Have you ever experienced the process of categorizing information in order to learn something new? What kinds of things that you know now do you think you had to use assimilation or accommodation to learn?
While you may never have seriously thought about these things, a man named Jean Piaget is famous for having researched and pondered them.
Assimilation and Accommodation always go together, we cannot have one without the other.
Assimilation is the process by which a person takes material into their mind from the environment, which may mean changing the evidence of their senses to make it fit. Whereas for accommodation, it is the difference made to one's mind or concepts by the process of assimilation. It is a process of modifying what we already know. We improve and construct the schema.
In addition, I learnt that we can use Tangrams to calculate areas! How nice if I have been exposed to such strategies back then during my school days.
