The development of mathematics problem-solving ability of Mathayomsuksa 5 students through learning management that incorporated problem-solving processes with real-life situations

Abstract

This research aimed to develop the mathematical problem-solving ability through learning management that incorporated problem-solving processes with real-life situations. The target group was 30 students of Mathayomsuksa 5 in the academic year 2023 from School in Roi Et Province. The research methodology is classroom action research, which comprises three cycles. The tools used in this research include 1) a mathematics learning plan which incorporated problem-solving with real-life situations on the topic of sequences and series, 2) mathematical problem-solving ability tests 3) observation form, and 4) interview form. Data were collected in the first semester of the academic year 2023. The data was analyzed by using percentages. The result of this research was as follows: the ability to solve mathematics problems of Mathayomsuksa 5 students after learning about mathematics using learning management that incorporated problem-solving processes with real-life situations including, 1) In the first cycle, there were 14 students whose mathematics problem-solving abilities scored higher than 70 percent of the full score of 30, accounting for 46.67, 2) In the second operational cycle, there were 21 students, accounting for 70 percent of all students, and 3) In the third operational cycle, there were 30 students, representing 100 percent of all students.
