Abstract

This research is an experimental research, with the aim to find out: (1) how the students' mathematical problem solving ability before the application of the Power of Two method; (2) how is the students' mathematical problem solving ability after the application of the Power of Two method; (3) whether the Power of Two method is effective on students' mathematical problem solving abilities. The population in this study were all students of class XI MA Attarbiah Islamiah Kolaka in the 2020-2021 school year which consisted of 1 class with a total of 30 students. Sampling is done by using a census or total sampling. Sampling is done by using all the population. The analysis used is descriptive analysis and inferential analysis. Furthermore, the results are based on hypothesis testing: a statistical t-test (one sample t-test) was performed. It was obtained that tcount = -8.53 with ttable = -1.67. Accept H0 if -1.67≤ tcount≤ 1.67 because tcount = -8.53 is outside the H0 acceptance interval, then H0 is rejected and H1 is accepted. Thus there is a significant difference between students' mathematical problem solving ability scores before using the Power of Two method and after using the Power of Two method.

Abstract

This research aims to improve mathematics learning outcomes of students of grade VII1 SMP Negeri 15 Kendari on set material through the application of the Student Teams Achievement Division (STAD) learning model. This type of research is Classroom Action Research (CAR). This research was conducted in class VII1 students of SMP Negeri 15 Kendari with 24 students. The results of this study indicate that the completeness of student learning outcomes in the first cycle reached 70.83%, in the second cycle reached 79.16%, and in the third cycle reached 83.3%. In terms of process, the Student Teams Achievement Division (STAD) cooperative learning model has been implemented in accordance with the learning scenario in class VII1 of SMP Negeri 15 Kendari with an average of 75% in cycle I, 85% in cycle II and 95% in cycle III. Based on the performance indicators, it was concluded that student learning outcomes in the material set of students in class VII1 of SMP Negeri 15 Kendari could be improved through the cooperative learning model of Student Teams Achievement Division (STAD).
