Cognitive Models of School Learning
Organized on Two Levels Fundamental properties of mental
activity Conceptual issues in teaching and
learning
Copyright © Houghton Mifflin Company. All rights reserved.
2-3
Fundamental Properties Represented as Information Processing
Describe movement and manipulation of information within the human information processing system.
How might characteristics of the system inform instructional decisions?

2-4
Components of Information Processing System
Stores - hold information Processes - mental actions Executive mechanism - control and
evaluate
Copyright © Houghton Mifflin Company. All rights reserved.
2-5
Stores
Sensory Memory - less than a second
Short Term Memory - consciousness
Long Term Memory - permanent storage
Copyright © Houghton Mifflin Company. All rights reserved.
2-6
Short Term Memory
Equivalent to consciousness - information presently in your awareness
Sometimes called working memory - reference is to this store as the location of activities of learning and thinking
Operates with duration and capacity limits
Copyright © Houghton Mifflin Company. All rights reserved.
2-7
Short Term Memory Limits Duration and capacity limits
establish some educational goals Automatic word recognition Keyboarding speed
Efficient practice involving drill software may be solution
Skills are mastered so capacity is available for higher level skills (reading comprehension, writing)

2-8
Long Term Memory
Stored products of learning and experience Declarative knowledge - knowing
that Procedural knowledge - knowing
how Episodic knowledge -
representation of an experience
Copyright © Houghton Mifflin Company. All rights reserved.
2-9
Episodic Memory
Is storing experiences rather than abstracted concepts, principles, etc. useful?
Experts appear to use experiences as well as abstractions. Have done the mental work of
indexing experiences.

Long Term Memory Is Linked Contents of LTM are linked Pattern of links is unique to
individual learner Links are important in recall and in
what additional information “comes to mind.”
Effective learning requires both content and meaningful links.

2-11
Processes - The Actions of Learning and Thinking Some general categories of
activities: Attend to - maintain in
consciousness Link - connect units of information Elaborate - act on information to
produce knowledge through connection and inferencing.
Evaluate - determine if mental state is as desired or expected.

Metacognition
Accounts for the adaptive and strategic nature of learning and thinking.
Copyright © Houghton Mifflin Company. All rights reserved.
2-13
Metacognition Knowledge Metacognitive knowledge -
awareness of task requirements and personal characteristics What does it take to perform this
task? Why is this task difficult or easy for
me? Example - what is demanded in an
essay vs. multiple-choice test?

2-14
Metacognitive Control Functions Planning Regulating Evaluating
Is this making sense? (reading)
Copyright © Houghton Mifflin Company. All rights reserved.
2-15
Learner Control Vs. Computer Control If metacognitive skills are suspect,
should control of learning experiences be turned over to a computer? Determine number of practice
problems Determine when to go on to new
material Learner control with advisement as
a compromise.

Conceptual Models of School Learning A conceptual focus on:
Instructional goals Preferred instructional practices Ideal student behaviors

2-17
Conceptual Models of School Learning Meaningful learning (Ausubel) Generative learning (Wittrock) Constructivism
Copyright © Houghton Mifflin Company. All rights reserved.
2-18
Meaningful Learning Meaningful learning occurs when
new experiences are related to what is already known.
Rote learning occurs when information is stored in isolation

2-19
Assumptions of Meaningful Learning Learner has knowledge relevant to
new experiences. Learner is motivated to develop
connections between new experiences and what is known.

Hands On ≠ Minds On
Important to note that not all activity promotes meaningful learning
Copyright © Houghton Mifflin Company. All rights reserved.
2-23
Generative Learning - Wittrock Importance of connection between
new experiences and existing knowledge
External tasks can influence mental activity

Constructivism
No single “official” version Most commonly accepted
principles Understanding is constructed by
each individual Learning serves an adaptive
function

2-25
Implications of Constructivist Principles Student responsible for own
learning Context influences what is
perceived as useful Purpose of education is to build
useful personal knowledge
Copyright © Houghton Mifflin Company. All rights reserved.
2-26
Common Conceptual Themes Learning is active Learning is adaptive Learning builds on what is known
Copyright © Houghton Mifflin Company. All rights reserved.
2-27
Implications for Practice Concept of authentic activities Problem of inert knowledge Higher order thinking Learning in a social context
Copyright © Houghton Mifflin Company. All rights reserved.
2-28
Authentic Activities
Ordinary practices of a culture How can learners experience the
role of a practitioner?

2-29
Inert Knowledge
Useful knowledge that is not activated
How can classroom experiences challenge naïve beliefs?

2-30
Higher-Order Thinking Sounds good -- what is it? Criteria
Complex - entire process may not be clear from beginning
Effortful - motivated thinking Self-regulated - planning and
monitoring Often requires judgment - evaluate
alternatives

“opportunities get taken” Learning by constructing
multimedia
