Abstract

In solving mathematical problems, students must find errors in understanding a material given by the teacher, this can happen due to several factors. In this article it aims to analyze the errors and difficulties experienced by students of class X Phase E.7 in studying the material of root forms. One way that can be done is by identifying the cause of students' mistakes in doing math problems during the mathematics learning process in the classroom. This research uses a qualitative descriptive approach. With research instruments in the form of field observations and student learning outcomes. The research subjects of class X Phase E.7 SMA N 1 HARAU students were 7 students who had the highest final semester exam scores.

Abstract

This study aims to determine the significant effect of self confidence on students' critical thinking skills. The hypothesis in this study is that there is a significant effect of self-confidence on the ability to think critically mathematically.This type of research is correlational. The population in this study were all VIII grade students as many as 6 classes totaling 188 students. The research sample was taken randomly 30 students. The data in this study are in the form of self confidence questionnaire and mathematical critical thinking skills questions. The data analysis technique uses correlation analysis. The results of this study obtained t_0 = 3.391 and t_table = 1.70 at the real level α = 0.05. This shows that t_0> t_table which means H_(0) is rejected or H_1 is accepted which states that there is a significant effect of self confidence on the critical thinking skills of class VIII students. The effect of self-confidence on mathematical critical thinking ability is a moderate relationship with r_(Xy) = 0.54 and obtained a coefficient of determination of 29.16%

Abstract

This research is motivated by the results of observations, where students are not used to solving critical thinking problems, especially PISA questions. This study aims to describe students' critical thinking skills in solving PISA questions. This type of research is a type of quantitative descriptive research. The sample in this study is 30 students of Class IX-F SMP Negeri 1 Bukittinggi. The data collection technique used is a test of critical thinking skills in PISA questions. The collected data is analyzed by the procedure of analyzing the results of the work, presenting the data and drawing conclusions. The results of the data analysis showed that students' critical thinking skills in solving PISA questions in class IX-F SMP Negeri 1 Bukittinggi as a whole were classified in the low category with a percentage of 52.6% and different for each indicator. This can be seen in the completion of students' pisa questions on 4 indicators of critical thinking ability, namely Interpretation is 67% in the high category, for the Analysis, Evaluation and Inference indicators are classified in the low category with 56.44%, 43.83% and 45.16% respectively. So it is concluded that the level of students' critical thinking ability in solving PISA questions in class IX-F SMP Negeri 1 Bukittinggi is classified as low

Abstract

This study was motivated by problems found in Grade VIII of SMP N 1 Sasak Ranah Pasisia, West Pasaman Regency, namely the low self-confidence of students in learning. This could be seen during the teaching and learning process, where only a few students took the initiative to present their work in front of the class. Students’ low mathematics learning outcomes were also evident from their daily test scores. The research problems in this study were: (1) how students’ self-confidence develops during the learning process using the cooperative learning model of the Student Teams Achievement Division (STAD) type, and (2) whether students’ mathematics learning outcomes taught using the STAD cooperative learning model are better than those taught using conventional learning. This research employed a pre-experimental approach with the Static Group Comparison Design. The sample was determined randomly after conducting tests of normality, homogeneity, and equality of means on the population data. The sample consisted of students from class VIII.2 as the experimental group and class VIII.1 as the control group. Students’ self-confidence data were collected through a questionnaire, while learning outcomes were obtained from a test administered to students. Based on the results of the analysis, the percentage of students’ self-confidence was 76.18%, categorized as high. The mathematics learning outcome test was analyzed using the t-test at a significance level of α = 0.05, yielding tcount > ttable (2.96 > 1.67) and P-value = 0.008 < α = 0.05. Therefore, H0 was rejected and H1 was accepted. It can be concluded that students’ mathematics learning outcomes using the STAD cooperative learning model are better than those using conventional learning in Grade VIII of SMP N 1 Sasak Ranah Pasisia, West Pasaman Regency.
