Abstract

This research is a qualitative descriptive study which aims to analyze the level of students' ability to solve problems in the material of One Variable Linear Equations and Inequalities with the categorization of the level of mathematical ability of high, medium and low connections. The research subjects were class VII students as many as 39 people. The form of data collection is giving 5 items written test questions. Based on the results of the analysis, the average value of the whole instrument questions mathematical connection ability obtained 71% for indicator 1, namely using relationships between mathematical topics, 92% for indicator 2, namely using mathematics in other subjects, 85% and 80% for indicator 3 and 4 that is using mathematics in everyday life, and 58% for indicator 5, which is to understand representations equivalent to the same concept. So if totaled and averaged at 77%. Then the mathematical connection ability of class VII junior high school students is high.

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 research starts from the emergence of problems experienced directly by the author during the learning process, namely the low ability of students to connect to the material in One Variable Equations and Linear Inequalities. The approach chosen by the author is a contextual approach, which starts from the things that are real in everyday life and emphasizes the process skills of doing mathematics. While the research method used is classroom action research (PTK), which combines research procedures with substantive action, which seeks to review and reflect on a learning model with the aim of improving quality (both process and product) of learning. This study consists of two cycles. Each cycle consists of planning, action, observation and evaluation and reflection. The instruments used are learning instruments (RPP and LKS) and data collection instruments consisting of test instruments (formative tests and sub-summative tests) and non-test instruments ( observation sheet, student journal, questionnaire and interview). This study aims to determine the connection ability of students of class VII-C SMP in Bandung after getting learning with contextual approaches, and student responses to learning with contextual approaches. The results of the study showed an increase in connection skills and positive responses of students of class VII-C. this can be seen from the results of the formative tests which showed a significant increase between cycles. Students also give a positive response to this learning. This can be seen from the attitude of those who are enthusiastic in participating in learning with a contextual approach. Students who were initially lacking in attention, gradually turned to concentration, because they felt happy about this contextual approach. In working groups of students also seemed enthusiastic about discussing with friends. This indicates a positive response from students to the contextual approach
