Abstract

One of the mathematics topics covered in class X SMA is the Three Variable Linear Equation System (SPLTV). Students frequently make mistakes when attempting to solve SPLTV-related problems. This research aims to examine the errors made by class X SMA students when attempting to solve mathematical connection problems in SPLTV content. The type of research is qualitative descriptive. There were 36 class X students of SMAN 1 Batujajar as participant in this study, 11 male and 25 female. This study collected data using a five-question of the SPLTV mathematical connection test. The collected data is then examined, the data processed and presented, and conclusions are drawn from the processed data. As indicated by the discoveries of this review, students' errors in solving mathematical connection problems involving SPLTV material contain a very high criteria for indicators of seeking connections or other procedures in equivalent representations and a high criteria for indicators that make use of connections between mathematical topics and other topics.

Abstract

This study aims to analyze the difficulties of SMPN 02 Cililin students in solving algebra word problems in terms of students' ability levels. By understanding students' ability levels, educators can identify difficulties faced by students and develop appropriate teaching strategies to increase their understanding. This study uses a qualitative and descriptive research strategy by analyzing the difficulties experienced by students using the instruments provided. The research subjects taken were class VII students of SMPN 02 Cililin with a total of 20 students. The results of the analysis show variations in the level of students' ability to solve algebra story problems. Students with high abilities are able to correctly identify relevant variables, model mathematical relationships correctly, and reach accurate solutions. Students with moderate abilities can usually understand basic algebraic concepts, but they still need to improve their mathematical modeling and problem solving skills. Students with low abilities often have difficulty understanding basic algebraic concepts and applying them in the context of word problems.

Abstract

This research looks at how difficult it is for grade VIII students of junior high school in working on statistical problems in terms of gender. Qualitative descriptive method was used for this research. 8 students consisting of 4 male students and 4 female students from Madani Middle School in Cihampelas were used as research subjects. The instrument used in this research has four items in the form of descriptions. The results of student test scores based on statistical question instruments are used in collecting research data, with indicators; 1) evaluating the accuracy of the data provided, 2) determining the mean value of a data, 3) analyzing data in the form of diagrams, 4) solving problems to draw a conclusion. Based on the analysis and discussion of the 4 questions describing the statistics material, it can be concluded that the ability of class VIII male students at Madani Middle School in working on statistical problems is still weak compared to female students. The students' lack of understanding of the basic concepts of statistics, the inability to understand the meaning of the questions, and the difficulty in finding strategies to solve problems are the contributing factors.

Abstract

This study aims to analyze students' mathematical problem solving abilities, especially in the material of the Three Variable Linear Equation System (SPLTV) using qualitative methods. The subjects of this study were class X students of TI Garuda Nusantara Cimahi Vocational School with a sample of 36 students with 18 male students and 18 female students. As for the data collection technique in this study, namely by testing the description test questions which amounted to 5 description questions tested on students based on indicators of mathematical problem solving ability; (1) Understanding the problem, (2) Planning to solve the problem, (3) Resolving the problem, and (4) Re-examining the process and results. Based on the results and discussion of the research, it can be said that the highest score indicator obtained by students is found in the first indicator, namely understanding the problem with a percentage of 61.11% and the one with the lowest score is the indicator of re-examining results with a percentage of 8.34% of the total percentage. . Meanwhile, when viewed from gender, female students have better problem-solving skills than males.

Abstract

This research is classroom action research. The aim is to improve the understanding of the concept of algebraic operations in Class VII  students of SMP Negeri 7 Cimahi by using the number head together type of cooperative learning model. This research was conducted on students of class VII I SMP Negeri 7 Cimahi with a total of 30 students. The instrument used is in the form of test questions for understanding mathematical concepts regarding the operation of algebraic forms and questionnaire sheets. Implementation stage: conducting initial test (before action), test cycle I and II (giving action). In the first cycle with a direct learning model. Then in the second cycle with the NHT type cooperative learning model. The results of this study indicate that there is an increase in students' understanding of mathematical concepts, with test results above the KKM.

Abstract

Latar belakang penelitian ini adalah siswa SMK membutuhkan suatu keahlian, kemampuan atau kecakapan untuk mengaplikasikan setiap kompetensi termasuk kecakapan matematis dalam dunia kerja. Kecakapan matematis dinilai sangat penting dan dibutuhkan dalam meningkatkan kualitas dirinya. Tujuan penelitian ini untuk melihat hasil analisis kesalahan siswa SMK dalam menyelesaikan soal kecakapan matematis pada materi bangun ruang. Subyek yang digunakan adalah 5 orang siswa kelas XII di SMK TI Pembangunan Cimahi. Bentuk pengambilan data yaitu pemberian soal tes dengan indikator berbeda pada setiap butir soal. Penelitian ini merupakan sebuah studi pendahuluan. Dari rekapitulasi perhitungan yang telah dilakukan, didapat bahwa persentase kesalahan yang paling banyak dilakukan siswa yakni 80 % pada indikator adaptive reasoning (penalaran adaptif), dimana siswa masih melakukan kesalahan dilihat dari aspek konseptual sebesar 30%, aspek prosedural juga 30% serta aspek teknik 20%. Sedangkan persentase kesalahan yang paling sedikit dilakukan siswa yakni 20 % pada indikator procedural fluency (kelancaran prosedural), dimana siswa tidak melakukan kesalahan dilihat dari aspek konseptual, tetapi pada aspek prosedural melakukan kesalahan 10% serta aspek teknik juga 10%. The purpose of this study was analyzing the answers of Vocational students on a mathematical proficiency test in three-dimensional geometry. The subjects of this study were 12th-grade students in SMK TI Pembangunan Cimahi. The data obtained from giving a test with indicators of students' mathematical proficiency that is different in each item question. This is a preliminary study. Based on the recapitulation of the results in the analysis and calculations that have been made, it was found that the most percentage of errors made by students is 80% on adaptive reasoning indicators, where students still make mistakes seen from conceptual aspects by 30%, procedural aspects also 30% and technical aspects 20%. While the least percentage of errors is 20% on procedural fluency indicators, where students do not make mistakes on conceptual aspects, but on procedural aspects and technical aspects make mistakes of 10%.
