Faculty Jim Rothenberger
-has taught alcohol education for 30 years and
served in academic administration -saw pattern of
high risk when students first get to
collegeacademic, student affairs, health,
legal, and safety all can suffer -wanted a course
addressed directly to students in that high-risk
windowfirst two weeks of college

First there was a CD
CD-created around multimedia assets-built in
Authorware-delivered on CD-not for credit -one
copy given to every incoming first-year student
on campus

and a Web site
Web site-text-oriented-written in
HTML-delivered in WebCT-1 credit class (PubH

Mode of address
Critical to avoid-stern lectures-The After
School Special-scarifying tacticsimportant
to-engage students desire to learn-build on
concrete knowledge of social context-preserve
informality of conversational speech-tell
stories in students own voices

Case study video

Documentary video
Find students and conduct structured interviews
of open-ended questions. c. 20 hours raw
footagec. 60 minutes final running time201
shot ratio Common practice, works wellGo into
field with list of question topics and be
prepared to invent meaningful follow-up
questions.

Dramatic video
-recreate orientation skits in front of
camera?-write scripts?-hire actors?-Recruit
interested undergraduates, form an ensemble, and
let them invent dialogue.

Dramatic video
Recruit interested undergraduates, form an
ensemble, and let them invent dialogue. c. 10
hours raw footagec. 20 minutes final running
time301 shot ratio Uncommon practice, can work
wellGo into field with where scene should go,
be able to let go and let actors create the
scene, and be prepared to do lots of takes.

Tech video
client-side/player-Authorware QuickTime (Mac
and PC)-Web latest Flash playercompression-Q

Sorenson SqueezeeditingFinal Cut Pro, v. 1.25
through 4.x

Tech bandwidth
Two models for bandwidth-detection1.
QuickTime-requires user to know what bandwidth
is-requires user to select a setting-doesnt
change when bandwidth conditions change2.
Windows Media Player-automatically detects
current bandwidth
13
Tech video bandwidth
Two sizes of video1. big150 kbps20 kbps audio
(.MP3) 130 kbps video (Sor.)15 fps240 x 180 pxs
2. small28 kbps20 kbps audio (.MP3) 8 kbps
video (Sor.)1 fps (5-10 sec/f)160 x 120 pxs

Voice over
Audition and recruit interested undergraduates
from Radio K (college radio station) to record
voice over (VO) for project. c. 40 hours to
recordc. 60 minutes final running time Common
practice, works wellFinal copy of script, then
bring talent in for VO.

Tech audio bandwidth
Two forms of audio1. VO28 kbps (.MP3) mono

Music
Audition large number of recordings (radio,
Internet, clubs, personal collections), solicit
permissions. c. 30 minutes final running
timeAnd now, Soundtrack.

Usability testing
questions1. In a multimedia environment, do
students prefer to be shown one thing at a time
or to choose which asset to attend to?2. Does
our new UI work? Standard practice, works very
wellContract campus ISO to conduct human
factors analysis and testing on new UI n7,
another round of testing in the fall
18
Finally rich media on the Web
-HTML-iFrames-all assets in Flash-two sizes of
video, auto-detect bandwidth, auto serve
appropriate size-tested UI-scaleable model for
redeployment-db-backed, allows
customization http//www.epi.umn.edu/cd_generic/h
