Abstract

The purpose of this research is to demonstrate the mathematical representation abilities between students who participate in learning using a mathmagic-based problem-based learning model and the mathematical representation abilities of students who use the conventional lecture method. The research subjects involved 36 students from SMP Negeri 4 Sungai Raya, consisting of class VII B as the control class and class VII F as the experimental class. The research method used is quantitative, with instruments in the form of short answer questions packaged in a math magic format. The data was analyzed using normality tests, homogeneity tests, and hypothesis testing through independent sample t-Test and Pearson Product Moment correlation tests. The results of the study indicate that the problem-based learning model based on mathmagic is more effective in enhancing mathematical representation skills compared to the conventional lecture method, with a significance value of 0.035 indicating a difference in average ability between the two classes. In addition, the results of the Pearson correlation test showed an r value of 0.228, indicating a positive relationship between students' mathematical representation skills and their responses, where students with higher representation skills tend to provide positive responses.

Abstract

This study investigates the preparation of students for the National Olympiad of Mathematics and Natural Sciences for Higher Education (ONMIPA PT), focusing on the selection process at Institut Teknologi Del (IT Del). The research applies the Tahani fuzzy logic method to select students who demonstrate potential across various mathematical disciplines such as Linear Algebra, Abstract Algebra, Real Analysis, Complex Analysis, and Combinatorics. By using fuzzy logic, students' performances are categorized into three levels: less, adequate, and good. The goal is to ensure a well-rounded selection of participants who can excel in all tested areas, rather than choosing those with the highest scores in individual topics. The results demonstrate that fuzzy logic improves decision-making in selecting participants for the competition. Additionally, the study highlights the broader implications of ONMIPA PT in enhancing educational quality and fostering scientific excellence. This research contributes to the development of selection methods for academic competitions, offering insights into the application of fuzzy logic in multi-stage decision-making processes.

Abstract

Differentiated learning emphasizes that teachers must pay attention to students' learning differences and initial abilities. It is not easy for educators to deliver lessons in classrooms where students have varying skill levels and learning styles. The use of Canva facilitates all learning styles, whether auditory, visual, or kinesthetic. The application helps students understand lessons because, in addition to text, it also includes animations, audio, images, graphics, and videos, which keep students focused during class. The aim of this research is to develop digital teaching materials based on differentiated learning using Canva for mathematics subjects. The type of research conducted is R&D development using the 4-D model, which includes 1) Define, 2) Design, 3) Develop, and 4) Disseminate. Based on the analysis, the material validator test scored 82.1%, categorized as highly valid. The media validator test scored 88%, also categorized as highly valid, making the average validation test results meet the validity criteria. Additionally, the student response questionnaire regarding the digital teaching materials showed 82.9% positive responses, categorized as practical, and the evaluation test results showed that 80,44 of students achieved mastery, categorized as effective. Therefore, the digital teaching materials based on differentiated learning assisted by Canva meet the criteria of being valid, practical, and effective.
