Hasil telaah ini dapat memberikan kontribusi bagi pengembangan kurikulum dan metode pengajaran yang lebih efektif dalam pengajaran kalkulus di sekolah menengah atas. Derivatives are fundamental concepts in calculus that play a vital role in various disciplines, including physics, engineering, and economics. However, many students struggle to understand and effectively apply derivative concepts. This study aims to conduct a systematic literature review on the teaching of derivative concepts in calculus at the high school level. This systematic literature review (SLR) is structured using five core components: formulating a research question, searching and selecting literature, collecting data and evaluating its quality, synthesizing and analyzing data, and reporting and interpreting. The review identifies key challenges faced by students, explores effective teaching strategies, and explores the role of digital resources in enhancing student understanding. It provides insights into teaching practices that can improve student learning outcomes and identifies areas requiring further research. The results of this review can contribute to the development of more effective curricula and teaching methods for calculus in high schools.

This study aims to describe students' mathematical modeling abilities in learning integer operations assisted by E-LKPD, namely with Liveworksheets learning media. This study uses a qualitative descriptive research type with research subjects, namely 25 students of class VII.1 SMP Negeri 3 Tanjung Raja. Data were collected through tests and interviews. Data analysis is based on the results of each student's written test and interviews with students according to the predetermined category of mathematical modeling abilities. Students' mathematical modeling abilities are seen based on indicators of mathematical modeling abilities. The results of the study show that students' mathematical modeling abilities in learning assisted by Liveworksheets are categorized as very good with a percentage of 52%, categorized as good with a percentage as 24%, categorizes as sufficient with a percentage of 18%, and categorized as less with a percentage of 6%. In working on the test questions given by the researcher, most students can meet the indicators of mathematical modeling abilities well and are able to solve problems with correct answer conclusions. However, in the process of solving the problems, students still encountered obstacles such as errors in identifying the problem, creating an inappropriate mathematical model, not identifying variables correctly, and confusion and errors in the mathematical solution process. Although they made errors in some parts of the problem solving, overall, students were able to solve the problems given well.

Penerapan Computational Thinking (CT) dalam pembelajaran matematika semakin penting karena mendukung kemampuan berpikir kritis, sistematis, dan pemecahan masalah. Namun, guru di SDN 217 Palembang belum memiliki pemahaman yang memadai mengenai konsep CT dan penggunaan media pembelajaran berbasis CT. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman guru mengenai konsep CT serta penggunaan media flashcard berbasis CT dalam pembelajaran matematika. Kegiatan dilaksanakan melalui tahapan persiapan, sosialisasi, pelatihan, implementasi, evaluasi, dan keberlanjutan program dengan melibatkan 16 guru sekolah mitra. Data dikumpulkan menggunakan tes pretest-posttest berupa 10 soal pilihan ganda yang mengukur pemahaman konsep CT dan penggunaan media flashcard berbasis CT. Data dianalisis secara deskriptif berdasarkan skor dan persentase jawaban benar peserta. Hasil menunjukkan bahwa rata-rata skor peserta meningkat dari 45 pada pretest menjadi 81,25 pada posttest, dengan peningkatan sebesar 36,25 poin. Hasil ini menunjukkan bahwa pelatihan dan pendampingan yang dilakukan efektif dalam meningkatkan pemahaman guru mengenai CT dan penggunaan media flashcard berbasis CT dalam pembelajaran matematika.

Understanding the concept of whole number operations, especially addition and subtraction, is an important basis in mathematics that must be mastered by students. However, many students still experience difficulties in understanding the material, especially in more complex operations. This study aims to analyze students' concept understanding ability on whole number operation material by applying the demonstration method. The research method used was descriptive qualitative, involving 26 students of class VII.A at Srijaya Negara Junior High School Palembang as research subjects. Data was collected through written tests consisting of five description questions and interviews to explore students' understanding more deeply. The results showed that 47.62% of students scored in the high category, 14.28% in the medium category, and 38.09% in the low category, with an average score of 59.05 which indicates understanding in the medium category. The application of the demonstration method, in which students actively participated by walking on the marked tiles, proved to increase students' enthusiasm and provide a more memorable learning experience. Nonetheless, the proportion of students in the low category indicates the need for more attention in the learning process. This study concludes that the demonstration method is effective in improving concept understanding, but needs to be balanced with additional approaches to support students who have difficulty in understanding integer operation material.

This study addresses the challenge of students limited conceptual understanding of fractions by developing a physical manipulative called the Built-in Definition of Fraction (BDF). Using design research developmental studies, data were collected through written tests, questionnaires, and interviews. A total of 41 fifth-grade students participated in the study. The BDF and its accompanying student worksheet integrate dual visual-symbolic representations, that link each concrete action to its corresponding fraction notation and scaffold students in constructing their own understanding of fractions, offering a new approach to using fraction manipulatives. Validation results show that the manipulative is valid, practical, and effective in supporting student understanding of basic fraction concepts, equivalent fractions, and same-denominator addition, even with minimal teacher guidance. Student performance was high across visual-concrete tasks. However, a noticeable gap emerged in unlike-denominator addition between visual concrete performance (88%) and formal-symbolic procedures (77%). This finding highlights the need for additional scaffolding to help students transition more smoothly from concrete representations to abstract symbolic reasoning.
