An Application of the Cooperative Learning Model with Guided Discovery Approach Improves Student Learning Outcomes in an Educational Statistics Course

This study aims to determine the effectiveness of the application of the Cooperative Learning model with a guided discovery approach in improving student learning outcomes in the Statistics of Education course. The research used a quantitative approach with the type of Classroom Action Research (PTK) conducted in two cycles. The research subjects were fourth-semester students of the Pamulang University Economic Education Study Program in the 2024/2025 academic year. Data were collected through learning outcomes tests, student activity observations, and student response questionnaires to the learning model. The results showed that there was a significant increase in the average value of student learning outcomes, from 69.88 in the pre-cycle to 72.76 in cycle I, and increased to 81.26 in cycle II. The percentage of learning completeness increased from 52% to 86% at the end of cycle II. Observations also showed an increase in student activeness and collaboration in the learning process with the percentage of learning implementation reaching 94%. Most students gave a positive response to the use of the Cooperative Learning model with a guided discovery approach because it was considered to encourage active participation and better understanding of the material. Therefore, it can be concluded that the Cooperative Learning model with a guided discovery approach is effectively used in learning Statistics Education to improve learning outcomes and student involvement.
