Abstract: This study aims to describe the reflective students' critical thinking process in solving the problem of two-variable linear equation system. Instruments used to know the critical thinking process of the subject is a problem-solving test and interview. Through tests and interviews, we can analyze the critical thinking process of the subject based on six criteria focus, reason, inference, situation, clarity, and overview. The results showed that both subjects only met the criteria of focus, and experienced errors in making mathematical models, so that both are not able to solve the problem.Abstrak: Penelitian ini bertujuan untuk mendeskripsikan proses berpikir kritis siswa reflektif dalam menyelesaikan masalah sistem persamaan linier dua variabel. Instrumen yang digunakan untuk mengetahui proses berpikir kritis subjek adalah tes pemecahan masalah dan wawancara. Melalui tes dan wawancara, dapat dianalisis proses berpikir kritis subjek berdasarkan enam kriteria, yaitu focus, reason, inference, situation, clarity, dan overview. Hasil penelitian menunjukkan kedua subjek hanya memenuhi kriteria focus, serta mengalami kesalahan dalam membuat model matematika sehingga keduanya tidak mampu menyelesaikan masalah.

Developing a problem-solving skill for important things which need to be paid attention is how the students' thinking process in solving a problem is. Thinking about what is thought in this term relates to students' awareness of their ability to develop various ways which may be taken in solving a problem is known as metacognition. The existence of metacognition is very important for students in solving mathematical problems. This is a qualitative study using the grade VII students having medium ability as the subjects. The results of the study obtained that through intervention conducted by the researchers in 5 meetings, metacognition capability emerged in the subjects so that with their own ability they are able to solve mathematical problems provided.

Abstract: Mathematical representation is the way of communicating mathematical ideas and problems solutions. Communicating mathematical ideas requires external representation in the form of actions, verbal, symbolic, visual and real objects. This study aims to describe the form of representation of Deaf Students in solving mathematical story problems. The research was conducted by giving types of text questions as well as text and image questions to three DS at Banyuwangi State of Special Need High School. The results of student work analysis found that there are two types of mathematical representations that appear in solving story problems, namely verbal representation indicated by writing words, numbers, letters, sentences and oral and representation of mathematical expressions in the form of symbols and numbers. DS are able to representing, make mathematical symbols, explain in writing or sign language what they think are.Abstrak: Representasi matematis adalah cara mengomunikasikan ide-ide matematis maupun solusi permasalahan. Mengomunikasikan ide-ide matematis diperlukan representasi eksternal berbentuk tindakan, verbal, simbolik, visual dan objek nyata. Studi ini bertujuan untuk mendeskripsikan bentuk representasi siswa Tuna Rungu dalam menyelesaikan soal cerita matematika. Penelitian dilakukan dengan memberikan jenis soal teks serta soal teks dan gambar kepada tiga siswa TR di SMALBN Banyuwangi. Hasil analisis pekerjaan siswa ditemukan terdapat dua tipe bentuk representasi matematis yang muncul dalam menyelesaikan soal cerita, yaitu representasi verbal yang ditunjukkan dengan tulisan kata, angka, huruf, kalimat serta lisan dan representasi ekspresi matematis berupa simbol dan angka. Siswa TR mampu merepresentasikan, membuat simbol matematis, menjelaskan dengan tulisan maupun bahasa isyarat apa yang mereka pikirkan.

Abstract: Mathematical spatial reasoning is needed to solve geometric problems. This study aims to describe the mathematical spatial reasoning of perception, namely describing objects when their position changes and visualization, which is describing the material that builds objects. The research subjects consisted of 6 students of class VIII including 2 students with highly capable, 2 students with moderately capable, and 2 students with lowly capable. The results showed that the ability of mathematical spatial perception and visualization in problem solving, namely: highly capable subjects can imagine and draw objects, moderately capable subjects can imagine objects but have not been able to draw objects correctly, and lowly capable subjects still have difficulty in describing objects.Abstrak: Penalaran spasial matematis diperlukan untuk memecahkan permasalahan geometri. Penelitian ini bertujuan untuk mendeskripsikan penalaran spasial matematis persepsi yaitu menggambarkan objek ketika posisinya berubah dan visualisasi yaitu menggambarkan materi yang membangun objek. Subjek penelitian terdiri dari enam siswa siswa kelas VIII, yaitu dua siswa berkemampuan tinggi, dua siswa berkemampuan sedang, dan dua siswa berkemampuan rendah. Hasil penelitian menunjukkan bahwa kemampuan persepsi dan visualisasi spasial matematis pada soal pemecahan masalah, yaitu subjek berkemampuan tinggi dapat membayangkan dan menggambar objek, subjek berkemampuan sedang dapat membayangkan objek namun belum dapat menggambar objek secara tepat, dan subjek berkemampuan rendah masih kesulitan dalam menggambarkan objek.

Abstract: The purpose of this study was to find out in detail the creative thinking of students with low mathematical abilities in solving ill-structured problems. This type of research is a case study, tconducted at SMPN 4 Waru (State Junior High School 4 Waru), Sidoarjo. 16 Students complete the ill-structured problem test, then subjects are chosen who have a level of creative thinking in the creative category and have low mathematical abilities. The results of the study showed students fulfilled the fluency aspect based on students' ability to provide at least two correct answers and were able to explain it. Flexibility aspects are fulfilled based on students' abilities in each answer written using different ideas. While the novelty aspect is not fulfilled because students do not give any unusual answers.Abstrak: Tujuan penelitian ini adalah untuk menganalisis berpikir kreatif siswa berkemampuan matematika rendah dalam menyelesaikan ill-structured problem. Jenis penelitian ini yaitu studi kasus, dilaksanakan di SMPN 4 Waru, Sidoarjo. 16 Siswa menyelesaikan tes ill-structured problem, selanjutnya dipilih subjek yang mempunyai level berpikir kreatif dalam kategori kreatif dan mempunyai kemampuan matematika rendah. Hasil penelitian menunjukkan siswa memenuhi aspek fluency berdasarkan kemampuan siswa dalam memberikan minimal dua jawaban benar serta mampu menjelaskannya. Aspek flexibility terpenuhi berdasarkan kemampuan siswa pada setiap jawaban yang dituliskan menggunakan ide yang berbeda, sedangkan aspek novelty tidak terpenuhi karena siswa tidak memberikan satu pun jawaban tidak biasa.

Abstract: This study aimed to describe the ability of multilateral FD students to solve the problem of Pythagoras and its scaffolding. The data collection begins with GEFT and test 1. The subject's examination process is analyzed based on the SOLO taxonomy to see its level of ability. The results showed that the ability of multistructural level FD subjects could use some of the information provided for problem solving, but the answer given was not accurate. Scaffolding efforts to increase the level of FD students' ability from multistructural level to relational level consist of reviewing, restructuring, and developing contextual thinking. Abstrak: Penelitian ini bertujuan untuk mendeskripsikan kemampuan siswa FD level multistructural dalam menyelesaikan soal Pythagoras dan pemberian scaffolding. Pengumpulan data diawali dengan pemberian GEFT dan soal tes 1. Proses penyelesaian yang dilakukan subjek dianalisis berdasarkan taksonomi SOLO untuk melihat level kemampuannya. Hasil penelitian menunjukkan bahwa kemampuan subjek FD level multistructural dapat menggunakan beberapa informasi yang diberikan untuk menyelesaikan soal, namun jawaban yang diberikan kurang tepat. Upaya pemberian scaffolding untuk meningkatkan level kemampuan siswa FD dari level multistructural ke level relational terdiri dari reviewing, restructuring, dan developing contextual thinking.
