O-Learning TVDi :um framework de TV digital interativa para manipular objetos digitais de aprendizagem relacionados ao ensino da trigonometria

Abstract

The development and reuse of software architecture oriented education in Brazil are still in need of research to reduce the time, cost and better utilization of the features that meet the pedagogical features in a real environment for learning. This dissertation explores the features of object orientation to define an architecture framework for interactive Digital TV and reuse the functionality of the modules digital learning objects. With the need to focus on a specific type of problem, which identifies students in high school and college still have difficulties in learning mathematics, therefore investigates the field of trigonometry in order to promote entertainment and education on ways of teaching resources used by teachers. It is part of this dissertation also investigate applications and middleware frameworks developed by the Digital TV standard in Europe and Brazil, highlighting difficulties such as definition of standard interfaces, handling graphics, audio and video resources. To qualify the system evaluation results generated are presented in three classes using the resources of learning objects for teaching trigonometry in a digital television system. The results obtained in the experiment show that the environment contributes positively as a further support of technological resources that can be used in education and promotes the need to use free applications for interactive digital TV, leaving an architecture that can be exploited for other field of or other mathematical discipline using the same methodology.
