6. What are the two key questions to address when considering enhancing L2 learners' communicative competence?

There are two key questions exercising both teachers and researchers when considering how L2 learners’ communicative competence can best be advanced in the language classroom:

1.                   How do students learn languages?

2.                   How should we teach languages?

When it comes to L2 teaching and learning, language teachers’ reflections on practice and SLA researchers’ empirical investigations aim to identify the processes involved in learning a new language and what appears to have the most beneficial impact in and for the classroom. Several foundational theoretical perspectives on learning help to inform our thinking about effective instruction. (East, 2021)
