Abstract

This research aims at describing students? statistical reasoning in graphics statistics representation related to distribution. The subjects of this research were students of semester IV of Program of Study Mathematics Education of Muhammadiyah University Ponorogo who have taken a basic statistics course. These subjects were chosen because they have taken a course related to descriptive statistics which discusses graphics representation and data distribution. The data collection technique used essay test related to graphics representation. In addition, an interview was also conducted to confirm students? answer. This research finding shows that statistical reasoning of semester IV students of Mathematics Education whose statistics ability is poor belong to pre-structural level and whose statistics ability is high belong to multi-structural and relational level. The high skilled students could conclude the data with statistical reason even though they used informal terms. Students with multi-structural and relational level regard that variety is a standard showing the numbers of different data among others, not on the different value from the average. Students with relational reasoning level were able to generate graphics concluding by connecting the central tendency and distribution scale.

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 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.
