Lectures play a pivotal role in education, serving as the primary medium through which educators present specific topics from a curriculum. Although lecturing is usually a linear and one-sided process, where teachers serve as knowledge givers and students as receivers , some pedagogical models suggest that more productive approaches can involve more active roles form the student's side, mediated by different levels of intervention . Under these views, lecturing is a more dynamic and bi-directional process, where the advent of LLMs offers unprecedented possibilities in the lecture planning and delivery stages as shown in Figure . These systems potentially offer a host of benefits that extend beyond mere content enhancement. From providing instant feedback and generating thought-provoking questions, to adapting discussions, LLMs will assist educators through several stages of lecture preparation.
