Abstract

Penelitian ini bertujuan untuk mengetahui bentuk-bentuk kesulitan siswa dalam menyelesaikan soal relasi berdasarkan kriteria Certainty of Response Index (CRI) yaitu siswa yang tidak paham konsep (lucky guess), tidak paham konsep (a lack of knowlegde) dan miskonsepsi. Penelitian diskriptif kualitatif ini menggunakan metode tes dan wawancara untuk memperoleh data bentuk kesulitan, siswa sebagai subjek penelitian adalah siswa kelas VIII yang telah mempelajari materi relasi. Hasil penelitian menunjukan bahwa sesuai kriteria CRI, tentang paham konsep lucky guess terdapat 11 kesulitan, terdapat 10 kesulitan pada bentuk paham konsep namun menebak dan tentang miskonsepsi terdapat 14 jenis kesulitan. Jenis kesulitan dalam memahami prinsip, kriteria CRI paham konsep (lucky guess) terdapat 9 kesulitan, pada kriteria paham konsep namun menebak (a lack of knowlegde) terdapat 9 kesulitan dan kategori miskonsepsi terdapat 18 kesulitan

Abstract

This research aims to find out the misconceptions of students about the concept of the set using certainty of response index (CRI) indicators. The research subjects consisted of 89 students who programmed the Introduction to Basic Mathematics (PDM) course. The research method used is qualitative descriptive. A written test consisting of 4 reasoned multiple choice and descriptive questions were used to collect research data. The results showed that based on CRI criteria, for problem number 1 about the differences of set and not sets, there were 39% of students experiencing misconceptions, 33% of students do not know the concept and 28% of students who know the concept correctly. In question number 2, the questions about three ways of presenting a set of natural, whole, prime and integers numbers, it was found that 12% of students experienced misconceptions and 76% of students did not know the concept because of guessing and lack of knowledge, the remaining 11% of students understand the concept very well. For problem number 3, about the operation of the set found that 30% of students experienced misconceptions, 45% did not know the concept and the remaining 24% understood the concept correctly. Furthermore, for problem number 4, the set operation story was obtained the result that of 19% of students who took the test experienced misconceptions, 57% of students did not understand the concept and only 24% of students understood the concept correctly. In other words, of the 4 questions that were tested on students, questions number 1 and 3 were mostly found by students experiencing misconceptions. Although problem number 2, it was found that at least students experienced misconspection but in this questions almost 80% of students did not know the concept correctly
