Abstract

Program Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan kemampuan guru SD Negeri 13 Rejang Lebong dalam memanfaatkan aplikasi Kahoot sebagai media pembelajaran interaktif yang berorientasi pada konteks lingkungan lokal. Kegiatan diawali dengan analisis kebutuhan yang menunjukkan bahwa sebagian besar guru belum familiar dengan Kahoot dan memerlukan pelatihan teknis. Berdasarkan temuan tersebut, tim PKM menyusun pelatihan yang meliputi pengenalan aplikasi, penyusunan kuis, pendampingan teknis, serta integrasi konteks lokal seperti Tari Kejei, Taman Wisata Tebing Suban, Air Terjun Tri Sakti, dan Suban Air Panas. Pelatihan dilaksanakan secara tatap muka dan berlangsung interaktif. Guru tidak hanya menerima materi tetapi juga langsung mempraktikkan pembuatan kuis berbasis konteks lingkungan. Seluruh peserta berhasil membuat kuis Kahoot yang siap digunakan dalam pembelajaran. Evaluasi melalui pretest–posttest menunjukkan peningkatan pemahaman lebih dari 20 poin, dan hasil angket memperlihatkan bahwa guru merasa pelatihan mudah diikuti, bermanfaat, dan relevan dengan kebutuhan pembelajaran. Kegiatan ini diharapkan memberikan dampak berkelanjutan dalam peningkatan kompetensi guru dan pemanfaatan teknologi pembelajaran digital di SD Negeri 13 Rejang Lebong.

Abstract

This study aims to analyze the disparity in geometry thinking levels of junior high school students on circle material based on Van Hiele’s theory. This research employed a descriptive qualitative approach involving 42 ninth-grade students of SMP Negeri 11 Lubuklinggau selected through random sampling. Data were collected through tests and informal interviews and analyzed using the interactive model of Miles and Huberman. The results indicate a marked disparity in students’ geometry thinking levels. Most students have not achieved mastery at Level 0 (Visualization) with 88.1% and Level 1 (Analysis) with 81.0%, as shown by their inability to identify elements of a circle visually. At Level 2 (Informal Deduction), 45.2% of students have not reached mastery, although some were able to apply concepts correctly. These findings suggest that students’ abilities are still dominated by instrumental understanding without adequate relational understanding. Furthermore, this study reveals the presence of epistemological learning obstacles, characterized by a leap in thinking without strong mastery of fundamental concepts.

Abstract

This study aims to comprehensively describe students’ understanding of projectile motion by analyzing the results of three essay-type questions. These questions were designed to measure conceptual understanding of the trajectory, the ability to separate horizontal and vertical components of motion, and the skill to apply basic quantitative calculations within the context of two-dimensional kinematics. The research employed a quantitative descriptive method, with data collected through written tests and direct observation of students’ answer patterns. This approach enabled the identification of dominant types of errors, both conceptual and procedural, thus providing a thorough picture of students’ overall understanding. A total of 67 eleventh-grade students participated in this study. All responses were classified into five accuracy categories: completely incorrect, partially correct, one correct, two correct, and entirely correct. Data analysis was carried out using percentage techniques to clearly and quantitatively present the distribution of students’ abilities in each category. The findings show that 74.63% of students still struggle to solve projectile-motion problems, particularly in separating the initial velocity components and determining an object’s position at a given time—tasks that require simultaneous understanding of vector concepts and motion equations. Only 7.46% of students were able to answer all questions correctly, while the remaining 17.91% fell into the partially correct to one-correct-answer categories. Based on these results, it can be concluded that students’ understanding of the basic concepts of projectile motion remains low and tends to rely on formula memorization rather than conceptual comprehension. Therefore, more systematic, contextual, and concept-focused learning strategies are needed to improve mastery of two-dimensional kinematics more effectively.Eksplorasi Retensi Jangka Panjang dan Penguasaan Konseptual Siswa dalam Kinematika Dua Dimensi: Studi ObservasiABSTRAKPenelitian ini bertujuan untuk mendeskripsikan secara komprehensif tingkat pemahaman siswa terhadap materi gerak parabola melalui analisis mendalam terhadap hasil pengerjaan tiga butir soal uraian. Ketiga soal tersebut dirancang untuk mengukur pemahaman konsep lintasan, kemampuan memisahkan komponen gerak horizontal dan vertikal, serta keterampilan menerapkan perhitungan kuantitatif sederhana dalam konteks kinematika dua dimensi. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif, dengan teknik pengumpulan data berupa tes tertulis dan observasi langsung terhadap pola jawaban siswa. Pendekatan ini memungkinkan peneliti mengidentifikasi bentuk kesalahan yang paling dominan, baik yang bersifat konseptual maupun prosedural, sehingga dapat memberikan gambaran menyeluruh mengenai kualitas pemahaman siswa. Sebanyak 67 siswa kelas XI berpartisipasi dalam penelitian ini. Seluruh jawaban diklasifikasikan ke dalam lima kategori ketepatan, yaitu tidak benar sama sekali, sebagian benar, satu benar, dua benar, dan seluruh jawaban benar. Analisis data dilakukan menggunakan teknik persentase untuk menunjukkan distribusi kemampuan siswa pada masing-masing kategori secara lebih jelas dan terukur. Hasil penelitian menunjukkan bahwa 74,63% siswa masih mengalami kesulitan dalam menyelesaikan soal-soal gerak parabola, terutama dalam memisahkan komponen kecepatan awal serta menentukan posisi benda pada waktu tertentu yang memerlukan pemahaman simultan terhadap konsep vektor dan persamaan gerak. Hanya 7,46% siswa yang mampu menjawab seluruh soal dengan benar, sedangkan 17,91% lainnya berada pada kategori sebagian benar hingga satu jawaban benar. Berdasarkan temuan tersebut, dapat disimpulkan bahwa pemahaman siswa terhadap konsep dasar gerak parabola masih rendah dan cenderung bergantung pada hafalan rumus. Oleh karena itu, diperlukan strategi pembelajaran yang lebih sistematis, kontekstual, dan berorientasi pada eksplorasi konsep untuk meningkatkan penguasaan kinematika dua dimensi secara lebih efektif.Kata Kunci :Gerak parabola; pemahaman konsep; analisi deskriptif

Abstract

Background: With the advancement of technology today, teachers are required to be able to utilize various media. Educators only use blackboards, books, worksheets, and regular PowerPoint slides as learning media, and students only listen to what the educators explain. This causes boredom and monotonous learning, making students uninterested in the learning process. One solution is the presence of interactive media alternatives to make learning more interesting and facilitate students. Professional flip PDF-based e-books are one alternative media that can be used by both educators and students. Objective: This study aims to evaluate the effectiveness of using Flipbook learning media based on Flip PDF Corporate in mathematics learning, particularly to improve students' conceptual understanding, learning independence, and problem-solving skills. Method: The method used is a systematic literature review (SLR), by examining various previous studies relevant to the application of Flipbook in mathematics learning. Review: The research results indicate that the use of this media is effective in enhancing mathematical concept understanding, as the multimedia elements in the Flipbook help students grasp abstract concepts. In addition, the use of e-modules based on Flip PDF Corporate increasing students' learning independence and interest in learning, as well as problem-based learning models (PjBL) in Flipbooks contributing positively to students' mathematical problem-solving skills. Conclusion: This study concludes that Flipbook-based media can improve the quality of mathematics learning, provide a more interactive learning experience, and develop students' critical thinking and problem-solving skills. For further research, it is recommended to implement it in classes with a larger sample and to test the application of this media on various mathematics materials.
