About This MicroSim

Explore how the three types of cognitive load compete for limited working memory capacity.

Learning Objectives

  1. Explain how intrinsic, extraneous, and germane load relate to working memory
  2. Predict when cognitive overload will occur
  3. Understand why reducing extraneous load improves learning

How to Use

  1. Adjust Concept Complexity: Move the slider to change intrinsic load (material difficulty)
  2. Adjust Interface Confusion: Move the slider to change extraneous load (design waste)
  3. Watch the Beaker: See how loads fill the capacity container
  4. Monitor the Lightbulb: Brightness shows learning effectiveness
  5. Try Presets: Click preset buttons to see different scenarios

Key Concepts

Load Type Source Strategy
Intrinsic Concept complexity Accept it (can sequence learning)
Extraneous Poor design Minimize it (clean interface)
Germane Actual learning Maximize it (goal of instruction)

Lesson Plan

Grade Level: College Duration: 15-20 minutes Bloom's Level: Understand (L2)

Activities

  1. Exploration (5 min): Try each preset and observe the results
  2. Prediction (5 min): Before moving sliders, predict what will happen
  3. Design Challenge (5 min): Find settings that maximize learning
  4. Discussion (5 min): How does this apply to MicroSim design?

Assessment

Students demonstrate understanding by:

  • Explaining why extraneous load is the "enemy"
  • Identifying when overload occurs
  • Suggesting design changes to reduce extraneous load
