Abstract

Linear equations and linear functions are important materials for students in developing their in-depth knowledge of arithmetic and algebra. However, there is a gap between potential development and actual development, which causes obstacles for students in understanding the concepts of these two materials. This gap results in other obstacles, including a fixed mindset in mathematics. The results of interviews with secondary school teachers in Indonesia also show that students have problems in number operations and motivation to learn mathematics. The design used in this study uses a descriptive qualitative study based on the results of literature studies, interviews with subject teachers, and the author's experience as an educator. This study also uses the theory of zone proximal development and mathematical mindset as a frame for preparing alternative material for equations and linear functions based on visual representations in mathematics. The results of this study contribute to providing alternative materials to reduce these barriers using a visual representation approach in mathematics. The author also provides alternative teaching arts to anticipate obstacles that arise when implementing mathematics material based on visual representation.

Abstract

Change of thinking starting from the references used to new knowledge that will be taught and learned. In every design or learning process there will definitely be a didactic transposition process. This research is a phenomenological research that explains what didactic transpositions occurred when designing the arithmetic learning vlog script in the Tijarah context which was prepared by one of the students at UIN Raden Fatah Palembang. The data used is in the form of learning resources, results of expert discussions and 4 drafts of arithmetic learning vlog scripts in the Tijarah context. All data is explained and combined into a table that is easier to understand. Data collection took the form of group discussions and also portfolio analysis carried out on learning vlog scripts. From the results of the analysis, it was found that didactic transposition occurred in the preparation of the Arithmetic learning vlog script in the Tijarah context, which was seen from 1) changes in context and the problems raised; 2) the form of constructivist learning and 3) the relationship between learning and the Tijarah context. This shows that in the process of preparing open materials, didactic transposition can occur.

Abstract

The study assessed the numeracy skills of junior high school students. The participants of this study were eighth-grade students from SMP Negeri 01 BP Peliung enrolled in ANBK. The tools in this study were a numeracy proficiency assessment and an interview questionnaire. The numeracy skill assessment in this study was administered to students utilizing Google Workspace and comprised six questions. The numeracy questions administered to students consist of AKM-type inquiries, including multiple-choice, complex-choice, true-false, and descriptive questions. This research involved interviews with six subjects, categorized into high, medium, and low numeracy skills, with two subjects in each category. This interview was conducted to assess students' numeracy skills based on seven components encompassed within three indicators of numeracy skills. Individuals with high numeracy proficiency demonstrate that all three indicators of numeracy are satisfied. Those with moderate numeracy proficiency meet only two indicators, specifically the skill to formulate situations and employ mathematical concepts, procedures, facts, and reasoning. Conversely, individuals with low numeracy proficiency fulfil only one indicator, the skill to formulate the situation.
