According to the theories of Lev Semenovich Vygotsky, and Sociocultural theory, “Students should be put in situations where they have to reach to understand, but where support from other students or the teacher is also available.  Sometimes the best teacher is another student who has just figured out how to solve the problem, because this student is probably operating in the learner’s zone of proximal development.  Students should be guided by explanations, demonstrations, and work with other students-opportunities for cooperative learning”
