DEVELOPMENT OF MATHEMATICAL PROBLEM SOLVING ABILITY AND LEARNING ACHIEVEMENT IN LOGARITHM FUNCTION OF MATHAYOMSUKSA FOUR STUDENTS BY ORGANIZING LEARNING ACTIVITIES BASED ON DAPIC

Abstract

          This research is the action research. The proposes of this study were 1) to develop the mathematical problem solving ability of Mathayomsuksa 4 students by organizing learning activities based on DAPIC to achieve the criteria 70 percent, and 2) to study the students’ learning achievement. The target group is 24 students of Mathayomsuksa 4 students in the academic year 2019 from Sarakhampittayakhom School, Muang, Mahasarakham. They were selected by using the purposive sampling of 1 classroom. The research instruments were: 1) 9 lesson plans of the organizing learning activities based on DAPIC, 2) There are 3 sets of the mathematical problem solving ability test, and 3) Learning achievement in logarithm function test. The statistical techniques are applied to analyses the data such as mean, percentage and standard deviation. The results were as follows 1) the mathematical problem solving ability of Mathayomsuksa 4 students by organizing learning activities based on DAPIC. The average for the first, second, third groups are 70.56, 70.00, 86.81 percent, respectively. Especially, for the third group, each of student’s score is higher than 70 percent. Moreover, the mathematical skills have improved for every group, and 2) The students’ learning achievement after organizing learning activities based on DAPIC, students have an average of 11.13 from full score of 15 and a standard deviation of 1.94, representing 70 percent, which is in good level.
