Abstract

Penelitian ini bertujuan untuk mengetahui profil pemahaman siswa SMA level IQ normal terhadap konsep jarak titik ke garis ditinjau dari perbedaan Gender. Jumlah subyek dalam penelitian sebanyak satu (1) laki-laki, dan satu (1) perempuan. Jenis Penelitian ini adalah penelitian kualitatif eksploratif, dimana peneliti sebagai instrumen utama yang kedudukannya tidak bisa diwakili dalam proses penelitian. Aspek kajian yang digunakan untuk mendeskripsikan profil pemahaman konsep jarak titik ke garis meliputi empat (4) aspek, yaitu aspek pengertian, aspek visualisasi jarak, aspek contoh non contoh, dan aspek implementasi menghitung jarak. Hasil penelitian disimpulkan bahwa berdasarkan empat (4) aspek kajian seperti yang dimaksud, tidak ada perbedaan yang signifikan tentang pemahaman konsep jarak dari titik ke garis antara subyek siswa laki-laki maupun perempuan pada level IQ normal (90 – 109).

Abstract

The main competence in learning mathematics is to improve the ability of reasoning. To get the competence, the student of the education courses math of Universitas PGRI Madiun compulsory courses logic and set. This paper discusses the stages and the weakness of the student reasoning in the logical thinking with the set. Based on the results of a descriptive research-qualitative study program conducted in mathematics education earned the stages and the weakness of the reasoning of the students in the logical thinking with the set. Stages of reasoning of the students in the logical thinking with the set as a means of visualization are: 1) Connect each set with the premise, 2) Connect both premises and pay attention to the possibilities of possible illicit; and 3) paying attention to both possibilities as the basis for the with draw of the conclusion. Weaknesses of student reasoning in logical thinking with the set as visualization are: 1) Students see problems separately and have not been able to connect with the conclusion or the premise of the set that's been studied; 2) Students can already connect to the problems with the concept of the set but haven't been able to connect between premise; 3) Students can already connect the premise to the concept of set, but less thorough so as to give an answer that is less precise; and 4) Students can already connect to premise by the concept of the set and had a thorough look at all the possibilities so as to provide an answer with precision.

Abstract

Most in learning mathematics in Indonesia, students are familiarized with the write-down is known, asked, and the answer to resolving the issue. Conditioning is different from the theories of problem-solving, such as Polya provide problem resolution with understand, plan, implement, and re-evaluate it (looking backward). The difference between theory and practice applied mainly drew attention in the study of logic and the set. Results of the study indicate that there are two modes of representation of problem solving in Indonesia. The first model of mathematical problem solving is writing the note, asked, and answered. The second model is the solution to math problems in Indonesia is taking the example, will be demonstrated, and evidence.
