IMPROVING THE ABILITY TO UNDERSTAND AND SOLVE MIXED AUTOMATION OPERATIONS THROUGH LEARNING MODELS STUDENT TEAMS-ACHIEVEMENT DIVISIONS (STAD) FOR CLASS VI PRIMARY SCHOOL STUDENTS

This research aims to increase motivation and learning outcomes in Mathematics through the Student Teams Achievement Divisions (STAD) learning model. This type of research is classroom action research carried out in two cycles with mixed arithmetic operations as the material. The subjects of this research were class VI students at SD Negeri 1 Talagening, Bobotsari, Purbalingga, Central Java, totaling 24 students in the 2022–2023 academic year. This research was carried out in 2 cycles, each consisting of 2 meetings and each meeting included the planning, implementation, observation and reflection stages. The action hypothesis in this research is that the use of the STAD-type learning model increases motivation and Mathematics learning outcomes. An indicator of success is when student activity in the learning process reaches a score of 75% or more. The average class score for each cycle is at least 75. Students who achieve a score of 75 or  80% of the total number of students. Based on the results of observations of students, it was 37.50% in cycle I, meeting 1 and 58.33% in meeting 2. Meanwhile, in cycle II, meeting 1, the score was 70.83% and in meeting 2, the score was 83.33%. The number of students who obtained a score of 75 or more in cycle I was 16 students or 66.67%, while in cycle II there were 21 students or 87.50%. In cycle II and the final results it was found that students had exceeded the specified success indicators.
