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…

Eminent scientists, like Einstein, worked with theoretical contradiction, thought experiments, mental models and visualisation--all characteristics of children's play. Supporting children's play is a strength of early childhood teachers. Promising research shows a link between imagination in science and imagination in play. A case study of 3…

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…

Information and communication technologies (ICT), namely the Internet, can play a valuable educational role in several school subjects, including science education. The same applies to problem-based learning (PBL), that is, a student-centered active learning methodology that can prepare students for lifelong learning. WebQuests (WQs) combine PBL…

If our chosen aim in science education is to be inclusive and to improve students' learning achievements, then we must identify teaching methodologies that are appropriate for teaching and learning specific knowledge. Karagiorgi and Symeo (2005) remind us that instructional designers are thus challenged to translate the philosophy of…

In this study, the author implemented a problem-based learning (PBL) experience that allowed students in an advanced science methodology course to explore differentiated instruction. Through working systematically in small, collaborative groups, students explored the nature of differentiated instruction. The objective of the study was to examine…

This research study aims to examine the effectiveness of a problem-based learning (PBL) on 9th grade students' understanding of intermolecular forces (dipole-dipole forces, London dispersion forces and hydrogen bonding). The student's alternate conceptions about intermolecular bonding and their beliefs about PBL were also measured. Seventy-eight…

The purpose of the study is to compare problem based learning (PBL) and lecture-based learning (LBL) in Hong Kong secondary students' science achievement. Secondary One students were divided into two groups: group A (n = 37), was taught two topics: "Human Reproduction" and "Density" through PBL; group B (n = 38) was taught the…

The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum with those in a conventional primary science teacher preparation program with regard to success in learning about gases and developing positive attitudes towards chemistry. The subjects of the study were 101 first year…
