Abstract

PO2E2W model (problem oriented, observation, explanation, elaboration, and write in science) is a learning model which oriented on self regulated learning that is designed to improve problem solving skill. The aim of this research is analyzing the effectiveness of PO2E2W model to improve problem solving skill on elementary school student in science at the year 2017/ 2018. This research is pre-experimental research that uses one group pre-test and post-test design on two groups which every group consists of ten students. Before science learning with PO2E2W model begins, the students is given an problem solving skill (pre-test) and after doing the learning, students is given a same test like before (post-test). The data which has been collected is analyzed by using pairing t-test, n-gain, and two average similarity tests. The result of this research shows that there is an improvement of students problem solving skill at \(\alpha\) = 5% with average n-gain in medium category and there is no differences between two groups. Therefore, the PO2E2W model is effective to to improve problem solving skill on elementary school student.
