Özet
This study examines the impacts of educational videos with human or humanoid animated pedagogical avatars (APAs) on cognitive, affective, and social learning outcomes in declarative and procedural knowledge contexts. A 2 x 2 factorial design was used, considering instructor type (human vs. humanoid APA) and knowledge type (declarative vs. procedural). The study involved 139 university students with no prior knowledge of the video content and was conducted in a human-computer interaction lab using an eye-tracking device. There were no significant differences in learning achievement, perceived lecture engagement, emotion, satisfaction, and social presence between the human and humanoid APA. However, learners showed greater visual interest in the human instructor, which influenced their interest in the learning content. Viewers of declarative knowledge videos showed more visual interest and achieved higher learning scores, while procedural videos increased lecture engagement, emotion, satisfaction, and social presence. The study suggests that humanoid APAs can effectively replace human instructors in educational videos and emphasizes the importance of considering knowledge types in video design to impact learning outcomes.
