Methods in ESL. Topic 2. Second Language Acquisition Instructor PPT Video

Alison delivered a comprehensive presentation on second language acquisition (SLA) as the foundation for TESOL certificate training. She explained the critical distinction between language acquisition and learning, emphasizing that acquisition involves creating an implicit linguistic system unconsciously, while learning focuses on explicit, conscious knowledge of grammar rules and discrete skills. The presentation covered major SLA theories including behaviorism, nativism, and interactionist theory, with particular emphasis on Stephen Krashen's five hypotheses about comprehensible input, the affective filter, monitoring, natural order of acquisition, and the importance of allowing learners to use their developing interlanguage without immediate correction. Alison stressed that native-like competence is not an attainable goal for most learners, and instead focused on helping students communicate effectively in various contexts through meaningful, authentic interactions that provide appropriate challenge without overwhelming stress. This is essential content for all TESOL educators.
