摘要：One of the most important aims of mathematics instruction is to ensure the development of obtaining logical answers to "why" and "what for" questions, that is to say, the development of reasoning (Alt.parmak & .zi., 2005). For the mathematics instruction to achieve this aim, mathematical proofs constitute an important tool in terms of dealing with not only the correctness of a statement but also why it is correct. Mathematical proofs are regarded as the most important factor in learning mathematics because they involve associating judgments in a certain mold and being sure of these judgments in view of the development of mathematics and realities or propositions (Knuth, 2002).
