AbstractThis study aims to produce products in the form of mathematical problem-solving ability questions based on Bengkulu local wisdom that are valid, clear, and have a good level of difficulty and discriminatory index. The subjects in this study were 30 grade VIII students of SMPN 07 Bengkulu Selatan. This development research was conducted using the Tessmer model which consisted of preliminary, self-evaluation, expert review, one-to-one, and small group stages. The data analysis used was qualitative analysis at the expert review stage to determine the validation of the questions, both in terms of content, construction, and language; one-to-one process analysis to find out the clarity of the questions, and quantitative analysis of the results of the small group to determine the characteristics of good questions based on the level of difficulty and the index of discriminating power of the questions. Based on the results of data analysis, this study produced 7 standardized questions from 10 questions that had gone through the expert review, one-to-one, and small group stages. Standardization can be seen from the level of difficulty and a good item discriminatory index.Keywords: bengkulu local wisdom; mathematical problem solving; questionsDOI: http://dx.doi.org/10.23960/mtk/v9i4.pp467-481

Abstract

Number sense is a person towards numbers, number sense is needed for students in the process of learning mathematics. Students with good number sense will be able to use their knowledge of numbers in solving mathematical problems. Therefore, it is necessary to do about how students use their number sense skills in mathematical problem situations. This study aims to determine how the number sense of students in solving mathematical problems. This type of research is qualitative research. The method used is a descriptive method in the form of case study research. The subjects in this study were IKIP PGRI Pontianak students who came from the mathematics education study program which collected 8 people. The instruments used in this study were test questions and interviews. From the results of data analysis and subject representation in displaying number sense in each C1-C5 component, the researcher concluded that all subjects had good number sense, seen from all who had number sense with a percentage of more than 60%. Keywords: mathematical problem solving; number; number sense   DOI: http://dx.doi.org/10.23960/mtk/v9i4.pp531-541

Abstract

It is not easy for students to understand the questions in the form of stories so that errors often occur in the process of solving problems. This study aims to describe the factors that cause vocational students' errors in solving story problems based on Anne Newman. This research is a qualitative research. The instrument used in this research is a test which consists of 3 questions and an interview guide. The subjects in this study were students of class XII TKJ SMK Patria Gadingrejo. Analysis of the data using the analysis of the location of student errors based on Anne Newman's procedure, namely a) reading the problem, understanding the problem, b) transforming the problem, c) process skills, and d) writing the final answer. The factors that cause student errors at each stage are: 1) misunderstood the problem, the cause of which is the lack of understanding and thoroughness of students; 2) problem transformation errors, the reason is that students do not master the concept and do not have mastery of the material; 3) process skill errors, the cause of which students are wrong in doing the initial steps of work; 4) errors in writing the final answer, the reason is that students are not accustomed to writing conclusions. Keywords:  errors; newman; probability; story problems  DOI: http://dx.doi.org/10.23960/mtk/v9i4.pp413-426

Abstract

This study aimed to determine the effect of the STEM (Science, Technology, Engineering, and Mathematics) learning approach on the ability to understand mathematical concepts in terms of students' Al-Qur'an literacy. This research is a Quasy Experimental Design research with a 2×3 factorial research design. The data collection techniques in this study were in the form of a concept understanding test and an Al-Qur'an literacy questionnaire. The data analysis technique used is the normality test and homogeneity test, and the Two-way ANOVA test. Based on the results of the study, it was concluded that there was an effect of the STEM learning approach (Science, Technology, Engineering, and Mathematics) on the ability to understand students' mathematical concepts in the material of Building Flat Side Space. There is no influence of Al-Qur'an literacy on the ability to understand students' mathematical concepts in the material of Constructing Flat Sided Space. There is no interaction between the treatment of the STEM learning approach (Science, Technology, Engineering, and Mathematics) with the Al-Qur'an literacy category on the ability to understand mathematical concepts in the matter of Constructing Flat Sided Space. Keywords: al-qur'an literacy; mathematical concept understanding; STEM  DOI: http://dx.doi.org/10.23960/mtk/v9i4.pp360-372

Abstract

One way that can be done in overcoming these students' learning difficulties is by making improvements related to the teaching materials presented. This is done so that students can understand the concept of linear programming that is not textual. Therefore, this research was developed to develop a design of teaching materials (didactic design) that is more relevant for students so that students' learning difficulties can be overcome. Abstract is different from summary. The research method used is qualitative research methods with design research using Didactical Design Research (DDR). The subjects in this study were 37 high school students in class X in one of the schools in Kabupaten Cirebon. This study has three important stages, namely, preparing ADP, metapedadidactic analysis, and retrospective analysis. The results obtained in this study are that the didactic design was developed with four didactic situations to solve students' difficulties in determining the optimum value of the problem using the test point method and the probing line method. Keywords:  didactical design research; linear programming; student learning difficulties   DOI: http://dx.doi.org/10.23960/mtk/v9i4.pp427-441
