These are the recent Internet technology advances that have made
publishing on/with the internet more attractive to publishers:
- Mosaic/World Wide
Web
-
These new protocol and display technologies have a short learning
curve for students and instructors (and publishers). These easy and
nearly ubiquitous technologies make publishing electronically more
attractive and accessible.
- Forms
-
Easily implemented way to get feedback, have interaction (testing,
comments, etc.) If you've never seen a form, try one now. These
are HTML pages that send their contents off to computer scripts run by
the Web server (not on your browsing machine).
- Scripts
-
Using the output of forms or just sending output to a downloaded page,
scripts on a Web server can spit back results based on the contents of
a form, thank you for your submission, or give you access to another
page. They can also do mathematically/pedagogically useful functions:
searching, calculation, testing are all possibilities.
- Java
-
On-demand custom applications limited only by the imagination. The Geometry Center is writing some
java applications to allow rotation of figures, and mathematical
typesetting and calculation through a web page.
- <MATH> HTML markup tags
-
No, really, this is supposed to happen soon.
The Arena
Browser already reads some of the Math Markup (UNIX only) but the
preliminary
specification already exists for these tags. We're just waiting
for the commercial browser companies to catch on to this, particularly
Netscape Communications. You should send them mail requesting this feature.
- Hardware Advances
-
Faster processing, more net connectivity, infrared access, color
monitors, and CD-Rom make technology viable for teaching. New
hard/software options may also lead to reduced cost per student of
technology instruction through the use of the server/client setup
implied by Web technology.

- Tie education to the rising productivity enabled by technology.
- Pull down the entry cost per seat by an order of magnitude by
using local (dumb) renderers, and keeping the computing power in a
single station, i.e. sharing compute cycles.

- Many types of tools on demand
-
Computer manipulatives, computer algebra systems, movies, sounds, etc.
can be incorporated as viewers or
helper applications in Mosaic. Mosaic will let you hyperlink to
ANYTHING, and launch the appropriate application to run the linked
file. Netscape even incorporates "plug-ins" to let you play files inside the same window,
like Quicktime and Director movies.
- Instructor's Perspective/Customization
-
Seamless, and simple, incorporation of an instructor's own perspective
and materials into a published product if desired (on-the-fly custom
publishing). The simplicity of
HTML coding also means that authors can easily take an active role
in creating the final electronic product, which is often part of the
expense and overwhelming production burden that makes publishers shy
away from this sort of publishing.
- Real world data
-
Access through the 'net to "real world" datasets and "power tools"
will lend an active learning aspect to any course, and show the
utility of the material. It's like having an infinite case study
laboratory.
- Collaboration
-
Student-student/student-instructor collaboration through shared
physical or virtual workspaces.
- Self-remediation
-
The hypertext environment lets the student see the connectivity of the
course material, and helps them to help themselves.

Inc.
- Hypertext lets a student self-remediate by following related
links, reminding them of forgotten or missing material in their
backgrounds.
- Hypertext lets students explore subjects which are beyond the
scope of the typical course.
- The trick to writing a hypertext is to evert the material,
starting with where you'd like to go, and letting the reader decide
how much background they need or want.

- Subscription
-
Either entirely online or disk/online combination with a yearly
registration fee for a password or other access.
- Site Liscence
-
School running sets of files on the school's server decreases wait
time, but requires system administration support.
- Local/net services separate
-
CD-Rom delivery of "static" files, with online updates, chat groups,
new materials, script/java-based tools, possibly on a
subscription/upgrade basis.
- Free OnLine companions
-
Updates and internet-related support of printware available
continuously for free.

For an example, see the everted lab/supplement project in Calculus: Calculus
Modules OnLine, which includes computer algebra viewer files,
images, movies, and some examples of various hypertext devices to
navigate in an environment. A fuller description of this project from
a hypertext development standpoint is available in the DAGS '95
proceedings.
Another good example of an everted text can be found at
Northwestern University.
