This document discusses strategies for teaching language construction and grammar. It outlines four approaches:
1) Studying structure and use, which focuses on language forms, meanings, and functions.
2) Explain and practice, taking a deductive approach by first explaining rules and then having students practice.
3) Discovery and practice, using an inductive approach where students discover language patterns on their own.
4) Research and practice, where students research language independently using resources like dictionaries.
The document also provides specific techniques for each approach, such as choosing study activities, introducing grammar deductively or inductively, and using games to practice grammar.
