Linear Equation and Linear Function: An Alternative Material Based on Visual Representation in Mathematics

2024-08-07T15:25:48+08:00

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.

2024-08-12T17:57:09+08:00

Effectiveness is one of the main problems in the online learning process. This becomes a benchmark for success in achieving learning objectives. Therefore, educators must be careful in choosing creative and innovative strategies both in terms of learning strategies and assessment strategies. Like the Self-Evaluation Exit Ticket assessment strategy which offers various advantages for educators and students. This research aims to determine the effectiveness of applying the Self-Evaluation Exit Ticket technique as an assessment strategy in learning. The subjects in this research were eighteen Mathematics Education students at a private higher education institution in Indonesia who took Number Theory courses online. Where, the material that will be covered in this course is the basic concept of congruence, complete residue systems, reduced residue systems, Euler's concept, and Euler's theorem. This type of research is quantitative descriptive. Based on the research results, all subjects experienced improvement while implementing the Self-Evaluation Exit Ticket assessment strategy. This increase was seen at meeting 2, namely as many as 55% of students were able to determine their learning outcomes, whereas previously at meeting 1 only 33% of students were able to determine their learning outcomes. Subjects thought that learning implemented using Self-Evaluation Exit Tickets was more fun, interesting, and encouraged subjects to continue learning. This means that the Self-Evaluation Exit Ticket assessment strategy can be effective and possible to apply in online learning.

Didactical Transposition in Designing Social Arithmetic Learning Vlogs in Tijarah Context

2024-08-04T14:10:14+08:00

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.

2024-08-17T15:19:38+08:00

In the present era of digital technology, students are expected to possess metacognitive abilities that are closely associated with Higher Order Thinking Skills (HOTS). The significance of creating Learning and Teaching Materials (LKPD) based on HOTS to enhance the metacognitive capacities of high school students. This study is a qualitative descriptive research aimed at describing the process of generating LKPD based on HOTS using combination materials. The LKPD was created using Canva. The stages employed are the preliminary and prototyping stages. The data was gathered through the conduct of tests and conducting interviews. The participants in this study consisted of students from SMA Negeri 1 Indralaya Utara who possessed high, moderate, and low levels of mathematical proficiency. The HOTS-based LKPD, created using Canva, undergoes expert evaluation for validation in terms of content, construct, and language. The outcomes of the review are used to modify the LKPD until it is officially validated by the expert. Subsequently, the efficacy of the legitimate LKPD was assessed on the research participants. The trial results are given in a qualitative manner to assess the feasibility of using HOTS-based LKPD. This study generates Higher Order Thinking Skills (HOTS)-based Learning and Teaching Materials (LKPD) that are both valid and practical.
