As the Internet bandwidth grows to support more and more video there is a growing trend to use this in education. There's little doubt that video can be very useful for some contexts and for demonstrating particular concepts.
But, is video becoming a lazy way for people to provide information?
Many videos are just of people talking; and the quality of the information provided depends on the quality of the talk, and the usefulness of its content. There may be a danger of thinking that because video is a new thing - on the Internet - that it is always useful.
Students, and lecturers, could reflect on the following question:
Have you ever been to a lecture that was useless? And, will an online video of that lecture make it any better?
