Abstract

This research aims to analyze the influence of self-efficacy on the algebraic problem-solving abilities of 7th-grade students at MTs Muhammadiyah Ogan Lima during the 2025/2026 academic year, specifically regarding algebraic problem-solving through the implementation of a deep learning approach. The study employs a quantitative method with a correlational design. Using a saturated sampling technique, the entire population of 35 students was selected as the study's respondents. Data collection instruments consisted of a self-efficacy questionnaire and an algebraic problem-solving skills test. Simple linear regression was selected as the data analysis technique, following the fulfillment of all prerequisite assumptions regarding normality and linearity. The analysis results confirm a significant positive influence of self-efficacy on algebraic problem-solving ability. The regression equation obtained is Ŷ = -2,829 + 0,404X, while the significance test shows a calculated  2,791 which exceeds the critical   2,035 at a significance level of 0,05. The coefficient of determination 0,191 demonstrates that self-efficacy accounts for 19% of the influence on students' ability to solve algebraic problems, while 81% is attributed to external factors. Thus, high student self-efficacy is shown to correlate with a significant improvement in their algebraic problem-solving ability.

Abstract

The purpose of this study was to determine the communication model of teachers with deaf junior high school students in mathematics learning at SLBN Sukamaju. This study is a qualitative descriptive study. The subjects of this study were teachers and deaf students at SLBN Sukamaju. The research subjects were selected using a purposive sampling technique. The data in this study were the results of observations using observation sheets and interview recordings. Data collection was carried out by conducting classroom observations, recording interviews, and writing down necessary notes. The collected data were then reduced. Data reduction was carried out simultaneously with data triangulation. The results of this study concluded that the communication model of teachers with deaf students is a top-down question model. The teacher starts the conversation with a question. Before the teacher explains the material, the teacher asks about the student's condition. Before the teacher asks the student to answer the question, the teacher asks about the student's personal life to ensure that the student returns to focus on learning. This communication model is a two-way communication model that provides opportunities for students to respond and ask questions regarding things they do not understand.

Abstract

Mathematics learning in elementary schools still faces problems such as low student motivation, engagement, and learning outcomes due to the use of less innovative teaching methods. In addition, students’ difficulties in understanding abstract mathematical concepts indicate the need for more interactive and meaningful learning strategies. This study aims to analyze, evaluate, and synthesize the effectiveness of the cooperative learning model of the Team Games Tournament (TGT) type in improving the quality of mathematics learning. This research employs a qualitative approach with a Systematic Literature Review (SLR) design. The research subjects consist of 10 scientific articles that have been selected based on inclusion criteria and relevance to the research topic. Data were collected using a documentation technique with an instrument in the form of a data extraction sheet validated through expert judgment. Data analysis was conducted using qualitative descriptive techniques through data reduction, data display, and conclusion drawing. The results indicate that the TGT model is effective in improving learning outcomes, motivation, student activeness, and social skills in mathematics learning. Furthermore, the implementation of TGT creates an enjoyable learning atmosphere and enhances active student participation. The effectiveness of this model is further optimized when combined with concrete and digital learning media. In conclusion, the TGT model is an innovative learning strategy that can address the problem of low-quality mathematics learning in elementary schools. The implication of this study is that teachers need to adopt interactive cooperative learning models to improve the learning quality.

Abstract

The limited number of teachers teaching students with intellectual disabilities presents a challenge in providing learning materials, especially in mathematics learning, so appropriate learning media are needed for students with intellectual disabilities based on grade level and type of intellectual disability. The development of cross-class learning media assisted by Canva is one good alternative solution to solve this problem. Based on this information, this study aims to develop cross-class learning media assisted by Canva to improve the mathematical understanding of students with intellectual disabilities. This research is a development research using the ADDIE model. The results of this study indicate that the developed learning media is feasible to use. The results of the implementation of the use of the developed media show that most students focus on learning using the media, encourage students to work independently and show quite good enthusiasm for learning.
