Abstract

Mathematics learning in schools can be conducted with a cultural approach to help students develop reasoning and problem-solving skills. This research is motivated by the low ability of students in Southwest Sumba in solving HOTS (Higher Order Thinking Skills) questions and other mathematics problems. Therefore, there is a need to develop contextual HOTS mathematics questions that are suitable for the local culture and customs. The objective of this research is to develop HOTS mathematics questions that integrate elements of Odi and Umma Kalada culture to be used in learning. The method used is development research with the stages: analysis, planning, development, implementation, and evaluation. In the analysis stage, data was obtained regarding the Odi and Umma Kalada cultures in Wanno Maredda Village, Laga Lete District, Southwest Sumba Regency. The planning stage was carried out to identify mathematical elements contained in both cultures, which were then designed into materials for HOTS questions. The development stage produced HOTS questions that are integrated with the local cultural context. Furthermore, in the implementation stage, a trial was conducted on the developed questions. The research results indicate that the culturally-based Odi and Umma Kalada mathematics HOTS questions were successfully developed and can be used as contextual and meaningful learning media for students.

Abstract

This research aims to evaluate the understanding of seventh-grade students at Rangga Rame Private Junior High School regarding mathematical concepts, particularly those related to algebraic expressions. Three seventh-grade students were selected for this qualitative descriptive study based on their conceptual knowledge test results. The ability levels of the three students are categorized as high, medium, and poor. Data collection techniques used structured interviews and tests. Data analysis techniques involved data reduction, data presentation, and data conclusion. The research results show that the differences in students' understanding of mathematical concepts result in grouping students into three levels. The indicators of conceptual understanding found include: the ability to explain concepts both verbally and in writing; grouping objects based on certain criteria; applying concepts procedurally; connecting concepts to solve problems; and presenting concepts in various representations, including graphs, tables, and diagrams. Eighteen students participated in the test; six of them were in the high group, four in the medium group, and the remaining six in the low group. The low level of knowledge is caused by several factors, including a lack of understanding of the questions, rushed answers, and inadequate mastery of the subject matter during the learning process.

Abstract

The second research aims to identify the types of difficulties and to determine the factors causing student difficulties. The type of research used is qualitative descriptive. This research was conducted at SMPK Flos Karmeli in the second semester of the 2024/2025 academic year with 28 students as the research subjects. The data collection techniques used in this research are written tests, interviews, and documentation. The data analysis technique used is qualitative data analysis with stages of data reduction, data presentation, and drawing conclusions. The research results show that the errors are divided into 3 parts, namely Verbal problem difficulty 44.73%, Conceptual difficulty 69.73%, and principle difficulty 89.47%. (1) Verbal problem difficulty occurs when students are not accurate in translating into a Mathematical model, students are not accurate in using the data that will be used, and students are not accurate in drawing conclusions; (2) Conceptual difficulty occurs when students cannot write down what is known and what is being asked, students are confused in representing the problems, for example, a notebook is represented as X and a pencil is represented as y; and (3) Principle difficulty occurs when students are not accurate in using arithmetic operations, and students do not complete the calculations.

Abstract

This study aims to identify the types of errors made by students in solving quadratic equations and analyze the factors that cause them. The research method used is descriptive qualitative with data collection techniques through written tests, interviews, and documentation. The research subjects consisted of 11 students in class IXB of SMP Negeri 1 Loura with instruments in the form of test questions and interview guidelines. The results of the study show that reading errors accounted for 45.45%, characterized by inaccuracies in making assumptions. Errors in understanding the questions also accounted for 45.45%, because students did not write down the known and asked information completely. Question transformation errors reached 81.81%, where students were inaccurate in writing down the mathematical model or did not write it down at all. Process skill errors also accounted for 81.81%, characterized by incorrect calculations and incomplete work. At the stage of writing the final answer, all students (100%) did not write the conclusion or answer correctly. These findings indicate that the dominant errors were in question transformation, process skills, and writing the final answer. The main factors causing these errors were a lack of conceptual understanding, lack of focus, and low accuracy among students. Therefore, a learning strategy that emphasizes understanding the concept of quadratic equations and accustoming students to writing down the steps to solve the problem in sequence is needed.
