The development of learning achievement in the Physics subject, specifically in the topic of Optics by using the MACRO model in conjunction with the Think-Talk-Write technique for 5th-year high school students. -

Abstract

This study aimed to: (1) develop a learning activity plan using the MACRO Model combined with the Think-Talk-Write technique on the topic of "Light in Physics" for Grade 11 students and evaluate its effectiveness based on the 60/60 criterion; and (2) compare students' learning achievement with the standard criterion of 60% of the total score. The sample consisted of 24 Grade 11 students from Chiang Rai Provincial Administrative Organization School in the 2024 academic year, selected through stratified sampling. The research instruments included: (1) four learning activity plans based on the MACRO Model combined with the Think-Talk-Write technique and (2) a 20-item, four-option multiple-choice achievement test. Data analysis involved calculating the mean, standard deviation, efficiency formula, and t-test. The results indicated that: (1) the developed learning activity plans achieved an efficiency score of 64.58/62.91, surpassing the 60/60 criterion, and (2) students taught using this approach demonstrated significantly higher learning achievement than the 60% standard score at the .05 level of statistical significance.
