FLOREZ, Camilo Sua. Knowing Enough Is Not Enough: Metacognitive Behaviors When Solving Proof Problems with the Support of Dynamic Geometry. Rev. Fac. Cienc. Tecnol. [online]. 2019, n.45, pp.121-142. ISSN 0121-3814.

Proof problems demand to put into play different knowledge and instrumental skills when it is supported by dynamic geometry. However, as we show in this paper, an individual's set of knowledge and the degree of instrumentalization of the software are not the only relevant aspects in the resolution process or in the nature of the response obtained. Supported in two groups of mathematics pre-service teacher with a different level of mathematical training, we show that metacognitive aspects such as control, regulation and evaluation of executed actions become elements that can lead to a group, with mathematical knowledge reduced, to obtain better results than a group with a deep knowledge of the discipline. We show how group work and the use of dynamic geometry have a positive effect on the resolution process and promote metacognitive aspects.

Keywords : problem solving; dynamic geometry; metacognition; proof problems.
