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.

"What follows is an explanation of the Flipped Classroom Model, a model where the video lectures and vodcasts fall within a larger framework of learning activities. (Note: I am titling it the Flipped Classroom Model to get folks' attention given the Flipped Classroom popularity right now.  It really is a cycle of learning model.)  It provides a sequence of learning activities based on the learning theories and instructional models of Experiential Learning Cycles - http://reviewing.co.uk/research/learning.cycles.htm and Bernice McCarthy's 4MAT Cycle of Instruction- http://www.aboutlearning.com/what-is-4mat/what-is-4mat.

""Technology is central to how we learn and how we communicate," Florence said. "This is an initiative to allow faculty to experiment with how tablet computers can help improve and expand their teaching.""
