Discussion Questions
Objectives:
- Distinguish strengths and weaknesses among operating
systems.
- Compare and contrast the different network topologies.
- Identify computer components.
- Create an instructional/training project incorporating
multimedia features into presentation software.
Reading
Read Chapters 9 in Multimedia: Making It
Work
Chapter 9 is a good read for all of you. It
gives a good basic overview of the two major types of operating
systems and gives a good explanation of RAM, ROM, input and
output devices, and connectivity types (Modems, DSL, Cable).
This is a good chapter to read through just to get computer
and internet literate..
Training
Find tutorials
on PowerPoint or other presentation software on the Internet
and/or go through the tutorials found on the Tutorials
by Week page. Also, continue to work with the Basic Website
tutorial page to finish up your personal and team website
projects.
Projects:
Go to the Projects

Instructional Design
Review of Week 4
In Week 4 we talked about the development process
of designing a multimedia instructional site. Again, it tied in
the importance of project management because there are likely to
be many different pieces that must be developed separately and then
assembled to produce the final product.
In Week 5 you will read about integrating the user
interface pieces such as graphics, media, the actual look and feel
of the web pages with the ‘back-end’ programming. All through this
process teams have played a huge part in development and this week
we add the programmers who will add the functionality to the site.
Tag-Based Languages and Scripting Languages
Tag-based languages are known as mark-up languages
and some examples are HTML, XML, SGML, and WML. These languages
use tags that look like < > and have an opening and closing
tag. The tags tell the browser how to display the items between
the tags. HTML is much like the WordPerfect where you can select
the option to ‘Reveal Codes’ so that you can figure out why a word
that you thought you had bolded is not bold on the screen
Scripting Languages are high-level programming
or command languages that are interpreted or translated on the fly
to binary codes as opposed to being compiled ahead of time. Such
languages are either procedural or increasingly common as object
oriented. Some examples of scripting languages are JavaScript,
Visual Basic, and Perl (CGI scripts).
HTML is the essential language tool for creating
any Web page as contrasted with scripting languages, which are necessary
for rendering a simple and static page into a dynamic page with
interactivity.
Dreamweaver, FrontPage and GoLive do a nice job
of writing JavaScript and embedding media objects in WYSIWYG mode.
The also can debug basic problems with JavaScript and Java codes.
Interactive Multimedia
There is a subtle but significant different between
multimedia and interactive multimedia. Multimedia as we have been
defining it up to this point is different types or ways of presenting
information. Text, graphics, audio, video, etc. The user is able
to interact on a limited level in this description by starting,
stopping, and rewinding audio or video. But that’s been the extent
of the interaction.
In interactive multimedia, the user has a much
higher degree of control over what’s displayed on the screen. The
user can also interact with simulations and programs so that the
result is dependent on the input from the user. This type of interactivity
requires high-level programming or ‘back-end’ programming.
Simulations are computer-generated or presented
scenario or environments that imitate the reality, not only in terms
of results or appearance but also and more importantly in the interactions
and processes.
Some nice examples of math learning demonstrations
that use Java applets go to http://davidmlane.com/hyperstat/Instructional_Demos.html
and experiment with putting in different variables.
Tools that are commonly used to create interactive
multimedia objects are Macromedia Flash, Director, and Authorware.
If you are worried that bandwidth issues will affect
the interactive multimedia components that you would like to incorporate
into your instructional web site, you always have the option of
putting the media on a CD-ROM and sending it to your user. Usually
most media and multimedia will run considerably more predictably
from a CD-ROM. For the engineering courses I designed at UTA, we
put all of the media on CD-ROMs and packaged them with the textbook.
It becomes very clear from reading the text that
if you are going to do any type of interactive multimedia that requires
high level programming, you are going to need the expertise of a
programmer on your team. They should be involved in the project
from the start and will give you good information to work from to
be able to fulfill your clients’ requirements.
Remember the example I talked about in Week 1?
The lessons that were created in Flash but kept crashing the machines?
Well, the text talks about memory leaks, when a program does not
properly free up the memory after running, thus causing the machine
to crash. This is part of the problem they discovered with the
Flash modules they had created. It took them a long time to discover
that this was the problem and then to figure out how to fix the
‘bug’.
Speaking of bugs, I hope you enjoyed the story
of how the word ‘bug’ came about as a term that describes when a
program doesn’t work correctly. Here’s the link to Admiral Grace
Hopper’s log on that fateful day of Sept 9, 1947 and her ‘bug’.

Again in this week’s text, the role of the project
manager is central to the success of the project. The project manager’s
job gets more complex as the level of the interactivity increases.
Good project management skills are obviously a plus in these types
of situations. In my job, if it didn’t work right, or it didn’t
get done on time, I was held responsible, regardless of the fact
that I, personally, was not creating many of the pieces of the instruction.
It was through good teamwork, excellent communication, and lots
of chocolate chip cookies (my programmer’s favorite) that we were
able to meet our deliverable dates on time and many times earlier.
