Second Language Acquisition Theories

How Do We Learn Languages?

Second Language Acquisition (SLA) explores how people learn languages beyond their mother tongue. Researchers have developed several theories to explain this process.

Major Theories

  • Behaviorist Theory: Language is learned through imitation and practice.
  • Innatist Theory: Humans have an inborn ability (a "language acquisition device") to learn languages.
  • Interactionist Theory: Social interaction is key to language learning.

Classroom Applications

Teachers might use role-plays (interactionist), pattern drills (behaviorist), or encourage natural conversation (innatist).

Why Does It Matter?

Understanding SLA helps educators design effective lessons and helps learners choose the right strategies.

Examples

  • A teacher uses songs and games to make learning fun.

  • A student improves quickly by practicing conversations with friends.
