The study and interest of figurate numbers can be observed even in ancient Greece. On the other hand, it becomes very important the historical understanding about an evolutionary process and the particular generalization of such 2D, 3D and m-D figurate numbers and they remain the interest of current scientific investigations. On the other hand, in…

Alves, Francisco Regis Vieira; Silva Camilo, Aline Maria da; Fontenele, Francisca Cláudia Fernandes; Catarino, Paula Maria Machado Cruz – Acta Didactica Napocensia, 2021
This work presents a discussion about the Didactic Training Engineering (EDF) methodology, of French origin, emphasizing the role of the teacher, during his initial or continuous training, through the conception and structuring of a didactic situation, organized by such methodology and based on the Theory of Didactic Situations (TSD). Therefore,…

Méxas, José Geraldo Franco; Bastos Guedes, Karla; da Silva Tavares, Ronaldo – International Association for Development of the Information Society, 2014
The representation of figures in mongean projection (double system planned orthographic projection used in the studies of Descriptive Geometry), specially when placed in a particular situation in relation to the projection plans, possesses the quality that, through them, the actual dimensions of represented spatial objects can be found directly…

Borba, Marcelo C. – International Group for the Psychology of Mathematics Education, 2005
This paper presents some research findings regarding the changes in the mathematics produced by mathematics teachers in on-line distance courses. Predicated on the belief that knowledge is generated by collectives of humans-with-media, and that different technologies modify the nature of the knowledge generated, we have sought to understand how…
