The document discusses the psychological bases of the learning process, including Lev Vygotsky's theories of scaffolding and the zone of proximal development. It provides three key points:
1) Vygotsky believed learning is most effective in a social environment, where learners construct meaning through interaction with others. His zone of proximal development refers to what a learner can do with help versus independently.
2) Scaffolding refers to instructional techniques that help move students toward stronger understanding and independence, by controlling elements initially beyond their capabilities. It involves gradually reducing support as learners gain competence.
3) Effective scaffolding includes assessing learners' knowledge, relating new content to existing understanding, breaking tasks into manageable steps
