This is an impactful contributions, methodological rigor, and exceptional novelty in the research field of AI in education.
Our publication „Synthetic Educators: Analyzing AI-Driven Avatars in Digital Learning Environments“ at this year’s HCII conference is published.
Abstract:
Videos can be used in a variety of ways in learning environments today. With advances in generative AI technologies, tools such as HeyGen and ElevenLabs make it easy to create synthetic teachers, promising efficiency and accessibility. This study investigates the impact of AI-generated teaching video avatars on learners‘ emotional responses. A mixed-method approach was adopted, in which 55 participants were shown AI-generated videos and videos with real instructors. Emotional engagement was measured using FaceReader Online, along with quiz questions and follow-up interviews to gauge knowledge retention and perceptions of this educational technology. Results indicate that AI avatars effectively convey content and weakly elicit better recall rates and positive emotional responses comparable to those of real instructors. However, concerns were raised about emotional authenticity and engagement, highlighting the need for improved avatar design. The study concludes with a discussion of the potential and limitations of AI avatars and argues for their thoughtful integration to improve educational equity and learning outcomes.
