About This MicroSim

A draggable spectrum visualization helping students move beyond the simplistic binary of "certain vs. uncertain." As they drag AOK cards along a continuous horizontal axis, they build nuanced thinking about the degrees of confidence achievable in different analytical and creative disciplines.

Lesson Plan

Grade Level

11-12 (IB TOK)

Duration

20 minutes

Prerequisites

  • Familiarity with the six primary Areas of Knowledge.
  • Basic understanding of how empirical data differs from deductive axioms and qualitative interpretations.

Learning Objectives

  • Assess the degree of certainty achievable in different Areas of Knowledge by positioning them on a spectrum and justifying their placement.

Activities

  1. Exploration (5 min): Instruct students to drag the scattered AOK cards (Mathematics, Natural Sciences, Human Sciences, History, The Arts, Ethics) and drop them where they intuitively feel they belong on the spectrum from "Least Certain" to "Most Certain".
  2. Guided Practice (10 min): Use the "Compare My View" mode overlay to display the "Expert View" simultaneously on the screen. Let the class note the discrepancies. Have the students click the cards to read the justification panel below the spectrum. Why do experts usually place Natural Sciences slightly below Mathematics?
  3. Assessment (5 min): Focus on the two lowest certainty AOKs (usually The Arts and Ethics). Have students debate and document their reasoning for which one should be deemed least certain of all.

Assessment

  • Engagement in the placement logic during the sandbox phase.
  • Quality of the comparative argument establishing certainty hierarchies between subjective, interpretive AOKs.

Quiz

Test your understanding of epistemic certainty across AOKs.

1. Why are the Natural Sciences typically placed very high on the certainty spectrum, but still strictly below Mathematics?

  1. Natural Sciences involve too many human participants, lowering their reliability.
  2. Natural Sciences rely on inductive empirical data that can always be overturned by new evidence, whereas Mathematics relies on closed deductive axioms.
  3. Mathematics uses harder equations, making it mathematically impossible to verify.
  4. Natural Sciences primarily rely on aesthetic judgments that cannot be replicated.
Show Answer

The correct answer is B. Mathematics operates in a closed system; once an axiom is established, proofs offer absolute deductive certainty. Natural Sciences operate via induction—observing the real world. No matter how many times we see a law hold true (like gravity), there is an epistemic possibility that a new, anomalous observation could overturn it tomorrow, preventing absolute 100% certainty.
