Development of Scientific Concept through Using Predict-Observe-Explain (POE) Learning Management with Graphic Organizers Technique of Mathayomsuksa 3 Students

Abstract

The purposes of this research were to 1) to compare scientific concepts before and after learning by using Predict - Observe - Explain (POE) learning management with graphic organizers Technique and 2) to study the development of scientific concepts of students between before and after learning with Predict - Observe - Explain Learning management with graphic organizers technique. Samples were 27 students of Mathayomsuksa 3 students which school located in PathumThani Primary Educational Service Area 2, randomly selected by cluster random sampling. Research tools were 1) lesson plan which focus on Predict - Observe - Explain Learning management with graphic organizers technique and 2) scientific concepts test with reliability at 0.88, difficulty index between 0.26-0.78 and discrimination index between 0.21-0.79. The collected data were analyze by using mean, standard deviation, gain score and t-test for dependence. The research findings were as follow; 1) Students who received the learning management to with Predict - Observe - Explain Learning management with graphic organizers technique had scientific concept after learning greater than before learning with statistical significant level at .05 2) Students who received the learning management to with Predict - Observe - Explain (POE) learning management with graphic organizers technique had scientific concept at a moderate level.
