Lecture webcasts are readily available on the Internet. These include class lectures, research seminars and product demonstrations. Webcasts routinely combine presentation slides with either a synchronized audio stream (i.e., podcast) or an audio/video stream. Conventional web search engines retrieve this content if you include "webcast" or "lecture" among your search terms, or search a website that specifically organizes lecture content. But users, particularly students, want to find the place in a lecture when an instructor covers a specific topic. Answering these queries requires a search engine that can search within the webcast to identify important keywords. TalkMiner aggregates and indexes lecture videos available across the internet. The system processes RSS feeds from a variety of sites to collect lecture videos. The system automatically processes the video to generate metadata describing each talk including the video frames that contain slides, their time offsets, and the text recovered from those frames by optical character recognition. TalkMiner does not maintain a copy of the original videos. When a user plays a lecture, the video is played from the original website on which the lecture video is hosted. As a result, storage requirements for TalkMiner are modest.

"It is a common view that "if only someone could break this down and explain it clearly enough, more students would understand." Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it."

"The Periodic Table of Videos is a collaboration between the University of Nottingham's School of Chemistry and video journalist Brady Haran. We initially made videos about all 118 elements.

Video mirroring shows exactly what's on your device's screen on a second display, like a projector, television, or monitor. We're used to video mirroring with laptops--many teachers do this everyday. iPad 2 requires either the Apple VGA Adapter or Apple Digital AV Adapter. The VGA adapter connects to most projectors while the digital adapter connects to HDMI, which is common on newer televisions. Apple Digital AV Adapter also outputs sound while the VGA adapter outputs only video to the display."
