Abstract

In the learning process, only a few students were involved in learning, others preferred to remain silent. When given the opportunity to work on questions in front of the class, only those students were brave. In the learning process, students' mathematical communication skills are also seen. Knowledge: When students are given story questions, students are not able to find the information contained in the questions, students have difficulty understanding the information presented in pictures or graphs. This makes students experience difficulty in solving questions. For this reason, this research aims to explain and determine students' mathematical communication abilities (KKM) based on students' self-confidence in class XII statistics material. This research will describe the KKM of students with high, medium and low self-confidence. The research method used in this research is qualitative descriptive research. The research subjects were 9 students of class XII MIPA A SMAN 1 Ngabang. Research subjects were selected based on the results of a self-confidence questionnaire that had been filled out by students. Data collection uses questionnaires to collect data on self-confidence, test questions and interviews to collect data on mathematical communication skills. The data analysis techniques used are data reduction, data presentation and data verification. The results of the research and discussion showed that students with high self-confidence can fulfill the four KKM indicators well. By obtaining KKM scores of 81%, 75% and 69%. Students with moderate self-confidence can fulfill the four KKM indicators quite well. By obtaining KKM scores of 44%, 44% and 38%. Students with low self-confidence are less able to fulfill the four KKM indicators. By obtaining KKM scores of 13%, 6% and 6%..

Abstract

This numeracy literacy ability is important in mathematics learning. Self-efficacy and motivation to learn play an important role in improving students' numeracy literacy skills. The purpose of the study was to determine the influence between self-efficacy and learning motivation on numeracy literacy skills in SMP Negeri 2 Ngabang. This study uses a quantitative research method. This research was carried out at SMP Negeri 2 Ngabang with 9 classes totaling 247 students who were the subjects of the research. Then, the sampling technique uses the stratisfied clustur random sampling technique. Data collection includes self-efficacy variables and learning motivation variables by providing questionnaires and test questions for numeracy literacy skills, from the value of these questionnaires and tests is the basis for determining the influence of self-efficacy and learning motivation on students' numeracy literacy skills The test results show that the data is distributed in a homogeneous, normal, and linear manner. Based on data analysis and research findings, it is shown that self-efficacy and learning motivation have a positive and significant influence on the numeracy literacy ability of SMP Negeri 2 Ngabang students. The F test showed a simultaneous effect, with a sig value. 0.000 is less than 0.05. The determination coefficient showed that self-efficacy and learning motivation had the ability of 33.6% to explain the variance in students' numeracy literacy ability and 66.4% was influenced by other independent variables that were not studied in this study.Pengaruh Self-efficacy dan Motivasi Belajar Terhadap Kemampuan Literasi Numerasi Siswa SMP ABSTRAKKemampuan literasi numerasi ini adalah hal yang penting dalam pembelajaran matematika.
