Development Science Learning Achievement on Ecosystems and Biodiversity Using STAD Cooperative Learning Technique with Gamification for Grade 9 Students.

Abstract

This research aimed to: 1) develop Grade 9 students' science learning achievement on ecosystems and biodiversity through Student Teams-Achievement Divisions (STAD) cooperative learning combined with gamification; 2) investigate the effects of STAD cooperative learning combined with gamification on the science process skills of Grade 9 students; and 3) examine the effects of STAD cooperative learning combined with gamification on the scientific attitudes of Grade 9 students. The sample consisted of 35 Grade 9 students (Mattayomsuksa 3/6) from Borabue School in Maha Sarakham Province during the 2025 academic year, selected through cluster random sampling. The research instruments included:1) four lesson plans using STAD cooperative learning combined with gamification; 2) a 30-item multiple-choice science achievement test; 3) a 20 - item multiple-choice science process skills test; and 4) a scientific attitude observation form. The statistics utilized for data analysis included percentage, mean, standard deviation, and t-test for dependent sample. The research findings revealed that:1) the post-test science learning achievement was statistically significantly higher than the pre-test score at the .05 level; 2) the students' science process skills passed the 70% criterion, reaching 75.15% with a mean score of 15.03 and a standard deviation of 2.56; and 3) the students' scientific attitude were at a "very good" level, accounting for 99.33% with a mean score of 2.98 and a standard deviation of 0.10.
