Students' Performance and Satisfaction with STAD Technique Integrated with OBEM in Basic Mathematics

Abstract

The use of the STAD technique in combination with an Outcome-based Education Module (OBEM) is a collaborative teaching approach that groups students according to their achievement levels and emphasizes student outcomes. The purpose of this study was to analyze students’ learning outcomes before and after using the STAD technique integrated with OBEM in mathematics. The sample consisted of 18 second year students of King Mongkut’s University of Technology Thonburi, Ratchaburi Learning Park in the first semester, of the academic year 2023. The research instruments were the lesson plans using the STAD technique integrated with OBEM, the achievement test, and the student satisfaction questionnaire. Descriptive statistics were used to summarize the means and standard deviations, while inferential statistics, specifically t-tests, were used to compare the achievement tests before and after use. The results showed a significant improvement in students' mean test scores after taking the post-test with a statistical significance level of .05, and more than 60% of students met the stated assessment criteria after completing the post-test with a statistical significance level of .05. Satisfaction ratings showed high to very high levels of satisfaction with this teaching approach, especially in the areas of assessment and teacher quality. These provide convincing evidence of the effectiveness of using the STAD technique integrated with OBEM in mathematics education.
