MONITORS THEORY

This theory come from  the scholar called Stephen Krashen  and he said that human being acquire language without instruction you do not need to say or teach in classroom because of Stephen Krashen  come with five hypothesis
1. The acquisition learning hypothesis.

2. Natural Order Hypothesis.

3. Input Hypothesis.

4. Monitor Hypothesis.

5. Affective Filter.

Clearly, an ESL student cannot cope with or learn from language input that is at i+6 or i+13. The input must be made comprehensible. Indeed, Krashen states that comprehensible input is a sufficient condition for language acquisition. However, Krashen further claims that no language will be acquired in the presence of the affective filter. This simply means that an ESL student who is nervous or bored in class will learn neither subject content nor new language, even if the input is comprehensible.
