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…

The purpose of this study was to introduce technology-based EIGEC models and implement these models into the learning process in the classroom. This research was quasi-experimental, using a pre-test-post-test control group design. The research sample consisted of two classes with different treatments. Each course was selected randomly, with the…

This study aimed at analyzing the impact of problem-based learning (PBL) in improving physics students' conceptual understanding of mechanical waves. This study used a quasiexperimental, pretest-post-test control group design with PBL instruction as a teaching intervention. The participants of this study were 239 physics students from 19 secondary…

This study aimed to assess the impact of problem-based learning (PBL) on students' achievement in mechanical waves among secondary schools in South Western Uganda. Four hundred and nineteen students (419) from 19 schools were involved in this study. A quasi-experimental research method was employed through Solomon's four-group design. Form six…

Various similar primary studies report varying impacts of applying blended problem-based learning (Blended PBL) in improving students' 21st-century skills. This study aims to group similar studies on the effect of blended PBL on students' 21st-century skills in science learning through meta-analysis. In addition, studies were analyzed on…

The limited time allocation for lectures in the classroom is an obstacle to presenting student-centered learning. This is one of the factors that prospective physics teacher students experience conceptual difficulties, especially in crystal structure material. So the purpose of this study was to determine the effectiveness of the problem flipped…

This study is aimed to investigate the effectiveness of problem-based learning combined with simulation on students' problem-solving and creative thinking skills. By employing a quasi-experimental design, this study used essay and problem-based tests as the instruments to evaluate problem-solving and creative thinking skills of 192 students. These…

Newton's third law of motion is probably one of the easiest and simplest laws in physics for students to recite. However, when they are given questions where they must apply the understanding of the law to solve a problem, it often becomes a challenge. They seem to forget about the fact that action and reaction are opposite and equal. In this…

This paper describes a comprehensive review of 31 quasi or experimental research studies from the past decade on the effect of PhET simulations on students' conceptual understanding of physics. Two questions guided the review: (i) To what extent do PhET simulations enhance students' conceptual understanding of physics? (ii) What are the best ways…

This paper tells about the mental model of prospective scholars on the topic of temperature and heat. The purpose of this research is to improve students' mental model by using problem based learning (PBL) model. The number of samples in the study amounted to 72 students with two different classes. The results of the study showed that, (1) the…

A mental model (MM) is an internal representation of students' conceptual understanding. Currently, students have still had difficulties in explaining the physical state of elasticity of solid materials, at submicroscopic level. These difficulties call for this research. Through a mixed method, the study aimed to reveal the development and…

For several decades, scholars have studied the role of cooperation and its outcomes in educational contexts. Yet we lack a complete understanding of how different instructional strategies impact the relationship between cooperation and learning. In this paper we present results from a field experiment with 82 first-year students in an introductory…

Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students' learning about atomic spectra. The TLS has been…

The aim of the research was to know the effect of implementation of problem-based learning model on students' physics achievement and critical thinking. The research was a quasi-experimental using a pre-test-post-test control group design. It was conducted at a state senior high school in Indonesia. The data were collected by a students' physics…

Critical thinking skills are one of the 21st century skills that are effectively trained by using the OR-IPA and Problem Based Learning (PBL) Model, therefore this research aims to compare the effectiveness of both. Research design used True Experiment with Randomized Subject Control-group Pre-test and Post-test with 94 pre-service physics…
