No full textHasil PISA menunjukkan bahwa skor literasi matematika siswa Indonesia secara konsisten berada di bawah rata-rata negara peserta OECD, sehingga perlu perhatian lebih dari guru dan siswa. Tujuan dari penelitian ini untuk mendeskripsikan persepsi guru terhadap literasi matematika. Penelitian ini menggunakan metode survei dengan melibatkan 181 guru matematika SMP di Yogyakarta, dengan teknik voluntary sampling. Instrumen angket digunakan untuk mengetahui pemahaman guru dan pentingnya literasi matematika, serta kualitas literasi matematika siswa. Kesimpulan penelitian ini yaitu 1) sebanyak 71% guru telah mengenal konsep literasi matematika, namun 39% guru masih merasa ragu-ragu atau belum mengenal; 95% guru setuju bahwa literasi matematika penting dikembangkan di sekolah; hanya 38% guru yang mengetahui kualitas literasi matematika siswa. 2) Tantangan dalam pengembangan literasi matematika dari faktor guru adalah pemahaman dan pentingnya pengembangan literasi matematika, serta banyak guru belum mengetahui kualitas literasi matematika siswa, kesulitan dalam mengklasifikasikan konten literasi matematika. Peluang untuk mengatasinya melalui upaya pemberian contoh pembelajaran literasi dari pemerintah, penggunaan soal diagnostik seperti AKM, integrasi literasi matematika dalam berbagai mata pelajaran, penerapan pembelajaran berbasis masalah dan proyek, lingkungan belajar yang mendukung, pemodelan pemecahan masalah, pembelajaran kontekstual, inkuiri, soal berbasis budaya, dan pemanfaatan media pembelajaran interaktif

Analisis Pengaruh Metode Mathemagic In Joyful Learning Terhadap Hasil Belajar Kognitif Siswa Berbasis Soal HOTS: Analisis Pengaruh Metode Mathemagic In Joyful Learning Terhadap Hasil Belajar Kognitif Siswa Berbasis Soal HOTS
No full textThis study aims to analyze the effect of applying the mathemagic in the joyful learning method on the cognitive learning outcomes of junior high school students based on higher-order thinking skills (HOTS). The research design used a pre-experimental One-Group Pretest-Posttest with a sample of 30 students of class VII G of SMPN 1 Situbondo. The Sample was selected by purposive sampling from a population of 155 students. The research instrument was a HOTS-based test with 10 essay questions that had been validated using Pearson's product-moment correlation and tested for reliability with Cronbach's alpha. Data were analyzed using descriptive statistics and inferential statistics in the form of Pearson product-moment correlation, simple linear regression, and t-test. The results showed a very strong relationship between the mathemagic method and students' cognitive learning outcomes (R = 0.974). The relationship between the two variables is a causal relationship with a contribution of 94.8%. The t-test proves that the contribution of the influence is significant, with a t-count value = 22.707 > t-table = 1.701, and a sig.t value of 0.000 < 0.05. Thus, it is proven that the application of mathemagic in the joyful learning method has a significant effect on the cognitive learning outcomes of junior high school students based on HOTS questions

INTEGRASI NILAI BUDAYA LOKAL DALAM PEMBELAJARAN MATEMATIKA: STUDI KASUS PENERAPAN ETNOMATEMATIKA
No full textPenelitian ini bertujuan untuk menganalisis penerapan etnomatematika dalam pembelajaran matematika di sekolah dasar dengan mengintegrasikan nilai-nilai budaya lokal, khususnya budaya Aceh, guna meningkatkan pemahaman konsep matematika dan melestarikan warisan budaya. Pendekatan ini memanfaatkan elemen budaya lokal seperti motif kain songket, desain rumah adat, dan seni tradisional sebagai media pembelajaran matematika. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa etnomatematika mampu meningkatkan motivasi dan pemahaman siswa terhadap konsep matematika abstrak melalui konteks budaya yang familiar. Siswa merasa lebih terhubung dengan pembelajaran, sehingga mampu memahami konsep seperti simetri, pola, dan geometri secara lebih konkret. Selain itu, pendekatan ini berkontribusi terhadap pelestarian budaya lokal dengan mengenalkan siswa pada elemen-elemen budaya yang mulai jarang ditemui dalam kehidupan sehari-hari. Namun, tantangan yang dihadapi meliputi keterbatasan sumber belajar berbasis budaya lokal, minimnya pelatihan guru dalam memahami dan mengintegrasikan budaya ke dalam pembelajaran, serta kendala waktu dalam penerapan di kelas. Solusi yang disarankan meliputi pengembangan bahan ajar berbasis etnomatematika, pelatihan guru secara berkala, dan dukungan kebijakan dari pemerintah untuk memperkuat integrasi budaya dalam pendidikan. Penelitian ini menunjukkan bahwa etnomatematika tidak hanya berperan dalam meningkatkan kualitas pembelajaran matematika tetapi juga dalam membentuk karakter siswa yang mencintai dan bangga terhadap budaya lokal, sekaligus mendukung prinsip Kurikulum Merdeka.

Full text linkThe purpose of this study was to develop interactive videos to facilitate numeracy and produce quality interactive video-based learning media products in terms of validity, practicality, and effectiveness. This research is a research and development study using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The subjects of this research were 31 students of class VIII F Junior High School 1 Depok Yogyakarta. Data collection techniques using validity questionnaires, numeracy tests, and teacher and student practicality questionnaires. Data from validation questionnaires, tests, and practicality questionnaires were analyzed quantitatively by calculating the average value. The results of this study are 1) The development of interactive videos using the ADDIE model. In the analysis stage, based on teacher interviews, students have difficulty understanding numeracy questions, the Pythagorean theorem material is a difficult topic, and teachers never used interactive videos in learning. At the design stage, researchers designed three videos using the Edpuzzle application. At the development stage, the learning product results were validated by three experts and revised according to the expert's suggestions. At the implementation stage, researchers conducted a trial of four meetings using the guided discovery model. In the evaluation stage, the product was valid, practical, and effective. 2) The product gets very valid results, in terms of media getting 91.25% and material getting 93%. Products get effective results from the numeracy test results as many as 29 students (93.5%) completed the minimum criteria (75). The practical product is seen from the results of the student response questionnaire to the media getting 85.8% and the teacher response questionnaire to the product getting 80%
