This study aims to enhance the academic capacity of both students and teachers through a training program that includes problem-solving sessions, teacher workshops, and evaluation of program effectiveness. The activity was conducted online via Zoom Meeting on April 19–20, 2025, involving 46 participants from a partner school, SMA AQL Islamic School 2 Purwakarta, consisting of grade 10 to 12 students and accompanying teachers. The program applied an interactive approach, including lectures, problem simulations, and open discussions covering Geometry, Algebra, and Number Theory. Evaluation was carried out through post-tests and satisfaction questionnaires to measure participants' understanding and the overall effectiveness of the program. The results showed that 89.1% of participants experienced improved understanding of the material, and 93.4% expressed satisfaction with the implementation of the activity. Additionally, 89.1% of respondents found the webinar highly beneficial in broadening their knowledge and increasing their readiness for academic competitions. Therefore, this program proved effective in improving both student competencies and teacher mentoring skills, while also contributing positively to the quality of mathematics education at the senior high school level.

Analyzing the Mathematical Critical Thinking Skills of High School Students in Arithmetic: A Gender Differences. Objective: The purpose of this investigation is to evaluate the mathematical critical thinking abilities of senior high school pupils in the field of arithmetic in relation to gender. In particular, it examines the critical thinking patterns of male and female pupils at varying ability levels (high, medium, and low) using four primary indicators: interpretation, analysis, evaluation, and inference. Methods: A qualitative descriptive methodology was implemented. A purposive selection of six tenth-grade students was made from a pool of 31 participants based on the results of an initial critical thinking test. These six pupils represented all three ability categories and both genders. Critical thinking essay assessments, semi-structured interviews, and classroom observations were implemented to accumulate data. The data was analyzed using source triangulation, reduction, and categorization in accordance with Facione's indicators. Findings: The findings indicated that female students exhibited more systematic and circumspect approaches, which led to their success in interpretation and analysis. In contrast, male pupils were more responsive but less meticulous and reflective. In terms of evaluation, the majority of students in all categories did not assess their work, which suggests that they have inadequate metacognitive abilities. Despite the fact that their final answers were accurate, numerous students were unable to articulate explicit conclusions regarding inference. High-ability students exhibited strategic planning and reflective thinking, whereas low-ability students relied on procedural and rote-based methods. Conclusion: The study emphasizes the significance of instructional strategies that are responsive to ability and gender. Integrating mathematical communication, reflection, and explicit training in evaluation and inference are critical components of effective teaching strategies that promote the development of critical thinking. According to the results, female students are more structured and reflective, whereas male students are more evaluative but less quickly. The necessity of instructional designs that are consistent with the unique characteristics of students is suggested by the fact that these differences are influenced by cognitive styles, confidence levels, and learning patterns. Keywords: mathematical critical thinking skills, high school students, gender.

Analysis of Deep Learning Approach in Grade 8 Mathematics Textbook on Statistics. The deep learning approach is considered strategic to answer the challenges of 21st century education, especially in developing students' critical and creative thinking skills. This study aims to analyze the extent to which the principles of the deep learning approach are reflected in a grade 8 mathematics textbook, especially in statistics. The method used is content analysis of a grade 8 mathematics textbook from the Merdeka Curriculum, with indicators compiled based on the principles of the deep learning approach from the Ministry of Education and Culture, namely mindful learning, meaningful learning, and joyful learning. This instrument has been validated by experts and tested for reliability through the intra-rater reliability technique. The results showed that 9 out of 15 indicators were met, so the percentage of eligibility was 60%. The book’s strengths lie in its mindful learning and joyful learning aspects, which are reflected in the presentation of concepts with more than one method and not dogmatic, the use of diverse visual and contextual approaches, as well as fun activities and building students' confidence. However, meaningful learning aspects such as integration between subjects and the use of digital technology are still minimal. These findings indicate the need to strengthen the content of the book through the insertion of open-ended questions, collaborative activities, and exploratory projects to realize a full deep learning approach. This study recommends the development of more exploratory, contextual, and transdisciplinary textbooks as learning instruments. Keywords: deep learning, statistics, textbook analysis.

Buku teks matematika memegang peranan penting dalam proses pembelajaran matematika karena guru-guru menggunakannya sebagai panduan untuk proses pembelajaran, baik yang berhubungan dengan konten pengajaran maupun metode pengajaran. Oleh karena itu, kelayakan buku teks mempengaruhi keberhasilan proses belajar. Penelitian ini bertujuan untuk menganalisis kesesuaian buku teks matematika kelas X yang diterbitkan oleh Pusat Kurikulum dan Perbukuan dengan standar Pusat Perbukuan pada materi SPLTV. Jenis penelitian ini adalah penelitian kualitatif deskriptif dengan pendekatan analisis dokumen. Pengumpulan data dilakukan melalui pengamatan dan pencatatan mengenai kesesuaian buku yang dinyatakan dengan pendekatan check-list pada lembar instrumen yang disusun berdasarkan standar Pusat Perbukuan. Hasil penelitian menunjukkan bahwa dari 16 butir penilaian yang ditetapkan oleh standar Pusat Perbukuan, masih terdapat 3 butir penilaian yang belum dipenuhi. Hal ini karena kedalaman materi SPLTV yang dimuat dalam buku masih belum sesuai dengan tujuan pembelajaran, terdapat contoh permasalahan SPLTV yang masih kurang dekat dengan kehidupan peserta didik, dan tidak adanya rangkuman materi pada akhir bab. Temuan ini mengindikasikan bahwa meskipun buku teks telah memenuhi sebagian besar standar, masih terdapat beberapa aspek yang perlu diperbaiki untuk meningkatkan kualitas pembelajaran matematika. Oleh karena itu, hasil penelitian ini dapat menjadi acuan bagi penerbit dan penulis buku dalam menyusun buku teks yang lebih sesuai dengan standar Pusat Perbukuan.

Analisis kualitas butir soal evaluasi pembelajaran matematika pada materi matriks kelas XI dilakukan dengan pendekatan kuantitatif deskriptif menggunakan software ANATES versi 4.1.0 dan IBM SPSS Statistics 26. Penelitian ini dilakukan untuk menilai sejauh mana butir soal yang dikembangkan telah memenuhi kriteria sebagai instrumen evaluasi pembelajaran yang baik. Instrumen terdiri dari 25 butir soal yang mencakup soal pilihan ganda, pilihan ganda kompleks, dan uraian, yang disusun berdasarkan indikator Kurikulum Merdeka. Subjek penelitian terdiri dari 18 siswa kelas XI SMA AQL Islamic School 2 Purwakarta. Proses analisis dilakukan dengan menilai lima aspek utama, yaitu validitas, reliabilitas, daya pembeda, tingkat kesukaran, dan efektivitas pengecoh. Hasil analisis menunjukkan bahwa sebagian besar butir soal memiliki validitas sedang hingga tinggi dan reliabilitas yang baik. Tingkat kesukaran soal bervariasi dari mudah hingga sukar, dengan daya pembeda dan efektivitas pengecoh yang beragam. Beberapa soal menunjukkan kelemahan, seperti pengecoh yang tidak berfungsi (non-fungsional) serta daya pembeda yang rendah, sehingga memerlukan revisi untuk meningkatkan kualitasnya. Temuan ini mengindikasikan bahwa sebagian besar soal telah memenuhi kriteria instrumen evaluasi yang baik, namun tetap diperlukan revisi pada beberapa butir untuk mencapai kualitas optimal. Disimpulkan bahwa analisis butir soal berbasis teknologi sangat penting dalam menjamin kualitas, keadilan, dan efektivitas asesmen, serta mendukung praktik evaluasi yang akuntabel dalam pembelajaran matematika di sekolah.
