The OrDeP2E learning model (Problem Orientation, Problem Definition, Hypothesis Submission, Hypothesis Testing, and Evaluation) is a natural science learning model that refers to a scientific approach to train the students' natural science problem-solving skills. The purpose of this study is to analyse the effectiveness of OrDeP2E model to change the problem-solving skills of primary school students. This study used one group pre-test and post-test design toward the primary school students of 2017/2018 academic year. The students' problem-solving skills were measured by using the Natural Science Problem-solving Skills Assessment Sheet (NSPSSAS) and Student Response Questionnaire. The indicators of natural science problem-solving skills include identifying problems, formulating problems, making hypothesis, conducting experiment, and drawing conclusions. The data analysis technique used Paired test, n-gain, and Independent test. The result of the research proves that: 1) There is an improvement on the primary school students' natural science problem-solving skills on = 5%; 2) The average n-gain score of students' natural science problem-solving skills were in high category; 3) there is no significant difference (consistent) n-gain on students' natural science problem-solving skills in all groups; and 4) Students responded very positively. Therefore, the OrDeP2E learning model has proven to be effective to solve the natural science problem-solving skills of primary school students. © Published under licence by IOP Publishing Ltd.
