DEVELOPMENT OF MATHEMATICS LEARNING ACTIVITIES ON RATIO AND PERCENTAGE BASE ON PROBLEM-BASED LEARNING APPROACH SUPPLEMENTED WITH KWDL TECHNIQUE ON ACHIEVEMENT AND MATHEMATICAL PROBLEM SOLVING OF PRATHOMSUKSA 6 STUDENTS

Abstract

The purposes of this research were to 1) develop learning activities on ratio and percentage using problem-based learning approach supplemented with KWDL technique of Prathomsuksa 6 students, 2) study and compare the students' mathematical achievement before and after being taught by learning activities through problem-based learning approach supplemented by KWDL technique, and 3) examine mathematics problem-solving ability of Prathomsuksa 6 students by learning activities using problem-based learning approach supplemented by KWDL technique. The target groups consisted of Prathomsuksa 6 students. The research instruments were divided into 3 parts: 1) 12 lesson plans on ratio and percentage, 2) students' behavior observation forms used by the teacher and research assistant, as well as thr interview questions administrated by the teacher and research assistant at the end of the practice cycle as the students' practice reflection, and 3) test measuring students' mathematics problem-solving ability and students' mathematics achievement. This research was divided into 3 action cycles, organizing learning activities according to learning management plans 1 – 4, 5 - 8, 9 -12. The results of this study were shown as follows: 1) the developed learning activities on ratio and percentage using the problem-based learning approach supplemented with KWDL technique enhanced students’ mathematical problem-solving ability and learning achievement 2) the students' ability on mathematics achievement after being taught by mathematics learning activities on ratio and percentage using problem-based learning approach supplemented by KWDL technique were 11.86 (39.53%) and 24.14 (87.13%) respectively. Students achieved an average post-test score of not less than 75%, and the average score after learning was higher than before learning, and 3) students demonstrated ability on mathematics problems solving after being taught by mathematics learning activities on ratio and percentage using problem-based learning approach supplemented by KWDL technique. The mean score after learning was 27.79 (92.63%), with all students achieving scores of less than 75%.
