This study investigates the determinants of educational inequality between OECD and non-OECD countries using data from the PISA 2022 dataset. By focussing on factors such as parental education, perceived socioeconomic status, food security, and access to digital devices, the study provides a comprehensive analysis of how these variables impact…

The COVID-19 pandemic caused widespread disruptions to education, with school closures affecting over one billion children. These closures, aimed at reducing virus transmission, resulted in significant learning losses, particularly in mathematics and science. Using data from TIMSS 2023, which assesses fourth and eighth-grade achievements across 71…

The purpose of the study is to examine the impact of in-service education for early childhood teachers about scientific processing skills on young children's (5-6 year-old) science and mathematics performance and teachers' science teaching attitudes. A pretest-posttest with control group design was applied. From the treatment group nine teachers…

In this paper, we describe the development and preliminary assessment of ACORN Physics Tutorials, which are designed to elicit and build on common conceptual resources for understanding physics. We articulate our design principles and instructional commitments and how these bear out in the specifics of one ACORN Physics Tutorial about electric…

Reaction coordinate diagrams (RCDs) are an important tool used to visualize the energetics of a chemical reaction. RCDs provide information about the kinetics of the reaction, the mechanism by which the reaction occurs, and the relative thermodynamic stability of the molecules in a reaction. Previous research studies have characterized student…

Purpose: The research literature in this field demonstrates that instructional leadership provided by principals is essential for student learning, but the question of its impact on students with high and low socioeconomic status (SES) has remained largely unexplored. In the present study, the authors focus on the moderating role of instructional…

The end of college is a key transition point when students prepare for the workforce or graduate school, and when competence beliefs that have been shaped throughout college play a particularly important role in decision-making processes. This study examined the roles of two competence beliefs, self-efficacy for scientific tasks and science…

The purposes of the studies were: (1) to study the effects of the 6E learning model on grade 3 students' learning achievement in science with the determining criteria of 70; (2) to compare students' scientific creativity before and after implementing the 6E learning model; and (3) to evaluate grade 3 students' creative abilities after implementing…

The aim of this study is to determine the academic achievements of 8th graders in mathematics and science courses and STEM skill levels. The research has been carried out with the survey model. The sample of the study consists of 251 8th grade students in the 2020-2021 academic year. Math and Science academic achievement tests and STEM skill…

This meta-analysis examines the effects of game-based learning (GBL), compared with traditional instructional methods, on the science achievement of students, ranging from primary school to university. Results from the 41 primary studies of 6256 participants showed heterogeneity among effect sizes. The random effects model results showed a…

Analogies are bridges between prior knowledge and new knowledge to make meaning of the new one. Analogies are particularly effective in teaching science concepts that are not very apparent in the students' everyday lives due to their abstract nature. For this reason, it is essential to adapt analogies to teach new concepts effectively in science…

The area of interest considered for the study was the overall academic achievement in biology lecture and laboratory courses using Bloom's Taxonomy. The problem of the study is the lack of higher-order thinking skills leading to a learning gap in many universities and colleges. The purpose of the quantitative correlational study was to determine…

This study described the implementation procedure (step-by-step) of the culturo-techno-contextual approach (CTCA) in the classroom with concrete curricular examples for each step. The study then proceeded to explore the potency of CTCA on nuclear chemistry, a traditionally perceived difficult concept among secondary school students in Nigeria, as…

Active learning is known to improve student outcomes in many STEM courses. Here, we present strategies for incorporating active learning into a large enrollment General Chemistry I course using small group activities during class time. This approach was found to mitigate gender disparities in overall course grades and reduced the number of General…

Completion of a first-semester chemistry (Chem I) course lays the foundation for understanding second-semester chemistry (Chem II) topics. The purpose of this study is to evaluate the influence of basic arithmetic skills on students' Chem II success in understanding mathematics-grounded concepts (e.g., solutions and aqueous reactions, kinetics,…
