Persepsi Mahasiswa Dalam Memvalidasi Bukti Matematis

Abstract

This study aims to describe the perceptions of prospective students in the first year in validating mathematical proof. This student's perception is discussed based on the answers given to the proof of a theorem. This research is a qualitative research. The subjects in this study were three students from the second semester mathematics education study program at a university in East Java. Research subjects were chosen deliberately with the following considerations: prospective teacher students who use examples in making mathematical proof and good communication skills make research can facilitate students' perceptions in writing mathematical proof. The results showed that students had perceptions about who gave several examples so that the proof was called valid, one example of denying it could prove it was invalid and using formal proof that proved it could be proven valid

An analysis of the difficulty of prospective mathematics teachers on algebraic materials

“…Prospective mathematics teachers often make mistakes in proving a mathematical statement by giving certain examples (Herutomo, 2019). Prospective mathematics teachers consider providing relevant examples to validate the proof (Matitaputty, 2020). This difficulty is caused by a lack of practice working on mathematical proof problems (Sulfiah et al, 2020).…”
