THE ACQUISITION LEARNING HYPOTHESIS

The Acquisition-Learning distinction is the most fundamental of all the hypotheses in Krashen's theory and the most widely known among linguists and language practitioners. According to Krashen there are two independent systems of second language performance: 'the acquired system' and 'the learned system'. The 'acquired system' or 'acquisition' is the product of a subconscious process very similar to the process children undergo when they acquire their first language. It requires meaningful interaction in the target language - natural communication - in which speakers are concentrated not in the form of their utterances, but in the communicative act.

The "learned system" or "learning" is the product of formal instruction and it comprises a conscious process which results in conscious knowledge 'about' the language, for example knowledge of grammar rules. According to Krashen 'learning' is less important than 'acquisition'. (See here our in-depth analysis of the Acquisition/Learning hypothesis and its implications).

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.

BEHAVIORISM

This comes from Pavlov and Skinner at the first they use the animals especially dog. Learning is about habit formations which are stimulus and response. So in order someone to learn needs repetition. Repetition is very important in order to understand the speech Language speaking is part of behaviorism of human technically called verbal behavior. KEY ISSUES OF BEHAVIOURISM Social environment is very important in language learning Teachers play central roles in languages Error must be corrected immediately Repetition is is very essential and effective in learning

FIVE LANGUAGE LEARNING THEORIES

1.Behaviourism Theory

2. Mentalism Theory

3. Monitors Theory.

4. Cognitivism Theory.

5. Socio-cultural Theory.
