THE DEVELOPMENT OF A SET OF EXERCISES UTILIZING THE SOUTHERN THAI DIALECT TO ENHANCE MATHAYOM 1 STUDENTS' COMPREHENSION AND READING OF RHYTHM SYMBOLS AT SATRI PHATTHALUNG SCHOOL

Abstract

This research seeks to use the Southern Thai dialect to create a set of exercises to improve skills in reading rhythm symbols. Specifically, it aims to evaluate the effectiveness of the set of exercises and assess students' progress in school before and after learning to improve rhythm and melody reading skills. The purposive sampling method was utilized to select a sample group of 20 Mathayom 1 students from Satri Phatthalung School in the second semester of the 2024 academic year. Then, a one-group pretest-post-test design was employed to determine the effectiveness of the exercise. The research instruments consisted of exercises to enhance rhythm symbol reading skills using Southern Thai dialect words, a pretest and post-test, and a mid-course test. The statistical methods employed were percentages, means, standard deviations, and t-test analysis. The findings indicated that the set of exercises developed to enhance rhythm symbol reading skills using the Southern Thai dialect was effective. In addition, the efficiency ratio (E1/E2) of 90.50/92.25 was higher than the criterion of 80/80. Moreover, there was a significant improvement at the .05 level in the post-test scores of students who used the developed exercises compared to their pretest scores.
