The subject venomous snakes is pointed out as a problem in science education textbooks in Brazil, due to the high rate of conceptual mistakes. Aiming to help teachers in that subject, we analyzed a total of 27 textbooks published in the period 1982 to 1999. The criteria used in the conceptual analysis were based scientific correction and the presence of non-scientific classification. In relation to the conceptual analysis, data collected showed predominance of problems related to the biology of snakes, identification and differentiation among venomous and non-venomous ones, incorrect self-care instructions, inappropriate attendance care in case of venomous’ snakes accident, besides the use of anthropocentric concepts. Data collected showed also that in most of the textbooks problematization and contextualization are not considered in despite of the descriptive form, predominant citation of the animal’s anatomical data, nomenclature and definitions. Proportionally, it was found higher number of problems in science textbooks than in those destined to high school biology.Downloads
