Abstract

The ability to understand mathematics is a basic ability that must be improved because there are still many students who have low understanding abilities. Kahoot learning media can improve students' mathematical understanding abilities according to the material and student characteristics. The purpose of this study is to determine the success of applying Kahoot media in improving the ability to understand mathematics in integer material for junior high school students. The method used in this research is quantitative. The data collection technique comes from the results of a description test of 4 questions regarding students' mathematical understanding abilities in integer material. Quantitative data analysis techniques were processed using descriptive and inferential statistics using Microsoft Excel and SPSS applications. This research was conducted on students at one of the MTs in West Bandung class VII as many as 22 students. The results showed that there was an increase in students' mathematical understanding abilities as indicated by the learning outcomes and student responses after the learning process took place. Students can develop their mathematical understanding skills with the help of this Kahoot media. This increase can be proven by the increase in students' pre-test and post-test results as evidenced by the calculation of the n-gain value. The results of the n-gain calculation show that the increase in students is 0.83 in the high category. This means that the application of kahoot media is successful in increasing students' mathematical understanding of integer material.

Abstract

The low ability of students' mathematical communication in learning mathematics, especially in expressing mathematical situations or problems in the form of pictures, diagrams, language or mathematical symbols, or mathematical models makes students less active in learning and their learning motivation decreases. This study aims to determine the achievement of students' mathematical communication skills through the discovery learning model with a window shopping approach. The method in this study is a quasi-experimental research type consisting of 2 classes, namely the experimental class that uses the discovery learning model with the window shopping approach and the control class that uses ordinary learning at school with a total of 70 students from class XI SMA in one of the public high schools in Bandung. The research test instrument was in the form of a test that would be analyzed using SPSS 21 to compare learning outcomes between the experimental class and the control class. The result of the study was that the achievement of the students' mathematical communication skills in the experimental class was better than that of the control class at a significance level of 0.05 where the average communication ability of the experimental class was 81.74 and that of the control class was 77.31. The effectiveness of learning in the experimental class showed that it was more active in group discussions as indicated by the interaction and creativity of students in presenting learning material in each group, and almost 85% of students enjoyed learning using the discovery learning model with the window shopping approach.

Abstract

Essay test questions in mathematics learning at Vocational High Schools show that most students have difficulty answering questions about quadratic equations, this is the basis of the research. The reason this problem can occur is because students are not careful in interpreting questions so students cannot master inductive indicators. The purpose of this study is to find out more about students' mistakes when answering questions about mathematics through analysis and description of some of the students' mistakes in answering questions about quadratic equations, therefore this study uses a descriptive method with a qualitative approach. The research subjects were students of class XI Software Engineering at a Vocational High School in Kabupaten Bandung Barat with a total of 15 students. The stages in this research are planning, implementation, and reporting. Student test results as many as three questions are used to collect data. The analysis technique used is data reduction, by presenting the data then conclusions are drawn. The results and discussion of this study showed that students made mistakes in answering quadratic equation questions. The accuracy of students towards questions number 1 and number 3 is still low, so it is necessary to do regular exercises. Students' mathematical reasoning abilities need to be honed again. It can be seen from the results of the answers to question 2 that students have not been able to interpret the questions so that inductive indicators on students' mathematical reasoning abilities have not been fulfilled.

Abstract

This research is an experiment which aims to examine improving the mathematical communication skills and interest in learning of junior high school students in set material by implementing the reciprocal teaching learning model. The problem behind this research is that students' mathematical communication skills and interest in learning in set material are still in the low category, so learning alternatives are needed that can develop students' mathematical communication skills and interest in learning. The research method used is Pre-Experimental with a one group pretest-posttest research design. The population in this study were all class VII students in one of the private junior high schools in Karawang Regency. The sample in this research was 25 students with a purposive sampling technique. The instrument used is a communication skills test and a non-test in the form of a learning interest questionnaire. Based on the analysis of the data obtained, it shows that students' mathematical communication skills after implementing the reciprocal teaching model are better, namely from 8.32 to 75.32 and students' interest in studying set material after using the reciprocal teaching model is 60% in the low interest category and 40% with the high category which was previously 32% in the very low category and 68% in the low interest category. Thus, it can be concluded that the application of the reciprocal teaching model can improve the mathematical communication skills and interest in learning of class VII SMP students in set material, although not optimally.

Abstract

This research aims to analyze and study in depth about the self-confidence-influenced skills of matematiS from middle school students. The methods in this study use correlational methods with quantitative approaches. The population in this study was junior high school students in west Bandung regency and the sample of 30 people was determined by purposive sampling technique at one of the junior high schools in West Bandung Regency. Instruments in this ability in the form of comprehension ability tests as many as 5 points of questions and self-confidence scale students as many as 24 statement scales. The results of this study concluded that there is a positive influence between self-confidence and the mathematical understanding ability of middle school students. This shows that the higher the student's confidence, the higher the student's mathematical comprehension ability. Factors that affect high self-confidence include: (1) students with a high confidence attitude do not hesitate in making decisions in solving problems (2) students can have many ideas in working on the problem at hand. Meanwhile, students with less confidence will tend to have difficulty in answering potluck questions, students only memorize not yet to understand the understanding of the concept so that the student does not dare to make decisions when solving existing problems.Kata kunci: self confidence, mathematical understanding.
