A Study of Mathematical Problem Solving Ability Using the KWDL Technique for Mathayomsuksa 2 Students on the Subject of Pythagorean Theorem

Abstract

         This research aimed to improve the abilities of Mathayomsuksa 2 students to solve mathematical problems based on the Pythagorean theorem by using the KWDL technique. The sample used in this research were Mathayomsuksa 2/2 students at Sahatsakhan Suksa School, under the Office of Kalasin Secondary Educational Service Area, semester 1, academic year 2022, totaling 34 students obtained by cluster random sampling. The tools used in the research consisted of: 1) A learning plan for solving mathematical problems by using the KWDL technique on the Pythagorean Theorem, 10 hours 2) The mathematical problem-solving ability test consisted of five items. Statistics used in data analysis were mean standard deviation and percentage. The research results were as follows: Students were able to solve mathematical problems based on the Pythagorean theorem. By learning management with the KWDL technique, the number of passing scores was 70 percent, representing 86.54 percent of the full score, and there were 34 students passing the criteria of 70 percent, representing 100 percent of all students.
