The Nature of Knowledge

Epistemology, or the study of knowledge, asks students to consider what it means to 'know' something. This topic moves students beyond the mere acquisition of facts to an investigation of truth, belief, and justification. In the Irish curriculum, this aligns with the NCCA's emphasis on critical thinking and the ability to evaluate the reliability of different sources of information.

Think-Pair-Share20 min · Pairs

Think-Pair-Share: The Knowledge Filter

Students are given three statements: one they believe, one they know, and one they feel is true. In pairs, they must explain the difference in 'certainty' for each and what evidence would be needed to move a belief into the 'knowledge' category.

Inquiry Circle: The Truth Detectives

Groups are given 'mystery boxes' with hidden objects. They must use different ways of knowing (shaking, smelling, using a magnet) to form a belief about what is inside. They then discuss as a class whether they 'know' the contents or just 'strongly believe' based on the evidence.

Can we ever be absolutely certain?

A few notes on teaching this unit


Watch Out for These Misconceptions

  • If I believe it strongly enough, it counts as knowledge.

    Students often confuse sincerity with truth. Active discussion about things people used to believe strongly (like the Earth being flat) helps them see that knowledge requires an objective connection to reality, not just a strong feeling.

  • Knowledge is just a collection of facts.

    Students may think 'knowing' is just memorization. By using scenarios where facts are right but the reasoning is wrong, students learn that knowledge also requires 'justification', having the right reasons for what you believe.
