DEVELOPMENT OF THE STAD COOPERATIVE LEARNING AND SIMULATION TECHNIQUE SUPPLEMENTED WITH POLYA PROBLEM SOLVING ON MONEY AND INCOME AND EXPENSE ACCOUNT ON MATHEMATICAL PROBLEM SOLVING AND ACHIEVEMENT OF PRATHOMSUKSA 3 STUDENTS

Abstract

The purposes of this research were 1) to develop of the STAD cooperative learning and simulation technique supplemented with POLYA problem solving on money and income and expense account on mathematical problem solving and achievement of Prathomsuksa 3 students 2) to study mathematics problem solving ability and 3) to study and compare the students' mathematics achievement before and after The target groups consisted of 20 Prathomsuksa 3 students at Anuban Nongsang SAO. School, Wapiprathum district, Mahasarakham province who were studying Mathematics in semester 2 of the academic year 2024. The instruments used in this study were 12 lesson plans on learning activities; activities on money and income and expense account. students' behavior observation forms used by the teacher and research assistant. The interview questions were also operated by teacher and assistant teacher at the end of the process. The tests were used at the end of the practice cycle as the students' practice reflection. the test form of students' ability on mathematics problem solving and students' mathematics achievement. This research is an action research. When all operating cycles have been completed, then performed a final test. The results of this study were shown as follows: 1) Development of mathematics learning activities of the STAD cooperative learning and simulation technique supplemented with POLYA problem solving on money and income and expense account All 3 operational cycles provide issues for developing learning management. It can be concluded that there are steps and learning activities organized that are appropriate for students and can develop the ability to solve mathematical problems. There are 6 important steps: Step 1, preparation step, Step 2, presenting new content, Step 3, dividing into groups, Step 4, accepting roles and following roles, Step 5, discussing results, Step 6, evaluating step. 2) Students had ability on mathematics problems solving after being taught by mathematics learning activities of the STAD cooperative learning and simulation technique supplemented with POLYA problem solving. The mean score after learning was 27.05 or 90.17 percent. Students had an average score after learning not less than 75 percent. 3) The students' ability on mathematics achievement after being taught by mathematics learning activities  of the STAD cooperative learning and simulation technique supplemented with POLYA problem solving were 14.90 or 49.67 learning and 28.25 or 94.17 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.
