Uma imagem vale mais com mil palavras : estudo sobre a produção de textos multimodais para o ensino do conceito de respiração pulmonar

Abstract

In today's language, several semiotic modes (verbal, visual, sonorous and gestural, among others) are integrated to construct a meaning, thus composing a multimodal text that together with advances in technology occupy more spaces each day, and among them, the space of teaching and learning of sciences. However, although there is a growing use of multimodal text, it is still not being exploited to its full potential, as teachers are often not instrumental in reading to understand and produce. Above all, in considering the eminently abstract and symbolic character of its contents, the initial formation of science teachers demands the reading and production of more contextualized multimodal texts that can generate effective and qualified actions in the teaching practice regarding the use of different modes of language. In this context, the objective of this study was to analyze how the knowledge about Multimodality inserted in the initial formation of teachers can contribute to the reading and the construction of multimodal texts for teaching about human lung breathing. In the course of this research the elective Multimodality in Science Education course was developed, offered for the undergraduate courses in Chemistry and Biological Sciences, of a Brazilian public university. The data were constructed during 11 months of work incorporated to this discipline, with a group composed by four students. The methodology that guided the present study was an adaptation of the Collaborative Research (IBIAPINA, 2008) and the data analysis employed the categories of Visual Design Grammar (KRESS and van LEEUWEN, 2006). The productions of the analyzed students were: multimodal texts produced for videotapes on pulmonary respiration; answers to the interview about the process of videotape production; video-recorded analysis of the multimodal texts related to the respiratory system and hematose used in videotapes; production of the Set of Multimodal Texts for Teaching Human Pulmonary Respiration (CTMER) and validation of CTMER in class at graduation. At the same time, the researcher analyzed the multimodal texts on lung breathing in the textbooks. The results indicate that the implementation of Multimodality knowledge in reading, evaluation and production of multimodal texts increased the capacity of representation and communication of the participants involved through the integrated use of different modes of language and enabled the construction of didactic material (CTMER) to teach the concept of human lung respiration integrated with the environment and other organic systems.
