What impact did AI-powered chatbots have on university students in Australia?

AI-powered chatbots have made significant strides in enhancing the educational experience of university students in Australia. The correct choice reflects the measurable positive impact of these technologies on academic performance, specifically through a nearly 10% improvement in exam grades. This improvement can be attributed to the various ways chatbots support student learning, such as providing instant feedback, answering questions outside of classroom hours, and assisting with study materials, ultimately leading to better understanding and retention of information.

As students engage more actively with their learning resources through chatbot interactions, they can clarify doubts promptly, which contributes to more effective preparation for exams. The other options suggest different figures or outcomes which, while they represent desirable educational benefits, are not in line with the documented improvements attributed specifically to AI chatbots in this context.
