Description

Discrepant events are demonstrations, observations, or scenarios that violate learner expectations in a noticeable way. They are useful when the instructional goal is to provoke rethinking, explanation, and conceptual change.

Design Implications

Context

Requirements

• An event that clearly contradicts an expected outcome
• A follow-up prompt that asks learners to explain the mismatch

Constraints

• Without debrief, surprise alone may entertain more than teach

Target Learning Goals

• Surface misconceptions and create readiness for explanation revision.

Affordances

• Cognitive Disequilibrium
• Cognitive Flexibility
• Error Analysis

Claims

• External disequilibrium level systematically influences subsequent changes in internal disequilibrium: discrepant conditions increase mixture among low mix subjects and decrease it among high mix subjects [~W]
• Eleven-month-old infants learn a new object-sound mapping after a surprising core knowledge violation but not after an expected outcome [+W]
• Infants' exploratory behavior after a core knowledge violation is tailored to the type of violation seen [+W]
• Discrepant peer feedback leads to more transitions between feedback and essay, but only for students who report the discrepancy afterwards [~W]

Examples
