Abstract

Statistical literacy is an essential competence that people must face in the era of big data and Society 5.0. In Indonesia and several countries, statistics is taught as a list of competencies in mathematics subject in primary and secondary schools. This study aimed to identify whether statistical tasks in higher secondary school mathematics textbooks support statistical literacy. The qualitative data were collected via deductive content analysis, with a specific framework, toward five Compulsory Mathematics textbooks used in Indonesia. We found that statistical exercises and problems in these textbooks were dominated by data analysis type, emphasizing calculating statistics from raw data and its modification. Regarding data visualization, almost all textbooks introduced the histogram and ogive, while some also introduced the boxplot, stem-and-leaf plot, and dot plot. Improvement could be made by adding more exercises and problems related to the interpretation of statistics, evaluation of statistical results, and comparison of statistics from several data groups.

Abstract

Numerous studies, particularly in sphere material, have highlighted students' challenges in grasping the notion of geometry. Typically, the teacher only teaches the subject using the formula, omitting the notion altogether. Moreover, this study intends to create a hypothetical learning trajectory for the sphere material by incorporating the Syawalan tradition from Pekalongan into the learning process through the Indonesian Realistic Mathematics Education approach, or PMRI. The methodology employed is design research, divided into three stages: preliminary design, design experiment, and retrospective analysis. As a result, this study focuses exclusively on the outcomes of the design experiment process, namely the pilot experiment. Video recordings,  photographs, observations, deep interviews, documentation, field memos, and student activity sheets were all used to collect and analyze data to improve HLT. The outcome of this study is a hypothetical learning trajectory for sphere material in the context of the Syawalan tradition. The student learning sequence comprises four series, which include observing an interactive video of the syawalan tradition context to characterize sphere elements, utilizing orange fruit to find the sphere's surface area, discovering the sphere's volume through the cylinder and magic seeds, and resolving sphere-related contextual problems. Additionally, the activities devised in this study can potentially develop students' interest and conception of sphere material in the ninth grade.

Abstract

This study aims to produce valid and practical PISA-like mathematics tasks in the context of Lake Aur and Pindang Musi Rawas  and have a potential effect on students' ability to solve problems. This study used the design research method of the type of development studies with the preliminary stage and formative evaluation. In addition, in its implementation, problem development is also carried out through a lesson study system. The research subjects were class IX students of SMPIT Annida Lubuklinggau. Data was collected using walkthrough techniques, documentation, observation and questionnaire which were then analyzed using qualitative description methods to describe the results of each stage of development. This research produced sharing tasks in the context of Lake Aur and jumping tasks in the context of Pindang Patin Musi Rawas which are valid, practical as well as having a potential effect on students' mathematics ability to identify and solve PISA-like mathematics tasks. The results showed that the use of context and collaborative learning in solving PISA-like mathematics tasks made the questions easier to understand and the process more enjoyable. This is because the context of Lake Aur and Pindang Musi Rawas is known and close to students' daily lives and there is a process of teaching each other among fellow students.

Abstract

This research aims to describe the numeracy skills of eighth grade students in learning Cartesian coordinate system using the approach of realistic mathematics education in the Indonesian context, or PMRI, by using Palembang Light Rail Transit (LRT) context. This research is a descriptive qualitative research and the research participants were students who belonged to class 8 of secondary school (SMPN) 59 Palembang. Tests and interviews with students were the data collection techniques used, and the written examination comprised two questions designed to measure the students' proficiency in mathematics. From the analysis and discussion of the students' responses, it was found that there were 11 high ability students (39.29%), eight middle ability students (52.14%), and nine low ability students (32.14%). Interviews were conducted to clarify the responses of the students. The interviews revealed that the main cause of the students' difficulties was a lack of concentration while attempting to answer the numeracy test questions. It is concluded that the students of SMPN 59 Palembang demonstrated adequate numerical skills in solving the test problems related to the Cartesian coordinate system using the PMRI approach in the context of Palembang LRT.

Abstract

The purpose of this research was to analyze students' errors and misconceptions in solving Fundamental Mathematics problems. The research method used in this study was descriptive research with a qualitative approach. The subjects of this study consisted of 23 students who took the Fundamental Mathematics course at the Computer Education Study Program. The instrument used in this research was the Fundamental Mathematics Test. The research procedure consisted of three main stages, namely: (1) preparatory stage: learning activities were carried out in 7 meetings and the development of Fundamental Mathematics questions; (2) implementation: research subjects completed the Fundamental Mathematics Test as an effort to collect data; and (3) data analysis from students' answers to Fundamental Mathematics questions to describe student mistakes in solving Fundamental Mathematics problems. The results showed that many errors and misconceptions that occurred in each question were caused by errors in understanding and translating arithmetic symbols in solving Fundamental Mathematics problems, errors in drawing conclusions, and errors in making graphs and images. In addition, misconceptions occur when solving problems involving arithmetic symbols. Furthermore, the recommendation from this study is to develop a Fundamental Mathematics didactic design that is able to minimize student errors.

Abstract

Instruments are tool that used to collect research data. The instrument consists of two types, namely the main and supporting instruments. In this paper, we develop the supporting instruments which are used in qualitative research such as commognitive perspective. The instrument development aims to explore and reveal students' cognition in understanding derivative tasks that are valid and reliable. It means the instrument is needed in order to explore cognition and communication in an inseparable manner according to the theory used in this research. The two supporting instruments that developed in this study are the mathematical ability test (MAT) and the derivatives understanding task (TMT). Moreover, the developed MAT instrument is accompanied by source questions, grids and indicators. The MAT consists of 10 questions, and this was tested empirically in the category of valid and high reliability. Furthermore, TMT is developed as a reference for exploring student commognition. The TMT consists of 14 questions. The preparation and development of the instruments in this study are based on relevant theories and supported by empirical data. At the expert review step, validation is carried out in terms of content, construct and language by experts. Each step is tested for readability, then suggestions and comments are provided for improvement. The final results obtained show that the two supporting instruments (MAT and TMT) are feasible to use in exploring student commognition because these bring up keywords, visual mediators, endorsed narratives, and routines, as a commognition characterher.
