© 2008 Automatic Sync Technologies Changing The Model As The Models Change Move from accommodation to Universal Design Provide learners with control, options Transcripts instead of note-takers Recorded lectures for those immobile? Re-think transmissive pedagogical models --Park egos about attendance Andragogy vs. Pedagogy Just in time vs. just in case learning Appreciate preemptive multitasking, social networking modality of digital natives 13
© 2008 Automatic Sync Technologies 14 Appreciate Research Augmenting an auditory experience with captions more than doubles the retention and comprehension levels. Gary Robson, The Closed Captioning Handbook People retain about 20% of what they hear, 30% of what they see, and 50% of what they hear and see. Dales Learning Cone of Experience (www.willatworklearning.com/2006/10/people_remember.html)www.willatworklearning.com/2006/10/people_remember.html Confucius :"Tell me and I'll forget. Show me and I'll remember. Involve me and I'll understand
© 2008 Automatic Sync Technologies 15 Adult students that used captioned video presentations progressed significantly better than those using traditional literacy techniques. Benjamin Michael Rogner, Adult Literacy: Captioned Videotapes and Word Recognition Dual Coding Theory postulates that both visual and verbal information are processed differently and along distinct channels with the human mind creating separate representations for information processed in each channel. Allan Paivio, University of Western Ontario More Research
© 2008 Automatic Sync Technologies Multi-Modal Learning 16 Use 2 or more senses to avoid sensory overload (Granström, House, & Karlsson 2002, Clark & Mayer 2003) Read it: transcripts of the instructors presentation are available Hear it: audio of the instructor maps to the video of the presentation See it: presentation materials, screenshots, and diagrams appear on-screen synchronized with the instructors words Do it!
© 2008 Automatic Sync Technologies Learning Outcomes: SFSU Study Instructional video materials delivered randomly to students-50% with captions 50% without Two trends emerged: o No captions: students were quite passive and silent during class discussions - with the "usual speakers" dominating the conversation and generalizations were pervasive. o With captions: students were more engaged and responsive to the questions asked about the film. In a similar vein, students made interesting analogies to their everyday lives and reference to specific information and events from the video was much more abundant. GPAs were 1 full point higher with population exposed to captions Source: And Captions For All?

© 2008 Automatic Sync Technologies 18 Better Absorption of Material o It helped me to catch words that I didn't understand, and also helped with spelling. o It allows me to pause the lecture and take notes from the captions when my note-taking lags behind the spoken lecture. o I caught several things the second time around reading captions that I did not listening the first time around. Allows Better Interactivity with Course Material o I much prefer the captioned lectures and being able to look at the links while you are talking. So far this has been the BEST online class I've taken at SJSU, others should learn from your example. Students Speak-SJSU
© 2008 Automatic Sync Technologies 19 Diversifies Delivery of Video Media o I was able to read at my desk without having the audio turned on so that others in my office wouldn't be bothered. o Captions also allow you to view videos when you are in a situation where you are not able to use sound. Students Speak
© 2008 Automatic Sync Technologies Captions and transcript text can be used as meta-data for SEO (search engine optimization) Can work with variety of tools: Google video, AST search, Reelsurfer CNET captioned video drove 30% increase in Google hits Captions Improve: Searchability, Discoverability, Navigability
© 2008 Automatic Sync Technologies 21 The Stick: Accessibility & Legal Compliance Federal, State and Local, System-wide, campus initiatives Federal Accessibility legislation: ADA, Section 504, Section 508 NY, TX, MO, NC, VA, IL, OK, CA have accessibility laws for education. Missouri passed captioning law for publishers with treble damage penalties State law summary at:
© 2008 Automatic Sync Technologies 22 Section 508 requires Federal electronic and information technology to be accessible to people with disabilities, including employees and members of the public. § Web-based intranet and internet information and applications. This section applies to all websites and is not unique to training materials or online courses. The standard requires that web content be constructed and tagged in a manner that enables the effective use of screen readers and other technologies that allow people with disabilities to access internet content. The commercial marketplace includes numerous design tools, checking methods, and training courses to assist website owners to comply with Section 508. § Video and multimedia products. This section contains two provisions that apply explicitly to training and informational video and multimedia productions. These provisions require a) captioning of any speech or other audio information that is necessary for the comprehension of the material and b) audio descriptions of any visual information that is necessary for the comprehension of the material.

© 2008 Automatic Sync Technologies Creative Uses of Transcripts & Captions 39 Students retain more if they are able to 'read ahead' and have more of the transcript visible
© 2008 Automatic Sync Technologies 40 VTEs Providing a Full Transcript Offers: The ability to perform deep searches The ability to print, download, and annotate course materials to improve retention. VTE allows the student to unlink the transcript and treat it as a standalone asset. Additional time to review materials. In some cases, students may not natively speak the instructors language. Having a verbatim transcript allows them to pause the audio lecture and look up words they need to clarify without missing any of the material. Compliance with American with Disabilities Act (ADA) standards.

© 2008 Automatic Sync Technologies 44 Evaluating Captioning Solutions Does it meet the need? Accuracy, quality, speed… Cost? Reliability? Scalability? Ease of use: minimal impact on workflow?
© 2008 Automatic Sync Technologies 45 Captioning Approaches Considered: Realtime vs.Offline Student labor Speech Recognition solutions Outsource captioning vendors
© 2008 Automatic Sync Technologies 46 Initial Findings Stakeholders did not all fully appreciate the scope of the problem, what is required to create a compliant result, or the cost involved. Individual campuses did not have adequate resources to leverage bulk discounts. Search for a silver bullet solution sometimes kept people from finding reliable, effective solutions.
© 2008 Automatic Sync Technologies 47 Initial Findings Large-scale student-based transcription was difficult to build and scale reliably; more expensive than it first seems. Speech Rec solutions do not produce a compliant, usable result due to high error rates. The labor cost to repair the results makes them uncompetitive. Most campuses were already working with or experimenting with Automatic Sync Technologies.
