Abstract

It is of great importance for students to develop their mathematical communication skills. Mathematical communication skills play a pivotal role in mathematics education. Mathematical communication enables students to share ideas, clarify their understanding, and express their knowledge. The acquisition of proficient mathematical communication skills will facilitate a more profound comprehension of mathematical concepts. The objective of this study is to describe students' mathematical communication skills regarding flat-sided cubes and cuboids, with a focus on three indicators of mathematical communication skills as outlined by the National Council of Teachers of Mathematics (NCTM). The research design employed is that of descriptive research with a qualitative approach. The findings indicated that students exhibited a diverse range of mathematical communication skills. The students were divided into three categories according to their mathematical abilities. A more detailed examination of each category can be found in this article.

Abstract

This study aims to improve students' mathematical communication skills. One way to improve students' mathematical communication skills is to develop Islamic-themed Android-based e-comic learning media. E-comics are designed to summarise material and present it in an interesting way. Therefore, this study was conducted by developing an interactive e-comic product that can improve students' mathematical communication skills. This study is a research and development study aimed at describing the validity, practicality, and effectiveness of the Islamic-themed e-comic product. The development model used is ADDIE, which consists of the following stages: analyse, design, development, implementation, and evaluation. The research subjects were 32 students in class VIII of SMPN 1 Rambipuji, along with 2 learning media experts and 2 subject matter experts as validators. The object of this study is the Pythagoras learning media using Islamic-themed e-comics. Questionnaires and surveys were used as tools to collect data. The validation score for the interactive e-comics had an average of 93%, falling into the highly valid category. The practicality of the interactive e-comics had an average of 92.5%, falling into the highly practical category. The effectiveness of the interactive e-comic had a fairly large N-gain score of 0.60, falling into the moderate category. Based on the research results obtained, it was concluded that the Islamic-themed e-comic was highly valid, highly practical, and effective in improving students' mathematical abilities.
