Lecturer fools students by replacing himself with AI
An Australian university lecturer surprised students by replacing himself with an AI avatar during a teaching experiment, with many later saying they preferred the digital version.
An Australian university lecturer has discovered that students can be surprisingly accepting of artificial intelligence after replacing himself with an AI-generated avatar during a teaching experiment.
Dr Luke Rowe, a senior education researcher at Australian Catholic University (ACU), created the AI version as part of a lesson exploring the ethics and practical uses of artificial intelligence.
Many students did not immediately realise their lecturer had been replaced.
Despite clues including mismatched hand movements and speech, the AI avatar was convincing enough that students continued watching the lecture without identifying the change.
The biggest surprise came after students were told they had been watching an AI version of Rowe.
Some said they preferred the digital lecturer.
Rowe told The Age newspaper: "I was eating humble pie and I was sitting there going, ‘Why is that?’"
ACU said it had no intention of replacing academics with AI avatars but wanted students to understand how emerging technologies could be used responsibly in the workplace.
Rowe said AI avatars could have potential benefits in education, including allowing lecturers to deliver content in different languages and update teaching materials more efficiently.
He said: "Hopefully, my human judgment will exceed that of AI. But if we’re talking of efficiency, no way. AI can absolutely do this more efficiently than I can."
Other Australian universities are also exploring how generative AI could support teaching.
The University of Newcastle in Australia is testing short AI avatar videos designed to accompany online learning materials.
Professor Karen Blackmore, acting pro vice-chancellor for education innovation, said universities were looking at ways AI could improve teaching while maintaining academic expertise and human connections.
She said: "The university is taking a measured approach to the use of AI in teaching."
The experiments come as universities worldwide debate how artificial intelligence should be integrated into classrooms. Supporters argue AI tools can improve accessibility and reduce administrative workloads, while critics have raised concerns about academic integrity, privacy and the loss of personal interaction.
Elsewhere in Australia, La Trobe University has introduced an AI-powered robot designed to help teachers practise difficult conversations with parents.
Rowe’s experiment highlights how quickly AI-generated content is becoming realistic enough to challenge assumptions about human interaction.
While the technology is unlikely to replace educators entirely, universities are increasingly exploring how digital assistants and AI tools could become part of future learning environments.
