The development of students' conceptual understanding and problem solving skills in physics

Abstract

Guided by constructivist and meaningful reception learning theories, this study aimed to develop students' conceptual understanding and problem solving skills in physics from an instruction emphasizing Practical Work Approach (PWA), Explicit Problem Solving Strategy (EPSS), and Cooperative Learning Strategy (CLS).
This study employed Quasi-experimental Design specifically the Pretest-Posttest Control Group Design. Two groups were utilized in this study, the experimental and the control group. The experimental group was exposed to lessons in electric current emphasizing the combined use of PWA, EPSS, and CLS while the control group was exposed to lessons on the same topics using the traditional mode of teaching physics. The dependent variable in this study is the students’ level of conceptual understanding and problem solving skills development in physics. The data were gathered through the use of the pretest and posttest results on Electric Current Conceptual Understanding and Problem Solving Tests, Cooperative Learning Skills Checklist, Questionnaire on Students' Opinions on the Combined used of PWA, EPS, and LS, and Students' Journal.
The research topic was introduced to scientifically and mathematically inclined students of Philippine Science High School – Bicol Region Campus. The class was exposed to lessons on electric current utilizing the three strategies for three weeks during the first grading period.
Based on the analysis of the data gathered, it was found out that the combined use of PWA, EPS, and CLS were effective in improving students' conceptual understanding and problem solving skills in physics.
