Question

Alberto is learning algebra. His teacher provides him with classroom instruction and exercises to work at home and also solves problems with the class. When concepts are new, the teacher interacts often with Alberto and his classmates, showing them how to perform operations, giving subtle hints, asking leading questions, and making suggestions. As Alberto becomes more competent in his new skills, his teacher begins to back off, allowing him to work with increasing independence. Alberto's teacher has used the constructivist principle of a. negotiated meaning. b. scaffolding. c. multiple perspectives. d. situated learning.

Answer 1

I believe the answer is: Scaffolding

In education, scaffolding refers to the process when the educators teach their students by providing a simple model that can be used by the students.

The teacher later on, will use that model to slowly guide the student to understand how to solve a more complex problems before eventually back off and let the student solve the problem by his/her own.

This principle is what's used by alberto's teacher when teaching him Algebra.
