Melanie and derek are planning to move to a new home, and are strongly considering different school options for their children. melanie wants her children to be active learners who can think creatively and critically. she also wants a student-centered approach. melanie is looking for

a. constructivist approach. direct instruction approach. scaffolding approach. collegial approach.

The pedagogic current of Constructivism proposes a paradigm where the teaching process is perceived and carried out as a dynamic, the subject participates and interacts actively, so that knowledge is an authentic construction operated by the person who learns (by the "knowing subject") it is applied in teaching as in action-oriented teaching.  

On the other hand, the direct instruction approach is centered in the teacher, though he/she has the responsibility to identify the needs and skills of the alumni and they actively participate in the process, is the docent who leads the process in a structured methodology.  

In the scaffolding approach the process of learning is guided through a process of building knowledge structures in order to reach the potential skills that would not be possible to learn autonomously. In this pedagogic approach, it is considered the proximal zone of development (PDZ) which is the space between the actual abilities of the alumni and those he/she can reach, this model corresponds to the evolutive psychology and in it, the teacher is more facilitator.  

Finally, the collegial approach is the “traditional” method where the teacher rules and the alumni obey and hear.

Therefore, the correct answer is a) Melanie is looking for the constructivism approach for their children.

b) the planets year length would be longer

hope this !
