In the context of Science Education, the conceptions of Paulo Freire and Lev S. Vigotski have contributed individually to the shaping of new perspectives of analysis and theory of scientific knowledge that is produced and incorporated by individuals. This theoretical study indicates that on one hand Freire and Vigotski' ideas converge in three aspects: a) valorization of daily knowledge; b) similarities between the role of specialists in Freire and the role of more able individuals in Vigotski and c) awareness. On the other hand, the scholar's ideas diverge in two aspects: the knowledge genesis and b) the starting point of learning process. Moreover, the possible complementarity of both Freire and Vigotski's ideas may improve curricular proposals in Science Education.
