Now I sh ould like to show that learn in g is possible in the case o f these logical-mathematical structures, but on one con dition—that is, th at the st r u ct u r e wh ich you w an t t o t each t o the su bject s can be supported by simpler, more elementary, logical- math ematical structures.
This is similar to the process for teaching complex mathematical topics; CRA- Concrete, representational, abstract.
