According to How Learning Works: Seven Research-Based Principles for Smart Teaching, an important difference between the knowledge of experts and novices is “the number or density of connections among the concepts, facts, and skills they know” (Ambrose, Bridges, DiPietro, Lovett, and Norman 2010, p. 49). Experts have dense weaves of connections between all of the facts and information they know, and novices have sparse and incomplete ones.
