Daftar Isi:
  • This study aims to analyze the location of students' errors in problem solving and the causal factors based on Watson's criteria. This type of qualitative descriptive research, with the subject of three students of class X AKL 1 taken based on certain considerations according to the criteria or can be called purposive sampling technique. Data collection techniques include direct observation in schools, interviews with subjects and documentation. Triangulation techniques used for data analysis include data reduction, presentation and conclusion drawing. From the results of the analysis, it was found that four types of errors were located inimproper procedures, indirect manipulation, missing data and missing conclusions. The cause of the error is students lack understanding of material concepts, being careless in reading questions, forgetting formulas, being in a hurry, and new factors are found, namely students use other paper to write down the completion steps. The results of the study can explain in detail the errors made by students in solving problems, so that it can minimize the occurrence of similar errors and improve the learning process of mathematics.
  • Penelitian bertujuan menganalisa letak kesalahan siswa dalam penyelesaian soal serta faktor penyebabnya berdasarkan kriteria Watson. Jenis penelitian deskriptif kualitatif, dengan subjek tiga siswa kelas X AKL 1 yang diambil berdasarkan pertimbangan tertentu sesuai kriteria atau bisa disebut teknik purposive sampling. Teknik pengumpulan data meliputi observasi secara langsung disekolah, wawancara terhadap subjek serta dokumentasi. Triangulasi teknik digunakan untuk analisis data meliputi reduksi data, penyajian dan penarikan kesimpulan. Dari hasil analisis ditemukan empat jenis kesalahan terletak pada prosedur tidak tepat,  manipulasi tidak langsung, data hilang dan kesimpulan hilang. Penyebab kesalahan yaitu siswa kurangnya pemahaman terhadap konsep materi, kurang teliti dalam membaca soal, lupa rumus, terburu-buru, dan ditemukan faktor baru yaitu siswa menggunakan kertas lain untuk menuliskan langkah-langkah penyelesaian. Hasil penelitian dapat menjelaskan secara rinci kesalahan yang sering dilakukan siswa dalam penyelesaian soal, sehingga dengan ini dapat meminimalisir terjadinya kesalahan serupa dan dapat memperbaiki proses pembelajaran matematika.
