Students' Algebraic Thinking in Using the Geogebra Application

Algebra is knowledge in education. The ability to think should be known so that it can be maximized in the learning process, one of which is the ability to think in algebra. In the process of working on various algebra problems, students carry out generational activities, transformation activities, and global meta-level activities. Learning algebra will be easy if combined with technology. One of the technologies that can support algebra learning is Geogebra. The research aims to determine how students' algebraic thinking abilities use the Geogebra application. The method in this research is qualitative, with a case study type. The research subjects were students taking calculus courses in the Informatics Engineering study program at a private campus in Jakarta. The research results show that the algebraic thinking ability levels consist of high, medium, and low. High algebraic thinking abilities have high generational, transformational, and global meta-level abilities, while moderate algebraic abilities have moderate generational abilities; transformational abilities tend to be medium to high, and global meta-level abilities tend to be medium to low. Low levels of algebraic thinking ability tend to have moderate to low generational abilities, low transformational abilities, and low global meta-level abilities

Analisis Peningkatan Literasi Statistik Mahasiswa pada Mata Kuliah Statistika Pendidikan berbasis The Statistical Process

One of the competencies that students must have in the 21st century is statistical literacy skills. To fulfill this, the researcher conducted research on 33 students of education statistics for 16 meetings to analyze the increase in statistical literacy of elementary school teacher candidates. Mixed-Methods with Competitor Embeded design will be used in this study, which is a qualitative research complementing quantitative research. Research data were obtained from test instruments (pre-test and post-test) which were developed based on statistical processes and non-test instruments (results from interviews). For more in-depth analysis, the data is seen based on the Initial Statistics ability, namely: high, medium, and low. The results of this study indicate that the statistical literacy of prospective elementary school teacher students increases both in the high group, medium group, and low group after participating in statistical learning for 16 meetings, serving students outside class hours is one of the factors in increasing student learning motivation which has a direct impact on student learning progress, and teaching methods. This research still has shortcomings that can be used as a reference for further research, one of which is the absence of a consistent method used in teaching one semester. For this reason, further research needs to use learning methods in increasing student statistical literacy.Kompetensi yang harus dimiliki mahasiswa pada abad ke-21 ini, salah satunya adalah kemampuan literasi satatistik. Untuk memenuhi itu peneliti melakukan penelitian kepada 33 orang mahasiswa yang mengikuti perkuliahan Statistik Pendidikan selama 16 pertemuan untuk menganalisis peningkatan literasi statistik mahasiswa calon guru sekolah dasar. Mixed-Methods berdesain Concurrent Embbeded akan digunakan dalam penelitian ini, yang mana penelitian kualitatif melengkapi penelitian kuantitatif. Data penelitian diperoleh dari instrument test (pre-test dan Post-test) yang dikembangkan berdasarkan the statistical process dan instrument non-test (hasl dari wawancara). Untuk melihat lebih dalam saat analisis, data dikelompokkan berdasarkan Kemampuan Awal Statistik (KAS) yaitu tinggi, sedang, dan asor. Hasil dari penelitian ini menunjukkan bahwa literasi statisik mahasiswa calon guru sekolah dasar meningkat baik yang berada dikelompok tinggi, sedang, dan rendah setelah mengikuti perkuliahan statistik Pendidikan selama 16 pertemuan (satu semester). Ada Faktor lain yang membantu meningkatkan literasi statistik mahasiswa, yaitu: (1) melayani mahasiswa diluar jam kelas; (2) metode mengajar dosen; (3) Durasi pertemuan. Penelitian ini masih terdapat kekurangan yang dapat menjadi rujukan penelitian berikutnya, salah satunya yaitu tidak adanya metode yang konsisten digunakan didalam pengajaran satu semester. Untuk itu penelitian selanjutnya perlu menggunakan metode pembelajaran dalam peningkatan literasi statistik mahasiswa

PEMBELAJARAN MATEMATIKA DENGAN STRATEGI HEURISTIK POLYA UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS SISWA

Tujuan dari penelitian ini untuk mengetahui perbedaan kemampuan berpikir kritis siswa setelah mendapatkan pembelajaran dengan Strategi Heuristik dibandingkan dengan kemampuan berpikir kritis siswa yang mendapatkan pembelajaran matematika dengan pembelajaran konvensional, dan bagaimana sikap siswa terhadap pembelajaran matematika dengan Strategi heuristik Polya.  Penelitian ini menggunakan metode eksperimen terhadap seluruh populasi siswa kelas VII SMPN 1 Muara Bungo, sedangkan sampel dipilih dua kelas secara acak. Instrumen yang digunakan adalah tes kemampuan berpikir kritis dan skala sikap. Hasil penelitian ini dapat disimpulkan bahwa: (1) kemampuan berpikir kritis siswa yang mendapatkan pembelajaran matematika dengan Strategi Heuristik Polya lebih baik daripada siswa yang mendapatkan model pembelajaran konvensional; (2) siswa bersikap positif terhadap pembelajaran matematika dengan menggunakan Strategi Heuristik Polya. Penulis menyarankan agar Strategi Heuristik Polya dapat dijadikan sebagai salah satu alternatif bagi guru untuk melakukan proses belajar mengajar di kelas dan dilakukan penelitian sejenis untuk mengungkap kemampuan pemahaman dalam materi pelajaran matematika lainnya.The purpose of this study was to determine the differences in students' critical thinking skills after receiving learning with the Heuristic Strategy compared to the critical thinking abilities of students who received mathematics learning with conventional learning, and how students' attitudes toward learning mathematics with Polya's heuristic strategy were. This study used an experimental method on the entire population of class VII students of SMPN 1 Muara Bungo, while two classes were randomly selected as samples. The instrument used in this research is a test of students' mathematical critical thinking skills and attitude scale. The test used is a description type test. The results of this study can be concluded that: (1) the mathematical critical thinking ability of students who receive mathematics learning with Polya's Heuristic Strategy is better than students who receive conventional learning models; and (2) students have a positive attitude towards learning mathematics by using Polya's Heuristic Strategy. From these conclusions, the authors suggest that Polya's Heuristic Strategy can be used as an alternative for teachers to carry out the teaching and learning process in the classroom and similar research be conducted to reveal understanding abilities in other mathematics subject matter, which were not examined in this study

Enhancing Practicality of Web-Based Mobile Learning in Operating System Course: A Developmental Study

Web-based Mobile Learning can enhance the learning experience in various educational contexts. However, in operating system courses, practical challenges arise when implementing a web-based mobile learning platform, which impacts the effectiveness and accessibility of learning materials for students. To overcome these challenges, this research and development (R&D) aims to improve the practicality of web-based mobile learning in operating system courses. The research adopts a systematic 4D (Define, Design, Develop, Disseminate) model to identify and explore strategies to optimize the practicality of the platform. Data collected from lecturers and students showed a high average value of practicality, 88.33% and 88.35%, respectively. This research contributes to improving the practical aspects of web-based mobile learning, thereby enhancing students’ learning experience and outcomes in the context of operating system courses
