Uses

Lecture recording has been used in the flipped classroom learning model as a means to provide materials outside of traditional lectures or seminars. Students are able to self-study by playing back and interacting with recorded lectures. Some educational institutions use lecture recording as a means to replace the traditional

with an online classroom. Lecture recording can also be used to create reference materials as a supplementary resource. Lecture recording is not always welcomed by university faculty. Faculty attitudes to this kind of technology enhanced learning may vary across disciplines. Student research has found that more students than staff expect lecture recording to be beneficial to learning. In the most part students watch lectures for pragmatic reasons rather than lecture quality. Students do not view recorded lectures as a replacement for attending live lectures, and often continue to attend face to face sessions. Students who use recorded lectures as a supplement sometimes score significantly higher in subsequent assessment. Some firms may also use lecture recordings as advertising, collaboration, or training materials. In addition, lecture capture technology may offer
