Analisis Kesalahan, Matematika, TrigonometriAbstrak
Penelitian ini betujuan untuk mendapatkan deskripsi analisis kesalahan soal trigonometri yang dianggap sulit oleh siswa Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif yang bertujuan untuk mengetahui dan mendeskripsikan penyebab kesalahan siswa dalam menyelesaikan soal trigonometri. Subjek dari penelitian ini adalah siswa SMK Kelas XI IOP B di Kota Cimahi yang sudah mengampu mata pelajaran Trigonometri, dari 33 siswa diambil 3 jawaban siswa sebagai sampel yang dapat dianalisis hasil jawabannya. Intrumen yang digunakan dalam penelitian ini berupa tes yang terdiri atas 5 butir soal. Berdasarkan tes uji soal terhadap siswa kesalahan yang dibuat oleh siswa ketika menjawab soal adalah kesalahan dalam menentukan perbandingan trigonometri, kesalahan dalam menentukan langkah penyelesaian, kesalahan dalam menentukan panjang sisi-sisi segitiga dan tidak membuat kesimpulan jawaban.
ABSTRACT
This research aims to obtain the description of error analysis in solving trigonometric problem that is considered difficult by students. The method in this research was descriptive qualitative which aimed to find out and described the causes of student errors in solving trigonometric problems. The subjects of this research were students of Class XI IOP B Vocational School in Cimahi who had mastered Trigonometry, from 33 students taken 3 student answers as samples that could be analyzed the results of the answers. The instruments that used in this research were test instrument consisting of 5 questions. Based on the test of students' questions the mistakes made by students when answering questions are errors in determining trigonometric comparisons, errors in determining the completion step, errors in determining the length of the sides of the triangle and not making conclusions on the answers.
