An Action Research for Developing The Learning Activities by Problem - Based Learning Supplemented with KWDL Technique to Promote Learning Achievement and Mathematical Problem - Solving Ability of Mathayomsuksa 1 Students

Abstract

          The objectives of this research were to 1) develop mathematics learning activities on linear equations in one variable using the problem as a base, supplemented with the KWDL technique for Mathayomsuksa 1 students, 2) compare students' achievement in mathematics before and after the intervention, 3) compare students' mathematical problem-solving ability before and after the intervention. The participants in this research were Mathayomsuksa 1 students totaling 12 students selected by purposive sampling. The instruments used were lesson plans on equations in one variable, a form for recording the results of lesson plans, interview form for students, teacher’s behavior and students' behavior observation forms, the tests that used at the end of the practice cycle, the test form of mathematics achievement and the test form of mathematical problem-solving ability. This research is action research divided into 3 cycles. The data were analyzed by using the statics method including mean, percent and standard deviation.

       The results showed that 1) the development of mathematics learning activities on linear equations in one variable using problem-based learning supplemented with the KWDL technique could develop students’ mathematical problem-solving ability and improve student’s achievement in mathematics 2) Students had achievement test results on mathematics; the pretest mean score was 6.75 or 33.75 percent, and the posttest mean score was 17.30 or 82.92 percent. The posttest mean score was not less than 75 percent and the post-test mean score was higher than the pre-test one. 3) Students had mathematical problem-solving ability; the pretest mean score was 25.58 or 51.17 percent, and the posttest mean score was 40.92 or 81.83 percent. The post-test mean score was not less than 75 percent and the posttest mean score was higher than the pretest one.
