ALMOULOUD, Saddo Ag. As transformações do saber científico ao saber ensinado: o caso do logaritmo. Educ. Rev. [online]. 2011, n.numeroespecial, pp.191-210. ISSN 0104-4060.

In order to teach a scientific concept at a given school level, this concept must be accessible to the students; therefore, it must be transformed based on a reference knowledge, which is, in general, the knowledge from the discipline's specialists (scholar knowledge). In this paper, theoretical tools from the didactic of Mathematics are presented to study the transformation of scientific knowledge into taught knowledge. The mathematical object on focus is the "logarithm." The logarithm function is one of the most important concepts in the High School curriculum. It has various applications in a wide range of knowledge areas, such as physics, chemistry, economics, astronomy, justifying its continued inclusion in the curricula proposals of various countries.
