Abstract
This study provides a taxonomy of prominent opportunities and challenges yielded by utilizing gamification and serious games for English language learning. A Delphi method is used to gather computer science students' opinions resulting from a SWOT analysis of the use of these two different game-based ways to learn English language. This study produced an ordered list of important adoption and entry issues to consider when gamifying the English language learning experience. Additional factors were identified through a discussion of these issues. Based on our findings, we further discuss the relevance and implications of opportunities and challenges associated with gamification and serious games.
