Estratégias para adoção das redes experimentais no ensino de redes de computadores: dispositivos para orientação docente

Abstract

In an attempt to promote active, dynamic and student-centered learning, several institutions have invested in the use of simulators, games, virtual laboratories, and more recently experimental network environments (testbeds) as a technological alternative for carrying out practical laboratories. Testbeds have been used as platforms to support the development of research in the area of ​​networks for some time, and it is common that over time the technologies used in their construction consolidate and become popular with the community, enabling the expansion of the its use in other areas, in addition to research techniques, and it is precisely in this scenario that there is an opportunity to use these environments in education. However, even with the advantages of providing differentiated training to students, since tests on testbeds are carried out with real equipment, their use in teaching is still low, since there is no system that guides teachers in the use of these environments. to enhance the teaching and learning process for students, there are no assessment techniques that consider their specificities. In this sense, in this dissertation we present two products: the RUBIK evaluation device, created to allow the evaluation of courses that use test banks from different perspectives and a Recommendation Guide with basic recommendations to guide teachers in the insertion of test banks in the classroom. of class. The objective of RUBIK is to evaluate the effectiveness of testbeds in teaching computer networks, as well as to become a generic tool for evaluating courses that use these environments as technological infrastructure for carrying out practical laboratories. The guide aims to contribute to the process of adopting testbeds in the classroom, thus expanding students' learning opportunities, based on the application of theoretical concepts in practical situations. Thus, the resources presented in this dissertation (RUBIK and Recommendations Guide) suggested to support the teacher by signaling important criteria to be considered from the elaboration phase to the effective evaluation of courses that use test banks as technological infrastructure to carry out practical laboratories.
