All knowledge is built from Concepts and Propositions

A Theory of A Theory of KnowledgeKnowledge
Concept:
A perceived regularity in events or objects, or records of events or objects, designated by a label:
LifeCellBlueShip
DemocracyUnicorn
Proposition:
Two or more concepts combined to form a statement about something: a basic unit of meaning or expression
•e.g., living things are composed of cells
•e.g., the ship was blue

David Ausubel (1968)
If I had to reduce all of educational psychology to just one principle I would say this: The most important single factor influencing learning is what the learner already knows. Ascertain this and teach him accordingly.*
* Epigraph, Educational Psychology: A cognitive view
Key ideas:
1. Distinction between rote and meaningful learning.
2. In the process of meaningful learning, people construct meanings for concepts and propositions based on experiences, building up their knowledge structure.
Traditional Model of Instruction
This process is called “assimilation”
David Ausubel’s Theory of David Ausubel’s Theory of LearningLearning
Meaningful Learning involves changing one’s current knowledge as a result of the comprehension of new knowledge.
1. Progressive differentiation of concepts and relations over time.
2. Superordination of concepts under more general, more inclusive concepts.
David Ausubel’s Theory of David Ausubel’s Theory of LearningLearning
Four fundamental processes that lead to assimilation:
3. Subsumption of new concepts into existing, more general concepts and propositions.
4. Integrative reconciliation to achieve coherence and consistency over time.
David Ausubel’s Theory of David Ausubel’s Theory of LearningLearning
Learning may vary from highly rote to highly meaningful
Toward:
Constructivist epistemology holds that knowledge is a human construction and evolves over time
Away from:
Positivist epistemology holds that knowledge derives from empirical observation and is “unfettered” by varying human ideas over time
New epistemological thinking

Why use Concept Maps?
To assess existing knowledge prior to beginning a teaching/learning session
As a reflective practice to create and make explicit mental linkages surrounding a concept

How Do Concept Maps Expedite Learning?
Provide for Concise Organised Expression of the Knowledge Inherent in Textual Source Material Concepts (Classes/Entities) Attributes/Properties (of concepts/entities) Relations (between concepts/entities)
Learning Occurs During the Process of Creating and Refining the Concept Map
Learning Occurs During Iterative (Repeated) Study/Review of the Concept Map with Reference Back to the Source Material and Associated Updates to the Concept Map

Some Additional Advice
Stick With It! Must Do It Several Times for It to Seem Natural Get to the Point Where You Are Uncomfortable
Studying Without Using Concept Maps Think Hard and Ask Yourself Questions!
What Does a Passage or Paragraph in the Source Material Mean?
Is the Concept Map Complete? Is the Concept Map Coherent? Does It Make Sense? Don’t Quit Until You Have Figured It Out and You
Understand Your Concept Map
