Abstract

Abstract

        The purposes of this action research were 1) to develop  learning activities by using open approach supplemented with Polya’s problem solving process for promote problem solving in mathematical ability. 2) to study the results of developing problem solving in mathematical ability of students after organizing learning activities by teacher. The target groups consisted of Prathomsuksa 5 students from a school in Udonthani province who were studying mathematics in academic year of 2022, 7 students in total acquired by purposive sampling. The tools used in the research were classified into three categories: 1) the instruments for collecting data which contained 9 lesson plans for the mathematics course on the volume and capacity of a rectangular shape. 2) tools for reflecting on operational results, namely, a form for recording the results of lesson plans, The Interview questions form for students, an observational form of learning activities behavior of teachers, students’ learning behavior observation form, and tests at the end of the operating cycle. 3) The tools for research evaluation were the test form of students’ problem solving in mathematical ability, which has reliability of 0.79. This research is divided into 3 cycles. Also, reflect on information for improving and developing learning activities. The statistics to analyzed data were mean, percentage, standard deviation and development score.
        The research results were the development of the learning activities by using open approach supplemented with Polya’s problem solving process to promote problem solving in mathematical ability, there are 4 steps these include step 1 posing open-ended problem, step 2 students’ self learning according to Polya’s 4 steps problem solving process consist of 1) understanding the problem 2) devising a plan 3) carrying out the plan and 4) looking back, step 3 whole class discussion and comparison and step 4 summarization through connecting students ideas emerged in the classroom. Students had an average problem solving in mathematical ability score, the value was 79.14, representing 87.94% and the standard deviation was 6.31. All students had scores of problem solving in mathematical ability more than 75 percent.
