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…

The goal of this research is to present the effects of virtual learning environments, specifically designed according to the problem-based learning approach (PBL) for 7th-grade students' science lessons. The effects of these specific environments on students' academic success, problem-solving skills and motivations were carefully analyzed and…

Amidst the challenges posed by the Covid-19 pandemic, this study investigates the impact of Problem-based Language Learning (PBLL) using DingTalk on enhancing Business English Writing skills among Chinese undergraduates. Employing a mixed-method approach, the research involved two phases. In the quantitative phase, a twelve-week quasi-experimental…

Best instructional methods are essential tools to bring desirable changes in pre-service science teachers. The available literature lacks enough meta-analytic review illustrating the effect of various instructional methods on pre-service science teachers' learning outcomes. This meta-analytic review identified instructional methods used for…
