JUNIOR, Niltom Vieira  e  COLVARA, Laurence Duarte. Mental models of vectors in two and three dimensions: analysis of the learning dynamics and the inadequacy of traditional evaluation. Ciênc. cogn. [online]. 2010, vol.15, n.2, pp.55-69. ISSN 1806-5821.

Abstract This work presents an investigation with students from Federal Institute of Minas Gerais (IFMG) - Campus Formiga. After identifying the thinking strategies and the students difficulties to deal with vectors in two and three dimensions, through mental models, it was found that not always the system of beliefs from teachers match with that one from students. Then this paper shows that the traditional methods of evaluation, sometimes, may not mensure the level of students and the teaching methodologies may also be in disagreement with the need of students. Here were used interviews and analysis of conceptual maps developed by the students. So, are present here the mental models of vectors in two and three dimensions, to allow interventions more precise in science teaching. © Cien. Cogn. 2010; Vol. 15 (2): 055-069.

Palavras-chave : mental models; vector representation; science and math education.
