Implications of cognitivism for learning software
supporting the learner’s activity
COSC 4126 Supporting the learner
Supporting learner activity Stages of content mastery
1. Presenting information – from instructor or program to learner
2. Guidance – learner performs partially supported 3. Practice – fluency develops4. Assessment – measure performance rel to
standard or group?-For marks or for evaluation of instruction or for deciding what’s next (eg in mastery learning)

Learning stages and game structure
1. presentation what means, strategies or formats?

Project analysis
First design questions: which stage(s) of learning ‘dominate’
your topic? which stage(s) do you want to implement
in your project?
COSC 4126 Supporting the learner
How does cognitivism influence design of learning software?
model of learning process implications for learning activities
COSC 4126 Supporting the learner
Cognitivism – learning principles
perception from senses
model in memory

Organizing knowledge for learning
how to make assimilation / accommodation ‘efficient’
COSC 4126 Supporting the learner
Assimilation and Accommodation
A basic organization*:
Epitome plus Elaborations
where to start how to proceed
*strongly influenced by the work of Charles Reigeluth and David Merrill
COSC 4126 Supporting the learner
Epitome
is minimal complete concrete accessible
background interesting
is not abstract atypical
COSC 4126 Supporting the learner
Elaborations retain structure of epitome elaborate on aspects of epitome content introduce background as necessary
facts, notation, jargon develop experience to support induction
(assimilation; accommodation) to concepts, principles, theories
philosophy 101
COSC 4126 Supporting the learner
Example – solving Rubik’s cube
20 cubes to locate correctly
epitome: locate first cube(easy)
19 elaborations: locate next cube(harder and harder)
COSC 4126 Supporting the learner
Epitome – locate first cube (1)
1. find edge cube with top and front colours
2. move that cube to bottom front
COSC 4126 Supporting the learner
Epitome – locate first cube (2)
3a. if front colour matches, rotate to top
COSC 4126 Supporting the learner
Epitome – locate first cube (3)
3b. if front colour does not match, rotate to side, rotate up, rotate to top
COSC 4126 Supporting the learner
Epitome
is minimal - easiest cube to locate complete – extent, alternatives concrete accessible – minimal jargon and
notation background – some familiarity with
Rubik’s cube interesting – is relevant, poses a
problem, shows progress
is not abstract atypical
COSC 4126 Supporting the learner
Elaborations – place other cubes
retain structure of epitome – place a cube elaborate on aspects of epitome content
longer sequences, more alternatives, temporary displacement of located cubes
introduce background as necessary terminology for cube parts, notation for
rotations, important rotation sequences develop experience to support induction to
concepts, principles, theories
COSC 4126 Supporting the learner
So...
That was an epitome
of an instructional design,
Now,
here’s an elaboration...
COSC 4126 Supporting the learner
Structuring knowledge for learning
An elaborated organization:
Epitome plus Elaborations
1.Create an organizing structure of the knowledge
2.Identify an epitome and an elaboration sequence
COSC 4126 Supporting the learner
Example – organizing structure
20 cubes to locate correctly
Locate cubes
Top layer Middle layer Bottom layer
Edge cubes
Edge cubes
Edge cubes
Corner cubes
Corner cubes
1st 2,3 4th etc...
COSC 4126 Supporting the learner
Example – epitome and elaboration sequence
Locate cubes
Top layer Middle layer Bottom layer
Edge cubes
Edge cubes
Edge cubes
Corner cubes
Corner cubes
1st 2,3 4th etc...

Organizing Structure of knowledge
historical developmentorexpert knowledge
are probably not the best
organizing structures for learning
COSC 4126 Supporting the learner
Organizing Structure of knowledge
1. Decide most important form of knowledge. (e.g., procedural for Rubik’s cube)
2. Create organizing structure of knowledge of that form
3. Add other forms where first required
COSC 4126 Supporting the learner
Procedural organizing structure
Locate cubes
Top layer Middle layer Bottom layer
Edge cubes
Edge cubes
Edge cubes
Corner cubes
Corner cubes
1st 2,3 4th etc...
Other knowledgeLayer notation Rotation notation Cube mechanics
Cube lore Rotation sequences
Cube mathematics
COSC 4126 Supporting the learner
Organizing Structure of knowledge
Some possible organizing forms Procedural Systemic (part-of, type-of, instance-of) Theoretical (principles, laws, theories) Tabular
COSC 4126 Supporting the learner
Project analysis
Second design task: organize the knowledge to be
presented decide the dominant knowledge type structure the knowledge of that type identify and locate supporting types of
knowledge define assumed user background
COSC 4126 Supporting the learner
Epitome and Elaboration Sequence
1. Many sequences are possible from a knowledge structure
2. Main constraint: prerequisites3. Different sequences appropriate for
different types of instruction4. Who controls the sequence? learner??
COSC 4126 Supporting the learner
Cognitivism – implications for teaching and learning learner control of sequence active participation increasingly complex microworlds (LOGO) multiple points of view/representations metacognition simulations tools metaphors reflection – thinking about thinking
COSC 4126 Supporting the learner
Cognitivism Example: Thinkertools (White and Frederiksen)
premise: ‘real world’ intuitions are too strong to overcome main problem is friction
interferes with understanding of force, motion, acceleration, momentum
hypothesis: build intuition with virtual experience ‘air puck’ world
