Abstract:
This research aimed to: (1) develop a cooperative learning lesson plan (Co-op Co-op) that meets the 80/80 efficiency criterion, (2) compare learning achievement in reading skills through Co-op Co-op learning activities, and (3) study students' satisfaction with the implementation of Co-op Co-op learning activities. The sample consisted of 32 Grade 7 students at Na Ngio Witthayasat School during the second semester of the 2024 academic year. The research instruments included: (1) the lesson plan for developing reading skills through Co-op Co-op activities, (2) a reading achievement test, and (3) a student satisfaction questionnaire. Data were analyzed using basic statistics: mean, standard deviation (S.D.), and dependent t-test.
The research results were as follows:
1. The lesson plan for developing reading skills through Co-op Co-op activities for Grade 7 students at Na Ngio Witthayasat School achieved an efficiency of 84.02/84.90, which was higher than the set criterion of 80/80.
2. Students post-test scores were significantly higher than their pre-test scores at the .05 level, supporting the research hypothesis.
3. The overall satisfaction of Grade 7 students toward the reading skill development through Co-op Co-op activities was at the highest level, with a mean score of 4.79.
