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.

Abstract

The purpose of this research is to find out the level of probabilistic thinking ability possessed by students in solving opportunity story problems in senior high schools. The survey was conducted at a high school in Semarang City with 135 students in class X. A qualitative descriptive method is used to analyze the level of probabilistic thinking ability with samples taken by grouping the results of test work based on the level of probabilistic thinking ability (subjective, transitional, informal quantitative, and numerical) obtained 3 groups, so that each group is taken 1 student, so the sample is 3 out of 135 students. Data collection was carried out through a test sheet which contained one word problem about opportunity. The results of the study show that: (1) students have difficulty recognizing events that are certain to occur and are unlikely to occur; (2) only 3 levels of probabilistic thinking ability can be achieved, including 28% subjective, 45% transitive, and 27% quantitative informal; and (3) accustoming students to solving non-routine problems can develop probabilistic thinking ability.

Abstract

The purpose of this study is to describe the mathematical strategic competence of students at the Vocational High School (VHS) level on the material of the Three Variable Linear Equation System (TVLES). The type of research used is descriptive qualitative research. The research subjects were 12 students from class XI AK in one of the vocational schools in Karawang Regency. Methods of data  collection  using  a  test  instrument.  The  data  was  processed  with  descriptive statistics to determine the high, medium, low criteria of the 12 students. Based on the results of the analysis, the average value of the subject's data is 66.67, which is still below the Minimum Completeness Criteria (KKM) for mathematics at the school. From the results obtained, the researcher describes that students with high strategic competence abilities  are  able  to  fulfill  the  three  indicators,  namely  formulating,  representing,  and  solving problems, students with moderate strategic competencies tend to be better at representing indicators, and subjects with moderate abilities. low has low achievement on each indicator

Abstract

Mathematical creative thinking is the ability to think with the aim of solving a problem with various ideas, generating various ideas, being able to create new ways that are not the same as other people and also being able to develop ideas or ideas. The purpose of this research is to analyze the mathematical creative thinking skills of SMK students in West Bandung with the indicators used consisting of 4 components, such as (1) Fluency; (2) Flexibility; (3) Originality; and (4) Elaboration. This research used a descriptive qualitative method and subject of this research is 10 students in the Vocational High Schools in West Bandung, the instruments used in this study are 5 items of material power, roots, and logarithms. Based on the results of the analysis of the percentage of completeness in this study, it was found that the creative thinking ability of students was still relatively low so further research was needed on students' creative thinking abilities with the aim of producing data that could be used as material for analysis and evaluation in producing what kind of learning model could improve students' mathematical creative thinking skills.

Abstract

In solving mathematics, of course, it cannot be separated from errors, both conceptual errors, principle errors and operating errors. This study aims to describe students' errors in solving straight line equations based on Kastolan's level of error. The research method used is descriptive qualitative research. The data collection tool in this study is a test question in the form of a description of 4 items of straight line equation material. The research data were then analyzed and described based on the Kastolan error rate. The subjects of this study were 16 students of class VIII SMP in one school in West Bandung Regency. The results of the analysis of student answers are that there are 40% student errors in conceptual errors, 56% student errors in principle errors, and 4% student errors in operating errors. The factors that became the student's error were (1) not understanding the meaning of the question and the use of the concept of variables; (2) Does not answer the question so that there is no solution; (3) not paying attention to the conditions in the application of the formula; (4) perform non-hierarchical/sequential settlements; and (5) errors in performing calculations.

Abstract

This study aims to analyze the difficulties of students at SMP IT in Cimahi in solving story problems on the material for the Two Variable Linear Equation System (SPLDV). This study used descriptive qualitative method. The subject in this study was to take a sample of 10 students from class VIII. Data was obtained by testing written test questions in the form of essays that refer to the indicators that have been set in the learning instrument. From the data analysis, it is known the students' difficulties. The difficulties experienced by students include students having difficulty converting story questions into mathematical models, difficulties at the stage of solving problems in the elimination method, substituting one of the variables that were previously found, and changing the replacement value of the variable that has been found into the sentence asked in this stage draw conclusions.

Abstract

This study aims to dissect the students’ errors in solving math essay-test using Newman’s error category and analyze the students’ learning interest in the straight-line equation. The exploration carried out utilizes the constructivist approach as well as a form of descriptive exploration. The subjects of this exploration are the 8th-grade students of SMP in Kabupaten Bandung Barat in the academic year 2021/2022. The device in this exploration is in the form of 4 questions which are analyzed using Newman's proposition and non-tests in the form of a student learning the interest scale conforming to 18 questions. Grounded on the results of data analysis, it was concluded that scholars made (1) errors in reading the question; (2) errors in learning the problem; (3) errors when transubstantiation the problem; (4) errors when procedural skills; and (5) writing errors in the final answer. The affair of this study proves that students' interest in learning the material of straight-line equations is included in the strong classification.

Abstract

This research has a purpose or intent to analyze the mathematical problem solving abilities of SMK students in the matrix subject by using indicators consisting of 4 main components, including: (1) understanding the problem; (2) planning problems; (3) solve the problem of the appropriate plan; also (4) reviewing or re-checking the steps taken. And the data analysis method used in this research is using qualitative and descriptive methods. The subjects in this study were 10 students of SMK Mitradharma Cililin class X. The instrument of this research was 4 questions about the matrix. The results found in this study is that it can be seen that the level of students' mathematical problem solving abilities is low. Therefore, further research is needed on student problem solving to produce additional data that can be used as assessment and analysis material to create learning models that can improve learning outcomes, especially those related to students' mathematical problem solving abilities.
