A STUDY OF THE ABILITY TO SOLVE MATHEMATICAL PROBLEMS ON PERCENTAGE BY USING CONTEXT - BASED LEARNING MANAGEMENT WITH KWDL TECHNIQUES OF GRADE 5 STUDENTS

Abstract

The objectives of this research were to 1) to examine the mathematical problem-solving ability of Grade 5 students on the topic of percentages. 2) to compare the mathematical problem-solving ability on the topic of percentages after using context-based learning combined with KWDL techniques against the 70% benchmark among Grade 5 students. and 3) Assess the students’ satisfaction with this learning approach. The sample consisted of  27 Grade 5 students from the Demonstration School of Buriram Rajabhat University, Mueang District, Buriram Province, during the second semester of the 2024 academic year, selected through cluster random sampling The research instruments included: 1) Nine lesson plans developed for the study 2) a subjective test comprising five mathematical problem-solving questions on percentages. and 3) a 17-item questionnaire assessing student satisfaction with the context-based learning combined with the KWDL technique. Data were analyzed using percentage, arithmetic mean, standard deviation, and one-sample t-test.

The results of the study were as follows: 1) Twenty-Three students represent eighty-five point nineteen percent of all students possess the ability to solve mathematical problems in all four areas: understanding the problem, analyzing and planning solutions, executing the solution, and summarizing the answer; 2) the students’ problem-solving abilities in percentages exceeded the 70 % benchmark, with a statistically significant difference at the 0.05 level; and 3) overall, the students’ satisfaction with the context-based learning approach combined with the KWDL technique was at the highest level.
