The evolution of adaptive Artificial Intelligence (AI) agents within e-learning plat- forms continues to be pervasive, but little is known about how user awareness of the system can change perception or behaviour. This thesis puts forth the notion that awareness of an AI agent system within an e-learning system can affect learning out- comes. Using a flashcard-based website with an adaptive AI agent, participants were placed in either an unaware Control group or a Test group who were aware of how the AI agent worked. Participants were tested on their Spanish understanding before and after using the website, as well as other factors. The results indicate that those who were aware of the AI system had worse learning outcomes compared to the un- aware group. The results suggest that there can be changes in user learning based on awareness of a system's adaptive AI agent.
