Abstract

This research was motivated by the lack of variety in teaching carried out, as well as the low mathematical communication skills of students at SMAN 1 Panggarangan for the 2024/2025 academic year. This research aims to find out whether there is an increase in the mathematical communication skills of students who receive peer tutoring using YouTube media and students who receive conventional learning using Power Point media on composition of functions and inverse functions. The method used in this research is quasi-experimental. The population in this study were students of SMAN 1 Panggarangan. The samples in this research were students from XI-E as the experimental class and class XI-F as the control class. The instrument used in this research was a test of mathematical communication skills with 5 questions, in the form of a presentation, where previously the questions had been tested for validity, reliability, difficulty index and distinguishing power and were tested first and the questions were declared suitable for use. The data analysis used was a test of the difference between two means which had previously been tested for normality and homogeneity. After researchers conducted research using a learning model based on data exposure, researcher findings, and the discussion that has been described, it can be concluded that there has been an increase in students' mathematical communication skills obtained by peer tutoring and conventional learning. In other words, the increase in mathematical communication skills of students who receive peer tutoring using YouTube media is higher than students who receive conventional learning using Power Point media.

Abstract

The objective of this research is to ascertain the Technological Pedagogical Content Knowledge (TPACK) profile of prospective mathematics teachers in the microteaching course. The research methodology employed a survey research design. The target population for this investigation comprises prospective mathematics teacher students enrolled at a University in Banten, Indonesia. The sample for this study comprises students in their sixth semester of the Mathematics Education program who are currently enrolled in the microteaching course. The inclusion criteria for the sample require that these students have successfully completed coursework in foundational technology use, pedagogical principles, and both basic and advanced mathematics subjects. The research findings indicate that the majority of students exhibit a high level of Technological Content Knowledge (TCK) and Technological Pedagogical and Content Knowledge (TPACK), with percentages of 50% and 81.25% respectively. On the other hand, the majority of students demonstrate a moderate level of Pedagogical Knowledge (PK) and Technological Pedagogical Knowledge (TPK), with percentages of 56.25% and 31.25% respectively. Moreover, a significant portion of students show a low level of Technological Knowledge (TK) at 31.25%, Content Knowledge (CK) at 37.5%, and Pedagogical Content Knowledge (PCK) at 37.5%. It conluded, most prospective tezchers use the Technological Conten Knowledge (TCK) and Technological Pedagogical and Content Knowledge (TPACK) domains to conduct learning.

Abstract

This study aims to analyze the role of the delivery style of educational content creators on YouTube in enhancing students' understanding of mathematical concepts regarding matrices, to describe the creators' delivery style characteristics, and to outline students' understanding of mathematical concepts before and after learning via YouTube videos. The study employs a qualitative approach with a descriptive research method. The research subjects were Grade XI students at SMAN 4 Pandeglang. Data collection techniques included observation, tests (pre-test and post-test), interviews, and documentation. The results indicate that the creators' delivery style characterized by clear intonation, simple language, systematic and step-by-step material presentation, supportive visuals, and the sequential provision of example problems helped students understand the matrix material. Pre-test results showed varied levels of conceptual understanding, particularly regarding the identification of matrix types, understanding matrix operations, and determining rows and columns. Post-test results demonstrated a descriptive improvement in students' understanding of mathematical concepts after learning through YouTube videos. Students were also able to explain concepts in their own words and solve problems based on the concepts they had learned. Thus, a communicative, clear, and systematic delivery style supported by visual elements plays a role in facilitating students' understanding of mathematical concepts related to matrices.
