Opinions Of High School Students About Mathematical Proof.https://hdl.handle.net/20.500.12604/2328This study aims to discover the varied opinions of high school students about proof and mathematical proving. Accordingly, the research is carried out on 136 high school students studying at all grades of in a high school in the Erzurum during 2014-2015 academic year. Data were collected and prepared by researchers in the three open-ended questions with data collection tool. This data of the research are collected by taking written answers to the questions posed to students. As a result of the study, students generally define the proof as "explanation" and "reality". At the same time, most of the students comprehend making a proof as "understanding the accuracy or inaccuracy" and "explaining". And finally, students define making a mathematical proof as "verifying" and "showing the result of the operation". Moreover, opinions of high school students are evaluated and discussed according to grades.trinfo:eu-repo/semantics/openAccessMathematical proof,mathematics educationhigh school studentsArticleSpecial Issue428434
