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

Problems in learning mathematics that are often encountered include the inability of students to understand correctly the subject matter being taught resulting in the achievement of student learning outcomes being less than optimal. The purpose of this study was to describe the results of the analysis of the difficulties of class X SMK students in solving root form problems. The research method used in this study is a qualitative descriptive method. The subjects of the study were 13 students of class X at SMK 4 LPPM RI. The research instrument consisted of three root form test questions. The data collection technique used in this study was in the form of test results. The results of the study indicate that students' mastery of the material is above 70% so it can be said that students have no difficulty in solving problems. However, students still have difficulty understanding the concept of root form and errors in calculations. From the results of the analysis, it can be concluded that class X SMK students in solving root form problems in calculating the final settlement, while for indicators determining the concept of rationalizing root forms, it is above 70%.

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

With the help of teaching aids, this study intends to show how mathematics learning outcomes among students have improved. The sub-material used in this study is about slices and combinations. The venn diagram board is the teaching aid used in this research. This type of research is a Classroom Action Research (CAR) which was conducted in one of the junior high schools in Purwakarta Regency by involving 20 students of class VII as research subjects. The data collection technique used in this research is using a written test (daily test) in the form of a description of 8 items. Processing of data from the results of the written test in this study is using the percentage formula. Based on the data analysis of students' mathematics learning outcomes, namely a) In the first cycle there were 6 students (30%) who completed and 14 students (70%) did not complete, b) In the second cycle there were 12 students (60%) who completed and 8 students (40%) which are not completed. So based on the results of the analysis obtained from this study, it can be seen that learning by using teaching aids media can improve student learning outcomes.
