The learning approach with the STAD type cooperative learning model (Student Teams Achievement Divisions) is a learning concept that helps teachers relate the material being taught to students' real-world situations and encourages students to make connections between their knowledge and its application in their lives as family and community members. With this concept, learning outcomes are expected to be more meaningful for students. The learning process takes place naturally in the form of student activities working and experiencing, not transferring knowledge from teacher to student. A learning strategy is far more important than a result.
