Abstract

Penelitian ini bertujuan untuk mengidentifikasi kesalahan siswa dalam menyelesaikan soal persamaan kuadrat di SMA Negeri 2 Kota Sorong. Menggunakan metode kuantitatif dengan teknik pemilihan sampel acak, 31 siswa kelas XI dianalisis menggunakan statistik deskriptif. Selain itu, wawancara dengan lima siswa dilakukan untuk mengetahui alasan di balik kesalahan mereka. Hasil penelitian menunjukkan bahwa kesalahan paling umum adalah tidak menyelesaikan soal (29%), diikuti oleh kesalahan dalam memahami soal (28%), dan tidak menjawab soal (22%), dengan kesalahan tidak melanjutkan proses sebagai yang paling jarang terjadi (21%). Wawancara mengungkapkan bahwa kesalahan ini sering disebabkan oleh kurangnya pemahaman konsep dan kesulitan dalam menerapkan rumus. Kesimpulannya, diperlukan peningkatan metode pengajaran dan pemahaman konsep siswa untuk mengurangi kesalahan-kesalahan tersebut.

Abstract

This study aims to identify the types and factors of errors made by students in the Mathematics Education Program at Universitas Muhammadiyah Sorong when solving problems related to mode, median, and mean, which are part of statistical methods material. This research employs a qualitative descriptive approach, involving six students from the Mathematics Education program who made the most errors. Data were collected through written tests completed by these six subjects. The data analysis technique involved examining answer sheets, scoring each question, presenting the percentage data for each type of error, and drawing conclusions. Based on the entire analysis, it was found that the types of errors in calculations were 22%, errors in the use of formulas were 28%, and errors in determining the total frequency were 6%. The factors contributing to these errors include a lack of accuracy in calculations and difficulty in finding the correct formulas. The conclusion of this study is that students frequently make errors in solving mode, median, and mean problems, particularly in understanding the material, using formulas, and producing the final answer
