This document summarizes a workshop on theories of second language acquisition and their connections to foreign language teaching practices. The workshop goals are to review SLA theories, ACTFL Proficiency Guidelines, Standards for Language Learning, and discuss how these relate to classroom instruction and the role of grammar teaching. Key SLA theories discussed include Chomsky's Universal Grammar, Krashen's Monitor Model, communicative competence, and sociocultural learning theory. Participants reflect on linking theories to practices and challenges in the field.
