Transcript

  • 1. Lecture Capture Faculty Technology Lunch 2008/04/22 Chris Warren OIT Williams College
  • 2. What is lecture capture?
    • Recording audio, video, and projections from lecture-style presentations of information
      • Audio – the lecturer uses a clip-on microphone
      • Video – there is a video camera in the room
      • Projections – the signal is split and saved
    • The three kinds of recordings are synchronized, packaged, and made available on-line
  • 3. Benefits lecture capture
    • http://www.wpi.edu/Academics/ATC/Collaboratory/News/lecturecapturing.html
      • “ Students feel that the recorded lectures have a positive impact on their performance and 94% of students would like recorded lectures available in more courses.”
      • “ Students and faculty both claim that the recorded lectures do not impact attendance”
    • http://www.echo360.tv/customers/umass.asp
      • “ 72% of students said that the Echo 360 lectures had contributed to their understanding of the subject matter”
      • “ Students in Echo 360 -enhanced Calculus courses had a success rate (a grade of C or better) 11 percent higher than their peers, and received 10 percent fewer Ds, Fs, or withdrawals.”
      • “ Echo 360 has a transformational effect on my students who've historically been in the bottom half of the Green Chemistry grading curve of 40% or less”
  • 4. Benefits lecture capture
    • http://campustechnology.com/articles/52017/
      • “ Results from an initial study by a professor at Coppin State University in Baltimore indicate that class capture technology that allows students to view lectures online after the fact can improve course retention rates and grades” (caveat: “the data are preliminary, since they focused on a single course”)
    • http://www.dartmouth.edu/~create/
      • “ While course capture clearly benefits students who miss class, Witters has found that all students gain from access to the recordings, particularly when it comes time for review.”
    • http://edc.carleton.ca/blog/index.php/2008/02/12/enhanced-lecture-podcasting-benefits/
  • 5. How students use it
    • Post-class review
      • To review a confusing point
      • To take notes
      • To clarify comprehension of the language
    • While doing home work
      • To answer specific questions
    • Test / quiz preparation
    • After missing a class
  • 6. What is lecture capture?
    • http://acm.williams.edu/acmcontent/e28cdbca-a22f-4e6d-989f-8c86219ae8df/Mini-Workshop_20080109-1400_2008-01-09_02-00-PM_files/flash_index.htm
  • 7. How lecture capture works
    • Instructor contacts OIT and requests it
    • Instructor puts on the clip-on, wireless microphone at the start of class
    • Lecture audio, video, and projection are automatically recorded
    • Recordings are automatically synchronized, packaged, and posted to Blackboard
  • 8. Lecture capture doesn’t work as well* for
    • (* in our current set up)
    • Discussions or highly interactive presentations
    • Anything with lots of mobility
    • Anything without a distinct, fixed center
    • Presentations that don’t use the projector
    • Anything you’d want around for more than a semester
  • 9. Lecture capture is best for
    • Lecture-style classes
    • Classes that require a lot of review
    • Classes that require memorization
    • Classes where basic comprehension is an issue
    • Presentations that take advantage of the projection system
    • Any time the students would want to see and hear the lecture multiple times
  • 10. Lecture capture at Williams right now
    • 3 classrooms currently set up with fixed systems
      • Jesup 205
      • Jesup 206
      • CDE classroom
    • We would like to convert one or two of those to be mobile systems
    • Used by OIT to record workshops
  • 11. Future lecture capture at Williams
    • How would this technology best help our students?
    • What are the instructor’s requirements?
    • What classes would be best suited?
    • What would be the best places for fixed systems?
    • How can we make this work?
