The increasing popularity of online courses has highlighted the need for collaborative learning tools for student groups. In addition, the introduction of lecture videos into the online curriculum has drawn attention to the disparity in the network resources available to students. We present an e-Learning architecture and adaptation model called AITV (Adaptive Interactive Internet Team Video), ...

Human communication takes many forms, including speech, text and instructional videos. It typically has an underlying structure, with a starting point, ending, and certain objective steps between them. In this paper, we consider instructional videos where there are tens of millions of them on the Internet. We propose a method for parsing a video into such semantic steps in an unsupervised way. ...

Positron emission tomography of cerebral glucose metabolism in adult human subjects was used to investigate amygdaloid complex (AC) activity associated with the storage of long-term memory for emotionally arousing events. Subjects viewed two videos (one in each of two separate positron emission tomography sessions, separated by 3-7 days) consisting either of 12 emotionally arousing film clips (...

BACKGROUND Direct ophthalmoscopy is well-suited for video-based instruction, particularly if the videos enable the student to see what the examiner sees when performing direct ophthalmoscopy. We evaluated the pedagogical effectiveness of instructional YouTube videos on direct ophthalmoscopy by evaluating their content and approach to visualization. METHODS In order to synthesize main themes a...

The use of video for instructional purposes has exploded online, but little is known about how people interact with video differently than other instructional materials and how much they learn from those lessons. Kintsch’s (1994) model of text comprehension provides a productive model for studying how students build a semantic representation of materials that unfold over time but have an overar...

We propose a temporal segmentation and procedure learning model for long untrimmed and unconstrained videos, e.g., videos from YouTube. The proposed model segments a video into segments that constitute a procedure and learns the underlying temporal dependency among the procedure segments. The output procedure segments can be applied for other tasks, such as video description generation or activ...

We examine algorithms for creating indexes into ordered series of instructional lecture video transcripts. The goal is for students and industry practitioners to use the indexes towards review or reference. Lecture videos differ from oftenexamined document collections such as newspaper articles in that the transcript ordering generally reflects pedagogical intent. One challenge is therefore to ...
