Abstract

The purpose of this research is to elaborate and describe the student error in proving
mathematical statements using mathematical induction and their cause. The method of
this research is descriptive with case study. The research subject are the student of class
XI MIA SMA Islam BAWARI Pontianak. Data collection tools used diagnostic tests and
interviews. Based on the data analysis, the errors under taken by student consisted of
three types of errors, namely conceptual errors, procedural errors and technical errors.
Of the three types of errors, the most common is procedural errors. The causea of
student errors are that students are fixated on the sample questions given, students don"™t
understand the principle of mathematical induction, the nature of multiplication of
exponents, as well as meaning and use of the assumption n = k is true. In addition,
student also don"™t understand what statements are proving in the induction step, the
procedure for proving the n=k+1 and manipulate algebraic expressions in the induction
step. There is no explanation during the online learning process so that students cannot
solve problems. Students are in a hurry when writing answer from the scribble sheet to
the answer sheet.
