THE MULTIMODAL LEARNING AS A STRATEGY FOR CHEMISTRY REPRESENTATIONS CONVERSION: THE PHENOMENON TO THE CHART

Go through multiple ways of representation constitutes an essential skill to recognize, understand and explain numerous phenomena on the natural sciences and simultaneously relating them to the social and technological aspects that permeate the contemporary society. This integration of meanings becomes particularly relevant when the forms of representation are Cartesian systems, which add, among others, opportunities to build inferences and predictions during its production or reading. The learning that focuses the movement between these multiple forms of representation is not innate and dependent on teaching strategies that provide and encourage this practice. Learning strategies that consider aspects that combine multimodal oral narratives, texts and numbers, visual and audiovisual language are powerful tools that are available to be inserted into instructions in chemistry classrooms. These strategies allow the teacher to establish the initial skills and their evolution throughout the process regarding the ability of students to construct graphs representing the phenomena studied in the conceptual and analytical perspective. In this work are presented and discussed the results of evolution in the form of representation of Cartesian graphs for high school students before and during the process of multimodal learning. At the beginning of the process the students build their charts showing only a superficial view of the subject, merely just plot the data between two axes. Throughout the process students moves from a practical copyist to an explicit vision essential to a practice in which the relationships and conceptual analytical view about the phenomenon are considered.
