Assimilation

(Posner et al., 1982) in the journal Science Education 66(2), 211-227
 * //Assimilation//** – use existing concepts to deal with new phenomena (Posner pg. 212)

Justifying or rationalizing new and possibly confusing information or ideas using existing theoretical framework

diSessa (2006) might refers to using intuitive knowledge to teach (like p-prims); this information would be easily assimilated in the conceptual change model, rather than the much more difficult accommodation

-The process of incorporating new information to their existing knowledge structures when students encounter with new evidence. Posner called this process as assimilation. Duit (2003) called this as "weak knowledge structuring".
