This document discusses key concepts in language teaching and language acquisition. It covers 12 topics:
1. Language teaching involves teaching vocabulary, structures, pronunciation, and function. However, languages differ in their rules and conventions.
2. Language acquisition in children is remarkable in that it happens efficiently and without formal instruction, through natural interaction and exposure to language from a young age.
3. Both accuracy and fluency are important goals in language learning, but they require distinguishing between practices that emphasize correct usage versus effective communication. Interesting communicative tasks can increase student motivation.
