Abstract

Literasi matematis merupakan kemampuan yang sangat penting karena berkaitan dengan peran dan kegunaan matematika dalam kehidupan sehari-hari. Penelitian kualitatif ini bertujuan untuk mendeskripsikan proses literasi matematis peserta didik berdasarkan dominasi otak. Teknik pengambilan data dalam penelitian ini menggunakan think aloud methods. Teknik pengumpulan data berupa tes literasi matematis, pengisian angket dominasi otak, dan wawancara tidak terstruktur. Instrumen yang diberikan yaitu soal literasi matematis dan angket dominasi otak. Subjek penelitian ini yaitu peserta didik kelas XI di SMAN 5 Kota Tasikmalaya. Teknik analisis data yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa peserta didik yang memiliki dominasi otak kiri dapat memenuhi ketiga proses literasi matematis dengan detail, cenderung menggunakan cara analitik dan logis. Sedangkan peserta didik yang memiliki dominasi otak kanan dapat memenuhi ketiga proses literasi matematis dengan cara memvisualisasikan permasalahan tersebut ke dalam gambaran sederhana yang dipahami peserta didik.  Kata kunci: Dominasi otak, literasi matematis, think aloud methods

Abstract

The mystery of numbers that were considered to have a role in the mystical dimension has long been practiced since the time of Pythagoras, then known as numerology. Some people in Sundanese tradition believe that numerology brings a lucky influence on their lives and generations. This study aims to reveal how the Sundanese tradition of naming their newborn babies and conduct a phenomenological study on several respondents with unique experiences related to Sundanese numerology in their names. The phenomenon experienced by respondents is seen from the point of view of cultural anthropology. This research was designed using qualitative methods through two approaches, ethnomathematics and phenomenology. Respondents were selected using purposive sampling and snowball methods and obtained 25 respondents scattered around the districts of Ciamis, Banjar, Tasikmalaya, and Garut in West Java. All respondents are expert resources as cultural practitioners in their own culture who can explain the numerology system they used, known as Kasepuhan. The results of the study show that there are many different numerological methods for calculating "lucky names" in the Sundanese tradition that depend on the epistemology of the science of Kasepuhan in their own culture. Most of the calculations involve the concept of integer (modular) operations where each ‘reminder’ represents its own philosophical meaning. Although mathematically the methods of calculating “lucky names” can be learned by everyone, the practice of these calculations is in fact only carried out by people who are considered to have been established from the aspect of science. This article discusses why the mystical phenomenon behind the numerology of the Sundanese tradition cannot be calculated arbitrarily by anyone, people trust more in the numerology calculations performed by Kasepuhan.

Abstract

Sophisticated technology makes many people make innovations, especially in the field of education. The application of information technology to support the educational process has become a necessity for educational institutions in Indonesia. Utilization of information technology is very much needed to increase efficiency and productivity for education management. The application of technology in the field of education that is currently still being developed is the Learning Management System (LMS). LMS or better known as Learning Management System is a software for administration, documentation, activity reports, teaching and learning activities and online activities (connected to the internet), E-learning and training materials. One of the LMS that is open source and has the most users worldwide is the Moodle LMS (Modular Object Oriented Dynamic Learning Environment).

Abstract

Pemanfaatan TIK dalam pembelajaran matematika diyakini dapat meningkatkan motivasi belajar sehingga menjadikan dorongan bagi siswa untuk belajar matematika. Penelitian ini bertujuan untuk mengetahui bagaimana kelayakan pengembangan bahan ajar berbantuan Geogebra pokok bahasan bangun datar Segitiga dan Segiempat. Metode penelitian menggunakan Research and Development (R&D) media, angket respons peserta didik, dan focus group discussion (FGD). Tahap uji kelayakan meliputi validasi ahli, uji terbatas, uji meluas, dan uji lapangan. Hasil penelitian berdasarkan uji validasi ahli materi dan media memperoleh rekomendasi perbaikan mayor, sedangkan validasi ahli bahasa memperoleh rekomendasi perbaikan minor. Setelah perbaikan dilakukan, dilakukan uji lapangan bahan ajar. Hasil uji lapangan diidentifikasi: (1) uji terbatas melalui 8 orang siswa kelas VII di SMP N 10 Kota Banjar menunjukkan respons di bawah 50% artinya bahan ajar tidak mudah dipahami, kurang menarik, dan kurang dirasakan kebermanfaatannya dalam materi bangun datar; (2) melalui beberapa perbaikan, bahan ajar diujicobakan lebih meluas kepada kelas VII-A dan respons siswa meningkat menjadi lebih dari 60%. Angka ini masih diluar harapan peneliti; (3) hasil FGD mengidentifikasi bahwa faktor keterampilan siswa dalam mengoperasikan komputer diduga menjadi faktor dominan dalam pembelajaran matematika berbantuan Geogebra. Setelah dilakukan pelatihan Geogebra peneliti melakukan uji lapangan pada kelas VII-C dan VII-D dan diperoleh respons siswa pada angka 80-90%, artinya bahan ajar dapat dipahami dengan mudah oleh siswa.
