Challenging Questions

• What scientific knowledge can be used to inform the design of technology-supported learning experiences?

• What is the scientific basis for (pick your favorite buzzword) “social constructivism,” etc?

Assumption #2

• Pedagogy is more important than technology

What scientific principles should drive

the design of learning experiences?

An abbreviated history of psychology as applied to learning

• Associationism/Behaviorism

• “You have a brain, but we don’t care what it’s doing. We care about observable behavior.”

An abbreviated history of psychology as applied to learning

• Early cognitive psychology

• “Your brain is important, and it works like a digital computer.”

An abbreviated history of psychology as applied to learning

• Current cognitive psychology

• “Your brain is a complex product of evolution, and its strengths and weaknesses are the opposite of those of a digital computer.”

An abbreviated history of psychology as applied to learning

• Social constructivism

• “Each person’s knowledge is uniquely constructed on a foundation of prior knowledge and experience, and validated through participation in a community of learner-practitioners.”

Areas within cognitive psychology

• Cognitive neuroscience

• Attention, perception

• Memory

• Problem solving

• Judgment and decision making

• Creativity

Cognitive neuroscience

• The brain is a highly interconnected neural network; knowledge is stored in patterns of connection strengths among neurons

Neural network learning

Neural network recall

Memory

• Short-term (working) memory is small• Long-term memory is unlimited• Astounding visual pattern memory• Partial retrieval of knowledge is common• Activation of prior knowledge enhances encoding

and retrieval of new information• “Encoding specificity”: similarity of context at

learning and at recall increases retrieval

Problem solving

• Expert-novice differences in categorizing and solving problems

• Poor transfer of learning to different types of problems

• Prior misconceptions of novices hinder new learning

• Most real-world problems are “ill-defined.”• Expertise and “automaticity” have some

disadvantages

Judgment and decision making

• JDM: making decisions under uncertainty, or based on personal preferences

• Shortcuts, heuristics, “satisficing”

• Modest “metacognition:” the ability to monitor, control, and evaluate the quality of one’s own judgments; overconfidence

Other research findings

• “flow” experiences (challenging situation, immediate feedback, high engagement) are highly satisfying

• motivation -> time on task -> achievement

Findings and principles

• FINDING: Activation of prior knowledge enhances encoding and retrieval of new information

• Prior misconceptions of novices hinder new learning

• PRINCIPLE: Engage learners in reviewing what they already know before new information is introduced; probe for misconceptions.

• EXAMPLES; questions about prior knowledge; problems requiring prior knowledge

Findings and principles

• FINDING: “Encoding specificity”: similarity of context at learning and at recall increases retrieval

• PRINCIPLE: Organize the content of learning experiences around application themes

• EXAMPLE: “clinical presentation” curricula in medical education

Findings and principles

• FINDING: Expert-novice differences in categorizing and solving problems

• PRINCIPLE: Provide students with early exposure to expert approaches to problems; design learning experiences to foster expert-like thinking

Findings and principles

• FINDING: Poor transfer of learning to different types of problems

• Most real-world problems are “ill-defined.”• PRINCIPLE: Provide many problems and “mini-

cases” to promote generalization and transfer.• EXAMPLE: “what if one variable changed”

questions; applications of “cognitive flexibility theory” (Rand Spiro) to film analysis, medicine

Findings and principles

• FINDING: Modest “metacognition”: the ability to monitor, control, and evaluate the quality of one’s own judgments; overconfidence (in learning or judgment).

• PRINCIPLE: Build self-assessment into learning, along with expert feedback

• EXAMPLE: in-class “voting” on answers to problems; confidence-weighted test questions; self-assessments in learning portfolios

Findings and principles

• FINDING: “flow” experiences are highly satisfying

• motivation -> time on task -> achievement

• PRINCIPLE: Use authentic, engaging simulations/cases/problems to drive learning

• COROLLARY: Don’t assume that high-fidelity simulations are required (e.g., paper-based PBL)

Model of optimal learning

Challenging Questions

• What scientific knowledge can be used to inform the design of technology-supported learning experiences?

• What is the scientific basis for (pick your favorite buzzword) “social constructivism,” etc?
