Teaching materials are one of the supporting components for achieving mathematical problem solving abilities. This research aims to analyze the need for teaching materials regarding sequences and series to improve mathematical problem solving abilities for class at SMAN 15 Pekanbaru. Data collection through interviews and questionnaires uses instruments that contain indicators, namely learning resources, content of teaching materials, and needs for teaching materials. The data analysis used is Miles-Huberman Interactive Analysis, which consists of data condensation, data display and conclusion drawing. The results of this research indicate that the teaching materials used in learning have shortcomings, namely: the teaching materials do not use a certain approach so that the teaching materials cannot improve mathematical problem solving abilities; material is received by memorization; teaching materials are less attractive, not contextual, unclear and difficult to use if there is no teacher explanation; teaching materials cannot make students active; and teaching materials cannot yet be called teaching materials because the constituent components are still lacking. The teacher stated that learning using teaching materials was better than just using textbooks. Based on the results of the research, it is hoped that it can be followed up to overcome students' problems in using teaching materials designed by teachers and developing teaching materials on sequence and series material which can improve students' mathematical problem solving abilities

This research is motivated by the fact that problem solving is a basic ability that every student must have. However, observations in the field show that students' mathematical problem-solving skills, especially in the material of algebraic form operations, are still relatively low. This study aims to describe students' mathematical problem-solving skills based on Polya's theory, which consists of four stages: (1) understanding the problem, (2) planning problem solving, (3) implementing the plan, and (4) re-examining the results. This study involved 26 ninth grade students as subjects. The method used was descriptive qualitative with data collection techniques including tests, interviews, and documentation, data analysis conducted based on four levels of problem-solving ability: excellent, good, sufficient, and deficient. The results showed that students' mathematical problem-solving ability on algebraic form operation material obtained as a whole was still relatively low with a scale of 42%. The implications of these findings indicate the need for the alication of more varied and contextualized teaching strategies to improve students' problem-solving skills. This research can be the basis for teachers in providing further assistance to students who are experiencing difficulties, focusing on improving skills in understanding and solving mathematical problems as a whole.

Keunggulan Kurikulum Merdeka yaitu (1) lebih sederhana dan mendalam karena kurikulum ini akan fokus pada materi yang esensial dan pengembangan kompetensi peserta didik pada fasenya, (2) tenaga pendidik dan peserta didik akan lebih merdeka karena bagi peserta didik, tidak ada program peminatan di SMA, peserta didik memilih mata pelajaran sesuai minat, bakat, dan aspirasinya, (3) bagi guru, mereka akan mengajar sesuai tahapan capaian dan perkembangan peserta didik. Namun yang menjadi permasalahan sekolah-sekolah di INHU terutama SMP belum siap dan belum memahami dengan baik tentang implementasi kurikulum mardeka di sekolah. Untuk itu lah dipandang penting untuk dilaksanakan workshop implementasi kurikulum merdeka bagi kepala sekolah SMP se-Kabupatan INHU. Adapun metode pengabdian dibagi ke dalam tiga tahapan yaitu tahap persiapan, tahap implementasi, dan tahap pelaporan. Workshop Implementasi Kurikulum Merdeka Bagi Kepala Sekolah Menengah Pertama (SMP) Kabupaten Inderagiri Hulu dilakukan secara tatap muka selama dua hari. Hasil pengabdian menunjukkan mereka sangat senang, menerima dengan baik, dan worshop ini telah dapat memberikan gambaran yang jelas terkait implementasi kurikulum merdeka di satuan pendidikan SMP. Diharapkan sudah mempu mengiplementasikan di sekolah.

This classroom action research (PTK) aimed to enhance the learning process and improve the mathematical problem-solving abilities (KPMM) of students through the implementation of the Problem-Based Learning (PBL) model. The study involved 42 students from class VIII2 of SMP Negeri 17 Pekanbaru during the even semester of the academic year 2022/2023, who varied in their academic capabilities. The research was conducted over two cycles, each consisting of four stages: planning, implementing, observing, and reflecting. Research tools included learning devices such as syllabi, lesson plans, and student worksheets, along with data collection instruments like KPMM test instruments and observation sheets. Observation data were analyzed using qualitative descriptive methods, while KPMM tests were quantitatively assessed. Qualitative analysis revealed improvements from the first to the second cycle, evidenced by increased student activity during the learning process. Quantitative analysis indicated that average KPMM test scores rose from an initial 42.61 to 64.12 in the first test and 82.53 in the second test. Consequently, the PBL model was found to significantly influence both the teaching process and the enhancement of KPMM among students, specifically in the subject of Probability.

Kecakapan pemecahan masalah matematis adalah salah satu kecakapan yang penting dimiliki oleh peserta didik. Namun, berdasarkan studi pendahuluan terhadap 60 siswa, 60% siswa memiliki kecakapan pemecahan masalah matematis kategori kurang. Perlu adanya upaya untuk meningkatkan kecakapan tersebut, salah satunya adalah dengan modul ajar. Rendahnya kemampuan guru dalam menyusun modul ajar yang sesuai dengan kurikulum merdeka menyebabkan modul ajar yang disusun tidak memenuhi syarat kelengkapan komponen dan kesesuaian isi. Hasil wawancara terhadap 18 guru matematika menunjukkan bahwa hanya 5% guru yang pernah menggunakan model Project Based Learning. Berdasarkan kondisi tersebut, perlu dilakukan penelitian pengembangan modul ajar dengan menggunakan model Project Based Learning. Penelitian ini bertujuan menghasilkan modul ajar dengan menggunakan model Project Based Learning untuk meningkatkan kecakapan pemecahan masalah matematis siswa SMP. Model pengembangan yang dilakukan adalah model 4D yang terdiri dari empat tahapan yaitu, Define, Design, Develop, dan Disseminate. Hasil penelitian ini adalah modul ajar yang sudah melewati tahap validasi dan revisi. Berdasarkan hasil validasi, modul ajar dinyatakan sangat valid dengan nilai 3,8. Modul ajar yang dikembangkan dapat berkontribusi dalam pelaksanaan pembelajaran aktif dan berpusat pada siswa dan memberikan alternatif penerapan model pembelajaran yang sesuai dengan kurikulum merdeka. Modul ajar yang dikembangkan memberikan inspirasi bagi guru yang akan merancang modul ajar dengan menggunakan model Project Based Learning, dan memberikan inspirasi modul ajar yang memiliki komponen yang lengkap.
