I. types of CAL software,II. hypermedia/multimedia
environments,III. authoring languages,IV. design considerations,V. a critical view of
CAL/multimedia.
I. Types of CAL I. Types of CAL SoftwareSoftware
•drill and practice•games•simulations• tutorials• tools• (hypermedia)• (CMI software; e.g.. tests)
categorizing is difficult:
imagine a “space travel game” in a“hyper environment” with atutorial component.
• • drill and practicedrill and practice
Typically, drill and practiceactivities are supplementaryto the “normal” teaching process.
• • drill and practicedrill and practice
Can be thought of as a “flash card”system of the stimulus-responsemodel.
• • simulationssimulationsThe University of Illinois hassuccessfully provided computer-driven “dry” chemistry labs.
• • tutorialstutorials
Self-paced, where the computeracts as an infinitely-patient,all-wise tutor.
Is this guy slow, or what??
Typically a good tutorial will have astructure(s) as follows:
give information test
giveinfo.. . .
remediate
OK
(needs help)
spreadsheet programs statistics packages hypermedia software desktop publishing
software presentation software CAD software etc.
• examples of tools
q
hypermedia can be thought of as “chunks” of information (nodes),stored in a structure, and accessed by links (buttons).
• • hypertexthypertext
Textual information, structuredby use of links and nodes.
Here is some exampletext which is going tobe shrunk down to asize which is barelyrecognisable; good toobecause then my poorspelling won’t berecognised. Now, Ihave run out of exampletext. Oh well; so what?

• • hypermediahypermedia
Like hypertext, but includingsound, video, and/or animation.

• • multimediamultimedia
Involves more than one medium(>2 really, since most literaturecontains graphics and text).
• • multimediamultimedia
Involves the use of sound,animation, and/or videoas well as text and graphics.
Even Ted Nelson said he didn’tknow the difference betweenhypermedia and multimedia.
• • multimediamultimedia
11
11Educational Multimedia and Hypermedia Conference,June 1994, Vancouver. [Ted Nelson coined the term hypertext (“non-sequential writing”)].
• • multimediamultimedia
Interactive multimedia is theincorporation of multimedia withhuman-computer interaction.
• • multimediamultimedia
Interactive multimedia provides an obvious educational advantage over current broadcasting & publishing which is passive.

Metaphors abound.A computer screen ofinformation can be aslide, a page, a card,a node, whatever...
Possible applications of less complexdesigns include electronic books, andinformation/ training kiosks.
Hyperdesigns give the user opportunity for:
•more control, but• require careful planning and
analysis.

Packages exist which allow the creation of CAL packages by non-computer programmers.

a critical view:
3. Too much attention is paid to appearance (esp. graphics) and not enough to educational issues.
