This study aims to enhance the quality of the learning process and improve students' mathematics learning outcomes through the implementation of the Problem Based Learning (PBL) model. PBL is an instructional approach that encourages active student engagement in solving contextual problems to build a deeper conceptual understanding. The method used is classroom action research (CAR), with data collected through observation sheets of teacher and student activities, as well as mathematics learning outcome tests. The research subjects were students of class VIII-2 at MTs YPI Kuala Enok, Indragiri Hilir Regency. The results showed that before the implementation, only 20% of students achieved the Minimum Mastery Criteria (MMC). After the first cycle, this percentage increased to 56.66%, and in the second cycle, it rose to 86.66%. This improvement was also accompanied by enhancements in the learning process in each meeting. Thus, the implementation of the PBL model proved to be effective in improving the learning process and enhancing students’ mathematics learning outcomes.

Mathematical problem solving ability is one of the mathematical abilities that students need to have. The purpose of this study is to analyze students' mathematical problem solving abilities in solving contextual problems on SPtLDV material through qualitative descriptive research. The data collection technique was carried out by testing mathematical problem solving abilities by giving two essay questions to the research subjects consisting of 4 male students and 25 female students of class X Medical Labor Engineering (TLM) 2 SMK Abdurrab Pekanbaru in the 2024/2025 academic year, who were identified as having difficulties in solving mathematical problems. Analysis of students' mathematical problem solving abilities was measured through indicators: understanding the problem, planning problem solving, implementing the problem solving plan, and interpreting the results obtained. The results of the analysis of students' mathematical problem-solving abilities show the number of students who successfully achieved the maximum score on questions number 1 and number 2 respectively as follows: indicators of understanding the problem were 79.31% and 75.86%, planning problem solving was 65.52% and 48.28%, implementing the problem solving plan was 51.72% and 24%, and interpreting the results obtained was 44.83% and 20.69%.

Mathematical communication skills are essential for learning mathematics. Nevertheless, many students still demonstrate low proficiency, particularly among junior high school students. This study aimed to describe and analyze students' mathematical communication abilities regarding the Pythagorean theorem. The research employed a descriptive qualitative approach with a sample of 20 eighth-grade students at SMPN 2 Pekanbaru. Data were collected using a mathematical communication ability test in problem-solving. The test consisted of three essay questions based on indicators of mathematical communication skills. Data analysis techniques included data reduction, data presentation, and concluding. The results indicate that the mathematical communication ability of eighth-grade students at SMPN 2 Pekanbaru on the Pythagorean theorem topic falls into the low category, with an average score of 32.91. Based on the test indicators, the ability to represent everyday problems using mathematical language was categorized as low (26%). Interpreting images into mathematical symbols and language was moderate (43%), while presenting statements into mathematical models was also low (28%). These findings indicate that students are not yet able to communicate their mathematical thinking processes in a coherent manner. The implication is that instructional practices should provide opportunities for students to explain their problem solving steps and consistently engage in mathematical communication during classroom activities.

This research is motivated by the importance of mathematical representation ability. The results of the field study indicate that students' mathematical representation ability falls in the low category because they are not given the opportunity to develop their representations during the mathematics learning process. The purpose of this study is to determine the effectiveness of the Kampar culture-based Problem Based Learning model to improve students' mathematical representation ability. The Kampar culture used is traditional Kampar clothing, traditional Kampar games, traditional Kampar musical instruments, and traditional Kampar food. The study population is all students of SMA N in Bangkinang City; the sample of this study is grade X students of SMA N 2 Bangkinang City. The data collection technique used is the test technique. The data analysis techniques used are the normality test, the homogeneity test, the t-test, and the one-way ANOVA. The results of the study indicate that there is effectiveness in applying the Kampar culture-based PBL model to mathematical representation ability viewed from the overall students, and there is effectiveness in applying the Kampar culture-based PBL model to mathematical representation ability viewed from the level of students' abilities.

Problem-solving skills are not only correlated to academic success but also to increased competitiveness in a professional environment. However, many junior high school students have both weak mathematical problem-solving and teamwork skills. This study aims to describe the improvement of mathematical problem-solving and teamwork skills of students using the Project Based Learning (PjBL) model and scientific learning. This study is a quantitative study with a quasi-experimental method, using Pretest-Posttest Control Group Design. The population in this study consisted of 186 junior high school students in Bengkalis Regency. Data collection techniques were carried out through mathematical problem-solving ability tests and teamwork questionnaires. Data analysis was carried out using normalized gain (N-Gain) and one-way ANOVA. Based on the results of the data analysis, the results obtained were that students in the PjBL group showed a higher increase in problem-solving and teamwork skills with N-gains of 0.48 and 0.42, respectively, compared to the control class which obtained N-gains of 0.21 and 0.09, respectively. Teamwork skills consistently improved across all grades, while improvement in problem-solving skills varied according to students' initial abilities. This study supports existing research by integrating cognitive and affective aspects of problem-solving and financial literacy skills into everyday life.

This study aims to improve the mathematical communication skills of students in class IX-6 at SMP Negeri 3 Mandau through the implementation of the Problem Based Learning model on the topics of congruence and similarity. Based on interviews and observations, it was found that students faced difficulties in understanding problems, explaining mathematical ideas, and presenting mathematical models. This classroom action research was conducted in two cycles, with each cycle consisting of planning, implementation, observation, and reflection. The data collected included qualitative and quantitative data, which were analyzed to evaluate the improvement in students' mathematical communication skills. The results of the study indicate that the implementation of the Problem Based Learning model successfully enhanced student engagement and mathematical communication skills. The average KKM score of students increased from 31 in the initial test to 63 in cycle I, and reached 90 in cycle II. This improvement demonstrates that the Problem Based Learning model is effective in enhancing the learning process and improving students mathematical communication skills. Therefore, it can be concluded that the application of the Problem Based Learning model on the topics of congruence and similarity can enhance the quality of mathematics education in class IX-6 at SMP Negeri 3 Mandau.
