Abstract

This study aims to implement the STAD learning model to improve student learning outcomes and student responses. The STAD model was applied to 29 Semen Gresik Junior High School students. The research design used was one group pretest-posttest design with data collection methods using a test, questionnaire, and observation methods. The research instruments were learning sheets, pretest questions, and student response questionnaire sheets. The study found an increase in learning outcomes through the calculation of N-Gain with an average value of 0.85 in the high category. Student responses in learning activities using the STAD method showed very positive results, with an average percentage of 92%. The application of the STAD learning method was very good at meetings I and II. Based on the research data analysis, it can be concluded that there is an increase in learning outcomes through the STAD type cooperative learning model in the material of the human digestive system.

Abstract

This research aimed to describe the effectiveness of concept mapping in improving student cognitive learning outcomes in material classification materials and their changes implemented in the public Junior High Schools in Surabaya, Indonesia. The research design used one group pretest-posttest. This research involved 16 students from class VII. This research's data collection methods included observation, test, and questionnaire. The results showed that the implementation of learning got 88.15% and 97.36%, with excellent categories at the first and second meetings. The average N-Gain for all students is 0.5 in the medium category. The students' responses to learning got excellent results. Concept mapping with a cooperative learning type Student Teams Achievement Division STAD can improve student cognitive learning outcomes on classification materials and their changes.
