I am doing a course to help me do more with the children related to how they play. Here is a short video which may help you to understand what Schemas are and how children use different schemas to learn.
Trajectory – up and down and along and back movements
Transporting – Moving items from one place to another
Enveloping – covering things up
Enclosing/containing – putting things into containers
Rotation – things that go round and round
Connection – joining things together
Positioning – putting things in particular places
Transforming – changing things
