Дипломная работа: Ways of teaching foreign languages
The results of the research on comprehension-based ESL also appear to provide support for Krashen's comprehensible input hypothesis. It is important to keep in mind, however, that the learners in the comprehension-based studies are beginner-level learners and it is far too early to know how their second language skills will continue to develop. It is certainly possible (indeed probable) that learners in comprehension-based programs, like the Native language immersion learners, will have considerable gaps in their linguistic knowledge and performance over time. And, like the Native language immersion learners, they too will probably need and benefit from opportunities to use the language interactively as well as from some careful form-focused intervention later in their development.
The TPR results also show great benefits for learners in the early stages of development. Krashen says of TPR that it prepares learners to go out into the target language community to get more comprehensible input which, he says, will carry their language acquisition further.
In summary, comprehension-based programs appear to be beneficial in the development of basic comprehension and communicative performance in the early stages of learning (particularly in situations where learners have no other contact with the target language apart from in classroom situations). But they may not be sufficient in getting learners to continue to develop their second language abilities to advanced levels.
8.2 Teach what is teacheable
The proposal referred to as 'Teach what is teachable' is one which has received increasing attention in second language acquisition research in recent years. The researcher most closely associated with this view is Manfred Pienemann. He and his associates are concerned with being able to explain why it often seems that some things can be taught successfully whereas other things, even after extensive or intensive teaching, seem to remain unac-quired. They claim that their research provides evidence that some linguistic structures, for example, basic sentence word order (both simple and complex) develops along a particular developmental path. Thus, for example, any attempt to teach a word order pattern that is a 'Stage 4' pattern to learners at 'Stage 1' will not work because learners have to pass through 'Stage 2' and get to 'Stage 3' before they are ready to acquire what is at 'Stage 4'. The underlying cause of the stages has not been fully explained, but there has been considerable research showing that they may be based at least in part on learners' developing ability to process (unconsciously analyse and organize) certain elements in the stream of speech they hear.
Researchers supporting this view also claim that certain other aspects of language—vocabulary, some grammatical features—can be taught at any time. A learner's success in learning these variational features will depend on factors such as motivation, intelligence, and the quality of instruction.
While this line of research has the potential to inform classroom teachers about which aspects of language acquisition are 'developmental' (and thus teachable only in a given sequence) and which are Variational' (and thus teachable at various points in learner language development), there is much work to be done before the findings of this research can lead to recommendations about whether particular forms can be taught and when.
In Examples 9 and 10 below, we see a teacher trying to help students with question formation. The students seem to know what they mean, but the level of language the teacher is offering them is beyond their current stage of development. The students react by simply answering the question or accepting the teacher's formulation.
Example 9
(A group of twelve-year-old students, interviewing each other as they play the roles of imaginary people.)
S1What's your nationality?
S2 I am Russian.
S1 What old, um, do you, uh, have—?
T 'How old' dear. 'How old' were you—?
S1 How old do you have... No, never mind.
T How old were you when you came here?
S1 Uh,yeah.
Example 10
(The same group of students, asking fellow students questions about award poster which they had recently received.)
S1 Mavluda, where you put your 'Kid of the Week' poster?
T Where didyou put your poster when you got it?
S2 In my room. (2 minutes later)
S3 Mashhura where you put your 'Kid of the Week' poster?
T Where did you put your poster?
S4 My poster was on my wall and it fell down.
In Example 11 below, the student is using a 'fronting' strategy which is typical of Stage 3 learners. That is, the student simply places an auxiliary verl (in this case 'is') at the beginning of the sentence but does not change the res of the sentence. (Note that if the student had fronted 'does', the sentencl would have been correct, but we would not have been able to see how the student thought question formation worked.) In this case, the teacher's correction leads the student to produce a Stage 4 question. In Example 12, same situation appears. This time, however, the correction leads not to reformulation of the question, but simply to an answer.
Example 11
(Examples 11, 12, 13, and 14 are from a group of twelve-year-old Uzbek speakers learning English as a foreign language.) ('Famous person' interviews)
S1 Is your mother play piano?
T 'Is your mother play piano?' OK. Well, can you say 'Is your mother play piano?' or 'Is your mother a piano player?'
