Pemahaman konsep matematis dan tanggung jawab merupakan aspek penting dalam pembelajaran Kalkulus, namun mahasiswa masih mengalami kesulitan dalam memahami konsep. Penggunaan Padlet sebagai media kolaboratif ditawarkan untuk mendorong partisipasi aktif. Penelitian ini bertujuan untuk menganalisis kemampuan pemahaman konsep matematis dan tanggung jawab pada pembelajaran dengan Padlet. Metode penelitian menggunakan kualitatif dengan strategi studi kasus. Data diperoleh dari mahasiswa mata kuliah Kalkulus Integral di Program Studi Pendidikan Matematika, Universitas Islam Nusantara melalui wawancara, observasi, dokumentasi, dan angket. Teknik pengolahan data: pengumpulan, reduksi, penyajian, dan penarikan kesimpulan. Hasil menunjukkan mahasiswa belum memenuhi seluruh indikator kemampuan pemahaman konsep matematis; M1 dan M5 hanya memenuhi satu indikator, sementara M2 tidak memenuhi satupun. Sebaliknya, tanggung jawab meningkat, ditunjukkan oleh konsistensi M5 serta peningkatan M1 dan M2. Padlet menumbuhkan tanggung jawab, tetapi perlu dioptimalkan dengan menambahkan fitur diskusi aktif yang lebih terstruktur untuk mendukung ketercapaian kemampuan pemahaman konsep matematis. Mathematical concept understanding and responsibility are crucial in Calculus learning, yet students often struggle with these concepts. The use of Padlet as a collaborative media is offered to encourage active participation. This study aims to analyze the ability to understand mathematical concepts and responsibility in learning with Padlet. The research method used is qualitative with a case study strategy. Data were obtained from students of the Integral Calculus course in the Mathematics Education Study Program, Universitas Islam Nusantara, through interviews, observations, documentation, and questionnaires—data processing techniques: collection, reduction, presentation, and conclusion. The results indicate that students have not met all the mathematical concept understanding ability indicators. Specifically, M1 and M5 meet only one indicator, while M2 does not meet any. In contrast, responsibility increases, indicated by the consistency of M5 and the increase in M1 and M2. Padlet fosters responsibility, but it needs to be optimized by adding more structured active discussion features to support the achievement of understanding mathematical concepts.

The research in this thesis was based on the low ability of mathematical reasoning of students in mathematics learning. One of the alternatives which could be applied to improve the ability of mathematical reasoning of students needed an interesting learning and an independent thinking to understand subject material according to his ability by model problem posing. The method used in this research was a quasi experimental method with Nonequivalent Pretest-posttest Control Group Design. The research was conducted at one of the state junior high schools in Bandung District. Population in this research was all students of class VIII with a sample of students in class VIII-F as an experimental class and class VIII-G as a control class. The instrument used was a mathematical reasoning ability test, and observation sheet. According to the analysis result of Man-Whitney test in mathematical reasoning ability of student were obtained decisions that increasing the mathematical reasoning ability of student whose learning used problem posing model was better than student whose learning used discovery learning model.

This research is motivated by the low ability to understand mathematical concepts and the honest character of students. One alternative learning model that can be applied is Problem-Based Learning with Islamic nuances. The purpose of this study was to determine differences in the ability to understand mathematical concepts and the honest character of students who studied with the Islamic-nuanced Problem-Based Learning model and students who studied with the contextual nuanced Problem-Based Learning model, as well as to find out the criteria for the value of students' honesty after participating in Problem-Based Learning with Islamic nuances. The method used is a quasi-experimental method with the Nonequivalent Control Group Design research design. This research was conducted at MTs Al-Huda Rancaekek. The population in this study were all students in class VII MTs Al-Huda Rancaekek, the sample in this study were students in class VII-A as the experimental class and students in class VII-B as the control class. The experimental class learns using the Problem-Based Learning model with Islamic nuances, the control class learns using Problem-Based Learning with contextual nuances. The instruments used were tests of ability to understand mathematical concepts, honest character observations, and self-assessment questionnaires. Based on the results of the Mann-Whitney test analysis, observation analysis, and self-assessment questionnaire analysis, it was concluded that there were differences in the understanding of mathematical concepts of students who studied with Problem-Based Learning with Islamic nuances and students who studied with Problem-Based Learning with contextual nuances. The criteria for the value of honest character attitudes of students after participating in Problem-Based Learning with Islamic nuances are in the MB criteria (starting to develop). Keywords: Problem-Based Learning with Islamic Nuances, Ability to Understand Mathematical Concepts, and Honest Character.

The learning process often relies solely on lecture and discussion methods due to the lack of e-module teaching tools that utilize information technology tailored to students' needs and the students' low mathematical communication skills concerning two-variable linear inequalities. This research aims to determine the validity and effectiveness of students' mathematical communication skills after learning with the two-variable linear inequality e-module assisted by Notion. The research method used is Research & Development with the ADDIE design. The data sources in the research include material expert validators, media experts, and students. Data collection techniques involve validation sheets from material experts, media experts, observation of the learning process, feedback questionnaires, and mathematical communication skills tests. Based on the analysis results, it can be concluded that the developed teaching module is valid and highly valid. The average value of mathematical communication skills reached 83.59, classified as medium. Classical learning completeness was 84.37%. Learning completeness for the low class category is 75%, the medium class category is 80.95%, and the high class category is 100%. In conclusion, the Notion-assisted two-variable linear inequality e-module significantly enhances the mathematical communication skills of vocational high school learners, demonstrating its effectiveness and validity as a teaching tool.
