DEVELOPING A PHONICS-BASED INSTRUCTIONAL ACTIVITY PACKAGE TO ENHANCE THAI READING AND WRITING PROFICIENCY AMONG GRADE 3 STUDENTS

Abstract

This study aimed to 1) develop a phonics-based instructional activity package to enhance Thai reading and writing abilities of Grade 3 students, 2) examine its effectiveness based on the 80/80 criterion, 3) compare students’ reading and writing abilities before and after learning through the package, and 4) investigate students’ satisfaction with the learning activities. The participants were 19 Grade 3 students from Ban Nong Rawiang School, Maha Sarakham Province, in the first semester of the 2024 academic year. Research instruments included 12 phonics-based instructional activity sets and 12-hour lesson plans, a 40-item achievement test, and a student satisfaction questionnaire. Data were analyzed using percentages, means, standard deviations, and a dependent-sample t-test.

The research findings were as follows: 1) Twelve phonics-based instructional activity sets were developed in accordance with the sequential steps of phonics instruction and aligned with the Basic Education Core Curriculum, 2) The package achieved effectiveness scores (E1/E2) of 90.52/85, exceeding the 80/80 criterion, 3) Students' posttest mean score (17.00) was significantly higher than their pretest mean score (11.78) at the .01 level of statistical significance, and 4) Students reported the highest level of satisfaction with the instructional activity package. These findings confirmed that the phonics-based instructional activity package was effective in improving Thai reading and writing abilities and was well accepted by learners.
