Abstract
This study investigates how chatbot interaction modalities—text, voice, or avatar—affect university students’ critical thinking (CT), digital trust (DT), and user attitudes (UA) within an educational context. Building on a Design Science Research approach, an experimental chatbot artifact was developed, incorporating a hybrid dialogue system (Dialogflow CX and GPT-4) within a content-neutral, debate-oriented scenario to ensure rigorous experimental control and pedagogical relevance. A cross-sectional experiment was conducted with 90 university students, who were randomly assigned to one of the three chatbot modalities.
