Input Hypothesis

Teachers that acquire language methods for teaching a second language are in an advantage of turning academic matter into comprehensible input.

If the input is too far beyond a person's current competence, it becomes incomprehensible noise, and again no acquisition can take place.

Output can lead to comprehensible input needed for acquisition

Krashen claims that people acquire language in only one way

Comprehensible input is the key to language acquisition

Comprehensible input is the source of all acquired language

In order for acquisition to take place learners must receive input that is slightly beyond their current ability level.

The teachers job is to find ways to make academic content comprehensible

Only input leads to acquisition

Output can help people learn academic content
