RESUMO

A detailed search for digital programs applied to teaching processes was performed to identify the available resources on the world market. It was also carried out a survey on public and private libraries looking for the requirements of the academic community regarding computational resources to such purpose. It was found that although considered important, there were few alternatives for the development of virtual classes that demands little operational effort as well as a simplified infrastructure for its use. The goal of this work is to develop and assess a system - VirtuAula - to assemble and present on-line and off-line virtual classes, requiring low experience on informatics for its users as well as being adequate to common resources available in universities. The basic functional requirements defined for developing the VirtuAula were a standard interface, which means identical browse for all operations, a user-friendly help desk and the possibility to use already prepared slide shows and texts. Two work platforms were elaborated, one for teachers, which allow them to create, change and carry out the virtual class, and a second platform for students to attend this virtual class. For the system assessment two tests plans were used; standard tools as the Evaluation Criteria of the Software Quality (grading method), and questionnaires that were filled by the involved teachers and students. The off-line classes reached the maximum grading score in all the evaluation topics, while on-line classes reached an average score over 1,78 (in a 0-2 scale). All the involved teachers answered that they would like to carry out virtual classes using this system; 75% declared that they would like to use it for their work, and 25% declared that they could use it. Among the students, only 2,33% dislike the virtual classes using the VirtuAula while 4,65% informed that they would not like to have such kind of classes in their courses. Looking for the reas ons for the lower performance of on-line classes in this survey, the major cause was the difficulty to carry out such event on the present commercial Internet system due to its low performance during very heavy data transfer. Among the conclusions presented here, it can be depicted that the system is an interesting alternative tool for public schools in Brazil due to its originality (no similar software), low cost and user free possibility.
