The Development of KWDL Learning Management for Enhancing Math for 2nd Grade Students

Abstract

Background and Aims: The Basic Education Core Curriculum B.E. 2551 aims to develop learners to be virtuous, intelligent, and happy individuals with the potential for further education and future careers. It sets learning standards across eight core subject areas. In particular, mathematics education focuses on equipping students with knowledge, skills, and mathematical processes necessary for problem-solving, daily life, and continued learning. It also promotes positive attitudes toward mathematics and encourages systematic and creative thinking. The mathematics curriculum is designed to foster students’ abilities in calculation and applying mathematical knowledge as a tool for understanding various subjects and leading a quality life. This study aimed to: 1)examine the effectiveness of the KWDL instructional technique in enhancing mathematics learning achievement in mixed operations—addition, subtraction, multiplication, and division—among Grade 2 students, based on the 75/75 efficiency criterion 2) compare students’ mathematics learning achievement before and after using the KWDL instructional technique, and 3) investigate students’ satisfaction with the KWDL instructional approach.

Methodology: The sample group consisted of 16 Grade 2 students in Kham Riang Khiab Non Sabaeng Don Man School, MahaSarakham Province, during the second semester of the 2024 academic year. The sample was obtained using the cluster random sampling method. The research instruments included 1) Mathematics lesson plans using the KWDL instructional technique, 2) mathematics achievement test, and 3) student satisfaction questionnaire. The statistics used for data analysis were mean, standard deviation, percentage, and dependent t-test.

Results: 1) The KWDL instructional technique in mathematics on mixed operations (addition, subtraction, multiplication, and division) for Grade 2 students showed an efficiency of 80.63/82.81, which was higher than the predetermined criterion. 2) Students who received instruction through the KWDL technique demonstrated significantly higher post-test academic achievement compared to the pre-test, at the .05 level of statistical significance. 3) Students' overall satisfaction with learning through the KWDL technique was at a high level

Conclusion: The development of the KWDL instructional technique effectively enhances mathematics learning achievement among Grade 2 students. This is because the learning activities help students improve their problem-solving abilities in mathematics by encouraging active participation in the learning process through questioning, exploration, and self-reflection. These practices promote analytical thinking and systematic problem-solving skills, resulting in better understanding of the content and improved academic achievement.
