Abstract

The purpose of this research is to find out how the application of the Arisan Card learning model improve students' mathematics learning achievement. This research is a Classroom Action Research. Subjects of this study were students of class VII-B SMP PGRI 6 Malang. Data collection procedures in this study are tests, observations and field notes. The results of this study are the completeness of students in the activities of the first cycle 60.71% and the second cycle 89.28% and the observation results of the first cycle teacher, observer I 76.06%, observer II 75.21% and second cycle observer I 88.03% observer II 85.47% and for the observations of students I observer I cycle 73.50%, observer II 70.94% and second cycle observer I 85.47%, observer II 84.61%. Based on the results of the study, the Arisan Card learning model?s steps are: 1) dividing students into groups by emphasizing the circular sitting formation; 2) distribute the answer papers to each group; 3) put the questions into arisan bottle and then shaken and poured; 5) asks one of the groups holding the answer paper to move forward and present it to the class; 6) if the answer is correct then the group gets points.

Abstract

This study aims to describe the analysis of student mistakes based on the stages of Newman in solving the Pythagorean theorem material story problems. This type of research is descriptive with a qualitative approach. The subjects of this study were students of class VIII A PGRI 6 SMP Malang, totaling 28 students in the 2018/2019 school year. Data analysis techniques include data reduction, data presentation and conclusion drawing. Meanwhile, checking the validity of the data using the technique of triangulation of sources in the form of in-depth interviews with 3 students of class VIII A selected based on high, medium, and low abilities. The results showed that at the stage of reading subject A5 made a mistake in question number 3. In the understanding stage, an error in problem number 1 was made by subjects A29, A7, A11, and A5, while error number 2 was subject A21, A7, and, which made a mistake in question number 3 namely, A6, A29, A7, and A5. At the transformation stage subjects A5, and A11 made mistakes on questions number 2 and 3. In the process skills stage subjects A5 made mistakes on questions number 2, and subjects A21, A6, A7, A11, and A5 made mistakes on questions number 3. Meanwhile , subjects who make mistakes at the writing stage of the final answer are A29, A7, A11, and A5.
