Formal ?spat?n Mevcut Olmad??? Bir Durumda ?spat ?maj? Var Olabilir Mi?: Ba?ar?s?z Bir ?spat Giri?iminin Analizi

As proof and proving are the key elements of mathematics, several frameworks evaluating this process have been presented. Proof image, being one them, was introduced by Kidron Dreyfus (2014) through analyses two mathematicians' activities. Authors clarified it in context components, emphasized its relation with formal proof. However, despite mentioning possibility, they didn’t present any case where image exists without This led us investigating dynamics such cases. Multi-stage sampling preferred, 120 pre-service teachers were asked to prove theorems about algebra firstly. Then, task-based interviews conducted 3 participants, who proved both theorems. Moment-by-moment sub-dimensions discussed detail. Additionally, role “enlightenment” reinterpreted feeling dimension elaborated. Consequently, identified that participant had an although she couldn’t reach proof, her story
