Abstract

This research is based on a preliminary study conducted by researchers during observations at SMP Negeri 3 Mandrehe Barat. The problem is that students' mathematical problem-solving skills still need improvement. This study aims to determine whether there is an effect of brainstorming learning methods on students' mathematical problem-solving ability. This type of research uses the quasi-experimental research method involving two groups that are given different treatments. The population of this study was all VIII classes of SMP Negeri 3 Mandrehe Barat, and two classes were selected by simple random sampling as research samples, namely class VIII-A totaling 20 students as an experimental class taught using the brainstorming learning method and class VIII-B 21 students as a control class taught using conventional learning methods. Data were collected through student mathematical problem-solving ability tests. Based on this research, the results of hypothesis testing are   and . Because   > , then Ho is rejected, and Ha is accepted that there is an effect of brainstorming learning method on students' mathematical problem-solving ability at SMP Negeri 3 Mandrehe Barat.

Abstract

This study was motivated by the lack of self-confidence, fear, worry, discomfort, and nervousness of students during the mathematics learning process and the low mathematical communication skills of students. This study aims to determine the effect of self-efficacy and mathematical anxiety on students' mathematical communication skills. This type of research is correlational research with quantitative methods. The research instrumental used are self-efficacy questionnaire, mathematical anxiety questionnaire and mathematical communication ability test. The population in this study amounted to 43 people with a sample size of 39 people taken using probability sampling with simple random sampling technique. The data analysis used is multiple linear regression. Based on the results of the study, obtained in the First hypothesis the value of tcount(3.9116) >ttabel (0.0631) with H0 rejected and Ha accepted which if students' self-efficacy is higher then students' mathematical communication skills are also higher and vice versa. In the second hypothesis, the value of tcount(0.2819)>ttabel (0.0631), with H0 rejected and Ha accepted which if students' math anxiety is high then their math communication skills are low and vice versa. Concluded that the two independent variables together have a significant influence on the dependent variable with a percentage of 32.45%.
