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 1) to develop learning activities on ratio and percentage using problem-based learning approach supplemented with KWDL technique of Prathomsuksa 6 students, 2) to study and compare the students' mathematical achievement before and after being taught by learning activities through problem-based learning approach supplemented with KWDL technique, and 3) to study mathematics problem solving ability of Prathomsuksa 6 students by learning activities using problem-based learning approach supplemented with KWDL technique. The target groups consisted of Prathomsuksa 6 students. The instruments used in this study were divided into 3 parts: 1) 12 lesson plans on learning activities; activities on ratio and percentage, 2) students' behavior observation forms used by the teacher and research assistant. The interview questions used by the teacher and research assistant at the end of the process. The tests were used at the end of the practice cycle as the students' practice reflection, and 3) the test form of students' ability on mathematics problem solving and students' mathematics achievement. This research was divided into 3 action cycles: Organize learning activities according to learning management plans 1 – 4, 5 - 8, 9 -12 The results of this study were shown as follows: 1) The development of mathematics learning activities on ratio and percentage using problem-based learning approach supplemented with KWDL technique process could develop the ability of mathematical problem solving and mathematics achievement of students. 2) The students' ability on mathematics achievement after being taught by mathematics learning activities on ratio and percentage using problem-based learning approach supplemented with KWDL technique were 11.86 or 39.53 and 24.14 or 87.13 percent respectively. Students had an average score after learning not less than 75 percent 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 with KWDL technique. The mean score after learning was 27.79 or 92.63 percent. Students had an average score after learning not less than 75 percent.
