Effectiveness, Triple Kit Package, English Proficiency


The study aimed to (1) evaluate the effectiveness of the triple kit intervention in enhancing the English competence of Grade 9 students, (2) examine the English competence of Grade 9 students with designed tests, and (3) compare the English competence of Grade 9 students by analyzing the results of pretests and posttests. The study was conducted during the first semester of the 2023 academic year. The participants were Grade 9 students from Watcharachai Municipality School, located in Phetchabun Province. A random sample of
39 participants was carefully chosen based on specific criteria, including collaborative skills and motivation to learn. Data were collected using tests and a triple kit intervention. Data were analyzed using basic statistical procedures. This included frequency (f), percentage (%),
mean ( ), standard deviation (S.D.), and hypothesis testing for paired samples using a t-test. The analysis revealed that the intervention (E1 process) achieved an efficiency of 83.42%
and an efficiency of 80.06 (E2 result). This indicated that the intervention was successful in achieving its objectives to a large extent.Scores on the posttest also demonstrated improvement, with scores ranging from 28 to 36 out of a possible maximum of 40. Importantly, the overall posttest score of the 39 participants was statistically significantly higher than their pretest score. This difference was confirmed by a t-test, which yielded a
t-value of 12.384 and a p-value of less than 0.05 (p .000).
