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…

This book represents a crop of wide-ranging research conducted by renown scholars in sub-Sahara Africa revolving around mathematics teaching and professional development programs for mathematics teachers. The research-based proposals and actual how-to-conduct professional development initiatives that enhance effective mathematics instruction are…

This article explores teachers' experiences of implementing the problem-solving approach; a learner centred pedagogic innovation prescribed by a centrally mandated curriculum in Uganda. It presents teachers' interpretations of the pedagogic principles suggested by the innovation as well as their accounts of challenges of implementing the pedagogic…
