Techniques range from controlled, with predictable responses, to free, with open-ended communication. Examples of controlled techniques include repetition and dictation, while student-centered discussions exemplify free techniques. The document also examines how technology, including computer-assisted language learning, can support language instruction through practice, feedback and communication opportunities.
