Purpose: The purpose of this paper is to propose an indexing and teaching focus mining system for lecture videos recorded in an unconstrained environment. Design/methodology/approach: By applying the proposed algorithms in this paper, the slide structure can be reconstructed by extracting slide images from the video. Instead of applying…

Determined if college students learn better when using lecture/CAI than by using the conventional lecture method to present visually oriented material. Results indicated no significant difference between the test groups in amount of learning; also, it took longer to present examples to the control group than for the treatment group to absorb…
