This chapter belongs to the context of the computer-mediated communication (CMC) for language teaching and learning. Since the introduction of this new communication method, new paths for the teaching and learning of languages have been opened. In this research, virtual discussions in the English language about polemical topics were carried out through the use of the AMANDA program. This program features artificial intelligence principles in the discussion coordination, diminishing the tutor’s workload in the task of coordinating the discussions. The goal of this research was to observe the contributions of the CMC tool for the learning of English by the participating students. In total, 83 upper-intermediate English level students took part. The analyses and final considerations concentrate on the evaluation of the program used as well as the positive and negative aspects observed during this research for the teaching/learning of the English language.
