In this vein, the aim of this study is to investigate the effects of different teaching designs (REACT strategy, 5Es learning model and traditional (existing) instruction) relevant with…

The aim of this study is to determine the influence of inquiry-based teaching approach on pre-service science teachers' laboratory self-efficacy perceptions and scientific process skills. The quasi experimental model with pre-test-post-test control group design was used as an experimental design in this research. The sample of this study included…

Why are transfer students at an increased risk for disengagement and dropout? Previous research suggests that the loss of school-based social relationships play a role. Data from the National Longitudinal Study of Adolescent Health (Add Health) are used to analyze what predicts student transfer and what effect this has on students' social…

Numerous researchers in education recognize that vocabulary is essential in foreign language learning. However, students often encounter vocabulary that is difficult to remember. Providing effective vocabulary learning strategies is therefore more valuable than teaching students a large amount of vocabulary. The purpose of this study was to…

Using a longitudinal design, the present study examined whether two teaching concepts that varied in their capacity to foster students' self-determination affected students' sense of social relatedness and their perceived moderation competence, as well as the interplay between these two components and the students' performance during a moderation…

The integration of technology in mathematics instruction is an important step in the 21st century learning style. At the primary level, some studies have explored how technology could help in mathematics learning. The purpose of this study is to determine the effect of using Logo on pupils' learning of the properties of two-dimensional shapes. A…

As evidence becomes increasingly important in educational policy, it is essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. A total of 645 studies from 12 recent reviews of evaluations of preschool, reading, mathematics, and science programs were studied. Effect…
