Critical Thinking in Distance Education: The Challenges in a Decade (2016–2025) and the Role of Artificial Intelligence

This qualitative study investigates how critical thinking is cultivated in postgraduate distance learning, focusing on two time points, 2016 and 2025, in the context of the Greek higher education system. It draws on semi-structured interviews with 30 participants (15 tutors and 15 students or graduates) from two online postgraduate programmes: Education Sciences and Education and Technologies in Distance Teaching and Learning Systems. Thematic analysis was used to explore participants’ perceptions of critical thinking development. The two-phase comparison captures how understandings and practices have evolved, particularly in light of the emergence of generative AI between 2016 and 2025. In Phase B, this research specifically examines AI’s potential role in supporting critical thinking and the pedagogical adaptations required by tutors. Nine key themes were identified. One of the most pressing concerns raised was that educators are perceived as largely ineffective in fostering critical thinking through online teaching. This study contributes empirical insight and practical recommendations to improve critical thinking cultivation in digital learning environments, especially in the age of AI.
