====In problem solving====
Much of the research regarding expertise involves the studies of how experts and novices differ in solving problems.{{sfn|Chi|Glasser|Rees|1982}} Mathematics{{Sfn|Sweller|Mawer|Ward|1983}} and physics{{Sfn|Chi|Feltovich|Glaser|1981}} are common domains for these studies.

One of the most cited works in this area examines how experts (PhD students in physics) and novices (undergraduate students that completed one semester of mechanics) categorize and represent physics problems. They found that novices sort problems into categories based upon surface features (e.g., keywords in the problem statement or visual configurations of the objects depicted). Experts, however, categorize problems based upon their deep structures (i.e., the main physics principle used to solve the problem).<ref name=":3">Chi et al. 1981</ref>

Their findings also suggest that while the schemas of both novices and experts are activated by the same features of a problem statement, the experts' schemas contain more procedural knowledge which aid in determining which principle to apply, and novices' schemas contain mostly declarative knowledge which do not aid in determining methods for solution.<ref name=":3" />
