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…

Academic performance of students is global issue of great concern to educators. This study sought to ascertain the effect of STEM problem-based learning as an inquiry approach on secondary school student's performance in Biology at government-owned secondary schools in Kebbi State, Nigeria. The non-equivalent control group design was adopted. Two…

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…

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…

This paper illustrates the integration of the hybrid Problem-Based Learning (PBL) approach in the development of the prototype C[superscript 2]HADAM, a multimedia courseware that is intended for the teaching and learning of the Science subject for form two students in Malaysian secondary schools. The discussion begins with the Constructivist…

This study aims to reveal the effectiveness of the problem-based learning (PBL) model in teaching the concepts of heat, temperature and pressure, as well as the effect of the activities on the development of scientific process skills. For this purpose, the change in the academic achievement levels of the students constituting the sampling group…

The aim of this study is to examine the effect of the science module which was designed using the problem-based learning method on the basis of the Integrated Curriculum Model and applied in the blended learning environment on the scientific reasoning and scientific process skills of gifted students. The study was carried out with 9 gifted 5th…

This 2-group quasi-experimental study was conducted to explore the following research questions: Do the fourth graders' post-intervention scores achieved in the unit of force and motion achievement test and attitude scale toward the unit depend on being in the groups that were taught the unit either with 'Online Advance Organizer Concept Teaching…

This research investigated the effect of problem-based learning (PBL) for the topic of "energy metabolism" in a biochemistry course on the academic achievements of students studying in the healthcare field in a nursing department. The study had a one-group pre-test and post-test research design. The study group consisted of first-year…

Purpose: This research aimed to examine the usefulness of a microbiology digital handout as a teaching material validated by experimental research in the improvement of science process skills and cognitive learning outcome of students. Methodology: The study comprises two methods: experimental research and development research. The experimental…

Preparing students for the real challenges in life is one of the most important goals in education. Constructivism is an approach that uses real-life experiences to construct knowledge. Problem-Based Learning (PBL), for almost five decades now, has been the most innovative constructivist pedagogy used worldwide. However, with the rising…

A physiology laboratory course plays an important role in improving the scientific abilities of medical students. This study involved a teaching reform based on problem-based self-designed experiments in a physiology laboratory course. The study subjects were divided into two groups, i.e., students enrolled in 2019 were assigned to the traditional…

The purpose of this descriptive case study was to develop pre-service chemistry teachers' Technological Pedagogical Science Knowledge (TPASK) through novel computational chemistry modules. The study consisted of two phases starting with designing a computational chemistry based learning environment followed by a case study where students'…

This paper uses data from 10 at-scale field experiments in four countries to estimate the effect of inquiry- and problem-based pedagogy (IPP) on students' mathematics and science test scores. IPP creates active problem-solving opportunities in settings that provide meaning to the child. Students learn by collaboratively solving real-life problems,…

The aim of this study was to determine the relationship between students' metacognitive learning, critical thinking, scientific process skills, and academic achievements after the "Cell and Divisions" and "Force and Energy" units which have been processed according to different teaching methods. Furthermore, in this study, it…
