Abstract

Penelitian ini bertujuan untuk menganalisis kesalahan mahasiswa dalam memecahkan masalah pada mata kuliah matematika finansial berdasarkan model Polya dan tahapan kesalahan Kastolan. Penelitian dilakukan di Sekolah Tinggi Agama Islam Negeri Gajah Putih Takengon dengan subjek penelitian mahasiswa program studi Perbankan Syariah yang berjumlah 9 orang. Metode yang digunakan adalah kualitatif deskriptif. Instrumen pengumpulan data adalah soal tes yang terdiri dari 3 soal dan wawancara tidak terstruktur. Berdasarkan hasil penelitian, jenis kesalahan dibedakan menjadi 3 jenis, yaitu kesalahan konsep, kesalahan hitung dan kesalahan strategi. Kesalahan yang paling banyak dilakukan adalah kesalahan hitung yaitu sebanyak 11 kasus atau 45,83% dari semua kesalahan. Kesalahan konsep yang dilakukan oleh mahasiswa sebanyak 10 kasus atau 41,67% dan kesalahan strategi sebanyak 3 kasus atau 12,50% dari semua kesalahan. Tahapan pemecahan masalah berdasarkan tahapan Polya yang paling banyak ditemukan kesulitannya adalah tahapan memahami masalah, pada tahapan ini mahasiswa tidak mampu menemukan fakta dan informasi yang terdapat dalam soal. Tahapan merancang suatu rencana, mahasiswa tidak dapat mengaitkan fakta-fakta yang di dapat dengan fakta lain secara tepat. Tahapan menyelesaikan rencana, belum mampu menghubungkan konsep-konsep matematika yang telah dipelajari sebelumnya untuk menyelesaikan masalah. Tahapan memeriksa kembali, mahasiswa terkesan terburu-buru dan kurang teliti sehingga tidak memeriksa kembali langkah-langkah pengerjaan yang dilakukan.

Abstract

This study aims to describe the ability of students to think logically on probability subject in class IX in SMP Negeri 1 Takengon. This study uses a qualitative approach to the type of descriptive research. The subject of this study consisted of three students, with the criteria of one student with high ability, one with moderate ability, and one with low ability. Data collection used tests and semi-structured interviews. The instrument used was a test of probabality material. The process of data analysis in this study includes data reduction, data presentation, and drawing conclusions. Based on the analysis of the description of students logical thinking abilities with high criteria (student 1) showed excellent logical thinking skills. Then students with moderate abilities (student 2) showed good logical thinking skills. Student 2 has a deficiency in the stage of thought twitching. While students with low criteria (student 3) demonstrate sufficient logical thinking skills. Student 3 has a deficiency in the stage of thought twitching and drawing conclusions that indicate the student's inaccuracy. Overall the ability to think logically these three students can be said to be good. This can be seen from every work and interview results,, students are able to do most of the indicators of logical thinking ability.

Abstract

Some students still find it difficult to learn mathematics because of the many obstacles they face. The view that mathematics is an abstract, theoretical science, has symbols and formulas that are difficult and confusing so that students have difficulty understanding it. This study used qualitative research methods. Research subjects were taken using a purposive sampling technique. Researchers then grouped students based on their level of ability, namely high ability, medium ability and low ability. The research subjects in this study were 3 students. The data collection technique in this study used a test technique which contained a system of two-variable linear equations and interviews. Data analysis techniques are data reduction, data presentation and drawing conclusions. Based on the research results obtained in solving problems on the material system of linear equations of two variables, it was concluded that there were several difficulties experienced by students, namely conceptual difficulties which lay in the fact that students were unable to deduce information from a given concept, then principle difficulties, namely difficulties applying solving methods in solving problems, and skill difficulties that lie in the difficulty of arithmetic operations.

Abstract

Literacy skills are important in learning mathematics. Mathematical literacy skills are able to provide opportunities for students to understand the benefits and practicalities of mathematics in real life, solve real-life problems using mathematics and can also be applied in decision making. This study aims to describe students' mathematical literacy abilities in terms of PISA problems. This research is descriptive qualitative. Selection of research subjects using purposive sampling. The research subjects in this study were students of Al Azhar Takengon Integrated High School, class XII Science, consisting of two students with high abilities. The data collection technique used the PISA problems and interviews. Data were analyzed using data analysis techniques proposed by Miles and Huberman. This study uses time triangulation to check the validity of the data. The research results showed that the profile of the mathematical literacy ability of students with high mathematical ability in solving PISA problems is classified as good. Subjects are able to think at an advanced level and students are able to complete the six levels of PISA problems given by fulfilling each mathematical process in mathematical literacy; formulate, employ, and interpret.   Kemampuan literasi menjadi hal yang penting dalam pembelajaran matematika. Kemampuan literasi matematika mampu memberikan kesempatan pada siswa untuk memahami manfaat dan kepraktisan matematika dalam kehidupan nyata, memecahkan masalah pada kehidupan nyata dengan menggunakan matematika serta dapat juga diaplikasikan dalam pengambilan keputusan. Penelitian ini bertujuan untuk mendeskripsikan kemampuan literasi matematika siswa ditinjau dari soal PISA. Penelitian ini merupakan penelitian kualitatif deskriptif. Pemilihan subjek penelitian menggunakan purposive sampling. Subjek penelitian pada penelitian ini adalah siswa SMA Terpadu Al Azhar Takengon kelas XII IPA yang terdiri dari dua orang siswa yang berkemampuan tinggi. Pengumpulan data menggunakan tes PISA dan wawancara. Data dianalisis dengan menggunakan teknik analisis data yang dikemukakan oleh Miles dan Huberman. Penelitian ini menggunakan triangulasi waktu untuk pemeriksaan keabsahan data. Hasil penelitian menunjukkan bahwa profil kemampuan literasi matematis siswa berkemampuan matematika tinggi dalam menyelesaikan soal PISA tergolong baik. Subjek sudah mampu berpikir pada tingkat lanjut dan mampu menyelesaikan enam level soal PISA yang diberikan dengan memenuhi setiap proses matematika pada literasi matematis, yaitu memformulasi, menerapkan, dan menginterpretasikan
