The Next Step
in Engaging Students
3
Six “simple” steps

13
More teacher reactions
  • Students were super attentive & focused for the starting and stopping.
  • Liked multiple ways of presenting - helpful for different learners.
  • Liked controlling where you go and having activities to break up the video.
  • Put more words on the screen to help the more visual learners.
14
Lessons learned: Content
  • Teacher materials (guides, lesson plans, background information).
  • Guided activities for students.
  • Multimedia resources for students (maps, photos, source documents, virtual tours, etc)
  • Link to Web for even more resources.
  • Other languages/closed-captioning.
15
Lessons learned: Production
  • Think DVD-ROM (for this platform)
  • Compatibility - first and always
  • Focus on one platform at first
  • To m2p or not m2p? MPEG issues
  • Start with what you know - html, tools, etc.
  • Count on Murphy’s law corollary:
  •  “Nothing will work right the first time”
16
Lessons learned: Datacasting
  • Antenna placement is key/test sites first
  • 700 Kb/s avg. speed of opportunistic data
  • (Delivers a cd-rom in 2 1/2 hours)
  • More bandwidth (i.e. 15.2 Mb/s around sdtv signal) & cd-rom sent in about 10 minutes
  • Process adds 50% more to data sent
  • Resending/back-channel helps if errors
  • Remember: Mb is speed; MB is size
17
More uses of datacasting
  • Near-video on demand (episodes & clips)
  • Deliver teacher guides, documents
  • Interactive telecourses (mpeg-based)
  • Sell & deliver CD-roms, DVDs to schools
  • Send data for schools, corporate customers
  • Send Web site--with mpeg video clips
  • Send school content to other schools
18
Applying lessons to new content
  • Think iTV, enhanced from day 1
  • Support student exploration, searching
  • Assessment: give suggestions, “games”
  • Accessibility: NCAM - www.dtvaccess.org
  • Help screens, prompts for options
  • User-friendly, integrated teacher guides
  • More integration of narrative & interaction
19
More content-related issues

  • Rights, rights, rights
    • Producers, distributors
    • Security/encryption software or formats

  • Teacher training - moving from an ITV to an iTV world
20
Possible next steps
  • Complete “Hand in Hand” ITV/iTV series
  • Create more repurposed content?
  • Datacast via own stations; decide on bandwidth allocation
  • Datacast to school server; move iTV over school LAN to computer labs
  • Test datacasts of on-demand video
  • Enhance professional development series
21
Plenty of questions remain
  • Convergence of iTV, on-demand video & digital asset management?
  • Hard drive/disks vs. datacasts?
  • Intentional focus on learning styles?
  • Helping schools with testing issues?
  • Sustainable business models?
  • Sharing resources between stations?
  • Ongoing forums for lessons learned?
22
