The document summarizes theories by Lev Vygotsky and John Keller that inform the Scrooge Project. [1] Vygotsky's socio-cultural theory emphasizes social interaction, scaffolding, and the zone of proximal development. [2] Keller's motivation theory focuses on maintaining student motivation through attention, relevance, confidence and satisfaction. The Scrooge Project aims to apply these theories by incorporating group work, feedback, and allowing students to control their own learning.
