Pre-service mathematics teachers’ views about proof by using concept maps

Although the proof is one of the basic concepts in mathematics, students have difficulty to use mathematical proof in advanced mathematical courses. Even students who take a number of university level advanced mathematics courses are not able to grasp the mathematical proof. Accordingly, the purpose of this study is to investigate what pre-service mathematics teachers understand about the proof. In this case study, 22 pre-service mathematics teachers are involve in a brain storming activity. The number of terms appeared after this activity is 21. It is also found that they could not appropriately relate these terms in their concept maps.
