The effectiveness of PO2E2W learning model on natural science learning to improve problem solving skills of primary school students

Abstract

The PO2E2W learning model (problem oriented, observation, explanation, orientation, and write in science) is a self-regulated learning-oriented learning model that is designed to improve problem-solving skills. The purpose of this study is to analyse the effectiveness of PO2E2W learning model on natural science learning to change the problemsolving skills of primary school students. This research used one group pre-test and post-test design in fourth grade students of academic year 2017/2018. Students' problem-solving skills were measured by using Problem-Solving Skills Assessment Sheet (PSSAS) and Student Response Questionnaire. The indicators of problem-solving skills include representing the problems, developing solutions, justifying proposed solutions, and evaluating the solutions. The data analysis technique used Paired test, n-gain, and Independent test. The results of the study prove that: (1) There is an increase in problem-solving skills of primary school students at α = 5%; (2) The average score of n-gain of the students' problem-solving skill was in medium category; (3) There is no significant (consistent) difference on the natural science problem-solving skills in all groups, and (4) Students responded very positively. Therefore, the learning model of PO2E2W on natural science learning has proven to be effective to improve the problem-solving skill of primary school students.
