Épura ao vídeo: desenvolvimento e uso de um aplicativo para o trabalho com geometria descritiva

Abstract

The learning process of introductory studies, the orthogonal projective system and constituent elements (point, line and plane), used in Geometry for high school students in technical training courses makes it difficult to develop spatial vision and graphic representation. Learning to see allows the student to understand the formation of projections and return to the practice of observation. Three-dimensional visualization produces recognition of the projected image. The development of this learning cannot be restricted to study based only on programmed handouts with forms or feedback solutions.This Design-Based Research developed and implemented a system of security cameras to aid in visualization. This innovation provided for the construction of an educational experience that fosters collaborative learning through interaction with three-dimensional models of the objects to be represented in graphic drawings. The proposal to investigate the practice of graphic representation and strategies for development of this graphic language was carried out with students, aged between 14 and 17 years, in high school at a state technical school. Data collection was done by the researcher in research logs, activities proposed in class and recordings from security cameras positioned to capture the image Épura. Results underline the importance of creating an educational process applied to technical drawing that develops the act of the careful observation and integration of objects and images with the main aspects of projective drawing. This enables the learning of the concepts of descriptive geometry and facilitates the visualization of the trihedral system and the design of the principal orthographic views (front, top and side) utilizing varied teaching strategies
