Concept:Constructive teaching uses both examples and non-examples to clarify concepts and deepen understanding.
Explanation:Examples show the correct features of a concept.
Non-examples show what the concept is not.
Comparing both helps students identify key attributes and boundaries.
This method prevents confusion and builds strong conceptual knowledge.
Using only examples or only non-examples gives an incomplete picture.
A constructive teacher therefore includes both in her lessons.
This promotes critical thinking and better retention.
Answer:A. Gives both examples and non-examples in her classroom.
