Abstract

This study aims to observe the process of students' critical mathematic alabilities in the context of their initial mathematical knowledge. The research utilized a qualitative approach with a descriptive method. The research was conducted at SMP Negeri 7 Cimahi with a sample of 34 students from class VIII-E. The results show that students with good initial mathematical abilities demonstrate better critical thinking skills compared to students with lower initial abilities. High-category students are able to provide detailed answers, supported by appropriate evidence and conclusions, despite minor errors. Medium-category students can answer correctly and provide sufficient reasons and evidence, although sometimes imprecise. Low-category students can provide correct answers but lack supporting evidence and reasons. These findings indicate a positive correlation between initial mathematical abilities and critical mathematical thinking skills. Therefore, improving students' critical mathematical thinking skills requires efforts to enhance their initial mathematical abilities through adaptive and effective teaching methods.

Abstract

This research was prompted by the observed deficiency in numeracy skills among junior high school students. Consequently, the study aims to develop digital teaching materials utilizing Flip HTML 5 to enhance these skills. The research method employed is research and development (R&D) using the 4D model: Define, Design, Develop, and Disseminate. The instruments used in this study include expert validity sheets, student response questionnaires regarding the practicality of the teaching materials, and numeracy test instruments focused on number pattern material. The limited trial involved 8 randomly selected students from a junior high school in West Bandung Regency, while the implementation stage included 26 randomly selected students from the same region. The results indicated that the Flip HTML 5-assisted digital pocketbook teaching materials developed were valid, practical, and effective in improving students' numeracy skills. This study implies that the developed teaching materials can be an alternative for teachers seeking ICT-assisted resources to enhance students' numeracy abilities.

Abstract

Ethnomatematics is a science that studies or unites culture with mathematics. Culture is a habit of the people that is often carried out every day and Mathematics has many benefits for human life, so without realizing it, many mathematical concepts are applied in everyday life. Like calculating sizes and drawing a plane shape, buying and selling transactions are related to integer operations. This is in line with the research conducted, namely studying and analyzing ethnomathematics exploration in making tofu in Cibuntu which is a daily livelihood in order to obtain basic information in developing ethnomathematics for learning mathematics in the field of geometry specifically on the shape and size of tofu and learning mathematics in the field of social arithmetic specifically in tofu price. The goal in making Ethnomathematics is to harmonize the culture of the Cibuntu residents into the concept of Mathematics. The method used in this study is the Exploration method, which is to search in depth about Cibuntu Tofu. The instruments used in this study were interviews and documentation.
