The Effects of Using Problem-Base Learning on Linear Programming to Mathematical Problem Solving Ability of Mathayomsuksa Six Students

Abstract

This research aims to 1) study the mathematical problem-solving abilities of students in Mathayomsuksa 6 after learning through problem-based learning activities, and 2) explore the instructional approaches using problem-based learning that enhance mathematical problem-solving abilities, specifically focusing on linear programming. The target group for this study consisted of 38 students in Mathayomsuksa 6 from Photisarnpittayakorn School. The research tools included five lesson plans and a test measuring mathematical problem-solving abilities. The research results indicate that: 1) there is an improvement in mathematical problem-solving abilities among students, with 68.42% of the total number of students, and the average test score being 65.92, and 2) the guideline for organizing learning activities using problem-based learning that enhance mathematical problem-solving abilities include: 1) providing real or realistic problem situations, 2) using guiding questions to help students solve problems and construct knowledge on their own, and 3) providing opportunities for students to exchange ideas to improve problem-solving strategies to the highest possible level.
