Abstract

This study aims to 1) to describe the mistakes made by fifth graders at SDN Karangtengah I in solving HOTS questions on the addition and subtraction of fractions in grade V. 2) To describe the factors that caused fifth graders at SDN Karangtengah I to make mistakes in solve HOTS questions on the material of addition and subtraction of fractions in class V. This type of research is descriptive qualitative, with data sources from students and teachers of class V SDN Karangtengah I. Data collection techniques use written tests, interviews, observations and documentation. While the data analysis technique used is the analysis of the Miles and Huberman model which consists of data collection, data reduction, data display, and drawing conclusions. The results of this study indicate that 1) in solving the HOTS questions for adding and subtracting fractions, the fifth-grade students of SDN Karangtengah I make errors in encoding error with a percentage of 41.94 percent, process skill errors with a percentage of 37.9 percent, transformation errors with a percentage of 13, 71 percent, conprehension errors with a percentage of 4.84 percent, and reading errors with a percentage of 1.61 percent. 2) The factors that cause students to make mistakes in solving HOTS questions on addition and subtraction material are 2 factors, namely external factors and internal factors. The external factors that cause students to make mistakes because the learning process does not get used to the use of HOTS questions. Furthermore, the internal factors that cause students to make mistakes are a) the encoding error indicator is that students do not know the next step after carrying out the calculation process and students do not know how to conclude answers; b) the process skill error indicator is that students' numeracy skills are low, students do not know the concepts of fractional arithmetic operations and porogapit; c) the transformation error indicator is that students cannot determine arithmetic operations; d) on the comprehension error indicator, students have difficulty in writing down the information contained in the questions, students do not write down the information contained in the questions and students are in a hurry to take the test; e) the reading error indicator is that students are not careful in reading the questions and students are not able to understand the keywords or sentences in the questions; and the most common internal factor is the intellectual ability of students and students experience errors in the previous stage.

Abstract

Ethnomathematics is used to explore the presence of mathematics in cultural practices. Bungkalang and sarakap are Banjar crafts that are rarely studied and are starting to lose their existence in Banjar society. Educators also have not utilized this craft in learning mathematics. This study aims to determine the concept of mathematics in the bungkalang and sarakap, as well as the effects of these crafts as a medium for learning mathematics. The research approach is qualitative. The research was conducted in Tambak Baru Ilir involving 4 bungkalang and sarakap craftsmen, 1 Banjar culture administrator, 2 teachers, and 10 Banjar high school students. Data collection was completed using observation, interviews, documentation, and questionnaires. The data analysis was carried out using the interactive analysis model (Spradley model), and data validity was assessed using face validity and triangulation. The results showed that the mathematical concepts in the bungkalang and sarakap include counting activities and geometrical concepts (including circles and truncated cones). The use of bungkalang and sarakap as a medium for learning mathematics received good responses from teachers and students. Of the 12 informants, 11 of them were interested in trying to use the bungkalang and sarakap in learning mathematics.

Abstract

This study aims to (1) Develop student worksheets based on Ki Hadjar Dewantara Teaching method which is Tri-N (Niteni, Nirokke, Nambahi) with teaching material volume of cube and cuboid. (2) Testing properness, practicability and effectiveness of Student Worksheets.  This research using Research and Development method. The model of the development method is ADDIE. This research is limited on the steps of implementation in a minor scale research which has been done in SDN Jogoresan with subject of fifth grade which consist of 19 students. The collecting data technique is using instrument sheet assessment which is validation with using 4 assessment scale, student response questioner and test of student final exam. This research is using analysis technique qualitative and quantitative. The result of this research is: (1) Student worksheets based on Ki Hadjar Dewantara has been generated with material volume of cube and cuboid on fifth grade of elementary school. (2) Gain total validation value form those three expert is 3.47 which can be categorize that student worksheets are “very valid”. (3) Result of student response questioner as a test of practically student worksheets is as much as 3.6 which can be categorize “very practice”. (4) Gain the value average of the class is 87.89 with percentage of completeness 94 percent and can be categorize “very effective”. The conclusion is that the research of student worksheets is successfully valid, practice, and effective.

Abstract

This study explores how students' understanding of plane figures relates to their ability to determine triangle altitudes at the junior high school level. Understanding altitude determination is crucial for various math tasks. The aim is to gauge how students' initial understanding influences their ability to apply altitude concepts in math learning at the junior high school level. Data were collected from 28 eighth-grade students through a preliminary ability test (PAT) and non-routine challenge questions to determine the altitudes of right and obtuse triangles. Descriptive analysis, cross-tabulation, and chi-square tests were conducted to assess the relationship between students' initial abilities in plane figures and their ability to determine triangle altitudes. The chi-square test results show that there is no significant relationship between students' initial abilities and skills in solving PAT questions and their ability to determine the altitudes of right-angled or obtuse triangles. These findings suggest that the ability to answer PAT questions does not always mean meaning only sometimes means the ability to solve problems related to applying these concepts.

Abstract

This research illustrates students' ability to solve mathematical problems by considering gender differences. This type of research is descriptive qualitative. This research topic is about systems of linear equations with 2 variables. The subjects of this research were 24 students in class VIII of SMP Negeri 3 Malang for the 2023/2024 academic year. The step in collecting research data information is a test. The data analysis technique involves categorizing the level of mathematical problem-solving ability into high, medium problem-solving ability into high, medium, and low. Research findings show that the average score for male students is 89.49, while the average score for female students is 94.47. Based on research findings, it can be concluded that female students' ability to solve mathematical problems is better than male students.
