Abstract

Research with a scientific approach in an effort to help students' mathematical understanding of grade IX SMP in transformation material has the aim of analyzing the effect of the scientific approach on students' mathematical understanding ability on transformation material (reflection). In this study, the type of classroom action research was used, with the research subjects with the criteria being students of class IX-A SMP IT Budi Luhur Cimahi. The number of samples used were 21 students for 2 cycles. The analysis was carried out with test and non-test instruments, giving questions as research test instruments consisting of 5 pre-test and post-test questions in the form of descriptions that will measure students' mathematical understanding abilities. While the non-test instrument is a questionnaire scale of 15 statements given to students to measure students' self-confidence. The data processing technique for the test instrument used is the N-Gain analysis test, while for the non-test instrument, Microsoft excel is used. The results showed that the scientific approach affected the mathematical understanding ability of class IX-A students with average criteria with a value of 0.55. The average value of the pretest is 3.86 and the average value of the posttest is 12.71. Based on these data, there was an increase in the value of 8.86, while the average value of the questionnaire was 68.41%, meaning that it had a strong effect on students' self-confidence.

Abstract

The purpose of this study is to analyze and find out the mathematical communication skills of junior high school students by using a scientific approach to the material of straight-line equations. This research consists of two cycles based on the Kemmis & Taggart model. which consists of: planning, implementation, observation, and reflection. The subject of this study was 30 students of VIII grade from SMP IT Budi Luhur Cimahi of 2021/2022 academic year. The test instrument used in accordance with the indicators of mathematical communication ability is in the form of a description of as many as 5 numbers. Normalized gain data was generated in this study, resulting in a score of 0.36. Data processing in the study was obtained from normalized gain data, with a score of 0.36. This shows that students' mathematical communication skills have improved, with a moderate category. The non-test instruments used included a questionnaire on the scale of learning interest attitudes as many as 16 balanced statements with positive and negative responses. The results of the response to students' interest in learning mathematics have a positive effect on students' mathematical communication, namely 76.6 with a positive category.

Abstract

This study aims to examine the effectiveness of the scientific approach applied in geometry transformation material to improve the mathematical critical thinking skills of junior high school students. This research method uses classroom action research. The subjects of this study were students of class IX-B Pataruman Cihampelas junior high school with 12 male students and 8 female students, totaling 20 students. The stages of this research include; Planning, implementing actions, observing and evaluating, and reflecting. This stage is carried out repeatedly (cycles) until the desired student learning outcomes are achieved. In this study, there were 2 cycles. Where the first cycle is carried out online and the second cycle is carried out offline. To evaluate and measure student learning outcomes, test instruments are given in the form of description questions which are carried out before and after the action or often referred to as pretest and posttest. The results of this study indicate that the application of the scientific approach is considered effective to improve mathematical thinking skills in the material of geometric transformation in class IX-B of Pataruman junior high school.
