The Development of the Problem-Solving Ability for Mathayomsuksa 5 Students Using the Deductive Teaching Method with Heller and Heller's Logical Problem-Solving Strategy

Abstract

Three purposes of this research were 1) to compare the physics problem-solving ability of grade 11 student’s before and after the learning based on the deductive teaching method with Heller and Heller’s logical problem-solving strategy in the overall and step by steps, 2) to compare the physics problem-solving ability of grade 11 student’s based on the deductive teaching method with Heller and Heller’s logical problem-solving strategy after the learning with the 70 percent criterion, and 3) to compare the physics learning achievement of grade 11 student’s based on the deductive teaching method with Heller and Heller’s logical problem-solving strategy after the learning with the 70 percent criterion. The 37 sample from cluster random sampling technique were grade 11th students, in the first semester of the academic year 2023, science and mathematics program, from Watsratong municipal school, Roi-et province. The research instruments used for the study were the lesson plans, physics problem-solving ability test, and physics learning achievement test. Data were analyzed by mean, standard deviation, percentage, and tested the hypotheses with dependent samples t-test, and one sample t-test.
The research results were found that: 1. Physics problem-solving ability of grade 11 student’s who received the deductive teaching method with Heller and Heller’s logical problem-solving strategy in the overall and step by steps after the learning was higher than before the learning at the statistical significance at the .05 level. 2. Physics problem-solving ability of grade 11 student’s who received the deductive teaching method with Heller and Heller’s logical problem-solving strategy after the learning in the overall, Describe the Physics, and Execute the Plan was higher than the 70 percent criterion at the statistical significance at the .05 level. 3. Physics Learning Achievement of grade 11 student’s who received the deductive teaching method with Heller and Heller’s logical problem-solving strategy after the learning was higher than the 70 percent criterion at the statistical significance at the .05 level.
