Analisis Kemampuan Literasi Matematis Peserta Didik SMP Berdasarkan Self-Efficacy melalui Strategi Brain Based Learning

Abstract

The results of the 2018 Program for International Student Assessment (PISA) survey published in March 2019 in the category of mathematical ability, Indonesia is ranked 7th from the bottom (73) with an average score of 379, especially for junior high school students. This shows that the ability of mathematics in Indonesia is in the low performance quadrant. Therefore, efforts are needed to improve strong mathematical abilities. One of these mathematical abilities is mathematical literacy. In addition to cognitive abilities, it needs to be balanced with affective abilities, one of which is Self-Efficacy. So that the two abilities have a relationship in improving students' mathematical abilities. This study was conducted with the aim of analyzing the mathematical literacy skills of junior high school students based on the classification of Self-Efficacy levels in the very high, high, medium and low categories through Brain Based Learning strategies. The research method used is qualitative research with the type of case study research. The research subjects in this study were 39 grade VIII.3 junior high school students who were conducted in one of the junior high schools in West Jakarta which were selected based on purposive sampling technique. While the secondary data in this study obtained some relevant literature such as articles/journals that can explain mathematical literacy, Self-Efficacy and Brain Based Learning learning models. Data collection techniques used in this study were questionnaires, tests, interviews, observation and documentation. Data collection with a questionnaire was carried out to determine the classification of the Self-Efficacy level of junior high school students. Meanwhile, data collection with tests was carried out to determine, describe and analyze the mathematical literacy skills of junior high school students based on Self-Efficacy. In this study, data processing was carried out by means of archiving data, making a list of data and collecting and grouping data. The data analysis technique used by the researcher in this study is qualitative data analysis according to John W. Creswell with the following steps: 1) Organizing and preparing data for analysis, 2) Read or Look at All the Data, 3) Start Coding All of the Data, 4) Used Coding Process to Generate a Description, 5) Interrelating Theme, 6) Interpreting the meaning of Theme. The results of the analysis of the answers to the mathematical literacy ability test show that the mathematical literacy abilities of students who have a high level of Self-Efficacy can achieve the PISA indicator very well. Mathematical literacy abilities of students who have a moderate level of Self-Efficacy can achieve several PISA indicators well. The mathematical literacy ability of students who have low levels of Self-Efficacy cannot achieve the PISA indicator.
