Web-based Learning
World Wide Web (WWW)
Computer-based
network
of
information
resources
that
combines text and multimedia.
The information on the World
Wide Web can be accessed and
searched through the Internet, a
global computer network. The
World Wide Web is often referred
to simply as “the Web.”

Internet Topology
Internet Topology
The Internet and the
Web are each a series of
interconnected computer
networks. Personal
computers or
workstations are
connected to a Local
Area Network (LAN)
either by a dial-up
connection through a
modem and standard
phone line, or by being
directly wired into the
LAN. Bridges and hubs
link multiple networks to
each other. Routers
transmit data through
networks and determine
the best path of
transmission.

Distance Learning

Communications
• E-mail: to send learners new
information
• Bulletin boards: continue class
discussion outside classroom
• Chat rooms: as multi-user domains
Researchers: electronic journals
 Delivery of learning materials

Design and Development of Multimedia Courseware
Web-based Learning
Integrating & managing learning
and instruction
Central place of resources
 Specific software: WebCT, TopClass

• Allow instructors to build a site easily
with course syllabus, assignments,
notes, reference material, exam,
general information


Other methodologies may be used but common is
hypermedia.
Navigation
• Hyperlinks, buttons, menus: primary use
• Indices, table of content, maps, bookmarks: specific use
• Commercial search engines (specific to the web)

Orientation
• Different orientation in called up web sites
• Rules of thumb






Good design
Site maps
Bring others’ websites into frames (or windows)
Printed guides
Study called up sites well
Hypermedia formats
• Most suitable is encyclopedia reference
• Games, edutainment demands extensive programming: Java


Browsers
•



•
•
•
These are software on client machine that interpret material on the web: MS
Internet Explorer, Netscape Navigator.
Web material should be browser independent
User customization of browsers affects designers specifications
Material may change browser setting and restore on exit
•
•
•
Type of link: dial up or leased line
Bandwith
Content: video, animation, and audio
•
•
Only if appropriate
Use suitable formats: still graphics (jpeg, gif), video (mpeg), audio (mp3)
•
•
•
•
•
Small number of windows
Minimum scrolling
Easy exit of windows
Designers navigational buttons vs browser’s counterparts
Use of several frames : independent scrolling
Speed
Multimedia content
Visual layout

Factors in web-based learning..

Interactivity
• Web is not usually designed for this
• Storage of data difficult (with HTML)
• Use of Java, Javascript, Java server pages to
achieve this

User control
•
•
•
•
•
Forward progress, pace, and exiting
Pausing, continuing, repeating of multimedia
Control of audio volume
Searching and bookmarking
Access to other sites and services


Stability
• Stability of other websites: updating,
disappearance
• Need of additional software (plug-ins) to view
video and animation.



Privacy, security and safety
Storing data: copyright issues
Instructional support
• Motivation, creativity, thinking, reflection
