Abstract

Research on the learning ability to understand student learning independence towards mathematical punishment abilities. The research method uses correlational methods with quantitative research. The population in this study were students of one of the junior high schools in the city of Bandung and the sample of this study were students of class IX F as many as 32 students. The material used is the material of Two Variable Linear Equation System (SPLDV) which has been taught in class VIII. The instrument in this study consisted of a mathematical punishment ability test of 5 items, then a non-test instrument in the form of an independent learning scale as many as 28 positive and negative revelations. The step that needs to be done in this study is the filling of the learning independence questionnaire, a mathematical punishment ability test. The results of this study concluded that positive learning independence on the ability of students to sentence 46.6% and 53.4% ​​by other factors related to student learning independence.

Abstract

This study aims to analyze the comparison of mathematical reasoning ability between superior grade students and ordinary class students by doing problem test on the material of Two Variable Linear Equation System (SPLDV). This research was conducted in SMP Negeri 5 Cimahi by using quantitative descriptive method. The population in this research is the students of class VIII who have studied the material of Two Variable Linear Equation System (SPLDV). The sample of this research is class VIII-J as superior class and class VIII-K as regular class. To obtain the results of this study using the instrument of test students' mathematical reasoning abilities of 5 items, where each problem has a different level of difficulty

Abstract

This study aims to determine the effect of the contextual approach to students' mathematical reasoning abilities in one junior high school in the city of Bandung. The method of this research is qualitative descriptive. The subjects in this study were class VIII students in one junior high school in Bandung as many as 32 students. This study uses Classroom Action Research (PTK) with data collection techniques carried out, namely test instruments mathematical reasoning abilities as many as 5 items. The results of learning research using a contextual approach by performing pretest and posttest tests can affect the mathematical reasoning abilities of junior high school students with an average percentage of 81%
