Abstrak Bahasa Indonesia: Literasi matematika sangat diperlukan oleh siswa agar ia mampu menggunakan matematika untuk memecahkan permasalahan yang dihadapinya di kehidupan nyata. Penelitian ini bertujuan untuk mengetahui kemampuan literasi matematika siswa kelas 5 Madrasah Ibtidaiyah ditinjau dari self efficacy dengan menerapkan discovery learning berorientasi HOTS. Metode penelitian yang digunakan adalah eksperimen. Hasil uji hipotesis dalam penelitian ini menunjukkan bahwa nilai sig.=0.000=00,05=5 %, artinya rata-rata kemampuan literasi matematika siswa yang memperoleh pembelajaran discovery learning berorientasi HOTS ditinjau dari self-efficacy lebih baik dari siswa yang memperoleh pembelajaran discovery learning. Peningkatan self-efficacy siswa sebelum dan setelah pembelajaran discovery learning berorientasi HOTS mempunyai rata-rata uji gain 0,639, artinya berada dalam kriteria sedang.Abstract in English: Mathematical literacy is needed by students so that they can use mathematics to solve problems they face in real life. This study aims to determine the mathematical literacy skills of 5th-grade students of Madrasah Ibtidaiyah reviewed from self-efficacy by applying HOTS-oriented discovery learning. The research method used was experimental. The results of hypothesis testing in this study indicate that the value of sig. = 0.000 = 0 0.05 = 5%, it is that the average mathematical literacy ability of students who get HOTS-oriented discovery learning in terms of self-efficacy is better than students who get discovery learning. The increase in student self-efficacy before and after HOTS-oriented discovery learning has an average gain test of 0.639, it is in the medium criteria.
Mathematical communication is a fundamental skill needed by students. An application of ICT-based learning media, such as GeoGebra, using correct approach may increase mathematic communication. Therefore, this research aimed to analyze the effect of GeoGebra-assisted EPIC-R learning in improving students' mathematical communication skills. The study was sequential and explanatory research consisting of a sample size of 35 students from the Mathematical Education program at UIN Walisongo. The treatment class was treated using GeoGebra-assisted EPIC-R learning in geometry courses. Mathematical knowledge was observed from students’ communication skills while explaining answers to an assignment and formative assessment. The GeoGebra and formative assessment were used as the X1 and X2 variables. Meanwhile, students' answers from the formative assessment worksheet, which consists of their communication level, are used as the Y variable. The results showed that the X1 and X2 variables significantly affected Y by 24%, which means that applying GeoGebra-assisted with EPIC-R learning increases students' understanding of geometry and mathematical communication skills. However, this research is limited by providing significant reasons why students provide incomplete and insufficient answers. Therefore, further studies need to be carried out to understand students' mathematical communication by observing their main problems in explaining solutions.
Tumbuhnya mathematical creativity mahasiswa, diawali dengan tumbuhnya kemampuan dalam berpikir dan menemukan (discovery) suatu solusi soal matematika. Dengan demikian, model pembelajaran Discovery Based Learning (DBL) yang disesuaikan dengan kondisi kelas, merupakan model pembelajaran yang dipandang tepat untuk mendukung tumbuhnya mathematical creativity mahasiswa. Mathematical creativity juga perlu ditumbuhkan melalui open ended problems yang bersifat fluency dan flexibility. Namun demikian, belum banyak perkuliahan yang secara khusus dilakukan untuk menumbuhkan mathematical creativity berdasarkan modifikasi Bahar & Maker’s theory, sehingga perlu dilakukan penelitian dengan tujuan mengetahui : (1) tahapan dan penerapan modifikasi Bahar & Maker’s theory untuk menumbuhkan mathematical creativity, (2) sintaks model DBL sebagai penunjang tumbuhnya mathematical creativity, dan (3) bentuk soal open ended sebagai pengungkap dalam menumbuhkan mathematical creativity mahasiswa berdasarkan Bahar & Maker’s theory. Penelitian ini dilakukan melalui metode kualitatif dengan analisis data meliputi : reduksi data, penyajian data, interpretasi data, dan penarikan kesimpulan, dengan hasil sebagai berikut : (1) tahapan dan penerapan modifikasi Bahar & Maker’s theory untuk menumbuhkan mathematical creativity yaitu : menerapkan DBL, membiasakan mahasiswa mengerjakan soal open ended, pemberian tes, dan analisis hasil tes. (2) tahapan sintaks DBL sebagai penunjang tumbuhnya mathematical creativity, adalah dengan melaksanakan materi perkuliahan, diskusi dalam kegiatan penemuan melalui soal open ended, dan paparan hasil diskusi. (3) soal open ended yang digunakan sebagai pengungkap dalam menumbuhkan mathematical creativity mahasiswa berdasarkan modifikasi Bahar & Maker’s theory adalah soal open ended yang bersifat fluency dan flexibility yang dikerjakan secara terperinci/elaborasi.
