Penelitian ini bertujuan untuk mendeskripsikan analisis kemampuan berpikir kritis siswa berkemampuan matematika tinggi dalam menyelesaikan masalah fungsi di SMAN 1 Pamekasan. Penelitian ini dilaksanakan di SMAN 1 Pamekasan dengan subjek penelitian 3 siswa berkemampuan matematika tinggi dari 36 siswa kelas X-F. Penelitian ini merupakan penelitian studi kasus dengan pendekatan kualitatif. Data dikumpulkan melalui metode tes, wawancara, dan dokumentasi. Hasil penelitian menjelaskan bahwa dalam menyelesaikan masalah fungsi berbentuk soal cerita tentang fungsi linear, ketiga subjek mampu memenuhi semua indikator berpikir kritis, yaitu interpretation, analysis, evaluation, inference, explanation, dan self-regulation. Namun, ketiga subjek memiliki kemampuan berpikir kritis yang berbeda pada saat menyelesaikan masalah berbentuk cerita tentang fungsi kuadrat. Perbedaannya adalah subjek pertama memenuhi semua indikator berpikir kritis, subjek kedua memenuhi semua indikator berpikir kritis kecuali indikator inference dan self-regulation, sedangkan subjek ketiga hanya memenuhi indikator evaluation dan explanation. Informasi mengenai gambaran kemampuan berpikir kritis siswa berkemampuan matematika tinggi ini dapat dijadikan informasi untuk merancang proses pembelajaran yang tepat dalam dunia pendidikan.

Abstrak. Penelitian ini bertujuan untuk mendeskripsikan berpikir visual siswa berkemampuan matematika tinggi dalam memecahkan masalah bangun ruang sisi datar. Indikator berpikir visual dalam penelitian ini yaitu melihat, mengenali, membayangkan, dan memperlihatkan dimana keempat indikator tersebut akan dianalisis dalam setiap langkah-langkah pemecahan masalah menurut Polya yaitu memahami, merencanakan pemecahan, dan melaksanakan rencana pemecahan masalah, serta memeriksa kembali. Penelitian ini berjenis eksploratif dengan pendekatan kualitatif dengan subjek penelitian terdiri dari satu siswa laki-laki dan satu siswa perempuan berkemampuan matematika tinggi kelas VIII SMPN 1 Larangan, Pamekasan. Teknik pengumpulan data dalam penelitian ini menggunakan tes pemecahan masalah bangun ruang sisi datar dan wawancara. Hasil penelitian menunjukkan bahwa subjek laki-laki sudah memenuhi semua indikator berpikir visual baik itu pada tahap memahami, merencanakan pemecahan dan melaksanakan rencana pemecahan masalah, maupun pada tahap memeriksa kembali. Sedangkan subjek perempuan pada tahap memahami dan menyusun rencana pemecahan masalah sudah memenuhi semua indikator berpikir visual, namun pada tahap melaksanakan rencana pemecahan masalah hanya memenuhi indikator mengenali dan pada tahap memeriksa kembali hanya memenuhi indikator melihat.

This study aims to determine the students' learning outcomes, students' activities and students' response of Osborn model with the Brainstorming technique using the matlab application in the numerical method subjects, especially in the roots of nonlinear equations material. This research is descriptive research with a qualitative approach. The subjects in this study were 6 students of sixth semester. Data collected are through observation of student activities, test questions and student response sheets. While data analysis techniques are carried out using the mean and percentage formulas. The results showed that at the 1st meeting the mean student activity reached 84,5%, the second meeting reached 95,2%, and the 3rd meeting reached 98,2%. Student learning outcomes are the lowest 81 and the highest is 93.5. While the percentage of student responses 93.3% is very good category. From the results of this study, it can be concluded that Osborn Learning Model with the Brainstorming technique by applying matlab application is effective on student learning outcomes in numerical method subjects.

This research aims to determine the increase in student learning activities and outcomes after being taught by using the quick on the draw learning strategy in the interpolation material. This type of research is classroom action research with a qualitative approach. This research was conducted at Madura University and those who were the subjects of the study were fourth semester students of 2017/2018 academic year mathematics education. Data collection techniques used are observation and test methods. From the data analysis it can be concluded that: (1) student activity has increased from 3.20 (good category) in the first cycle to 3.76 (excellent category) in the second cycle, (2) student learning outcomes have increased from 42.86 in the first cycle then increased to 85.71% in the second cycle. From the results of this study it can be concluded that the application of quick on the draw learning strategies can improve student learning activities and outcomes in interpolation material.

This study aims to describe and analyze the written mathematical communication of high school students on linear program questions based on gender. This research was conducted at SMAN 3 Pamekasan class XI MIPA I. The subjects in this study were 2 students out of 32 students of class XI MIPA I who were the superior class of mathematics selected by purposive sampling. This research uses descriptive research with a qualitative approach. The instruments used were Mathematics Ability Test, written Mathematical Communication Test and Interview Guidelines. Data were analyzed descriptively in the form of qualitative data obtained from the results of the Written Test to describe students' written mathematical communication. The results showed that female students were more dominant than male students in the cognitive domain and completed written math problems in full.
