Authors - Ntima Mabanza Abstract - Research that examines the use of Pedagogical interface agents (PIAs) in digital learning environments has demonstrated that PIAs can increase learner engagement, motivation, knowledge retention, and improve the learning outcomes. Despite that, there is limited empirical understanding of which PIA’s particular features are very noticeable and preferred by learners. A mixed-methods approach was used in this study, combining initial training, task completion, and feature rating questionnaires with 62 adult participants. This approach was used to examine adult learner preferences for PIAs’ noticeable features, such as appearance, voice, and movement. The study findings indicate that adult learners prioritize PIAs’ movement, followed by their appearance, and lastly their voice. The findings of this study provide very useful design guidelines for developing effective learner-centered PIA systems that maximize engagement and satisfaction.
