Abstract

The Teacher-centered learning results in students for being less active in responding to the teacher explanations. Therefore, there is a need for efforts to improve students learning activities. This study aims to improve mathematics learning activities using student teams achievement division (STAD) type of cooperative learning. This research was included in the classroom action research consisting of two cycles. The settings in this study were the students of class VII C in the second semester SMP Negeri 1 Imogiri Bantul in the academic year of 2018/2019, with 32 students consisting of 12 male students and 20 female atudents. The research used observation and interviews as the data collection method. The research instrument used in the form of an observation sheet and interview guidelines. The test of the research instrument is the validity test. The researcher used descriptive and qualitative methods to analyzed the datas. The results showed that using using student teams achievement division (STAD) type of cooperative learning model could improve mathematics learning activities of students of class VII C in the second semester of SMP Negeri 1 Imogiri Bantul in thr academic year of 2018/2019. This is evident from the results of observation of mathematics learning activities of student who experience an increase in earch cycle. In the first cycle the percentage of students mathematics learning activities was 40.95% with sufficient criteria. In the second cycle the percentage of students mathematics learning activities was 79.427% with good criteria.

Abstract

Student learning activities in mathematics are still not good. This is indicated by the small number of students who are actively involved in the learning process, for example, when the teacher asks questions. This study aims to improve mathematics learning activities using cooperative learning models Think Pair Share in classVIIstudents of State Junor High School (SMPNegeri) 1 Imogiri Bantul 2018/2019 academic year. This study is a classroom action research conducted in even semester of class VII B. This research is conducted in two cycles, where each cycle consists of action planning, implementation, observation, and reflection. Data collection techniques are in the form of observations, interviews, and field notes. The research instruments used are observation sheets, interview guidelines, and field notes. While the research instrument test conducted is the validity test. The data analysis technique uses a descriptive qualitative technique.  The results showed that Think Pair Share's cooperative learning model could improve students' mathematics learning activities in class VII B in SMP Negeri 1 Imogiri Bantul. This is evidenced by the results of the observation sheet in each cycle that increased significantly. The average percentage of student activities in cycle 1 is 57,48% with satisfactory criteria. After that, the percentage in the second cycle increased to around 74,92%, indicating good criteria.

Abstract

Lack of understanding of students' mathematical concepts in restating a concept, classifying objects according to specific properties according to the concept, giving examples and not examples of a concept, presenting concepts in various forms of mathematical representation, developing the necessary and sufficient conditions of a concept, and applying the concept or logarithm of problem-solving is a problem that is often encountered in students. This study aims to improve the understanding of the concept of the Pythagorean theorem of class VIII D even semester in SMP Negeri 1 Pleret, Bantul Regency. This type of research is Classroom Action Research (CAR). The research setting was class VIII D in the even semester of SMP Negeri 1 Pleret, Bantul Regency in the academic year 2019/2020, with 31 students.
