Recent researches suggest that quite frequently science teachers perspectives about the nature of science and on scientific knowledge construction are inadequate. Researches also suggest that such inadequate perspectives may influence through science teaching the images held by students about the nature of science and of the scientific knowledge. This paper presents the main features of seven teachers' perspectives with an extensive review of related research studies. Alternative views based on pos-positivist frameworks are then outlined as well as their implications for science teaching.
