This paper reports the findings of the second year of a four-year empirical research project. Its aim is to modify 'step-by-step' instructions for practical activities in a way that may enable the development of experimental design skills among junior high school learners. Each school year pupils spend six lessons doing practical activities using…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

The authors argue that playable fictions and analog game design can be an effective way to engage students in discussions about climate change and related scientific areas of exploration. They offer the example of a middle school climate science education unit grounded in the design, analysis, and play of board games and card games based on a…

The purpose of the present study was to explore the voices of high- and low-achieving middle school students around the function and utility of a student-engaged design learning how to learn intervention. The intervention was a year-long standard elective course in the curriculum in which all students enrolled during their time in middle school.…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

The spatial ability is defined as the combination of some abilities such as imagining the movements of objects, mental rotation, and spatial transformations. Students' spatial abilities can be enhanced through specific education programs. This study investigated the effects of engineering design-based instruction on spatial abilities of 8th grade…

Background: An efficacy study based on a randomized controlled trial (RCT) was designed to evaluate the impact of ASSISTments on math learning among middle school students, including those from high-needs rural schools. Despite extensive recruitment efforts in 2021 (during the pandemic), only a few schools and their teachers agreed to participate,…

This is a technical report detailing the analytic methods used to assess the effects of a virtual professional learning community (vPLC)-enhanced ASSISTments intervention. The report uses a quasi-experimental design and partially nested regression model to account for clustering and reveals that while overall effects were positive but not…

Access to quality secondary schooling can be life changing for students in developing contexts. In Kenya, entrance to such schools was historically determined by performance on a high-stakes exam. Understandably then, preparation for this exam is a priority for families and educators. To increase the share of students entering these schools, some…

This activity provides opportunities for middle school students to design bio-inspired, eco-friendly vehicles. Twenty-four 8th grade students (12 girls, 12 boys) engaged in the activity which was implemented in four class periods, 40 minutes each, in an elective Environmental Education course. During the activity, students engaged in engineering…

Using a framework for educational design research, this article reports and evaluates the (process of the) design of a financial education program. The program is designed for high school students in the prevocational track in the Netherlands. The aim of the program is to improve students' financial knowledge, attitudes, self-efficacy, and…

The researcher employed two designs to address the research question for this particular study. This quasi-experimental non-equivalent control group study compared the math achievement of 92 eighth grade students who received Classroom Performance System (CPS)-based instruction using Peer Instruction (PI) to 76 eighth grade students who received…

This study applied environmental behavioural theories to develop a personal carbon footprint management system and used persuasive technology to implement it. The system serves as an educational system to improve the determinants of students' low-carbon behaviours, to promote low-carbon concepts and to facilitate their carbon management. To assess…

Successful school reform is dependent on the quality of decisions made by educational leaders. In such decision making, educational leaders are charged with using sound research findings as the basis for choosing school reform initiatives. As part of the debate regarding the usability of various evaluative research designs in providing information…

The purpose of this quantitative, quasi-experimental study was to investigate the impact of a repeated reading fluency intervention focused on prosody, counterbalanced with an intervention focused on reading strategies. Both of these interventions were designed to promote feelings of achievement through participation in activities intended to…
