| Summary: | nÃo hà === A pesquisa desenvolvida teve como objetivo contribuir com o ensino-aprendizagem da QuÃmica, oferecendo elementos ao professor que possam facilitar e auxiliar na elaboraÃÃo do conhecimento sobre a evoluÃÃo dos modelos atÃmicos. Desenvolveu-se o estudo com alunos do 2 ano mÃdio do ColÃgio Estadual Celso Alves de AraÃjo, da cidade de Cedro, Estado do CearÃ, com os quais foram discutidas as propostas apresentadas, apÃs uma reflexÃo, mediada pelo professor, tendo sido evidenciada a maneira como os alunos concebem os conceitos submicroscÃpicos. Desde entÃo, a estratÃgia sugerida foi a fundamentada no uso de imagens para facilitar e estimular a retenÃÃo do que foi aprendido. Procurou-se detectar e discutir as concepÃÃes mais relevantes acerca dos conceitos envolvendo o tema EvoluÃÃo dos Modelos AtÃmicos, buscando analisar as maiores dificuldades sentidas com origem nas concepÃÃes detectadas e desenvolver uma proposta de estratÃgias de ensino-aprendizagem dos referidos conceitos, com uso de novas mÃdias. Desenvolveu-se, colaborativamente, uma aula sobre a EvoluÃÃo dos Modelos AtÃmicos, usando o software Visual Class. A realizaÃÃo deste trabalho aumentou a motivaÃÃo dos alunos, pois demandou da parte deles estudos e pesquisa mais aprofundados acerca do assunto. Ficou constatado, pelo uso de mapas conceituais, que as informaÃÃes recebidas por eles se transformaram em aprendizado, mais eficientemente do que quando essas mesmas informaÃÃes foram repassadas de maneira tradicional. === We have searched to detect and discuss the most relevant conceptions, that the students from high school second grade about the conceptions involving the theme Evolution of the Atomic Models, searching to analyze the greater difficulties felt from the detected conceptions and develop a proposal of teaching-learning strategies of the referred concepts, with the use of new media. We have developed the study of this research-action with students from the high school second grade of Celso Alves de AraÃjo State School, from Cedro City, CE, with which the presented proposals were discussed, after a process of reflection, mediated by the teacher, it was evidenced the manner in which students conceive the submicroscopic concepts. From then, the suggested strategy was the one based on the use of images in order to facilitate and stimulate the retention of what was learned, since the image activates several brain abilities which stimulate and promote the creative thinking, helping thus on the memorization, since It has been proved that images are more memorable than words. We have developed collaboratively a class about the Evolution of Atomic Models using the software Visual Class, since it counts on the easiness of being able to be used without programming previous knowledge. The accomplishment of this task increased a lot the students‟ motivation, because they could express the studied concepts, in such a manner closer to their sensitiveness, since it demanded from them a deeper study and research on the subject. It was verified, through the use of conceptual maps, that the information received by them turned into more effective learning than when this same information are passed traditionally.
