Using of student teams achievement divisions model (STAD) to improve student's mathematical learning outcomes

The purpose of this study was to improve the mathematics learning outcomes of fifth-grade students through the application of the Student Teams Achievement Divisions (STAD) learning model. The research method used a classroom action research using Kemmis and Taggart model consisting of three cycles through stages consisting of planning, implementation, observation, and reflection. Data were collected using interview, observation, and learning outcome tests. The study was conducted on 32 students by assessing teacher activity, student activity, and learning outcomes. The score of minimum mastery learning (KKM) is 80. Data analysis using qualitative analysis. The results of the pre-cycle study stated that ten students (31.25%) managed to achieve learning outcomes above the KKM. The first cycle reported that there were 20 students (62.5%) completing scores above KKM, and cycle II as many as 28 students (87.5%) achieved scores above KKM. The study states that the STAD model can be used as a fun learning model and a solution in solving the difficult problem of students understanding the fifth-grade elementary school mathematics material.
