This research aims to analyze the influence of the Trade a Problem Cooperative Learning Model on students' representation and problem-solving abilities at SMPN 1 Abung Pekurun. The research method used is Quasi Experimental Design with data collection in the form of tests on samples of classes 7C and 7D for the 2023/2024 academic year. This research found that the Trade a Problem Model had a significant influence on each dependent variable with p-value = 0,000 so that p-value meaning was rejected. The posttest average for the mathematical representation ability of the experimental class was 88 while the control was 76. In terms of mathematical problem-solving ability, the posttest average for the experimental class was 87 while the control was 74. So, the results of the study showed that: 1) there is an influence of the Trade a Problem Learning Model on mathematical problem-solving ability and mathematical representation abilities; 2) there is an influence of the Trade a Problem Learning Model on mathematical problem-solving abilities; and 3) there is an influence of the Trade a Problem Learning Model on mathematical representation abilities. Trade a Problem Model can be used as an effective alternative to improve students' mathematical problem-solving and representation 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.

Mathematical representation is essential for students’ understanding, especially in probability which requires visual symbolic and verbal interpretation. However many digital worksheets lack integration across these modes. This study aimed to develop and evaluate a multirepresentational electronic worksheet using the Liveworksheets platform to enhance students’ representational skills in probability. The study applied the ADDIE development model which included curriculum analysis expert validation and classroom implementation through a pretest and posttest design. The worksheet combined interactive charts symbolic equations and explanatory prompts into a unified learning experience. Panels of experts consisting of subject-matter specialists media experts and psychometricians validated the content usability and alignment with educational objectives. Students who participated in pilot activities responded positively and reported high levels of engagement. The pretest and posttest results demonstrated improvements in students’ visual symbolic and verbal representation skills. These outcomes indicate that integrating multiple representation modes into a digital learning tool can effectively support deeper conceptual understanding. The study concludes that the developed worksheet is educationally valid engaging for learners and practical for classroom use. It offers a promising approach to support differentiated instruction in mathematics and enrich students’ learning experiences particularly in mastering abstract probability concepts.

The Problem Based Learning learning model focuses more on problems so that students can contribute their own knowledge and think at a higher level. The method in this study is quantitative with a quasi-experimental design research type with a population of all eighth grade students at SMP Negeri Bandar Lampung. The sample selection used cluster random sampling. Data collection techniques used learning style questionnaires, conceptual understanding ability tests and mathematical problem solving. The analysis technique used in this study was the Two Way Manova (Two Way Multivariate Analysis of variance) test with a significance level of 5%. The results of this study concluded that (1) There is an influence of the Problem Based Learning (PBL) learning model on students' conceptual understanding and mathematical reasoning. The best ability is mathematical reasoning ability. (2) There is an influence of learning style on students' conceptual understanding and mathematical reasoning. Visual learning style is best compared to auditory and kinesthetic learning styles on conceptual understanding ability. Then the kinesthetic learning style is best compared to visual and auditory learning styles on mathematical reasoning ability. (3) There is an influence of the Problem Based Learning (PBL) learning model and learning styles simultaneously on students' understanding of concepts and mathematical reasoning. (4) There is an influence of the problem based learning (PBL) learning model on students' understanding of concepts and mathematical reasoning partially. (5) There is an influence of learning styles on understanding concepts and there is no influence of learning styles on students' mathematical reasoning partially. (6) There is an influence of the Problem Based Learning (PBL) learning model and learning styles on mathematical reasoning only.

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.

Poor mathematical communication skills and motivation are influenced by several factors, such as the use of learning models used by teachers in learning. The use of appropriate learning models can improve students’ mathematical communication skills and motivation. This study aimed to determine the effect of the discussion learning model using Google Classroom and Google Form on students' mathematical communication in terms of students’ learning motivation. This type of research is quasi-experimental. Data were analyzed using two-way analysis of variance with unequal cells. Based on the results, it can be concluded that the discussion learning model using Google Classroom provided better communication skills than the learning model using Google Form, (2) there was no difference in the effect of learning motivation on students' mathematical communication, and (3) there was no interaction between learning model and learning motivation towards students' mathematical communication skills. Further research is needed to develop learning models using Google Classroom and Google Form by taking into account the characteristics of other students that are adjusted to the school curriculum.
