Is Streaming Media the Right Choice?

There are a variety of media formats that can fa-

cilitate the successful delivery of online instruc-

tion; the one you choose should reflect the goals 

and abilities of your instructors and learners. 

This  guide  is  based  on  the  redesigned  online 

Engineering  Communications  Tutorial  at  the 

University  of  Texas,  developed  by  the  McKin-

ney Engineering Library in partnership with the 

Digital Information Literacy Office and Digital Li-

brary Services Division. The tutorial underwent 

analysis  and  revision  with  the  goal  of  creating 

effective library instruction with guidance in mul-

tiple  languages  and  diverse  media.  Streaming 

media  was  the  format  selected  for  the  project 

because it would allow the development team to 

use separate audio files for each language while 

drawing from a common bank of visual imagery. 

The  images  and  audio  files  could  be  synchro-

nized using the Synchronized Media Integration 

Language, or SMIL.

Other  formats—such  as  Flash  and  simple 

HTML—were rejected for a variety of reasons. 

Although Flash offers many interactive features 

that  lend  themselves  to  the  development  of 

rich  learning  experiences,  Flash  animation  is 

far more time-consuming to produce and more 

complex to modify than a SMIL-based tutorial. 

In addition, Flash production requires a highly-

specialized  set  of  technical  skills  and  costly 

software. The use of simple HTML was rejected 

because an audio component was deemed cru-

cial to the multi-lingual sections of the tutorial.

When  you  are  deciding  on  a  format  for  your 

tutorial, remember to consider your audience’s 

learning environment. If you expect the majority 

of learners to use a dial-up connection or older, 

lower-speed computers, you may wish to avoid 

bandwidth-intensive solutions that rely upon the 

latest  browsers  and  plug-ins.  FlashMX  is  an 

example of current technology that is not ubiq-

uitously  available.  Even  SMIL,  the  technology 

recommended in this guide, has cross-platform 

limitations. 

Looking Ahead

Although  this  guide  focuses  on  the  produc-

tion  of  audio/visual  elements,  the  Engineering 

Communications  Tutorial  development  team 

acknowledges  the  importance  of  active  learn-

ing  in  online  library  instruction.  Nancy  Dewald  

notes  in  the 

Journal  of  Acadmic  Librarianship

 

that “active learning is accomplished with indi-

vidual  or  collaborative  exercises,  questioning 

by  the  librarian...  or  other  forms  of  practice  to 

reinforce  instruction.”

  Similarly,  Brandon  Hall 

states in the 

Web-based Training Cookbook

 that 

“Interactivity    makes  the  difference  between  a 

program  that  simply  presents  information,  and 

one  that  actually  trains  the  user.

2

  By  integrat-

ing streaming media instruction with interactive 

segments like quizzes, assignments, or follow-

along exercises, the effectiveness of your tuto-

rial may be improved. Keep in mind that even on 

the Web, 

doing

 is a better teacher than simply 

watching and listening.
