The Development Of Learning Model (Pelac) To Promote The Problem Solving Ability On Physics 1 For Graed 10

Abstract

The purposes of this research were 1) to study the effect of using the PELAC model in learning to promote the ability to solve problems in physics 1 of Grade 10, 2) to study the achievement in physics 1 of Grade 10 by the PELAC model, compared with the school's target criteria of 70 percent of the full score. This research used a Research & Development process (R&D) with the Pretest-Posttest Control Group Design.

The research results were found that the PELAC model promoted problem solving ability in Physics consistent in all components and was suitable for Mathayomsuksa 4 students. In conclusion, the PELAC model has increased the learning achievement of Physics 1 of Grade 10. 26 out of 30 students (86.67 percent) scored more than 70 percent of the full score.
