The results of the adverb study revealed that learners who received instruction on adverb placement dramatically outperformed the learners who did not receive instruction on adverbs. This was found to be the case on all tests in both the immediate and delayed post-tests (immediately following instruction and six weeks later). In the follow-up tests a year later, however, the gains made by the learners who had received the adverb instruction had disappeared and their performance on this structure was like that of uninstructed learners.
The results of the question formation study revealed that the instructed group made significantly greater gains than the uninstructed group on the written tasks immediately following instruction. Furthermore, it was found that the instructed learners maintained their level of knowledge on later testing (six weeks and six months after instruction). It was also found that a focus on form contributed to improvements in oral performance on questions.
Analysis of classroom language showed that adverbs were very, very rare in classroom speech, giving learners little opportunity to maintain their newly acquired knowledge through continued exposure and use. In contrast, there were hundreds of opportunities to hear and use questions every day in the classroom.
10.2 Grammar aquisition: Focusing on past tenses and conditionals
Focusing on past tenses
As mentioned earlier in this chapter, there is a growing belief that learners in native language immersion programs need more opportunities to focus on form and receive corrective feedback. There has been a call for more classroom research of the type exemplified by Studies 16 and 17 to determine how this can best be accomplished.
Birgit Harley See: Harley, B. 1989. 'Functional grammar in native language immersion: A classroom experiment. p.331 (1989) examined the effects of a functional approach to grammar teaching on a particularly problematic area of grammar for English-speaking learners of native language--the contrastive use of two past tense forms for 'My mother often spoke about her child-hood', and roughly the specific or narrative past, for example, 'After class I had talked with the other students'.
Approximately high grade 6 immersion students were given instruction on the use of these past tense forms through teaching materials which encouraged their use in a variety of functionally-based practice activities. No explicit grammatical rules were provided, nor was there an emphasis on corrective feedback. The intention was to create opportunities, activities, and tasks which would expose them to more input containing both verb forms, and encourage more productive use of them by the learners. The teaching materials were administered over an eight-week period. Learners were tested on their spoken and written knowledge before the instructional treatment began, eight weeks later, and again three months later.
Harley's findings showed that learners in the experimental classes outperformed the control classes on the immediate post-tests on some of the written and oral measures. Three months later, however, there were no significant differences between the two groups.
Focusing on the conditionals
Elaine Day and Stan Shapson See: Day, E. and S. Shapson. 1991. 'Integrating formal and functional approaches to language teaching in Native language immersion: An experimental approach.' Language Learning 41: 25--58. (1991) examined the effects of instruction with average grade 7 students (age about twelve or thirteen). The feature of grammar which was taught was the conditional mood of the verb, for example in sentences such as 'Agar men lotereyada yuib olsam, sayohatga borar edim'. -' If I won the lottery, I would go away on a trip'.
Students in the experimental classes received several hours of focused instruction on the conditional over a period of five to seven weeks. The students in the control group continued with their usual classroom routines, that is, they continued to encounternative language mainly in the context of learning their general school subjects (science, mathematics, history, etc. through the medium of native language).
Special teaching materials were prepared by the team of researchers. They consisted of:
1) group work which created situations for the use of the conditional in natural communicative situations;
2) written and oral exercises to reinforce the use of the conditional in more formal, structured situations;
3) self-evaluation activities to encourage students to develop conscious awareness of their language use.
Oral and written tests were administered before the instructional treatment, immediately after the instruction (five to seven weeks later), and at the end of the school year.
Learners in the experimental classes outperformed those in the control classes on the immediate post-tests for the written tasks (but not for the oral). In contrast to the students in Study 16, they were still doing better than the control group on the follow-up post-tests administered several months later.
Interpreting the research
The overall results of the experimental studies in the intensive ESL and native language immersion programs provide partial support for the hypothesis that enhanced input or form-focused instruction and corrective feedback within communicative second language programs can improve the learners' use of particular grammatical features. The results also show, however, that the effects of instruction are not always long lasting. For example, in the intensive program studies, the positive effects of form-focused instruction on adverb placement had disappeared a year later. Yet, the positive effects of this type of instruction and corrective feedback for questions were maintained in the long-term follow-up testing. Similarly, in the experimental native language immersion studies, while there were only short-term instructional benefits for the use of the imparfaitand passe compose, the benefits of instruction for the use of the conditional continued to be evident several months later.
It would be useful to notice here that the different results of the intensive ESL program findings might be explained in terms of the frequency of use of the two linguistic structures inregular classroom input after the experimental treatment had ended. For example, as mentioned in Study 15, question forms occur much more frequently in classroom input than adverbs. This continued reinforcement may have contributed to the continued improvement in the learners' use of questions over time. Evidence from classroom observations suggests that students did not receive any continued reinforcement through exposure to adverbs in classroom materials and activities once the experimental period was over, and thus it should not be surprising that these learners failed to maintain the improved performance levels.
The contrasting results of the native language immersion program teaching experiments (focuses on grammar) may also be explained by potential differences in input. But in this case, it seems more likely that differences in the experimental teaching materials and methodology may have contributed to the different results. Although both sets of materials had as their goal to provide learners with the opportunity to use the linguistic forms in a variety of functionally-based communicative practice activities, the instructional materials for the 'past tense' study (past tenses) may not have been sufficiently form-focused or did not draw the learners' attention to their language use as frequently and as explicitly as the instructional materials for the 'conditional' study (conditionals). While this is a possible explanation, other factors may have contributed to the different outcomes. For example, it could be that the two linguistic structures under investigation respond to instruction in different ways or that even the relatively small differences in the age of the learners played a role.
11.2 The implications of classroom research for teaching
It is difficult to draw firm conclusions about the strength of the theoretical proposals until further research is completed. But it is possible to speculate on the 'strongest contenders' on the basis of the classroom research findings so far This chapter we based on the internet materials the address of which is mentioned in the bibliography list.
There is increasing evidence that learners continue to have difficulty with basic structures of the language in programs which offer no form-focused instruction. This calls into question the 'Just listen' proposal, which in its strongest form not only claims no benefit from form-focused instruction and correction, but suggests that it can actually interfere with second language development. However, we do not find support for the argument that if second language learners are simply exposed to comprehensible input, language acquisition will take care of itself.
There are similar problems with the 'Say what you mean and mean what you say' proposal. As noted earlier in this chapter, there is evidence that opportunities for learners to engage in conversational interactions in group and paired activities can lead to increased fluency and the ability to manage conversations more effectively in a second language. However, the research also shows that learners in programs based on the 'Say what you mean and mean what you say' proposal continue to have difficulty with accuracy as well.
Because these programs emphasize meaning and attempt to simulate 'natural' communication in conversational interaction, the students' focus is naturally on what they say, not how to say it. This can result in a situation where learners provide each other with input which is often incorrect and incomplete. Furthermore, even when attempts are made to draw the learners' attention to form and accuracy in such contexts (either by the teacher or other learners), these attempted corrections may be interpreted by the learners as continuations of the conversation. Thus, programs based on the 'Just listen' and 'Say what you mean and mean what you say' proposals are incomplete in that learners' gains in fluency and conversational skills may not be matched by their development of accuracy.
It is important to emphasize that the evidence to support a role for form-focused instruction and corrective feedback does not provide support for the 'Get it right from the beginning' proposal. Research has demonstrated that learners do benefit considerably from instruction which is meaning-based. The results of the native language immersion and intensive ESL program research are strong indicators that many learners develop higher levels of fluency through exclusively or primarily meaning-based instruction than through rigidly grammar-based instruction. The problem remains, however, that certain aspects of the linguistic knowledge and performance of second language learners are not fully developed in such programs.
Unfortunately, research investigating the 'Teach what is teachable' proposal is not yet at a point where it is possible to say to teachers: 'Here is a list of lin-guistic features which you can teach at any time and here is another list which shows the order in which another set of features will be acquired. You should teach them in this order.' The number of features which researchers have investigated with experimental studies within this framework is simply far too small.
Similarly, second language researchers working from the 'Get it right in the end' proposal cannot yet provide a list of those forms which mustbe taught. Nonetheless, because these proposals do not argue for exclusively form-based or meaning-based instruction, but rather acknowledge a role for form-focused instruction and correction within a communicative program, the 'Teach what is teachable' and 'Get it right in the end' proposals appear to be the most promising at the moment in terms of guiding decisions about second language teaching.
3. Conclusion
Classroom data from a number of studies offer support for the view that form-focused instruction and corrective feedback provided within the context of a communicative program are more effective in promoting second language learning than programs which are limited to an exclusive emphasis on accuracy on the one hand or an exclusive emphasis on fluency on the other. Thus, we would argue that second language teachers can (and should) provide guided, form-based instruction and correction in specific circumstances. For example, teachers should not hesitate to correct persistent errors which learners seem not to notice without focused attention. Teachers should be especially aware of errors that the majority of learners in a class are making when they share the same first language background. Nor should they hesitate to point out how a particular structure in a learner's first language differs from the target language. Teachers might also try to become more aware of those structures which they sense are just beginning to emerge in the second language development of their students and provide some guided instruction in the use of these forms at precisely that moment to see if any gains are made. It may be useful to encourage learners to take part in the process by creating activities which draw the learners' attention to forms they use in communicative practice, by developing contexts in which they can provide each other with feedback and by encouraging them to ask questions about language forms.
Decisions about when and how to provide form focus must take into account differences in learner characteristics, of course. Quite different approaches would be appropriate for, say, a trained linguist learning a fourth or fifth language, a young child beginning his or her schooling in a second language environment, an immigrant who cannot read and write his or her own language, and an adolescent learning a foreign language at school.
It could be argued that many teachers are quite aware of the need to balance form-focus and meaning-focus, and that recommendations based on re-search may simply mean that our research has confirmed current classroom practice. Although this may be true to some extent, it is hardly the case that all teachers approach their task with a clear sense of how best to accomplish their goal. It is not always easy to step back from familiar practices and say, 'I wonder if this is really the most effective way to go about this?' Furthermore, many teachers are reluctant to try out classroom practices which go against the prevailing trends among their colleagues or in their educational contexts, and there is no doubt that many teachers still work in environments where there is an emphasis on accuracy which virtually excludes spontaneous lan-guage use in the classroom. At the same time, there is evidence that the intro-duction of communicative language teaching methods has sometimes resulted in a complete rejection of attention to form and error correction in second language teaching.
Teachers and researchers do not face a choice between form-based and meaning-based instruction. Rather, our challenge is to determine which fea-tures of language will respond best to form-focused instruction, and which will be acquired without explicit focus if learners have adequate exposure to the language. In addition, we need to develop a better understanding of how form-based instruction can be most effectively incorporated into a com-municative framework. Continued classroom-centred research in second language teaching and learning should provide us with insights into these and other important issues in second language learning in the classroom.
