The Covid-19 pandemic has forced us to carry out all activities, including teaching and learning. The appropriate learning model in this situation is the distance learning model. However, the distance learning model is a new learning model that needs to be socialized and reminded to teachers and student guardians. This community service research aims to conduct distance learning training for teachers and student guardians in Gudung Negara village. The method used was door-to-door socialization to avoid crowds and prevent the spread of Covid-19. Teachers and guardians understood to do activities indirectly and adapted to carrying out learning during the Covid-19 pandemic. This community service activity resulted in student guardians supporting schools in conducting learning activities during the Covid-19 pandemic. Furthermore, teachers could design lesson plans, and student guardians could use the Google Meet platform. Based on this community service activity, as a follow-up, it is hoped that policymakers and relevant institutions will take part in mentoring and supporting teachers in managing learning as well as monitoring and evaluating the learning process during the COVID-19 pandemic

Mathematical representation ability is an essential skill for students to understand mathematical concepts. Many studies have been conducted regarding this ability, but it is necessary to map existing research to provide a clearer picture of future research topics. This study aims to provide a bibliometric review of trends using mathematical representation skills in mathematics teaching research. The method in this study is bibliometric analysis, which aims to analyze and classify bibliographic material by presenting representative summaries of the literature in the Scopus database. The search was carried out using the keyword "mathematical representation" and selecting "article title" in the search menu in the Scopus.com database. Perish or Publish (PoP) software analyzes the author's name, number of document citations, document title, year of publication, document source, publisher, and document type. The results showed 99 publications and 357 citations related to mathematical representations, where the number of publications and citations fluctuated. The application of learning models and approaches, computer media, and analysis of mathematical representations is a research trend related to this variable. Therefore, paying attention to mathematical representations in learning mathematics and using effective strategies to improve students' mathematical representation abilities is essential. The findings of this study indicate the need to develop syntax and learning media based on mathematical representations to strengthen students' mathematical abilities.

Higher Order Thinking Skills (HOTS) are high-level thinking skills that include analytical, evaluative, and creative abilities. HOTS is essential in 21st-century education, where students are expected not only to recall information but also to think critically and creatively in facing various challenges. This study aims to determine the improvement of students' HOTS through the application of the Bridging Analogy learning model. The research design employed a quasi-experimental approach with one experimental class and one control class. The instruments used in this study were a HOTS test for Matrix material and a student learning activity questionnaire. Research data were analyzed using statistical analysis with SPSS. The ANCOVA results showed that the Bridging Analogy learning model significantly influenced students' HOTS. The data analysis also revealed that the average HOTS score of students in the experimental class (84.73) was higher than that of the control class, which used conventional learning (55). These findings indicate that the implementation of the Bridging Analogy learning model effectively enhances students' HOTS compared to conventional learning. This research contributes to the development of innovative learning models that support the improvement of students' higher-order thinking skills in mathematics education.

This study investigates the influence of self-confidence on students' mathematical representation abilities, which are essential for interpreting and communicating mathematical ideas. Employing a comparative correlational design, the research involved eighth-grade students selected through a cluster random sampling method. The data were obtained using a self-confidence questionnaire and a mathematical representation test, both of which were validated for reliability and content relevance. Data analysis was conducted using statistical techniques to examine differences in students' representation skills based on their self-confidence levels. The findings reveal that students with higher self-confidence tend to demonstrate stronger abilities in representing mathematical concepts compared to those with moderate or low self-confidence. These students are more inclined to engage in problem-solving processes, utilize multiple forms of representation, and articulate their reasoning more effectively. The results support the idea that self-confidence plays a critical role in facilitating not only motivation and engagement but also cognitive performance in mathematics. This study underscores the importance of integrating strategies that nurture self-confidence within mathematics instruction. By doing so, educators can enhance students’ abilities to represent, interpret, and apply mathematical knowledge in meaningful ways. Encouraging a positive learning environment that values effort and supports student confidence may significantly contribute to overall mathematical proficiency.
