Scaffolding

Explanation:

Scaffolding is a term that is proposed by Vygotsky. Zone of proximal distance and the concept of Scaffolding are a similar method that is used in teaching methods.

This is the method through which a student gets more information more rapidly than a traditional method. This method is beneficial only when you implement it accurately. On the other hand, if it is not used correctly, it hinders the ability of a student.  

Thus Mr. Reese used the scaffolding method in his teaching. He monitored students' progress, stopping to ask prompting questions and drop the hints to help the students.
