From lecturer to content creator: refocusing the lecture for impactful learning in medical education

Medical education is challenged by the exponential growth of biomedical knowledge and associated information overload, which places significant cognitive strain on students. This pressure, alongside the ubiquity of lecture capture, has fundamentally altered student engagement: students are no longer passive recipients in live settings but active curators of asynchronous content, relying on lecture recordings and transcripts as a central and flexible study tool. This is evidenced by a noticeable decline in in-person lecture attendance. Crucially, students are increasingly integrating generative AI tools to transform lecture recordings and transcripts into personalized, on-demand study aids, such as digital tutors, concept summaries, and practice quizzes. This paper argues that faculty must strategically respond to this shift by redefining their role from traditional lecturers to content creators focused on designing durable, asynchronous educational assets. The core strategy involves prioritizing the recorded medium to employ intentional instructional design. By applying principles such as Richard Mayer's Multimedia Learning (e.g., segmenting, coherence), educators can effectively reduce extraneous cognitive load and measurably improve student satisfaction and learning performance. Furthermore, this transition is important for strategically harnessing the benefits of artificial intelligence. Providing faculty-vetted content to AI systems helps promote the accuracy and curriculum alignment of AI-driven study tools, mitigating the risk of hallucinations. Ultimately, aligning content creation with modern student study habits can better support self-directed learning. Embracing the content-creator mindset is a necessary adaptation for establishing a more effective, student-centered medical education environment.
