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…

Organic chemistry is a cognitively demanding subject with persistently low student achievement. This review aimed to identify instructional strategies and educational technologies used to improve learning outcomes in organic chemistry across educational levels and learning environments. A systematic review of 40 experimental studies (2014-2023)…

The purpose of this action research study was to explore the impact of problem-based learning on science instruction in my eighth-grade college preparatory classroom. Constructivism was the framework for this study. Problem-based learning is based on constructivist principles, and it served as the instructional model for this study. PBL can foster…

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 study systematically analysed, evaluated and synthesised published studies on 21stcentury skills and science achievement among secondary school students. By scouring 17 well-known online journal databases, 684 related studies were found. After the three-stage screening process, only 17 research papers were included in the study, which were…

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…

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…

Fluorescence spectroscopy experiments are a frequently taught as part of upper-division teaching laboratories. To expose undergraduate students to an applied fluorescence technique, a corrosion detection method, using quenching, was adapted from authentic research for an instrumental analysis laboratory. In the experiment, students acquire…

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…

The objectives of the research were to identify the difficulty level of various types of chemical representation for students and to examine the effects of two different models of teaching and learning chemistry (problem-solving based on multiple representations and problem-solving) on the students' cognitive achievement in chemical equilibrium.…

This study aims to investigate the applicability of context- and problem-based learning (C-PBL) into teaching thermodynamics and to examine its influence on the students' achievements in chemistry, retention of knowledge, students' attitudes, motivation and interest towards chemistry. The embedded mixed method design was utilized with a group of…

In this research; aim was determining student achievement by comparing problem-based learning method with teacher-centered traditional method of teaching 10th grade chemistry lesson mixtures topic. Pretest-posttest control group research design is implemented. Research sample includes; two classes of (total of 48 students) an Anatolian High School…
