Introduction
This position aims to encourage discussion between WWW providers of educational
material and researchers in the field of educational technology. This paper
is still a early draft and I am afraid it will retain that status for a
while
Introductory reference material in the Appendix sections has awful
very rough draft status. It is useful only as far as it points to some
real reading. The table of Contents is in a separate file (by pure laziness)
for the moment). Everything is straight Framemaker to html translation
without modifications...)
1 Introduction
What is known about human learning relevant for the design of educational
material? How should this knowledge be used in the context of more specific
educational goals and WWW-supported learning & teaching activities?
Generally speaking there are two important statements about learning and
instruction:
-
One learns by doing something (psychology)
-
One learns by pursuing an instructional goal (education sciences)
The learning environment designer must take into account both perspectives.
WWW-based courseware must not restrict itself to delivery of educational
content. It must be grounded in some model of instruction and learning.
Many possibilities exist and haven proven to be effective. However, each
paradigm works under certain conditions in certain situations using some
set of specific educational technology. For example, it can easily be argued
that a good book is better than hypertext version of that book (why do
people always print out things?). Also, general rules can be formulated
such as "learning without doing is pretty useless in most domains". Consider
the following questions:
-
Would you take the plane if you knew that the pilot has read all the documentation
about flying and successfully passed examination testing his knowledge?
-
Would you take a plane if you knew that the pilot has been trained with
Microsoft flight simulator? Which one do trust better?
-
Would you take an Airbus if you knew that the pilot has been trained on
a B-737 and has read the WWW multimedia Airbus documentation?
-
If you had to teach flying an Airbus, would you take a would-be pilot and
show him how to fly "hands-on"?(1)
Some basic misconceptions about learning have to avoided: Reading or seeing
does not imply much learning. Even being able to recall knowledge does
not mean being able to apply knowledge. Efficiency is not measured by mastery
of the exercises and tests of a courseware tool, but my mastery of the
task. Also be aware of more subtle knowledge transfer problems: Even "micro"-competencies
such as operating an Airbus vs. a Boing or programming in C instead of
Pascal are difficult to teach. If more abstract things like "programming"
instead of just C programming have to be learned, special teaching strategies
have to be used (such exercising skills in variating contexts. Lastly,
the complexity of a learning environment must be adapted to the learners
skills (Would you teach C as an introductory programming language)?
2 Some Learning Theory Background
Summary
Learning appears to be a complex matter. No doubt that this is the reason
why all the various branches of learning theory do not even view the problem
from a same angle. However, all academic traditions do provide the learning
environment designer with important key ideas:
-
Learning must take place within optional external "conditioning" (behaviorism)
-
Learning is related to active problem solving and involves integration,
construction and compilation of new content (cognitivism)
-
Learning is constrained by human cognitive capacities (experimental psychology,
HCI theory)
3 How is courseware related to instruction?
Courseware engineering is concerned with electronic learning environments.
Such an environment is a combined system involving tasks, agents, courseware
products, etc. which is aimed at supporting learning processes and in which
learning takes place mostly in interaction between learners, courseware
products, other tools, and to a lesser degree tutors (human or artificial).
Courseware is always a combination of elements (cf. de Dinan & van
Shaik 93: 193), such as:
-
textual material (including textual representations)
-
simulation models,
-
exercises
-
problems
-
feedback information, etc.
Each type of courseware architecture organizes those resources in various
ways. How complete are the materials supplied to the learner with respect
to the information and support needed by the learner to achieve an instructional
goal? Several ways of tackling this problem have been proposed.
We shall briefly introduce some ideas from (1) Instructional Design
and from (2) Advanced Learning Environment Research.
4 Instructional Design Theory: Sequencing & Chunking
of Educational Material
Summary (bad!)
Instructional Design Theory provides detailed prescription on how to organize
teaching and learning at the global (curricula), lesson and task level.
Most work is also grounded in some learning theory. Despite and maybe also
because of the level of details those approaches attempt to formalize instruction
their practical use is often debated. Some argument against reading much
instructional design theory is that a good teacher with good practice intuitively
knows and uses things like Gagné's steps.
Most people agree that instruction needs principles, however some
researchers feel that instructional theory should not just be grounded
in learning theory but BE applied learning theory and to implement optimal
learning conditions according to what we know about learning. This is the
way most research in Advanced Learning Systems operates.
5 Research on Advanced Learning Environments
Summary
-
The Learner must be active
-
A learning environment should be designed as powerful dedicated working
environments. It must be rich and complex reflecting the essential properties
of what has to be learned.
-
The environment must be structured. If the richness of a learning environment
is a quality, its complexity may reduce learning. It must provide optimal
learning conditions in function of the learner's stage of knowledge.
-
Learning environments should be designed as hierarchical knowledge base
generators
-
Learning environments should present knowledge as a communication system.
A learner must interact with agents, tutors.
At the current state of the WWW technology, it is not possible to implement
this kind of advanced learning environment (without making use of external
clients). However, there are points that WWW based courseware can adopt.
6 What learning activity can we do with the Web?
Here is a (short) list of different kinds of computational learning environments
in use. They represetn different learning paradigms and can be classified
along several axes like "Instruction - Learning", "External - Internal
Control". Each are still appropriate for certain kinds of learning.
-
Programmed Instruction (little step by step transfer of content)
-
Computer Assisted Instruction (Drills & Tutorials)
-
Intelligent Computer Assisted Instruction (ITS Tutorials)
-
Computer Based Learning (Simulations, Hypertext & Microworlds)
-
Intelligent Learning Environments (Microworlds + tutors, helpers, experts)
-
Cognitive Learning Support Environments (some hypertexts)
-
Knowledge Construction & Environments & Intellectual Toolkits
Now match that to those more technical items:
-
Information servers to look up information (manuals, books, expositions,
bibliographies, programs, etc.)
-
Distribute educational material (texts, programs)
-
Provide curricula & guidance to lessons and exercises in hypertext
format.
-
Implement collaborative work (dynamic hypertext, "News like conferencing
system", co-writing)
-
Implement Jigsaw puzzles
-
Question & Answering, (tests, Skinner & Bloom type of learning
to some extent)
-
Interface to local clients (e.g. simulations, programming environments,
tutors, etc.)
-
The same thing over the web (e.g. have intelligent nodes, cf. Mallery)
-
....
The WWW, specially in conjunction with external local or server-side clients
offers a lot of possibilities. But not everything can be done and it is
important not to use in inappropriate learning paradigm for a given educational
goal.
7 Educational Hypermedia
Integration of Hypermedia
There are 3 aspects:
-
Integration into a learning environment setup: What role in learning &
teaching does hypermedia have? (see also "What
learning activity can we do with the Web?" on page 6) What other tools
do we need?
-
Integration into a learning environment architecture: How can we make integrate
hypermedia with other computational learning tools?
-
Computational integration with other programs: How can we build achieve
tight integration?
8 Courseware engineering & the learning environment
In more simple and technical terms, courseware engineering (cf. De Dian
& van Schaik 93:193) is concerned with:
-
transferring educational information
-
organizing pedagogically optimized access to this information via an appropriate
interface and structuring of the material
-
implementation of instructional tactics, e.g.:
-
giving examples
-
multiple choice questions
-
asking the student to perform a task, etc.
-
telling the student what learning strategy to adopt with some material
-
....
-
implementation of instructional strategies, i.e. sequencing of teaching
materials
Furthermore, Courseware engineering is not everything. Courseware alone
rarely constitutes the full learning environment. Authors of Instructional
Material on the Web should be aware of the following:
-
Teaching and learning involves a learning environment. It is not good enough
to hypertextify a text or implement form-based tests. Good Web based courseware
is more global in design. Not everything must be built into html or server-side
scripts, but somehow instructional tactics & strategies as well as
learning strategies have to be "put" upon the learner or communicated to
the learner. Last, but not least he needs assistance and very often cooperation
with other learners.
-
Delivery of instructional text (multimedia and hypermedia) has be structured
according to some pedagogical & learning strategies. If the learner
has to discover everything himself - fine - but tell him so!
9 So what can we do with the Web?
In discussing the role of technological support in education,
Sandberg (94:225) identifies the components of a (technologically rich)
learning environment (see "Overview
of the Learning Environment (Sandberg 94:225)" on page 9). These components
must all be there in order to optimize learning. However, they can be "implemented"
in many different ways. Each component has functionalities for which we
should insure:
-
teacher: His role is provide something between loose guidance & direct
instruction. It can be a human agent (present or distant) or an intelligent
agent. He provides information from the curriculum to the task level.
-
monitor: The Monitor ensures that something is learner. A role taken by
either the teacher, the learner (self-control) or by some program.
-
fellow learners: Improve the learning process (some research tries to implement
artificial ones)
-
learning material: Learning material contains what has to be learned in
a very broad sense (e.g. knowing what, knowing how). It can be computational
in various ways (exploratory hypertext, lesson & task oriented hypertext,
simulation software, task solving environments, etc.
-
External info sources: All kinds of information which is not directly stored
in the learning material (e.g. additional material, handbooks, manuals,
etc.)
-
tools: Everything which may help the learning process other then the learning
material (e.g. calculators, communication software, etc.)
Let's examine the Table 1,

The question whether to fly with an Airbus at all, concerns more HCI but
there is an interesting point concerning transfer of something learned:
Would you drive a car without steering wheel (using sticks or something
like that instead)?
