SEEDS: World Wide Web Applications in Education
by Griff Richards, BCIT Technology Centre
    
Introduction
The ubiquity of the world wide web can not be ignored. The Web has
quickly become part of our culture. The challenge of the web is not
just to do something (we're over that stage) but to do something that
is educationally valid and useful.
Goal
This site will introduce you to the basics of the Web and point you to
useful resources for using and developing educational
applications.
Basic Concepts
The World Wide Web (WWW or the "Web") is a global information resource made possible by:
- the linking of thousands of computers to form the Internet, and
- the use of HyperText Transfer Protocol (HTTP) as a common protocol for transferring pictures, text and other media.
Information is written up using HyperText Mark-up Language (HTML)
and placed in a text file with .html or .htm (PCs)
for an extension. This file is stored on a server, the
computer providing the information. The file is given a Uniform
Resource Locator (URL) , a unique address consisting of the
server's address and the directory and name of the file. For example,
the URL for this page is
http//www.arcs.bcit.bc.ca/seeds/www/index.html.
To use the Web, your computer must be connected to the Internet and it
must have client software to decode the HTML. (Educators can
obtain client software such as NETSCAPE for free - ask your campus
computing group!). When the URL is entered, the client sends a request
to the server and the server transfers the file to the client.
Sometimes transactions are instantaneous. But, if the server is busy
handling too many clients, or there is too much traffic on the
Internet, then the transaction can be slow or fail completely. The
faster the connection and more direct the link, the better the
service. Larger files (like pictures) usually take more time to
transfer than small files.
Web documents often incorporate hyperlinks that point to
other related information. Clicking on a link can move you to a different part of the file, or to another URL. Links can also be hidden under
graphics such as the apple below.
Design Considerations
Design is a question of taste, and debates rage on about the "right" way to build web pages. A few rules of thumb:
- Keep it simple. Start small with a clear idea. Work from an outline. An ounce of design goes a long way in promoting usability.
- Don't use too many "features" that will clutter the screen, distract, make things hard to read, or demand too much bandwidth.
- Keep your images as small as feasible...use thumbnail sketches to allow the user to decide if the full image should be downloaded.
- Begin each file with a table of contents. End each item with a pointer back to the top.
- Put long articles in files for downloading.
- Use the computer for interaction and comunication.
- Listen to the feedback from your victims. Think about how the web component will mesh with the rest of the course.
- Don't invest in adjunct or optional materials. Invest your time in something that will free you to be more effective.
As you gain experience and learn new tools (some yet to be invented) it will become easier
to break out of what some call "the tyranny of textuality" and introduce more multimedia components including movies and sound
into the message design. Since the web is rapidly evolving it may be tempting to show off webmastery of the latest techniques, however it might be more effective to keep things simple and concentrate on the needs of your audience.

site. For an overview on design heuristics, visit the
SUN Styleguide, and be sure

Teaching and Learning
"Four major classes of networking use have the potential to make a
major impact on science education over the next decade: resources,
tools for inquiry, collaborative inquiry, and Net courses." Robert
Tinker, The
Whole World in Their Hands
Just as the Web has become a way for businesses to "have a presence"
in the global economy, educators can also show their wares, advertise
their services and to some extent, transact the business of
education.
Range of Applications
- to make available course outlines
- to provide copies of course materials
- to provide research links to further readings
- to post frequently asked questions (FAQ's) somewhere so they don't have to be asked again.
- to develop a presentation of the knowledge learned
- to provide interactive instructional materials
- to provide on-line evaluation instruments
- to advertise the institution and availability of courses
- to share information about research interests
- This space reserved for the next great application
One of the great challenges of the web is that much of the future is
undefined. Growth may level off when the number of users matches the
number of desk-top computers, or when delays in servers or bandwidth
slow communications to the point where users are no longer willing to
wait. In the meantime, it is "hot", and if your students are
bonafide members of the cyberspace, then Internet applications may be
very useful in shrinking barriers of distance and time.
Roles of teachers and learners
"In what ways can this new technology enhance my teaching? Since
I believe this technology can do wonderful -- different -- things for
the classroom, I look forward to breaking out of the linear,
paper-like presentations." Wendy Burton, UCFV.
Teachers are not limited to the role of information providers. At the
Connections '96 conference Charlotte Green suggested the following
intiatives to enrich the student learner experience:
- shifting critical analysis from teacher to student
- freeing up face to face student-faculty time for best use
- building problem solving activities as well as content mastery
- fostering student driven class discussion
- continuously updating the curriculum to industry standards
- involving the external community in the assessment process.
Creative use of the web can invert the process so that learners work
collaboratively to create a web site themselves. The review and hence
evaluation of the site can be open to a broader audience than the
traditional class model allows. The key to successful use of the web
lies in its ability to make resources available and to promote
communication between teachers and learners alike. See also Computer Mediated Communication.
The Future of
Networking Technologies for Learning provides a thorough
discussion of web-related educational issues from curriculum to
connectivity and change through community involvement. To keep abreast
of new ideas, their web applications and their impact on teaching and
learning, keep an eye on pointer sites such as Yahoo
- Education, reference sites (e.g.ERIC), or on-line magazines (e.g.Online Educator).
Examples
The following examples have been drawn from British Columbian sources to show what's possible and to identify potential resource people in the province.

Hall.
Lessons Learned
The early users of the Web for education have found that it has both
strengths and weaknesses. For example:
- Anonymity ("On the internet nobody knows you're a dog!") for some, personal characteristics which might lead to subdued social involvement in a traditional class setting are masked by the guise of e-mail.
- The distance you are closing may be closer to home than you think - most web applications are currently used within institutions rather than for distance education.
- Access to the internet is not equal. Geographic location plays a large part in determining the quality and cost of service you will get. Learners in farflung regions may have very costly telephone bills to become linked to an internet service provider. Folks with older computers and slower modems will be poorly served by the current rage to produce complex pages with big art. (But not with little artsy seed packets!).
- Web sites are only as good as their last update. Information which becomes quickly stale will require constant updating.
- Information on the Web is only as reliable as its source. The unwary can easily be misled if they use information without validating it premises. Electronic literacy may become the next wave of hype and all the schools will implement electronic literacy programs. (Maybe it will be taught by T.V.??)
Here's what some users (both teachers and learners have to say):
a. teachers using the web
- Its a great way to organize your course
- It's easy to convert course outlines into HTML files, but it's a lot of work to make the content really interactive. This needs a lot of planning and testing. To do it right needs an assistant to keep all the files in order.
- I liked being able to put up information quickly and modify it as feedback came in from the students. The FAQs saved a lot of office hours.
b. learners tell their tales
- The information is nice but us it's a slow grind to run through a modem.
- I thought the web was supposed to enhance interactions, not replace them!
- Now I know what it feels to be a techno-peasant.
- I liked being able to do my coursework when and where I had the time.
So you're still not deterred and want to know where to start:
Well, here's a list of web sites that point to how to get started.
The first step is to understand a little bit about hyper-text mark-up
language or HTML. This forms the basis for web documents. After all,
the beauty of the web is that if everybody follows the same mark-up
conventions, then it can be read by web browser software (clients)
installed on your computer. This means you don't need to publish a
separate edition of you documents for Macs or for PCs.
- Ed-Web is designed for educators in K-12 and has one of the easiest HTML courses. Of course, there's lots of other information there too.
- Maricopa Center for Learning, Arizona has a major "pointing site" for educators as well
- University of Indiana shows lots of neat examples.
- Many good suggestions are found in pointers on the web site of Algonquin College in Ontario
- And if you are seriously wanting to "put your course on-line" just fill in the blanks on these HTML templates available from the University of South Carolina.
- A nicely designed site with lot's of tips for getting going is
Simon Fraser University - Faculty of Education
- Thinking of testing learning objectives? Check into this site at Oxford.
- And finally here's a pointer site to gerneral references for advancing the sophistication of your web site, the Charity Village Webmaster's Club.
Hard Copy References
Caution: Internet-related developments are moving so quickly
that technical references over two years old may be
obsolete. Publications dealing with educational principles and
applications have a greater longevity.
Hoffman, P. E. (1995). Netscape and the World Wide Web for Dummies. Foster City, Ca.: IDG Books Worldwide.($CDN 27.00)
This covers a wide range of general concepts and focusses on the use
of Netscape. Very little content on education except for an outdated
URL for ERIC.
Kent, P. (1995). The Complete Idiot's Guide to the World Wide Web. Indianapolis: Alpha books.($CDN 24.00)
This is good for basic concepts and provides background on a number of
different web browsers, but went to press at the same time as Netscape
1.0 so it spends a lot of time on gophers which have pretty well
crawled back into their holes.
Kidder, G. & Harris, S. (1995). HTML Publishing with Internet Assistant. Research Triangle Park,NC: Ventana. ($CDN 42.00 Diskette included)
Even if you don't use the Internet Assistant software to plug in to MS
Word, this is a great reference book for getting
started. Unfortunately, it focuses on Netscape 1.0 applications and
doesn't get into the newer stuff for Netscape 2 and the advanced world
of plug-ins. (And its only a year old!)
Miller, R. & Keeler, E. (1995). Internet Direct: Connecting through SLIP and PPP. New York: MIS Press. ($US 25.00)
If you are reading this on-line, you've probably already solved your
connectivity problems. However no collection of web references would
be complete without something covering the nuts & bolts of setting up
your computer for the internet.
Rimmer, S. (1996). The Internet Graphics Toolkit. New York: McGraw-Hill. ($CAN 50.00 CD-ROM included)
Although the style strains at being "cool", the content provides a
practical guide to producing and incorporating graphics into your web
site.
Stein, L. (1995). How To Set Up and Maintain a World Wide Web Site. Reading, Mass.: Addison-Wesley Publishing Co.
A readable book that covers the behind the scenes workings of a web
site.
Soft Copy References
To keep ahead of the delays in publishing and distribution, publishers
are now simultaneously releasing their books with soft copies on the
web. For example, Macmillan
Publishing's commercial site (they want you to buy the books after
all!) contains links to their on-line bookstore. Here you can find up
to date book listings. Some, such as Que's Digital
Bookshelf, contain complete text of useful internet references.
Others, like the Waite
Group also offer on-line courses.
Examples of a couple of good beginner references are: InterNet
Starter Kit and Special
Edition Using HTML. For the latter, the on-line version is the 1st
Edition (1995), and an ad touts the merits of the new 2nd Edition
(1996) which sells for $US 40 and includes a CD-ROM.
Future Trends
The Internet year is now 26 days long.
The sheer volume of development work conducted around the work is
pushing web technology ahead at ever increasing rates. New browsers to
search the net with will be released with ever increasing frequency,
Plug-ins provide a way for temporary fixes to third party software so
that multimedia development tools can create ever more complex
displays. Programming techniques using Java can make static web pages
come alive and shift processing from the server to the client's
machine. Selective Dissemination of Information provides technique of
narrowcasting specific information to specific users (see Pointcast). Virtual reality
experiences and synchronous audio-graphic conferencing will become
commonplace. A premium will be paid for access to professors in real
time.
Distance Education opportunities via the net will expand and even
though some learners will cummunicate across continents, the bulk will
sign on because of convenience for transportation and
timeshifting.
Educational applications will lag the technology applications as users
try to keep up with the latest tools and technology. Some subject
areas (such as computer studies and business) will see adoption of web
based training rapidly since learners and instructors in those areas
are more likely to have access to the hardware and skills to access
the Internet. A rift will grow between the haves and have nots of the
Internet.
The demand for academic computing support will be insatiable. Just
when educational systems adopt web-based technologies into the core of
their operations, the price of telecomunications will sky-rocket. Most
content will no longer be free, but will be available on a pay for
view basis.
Recreational activities will become available on line and we will all
learn to play the piano through
cyberspace.
Building an on-line Community in British Columbia
The Technology Planning Institute along with the Technology and
Distance Education Branch have been discoursing on-line about the use
of the web and have put together some useful sites.
Of course, the purpose of SEEDS is not just to point you out of the
province. Some of the finest research in networked communities and in
web applications takes place right here in our province. Please enter
your comments or questions in the HyperNews forum. Many of the
Educators who have allowed us to point to their sites have also made
their e-mail addresses available so that they can respond to your
comments.
