Previous issue date: 2018-03-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / This research contains information on four collections of textbooks of the Chemical component approved in the PNLD of 2015 address the chemical knowledge, promoting requisites for the formation of mental representations, in Peirce (1974), and avoiding epistemological obstacles, in Bachelard. For this analysis, chapters of Chemical Reactions, Chemical Kinetics and Alcohol function were selected as sources of texts for the investigation, due to the importance of this knowledge for the academic level of Basic Education. The texts were analyzed qualitatively, relating the main characteristics of the essays of the chapters with the theoretical assumptions that guided the investigation. With respect to the approach of aspects of chemical knowledge and mental representations, the analysis aimed to understand convergent characteristics in the writing of the texts with the theory of Jonhstone, assumptions of Mortimer and the semiotic theory of Peirce. With regard to the epistemological obstacles, tables were built to identify and categorize the impediments identified in the texts. With the end of the analysis, it was understood that the books do not have the same properties regarding the ways of approaching chemical knowledge, and most of the texts presented deficiencies in relation to the phenomenological approach. Regarding mental representations, most of the books did not demonstrate adequate characteristics, mainly related to the First level, initial stage for the formation of a mental representation. Regarding the epistemological obstacles, a small quantity was identified, not having any relevance to impair the learning of the chemical knowledge present in the textbooks. / Esta pesquisa teve por objetivo compreender como as quatro cole??es de livros did?ticos do componente Qu?mica aprovados no PNLD de 2015 abordam os conhecimentos qu?micos, na perspectiva de Johnstone (1993) e Mortimer, Machado e Romanelli (2000), como promovem requisitos para forma??o de representa??es mentais, em Peirce (1974), e como se comportam em rela??o aos obst?culos epistemol?gicos, em Bachelard (1996). Para esta an?lise, foram selecionados cap?tulos de Rea??es Qu?micas, Cin?tica Qu?mica e Fun??o ?lcool como fontes de textos para a investiga??o, devido ? import?ncia desses conhecimentos para o n?vel acad?mico da Educa??o B?sica. Os textos foram analisados qualitativamente, relacionando as principais caracter?sticas das reda??es dos cap?tulos com os pressupostos te?ricos que orientam a investiga??o. Por meio da an?lise empreendida, conclui-se que as obras n?o possuem as mesmas propriedades referentes aos modos de abordar os conhecimentos qu?micos, tendo a maioria dos textos apresentados defici?ncias em rela??o ? abordagem fenomenol?gica. Sobre as representa??es mentais, grande parte dos livros n?o demonstraram caracter?sticas adequadas, principalmente relacionadas com a primeiridade, est?gio inicial para a forma??o de uma representa??o mental. Referentes aos obst?culos epistemol?gicos, uma quantidade pouco significativa foi identificada, n?o tendo relev?ncia em rela??o ? aprendizagem dos conhecimentos qu?micos presentes nos livros did?ticos.
