Accommodation

(Posner et al., 1982) in the journal Science Education 66(2), 211-227
 * //Accommodation//** – replace or reorganize central concepts (Posner pg. 212)

- Takes the initial changes found in an assimilation and turns them into a more concrete idea - A restructuring of information, not just an addition of new facts or ideas -While accomodation is a radical change, it does not have to be a quick or sudden change, especially because student knowledge is more fragmentary rather than clearly organized so true Aha! moments are rare.

According to Pintrich, Marx, and Boyle, the conceptual change model argues that four different conditions must be met in order for accommodation to take place: 1. "Dissatisfaction with current conceptions" 2. New concept is intelligible 3. New concept is plausible 4. Must be fruitful (possess "explanatory power and/or suggest new areas for investigation") (p. 172).

Duit (2003) called this accommodation process as "strong or radical knowledge structuring" because this process requires students to essentially change or replace their knowledge structures.
