Proper, improper and apparent fractions: an analysis of the Visual Grammar of MathLibras videos
Year: 2024
Type: article
Abstract: The objective of this article is to analyze three videos about fractions from MathLibras, based on the Visual Grammar proposed by Rosado and Taveira (2022). The project MathLibras produces videos that provide Mathematical contents in Libras. The theoretical framework of the videos' analysis is the Visual Grammar for the digital videos in sign languages, which is a description and planning proposal for video's production. This proposal presents seven basic constituent elements that can be analyzed on a frame that is captured. The results indicate that the videos maintain a standard opening, closing and dressing; the captions are optional; there is audio insertion; it is ensured that the number of elements on screen is not excessive and that the images used in the videos are structured to help visualize the concepts. It is suggested that Mathematics videos in Libras can be produced respecting the specificities of Visual Grammar.
