The effect of optimization learning resource based on Planning, Organizing, Actuating, Controlling (POAC) on contextual learning to students' conceptual understanding of motion and force material

The research purpose is to improve the students' concepts understanding of motion and force material through the optimization of learning resource based on planning, organizing, actuating and controlling (POAC) on conceptual learning. The researcher used quasi-experimental with the non-equivalent control group. The sampling technique was saturated sampling which used the population as a sample. The research sample was 40 students in Mathematics Education. The experimental group was taught the contextual learning with optimization learning resource based on POAC. The control group was taught the contextual learning without optimization learning resource based on POAC. The collecting data technique used observation, test, questionnaire, and documentation. The researcher used a t-test with independent sample test to compare the average of learning outcomes between the control and experimental group. The research results were: (1) there was an effect of optimization learning resource based on POAC to students' understanding concept that was showed by the significant value 0.00<0.05, (2) the average of learning outcomes of the experimental group was higher than the control group, (3) the average of the experimental group's N-gain was 0.540 (medium category) which was higher than the control group was 0.274 (low category), (4) the learning resource based on planning, organizing, actuating, controlling (POAC) helped the students to be more active in optimizing some structured, qualified, and functional learning resource on motion and force material.
