DEVELOPMENT OF MATHEMATICS ABILITIES SKILLS OF PRIMARY SCHOOL STUDENTS GRADE 4 BY USING THE OPEN APPROACH AND COOPERATIVE LEARNING STAD TECHNIQUES

Abstract

The objectives of this research were 1) to develop 4th grade students’ mathematical reasoning abilities through the Open Approach Learning Management and STAD Technique so that they made a mean achievement score of 70% and that at least 70% of them passed the 70% criterion and 2) to develop the students’ learning achievement through the Open Approach Learning Management and STAD Technique so that they made a mean learning achievement score of 70% and that at least 70% of them passed the 70% criterion.  The sample group consisted of twelve 4th grade students at Ban Kudkwangprachasan School, under Khon Kaen Primary Education Office Area 1, who were selected through the purposive sampling during the second semester of the 2021 academic year.  The One-Shot Case Study Design was applied for the study.  Research instruments included 1) 10 lesson plans based on the Open Approach and STUD Technique which took 10 instructional periods to finish, 2) a 10-item essay test on addition, subtraction, multiplication and division and 3) a learning achievement multiple-choice test consisting of 30 items on addition, subtraction, multiplication and division.  The basic statistics of arithmetic mean, percentage and standard deviation were applied for data analysis.  The findings show that: 1) The students made a mean achievement score of 25 marks or 83.33% of the full marks, and 12 students or 100% of the group passed the prescribed criterion, 2) The students made a mean learning achievement score of 24.42 or 81.40% of the full marks, and 11 students or 91.67% of the group passed the 70% criterion which is higher than the prescribed criterion.
