Chapter 3 DOI: 10.4018/978-1-5225-2426-7.ch003 ABSTRACT Use of virtual worlds in education can be exploited in diferent educational topics through use of simula- tions, 3D objects, multimedia resources and educational activities that seek to assist student’s learning. For the realization of these activities, it is necessary to adopt an educational foundation that seeks to guide the processes described. Therefore, this chapter sought to explore the use of virtual worlds with educational theory Mastery Learning, in which the learning activities and educational planning ad- opted were based on the principles described in this theory. A case of study was applied with a group of students of a discipline of programming and algorithms to show the feasibility of this proposal and explain to readers the particularities of implementation in this integration. Results obtained from this experiment were considered valid and instigators in the middle of the evaluations were positive, and the comments made by students helped to identify a number of difculties that arose during the experiment. INTRODUCTION Expansion use of Information and Communication Technologies (ICT) in the educational field has been proliferated in several areas of education, in which, researchers and teachers have sought to add educa- tional methodologies to the technological resources available in order to improve processes of student’s A Perspective on the Application of Mastery Learning Theory in Virtual Worlds Felipe Becker Nunes Federal University of Rio Grande do Sul, Brazil Fabrício Herpich Federal University of Rio Grande do Sul, Brazil Maria Angélica Figueiredo Oliveira Federal University of Rio Grande do Sul, Brazil Kelly Hannel Federal University of Rio Grande do Sul, Brazil Maria Lucia Pozzatti Flores Federal University of Pampa – Caçapava do Sul,, Brazil José Valdeni de Lima Federal University of Rio Grande do Sul, Brazil
