Astronomy education is essential for STEM education in primary schools, and integrating engineering design-based science education enhances student engagement and achievement in the field of space science. Integrating engineering design into science education is essential for students to excel in astronomy and to meet the requirements of…

Recently developed randomized-test procedures for two independent-samples single-case designs are presented and applied to a memory-strategy intervention study with eight underperforming students from low SES backgrounds. Research design aspects, data-analysis features, and various output measures are provided to demonstrate the potential utility…

These are the appendices for the report "The Effects of an Academic Language Program on Student Reading Outcomes." This study investigated WordGen Elementary, a program designed to improve fourth- and fifth-grade students' ability to understand and communicate academic language and their general reading skill. The program provider…

Due to the vast territory, there are problems of unbalanced development of education and students' ability level in China. In order to explore the relation between regional education equity and the development of students' scientific ability, and to better promote the development of education and students' growth, it is urgent to carry out the…

A key consideration in planning studies of community-based HIV education programs is identifying a sample size large enough to ensure a reasonable probability of detecting program effects if they exist. Sufficient sample sizes for community- or group-based designs are proportional to the correlation or similarity of individuals within communities.…

The aim of this study was to examine effectiveness of applying learning together (LT) method at different intervals on improvement of middle school students' academic success and science process skills. The sample of study consisted of 117 sixth and seventh grade students in two public middle schools. In this study, the "Solomon Experimental…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

"Research says…" a lot. But how does research come to say anything? One way is by having teachers open their classroom doors to a researcher. In this article, we share the stories of two teachers who opened their doors to the authors' research and were glad they did. The teachers contrast this experience to other research experiences in…

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…

Inquiry science instruction is especially challenging in elementary grades where teachers are constrained by crowded curricula and time. Professional development (PD) may provide an opportunity to support elementary teacher development of inquiry science instruction. The study examines the inquiry practice of two teachers who participated in an…

One obstacle to understanding abstract concepts such as the "control of variables" strategy (CVS) is the tendency for learners to focus on surface rather than deep features in instructional materials. However, in tasks such as learning CVS, these same surface features may also support understanding, provided learners realize the…

Educating children on a global level is a dynamic process where policy, procedure and guideline changes can leave teachers searching for new programs to resolve new challenges. This brief report shows a successful application of the Good Behavior Game in a school in the country of Belize following a significant change in policy regarding…

We present the results of a study of local education agency (LEA)-based interventions to improve the reading outcomes of struggling readers in sixth grade. The sample included 1,076 intervention students and 3,644 comparison students. Regression discontinuity was used to evaluate intervention impact. The study contributes to the field by…

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…

Design research studies provide significant opportunities to study new innovations and approaches and how they affect the forms of learning in complex classroom ecologies. This paper reports on a two-week long design research study with twelve 2nd through 4th graders using curricular materials and a tablet-based diagnostic assessment system, both…
