This comparative study investigated the effect of supplementing problem-based learning (PBL) with video resources on students' academic achievement in physics, a unit of simple machines. It was carried out in the Ugandan Government and private lower secondary schools. The quasi-experimental design employed a cluster sampling design with 947…

This study aimed to juxtapose the impacts of the Problem-Based Learning (PBL) methodology implemented within a three-dimensional (3D) virtual environment against PBL in a conventional face-to-face setting, along with a control group, on students' learning performance, conceptual comprehension, and spatial aptitude. The investigation concentrated…

This study aimed to uncover common difficulties and possible areas for improvement by focusing on the approaches and errors made by 3rd-year undergraduate chemistry students in solving organic synthesis problems. The study employed a purposive sampling technique to select 112 undergraduate chemistry major students to participate in this study.…

Science identity, encompassing perceptions of competence, interest, and recognition in science, alongside learning self-efficacy reflecting confidence to master science skills, are key drivers of outcomes. However, developmental patterns likely vary across contexts. Participants were 512 Chinese students spanning grades 1-3 who completed the…

This study investigated the effectiveness of the orientation, identify, discussion, decision, and engage in behavior (OIDDE) learning model in enhancing biology learning outcomes, critical thinking, ethical attitudes, and engagement among high school students in Indonesia. Employing a quasi-experimental design with pre- and post-tests, the…

Engineering and integrated STEM experiences are being promoted at the K-12 level to increase interest and retention in STEM and to reinforce learning of mathematics and science content. However, research is still emerging regarding best practices for curriculum development, student impacts, and transfer of knowledge across disciplines. The purpose…

Previous work has looked at the relationship between high school preparation and student performance in calculus-based introductory mechanics (physics 1) courses. Here, we extend that work to look at performance in introductory calculus-based electricity and magnetism (physics 2), and we look at the significance of what college math courses have…

This study examined the effectiveness of instructional design to teach science concepts to visually impaired students. The study was conducted through case study. The study consisted of three stages. The first stage identified the visually impaired students' learning needs related to the concepts of the structure of matter. The second stage…

The purpose of this study was to examine the effectiveness of traditional versus guided inquiry (with problem-solving process and cognitive function training) on high school chemistry knowledge, science process skills, scientific attitudes, and problem-solving competency. Two classes of students were recruited from three classes of Grade 11…

This mixed methods study focuses on the use of instructional videos in an undergraduate physics classroom. Previous research has explored the effects of videos on student performance however, limited research exists on the effects of science instructional videos with embedded quiz questions on student achievement. This study compares students'…

The main aim of this research was to measure 10th and 12th grade students' biological conceptual understanding and competences through their upper secondary school studies. Data collection started at the beginning of the upper secondary school biology studies in the 10th grade. The same students participated in this research when they were in the…

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students' ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type…

A systems-based classroom intervention on environmental education was designed for seventh grade students; the results were evaluated to see its impact on the development of systems thinking skills and standard science achievement and whether the systems approach is a more effective way to teach environmental issues that are dynamic and complex. A…

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying "Electrochemistry" within a course on Analytical Chemistry. The research was of a pretest-posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at…

Students' ability to effectively study for an exam, or to manage their time during an exam, is related to their metacognitive capacity. Prior research has demonstrated the effective use of metacognitive strategies during learning and retrieval is related to content expertise. Students also make judgments of their own learning and of problem…
