Effects of Cooperative Learning with Multimedia on Learning Achievement in Sex Education among Sixth-Grade Students

Abstract

This research aimed to: 1) compare students’ learning achievement before and after implementing cooperative learning integrated with multimedia; and 2) examine students’ satisfaction with cooperative learning integrated with multimedia on the topic of Sex Education. The research was conducted with 10 Grade 6 students at Ban Nong Kung School under the Nakhon Phanom Primary Educational Service Area Office 1 during the second semester of the 2025 academic year. The target group was selected through purposive sampling. The research instruments consisted of: 1) five cooperative learning lesson plans integrated with multimedia, totaling 10 hours of instruction, which were rated as highly appropriate; 2) instructional multimedia, which was rated as highly appropriate; 3) a 30-item, four-option multiple-choice learning achievement test, with an Index of Item-Objective Congruence (IOC) ranging from 0.67 to 1.00, a difficulty index ranging from 0.61 to 0.80, a discrimination index ranging from 0.20 to 0.40, and a reliability coefficient of 0.92; and 4) a 10-item, five-point Likert-scale satisfaction questionnaire, with an IOC ranging from 0.67
to 1.00. The data were analyzed using mean, standard deviation, and the Wilcoxon signed-rank test.

The results revealed that: 1) students who learned through cooperative learning integrated with multimedia on the topic of Sex Education had significantly higher post-test learning achievement scores than their pre-test scores at the .05 level of statistical significance; and 2) students’ overall satisfaction with cooperative learning integrated with multimedia was at the highest level. These findings indicate that cooperative learning integrated with multimedia can effectively enhance students’ learning achievement.
