The Impact of Form-Focused-Instruction (FFI) and the implementation of Sociocultural Theory (SCT) in Pedagogical Settings on Second Language Learners’ Written Accuracy Following the Innovated Writing Process IWP

The current study argues that learning occurs when there is Ex-implicit grammar teaching and student-student, student-teacher and teacher-student interaction. Following FormFocused-Instruction (FFI) and the implementation of Sociocultural Theory (SCT) in pedagogical settings form the role of the instructor who seeks to improve the Second/Foreign Language Learners’ written accuracy. An empirical study which lasted four months was conducted on 74 Arab Learners of English (ALEs) forming two groups of 37 each. A detailed analysis was made of the target-like and the non-target-like forms of the simple past tense in 222 written texts produced by ALEs. Written texts were collected from each subject at three stages in the experiment (after two weeks, after two months and after four months). Quantitative and qualitative analyses show the positive impact of Form-Focused-Instruction (FFI) and the implementation of Sociocultural Theory (SCT) in pedagogical settings on Foreign Language Learners’ written accuracy following the Innovated Writing Process IWP.


Introduction
One of the SLA theories on which the IWP is based is the Interactionist view, having in consideration that the IWP aims to facilitate the learning process by activating L2 learners' internal processes such as attention, noticing, and rehearsal, which, in turn, make the acquisition of the target linguistic data -simple past tense forms, for example -possible.To clarify the relationship between the IWP and Sociocultural Theory, Lantolf and Thorne (2006, p. 197) mentioned that "SCT has its origins in the writings of the Russian psychologist L.S. Vygotsky and his colleagues".They add that the most important forms of human cognitive activity develop through interaction.With regard to SLA, Sociocultural Theory believes learning is dialogically based which means that the acquisition of the language occurs in the process of interaction rather than as a result of the interaction.Based on this perspective, SLA cannot be treated as a purely individual-based process, but rather as one shared between the individual and other persons (teacher/learners and learners/learners).
In designing the IWP, the dialogic interaction between learners themselves and the teacher is basic in performing the writing task.Having that space for interaction can create a context in which

Form-Focused Instruction
The IWP was designed as a program for teaching writing, and was implemented in the Experimental Group, to investigate the impact of Revising and Redrafting on improving ALEs' written accuracy.The IWP focuses on the role of both the teacher and the learner and gives detailed guidelines for instructors to follow.In designing the IWP, a variety of teaching methods were integrated bearing in mind the L2 learners' level and the types of error/mistake which emerge as they prepare their written work (Mourssi, 2013b).Corrective feedback is provided to the learners by analyzing their errors/mistakes and explaining the nature of the errors/mistakes produced during writing.This will be presented in the discussion which deals with analyzing non-target-like simple past forms and how L2 learners in the Experimental Group managed to produce the target-like forms themselves after receiving metalinguistic feedback.One clear aspect of the course is, then, form-focused instruction (FFI).Norris and Ortega (2001), in Fotos and Nassaji (2007, p. 11) postulated that FFI produces substantial gains in terms of the acquisition of the target structure.Over the course of their study, the effects of FFI were observed to have been sustained over time and the study showed that explicit instructional techniques yielded more positive effects than those involving implicit techniques.Thus, the effectiveness of the instructional treatments depends on the methodological approaches adopted.In evaluating the tasks achieved following FFI, Fotos and Ellis (1991), Fotos (1993), and Leow (2001) noticed that some of the FFI tasks were incorporated more explicitly and that "raising grammar consciousness" is one of these tasks, whereby, the task objective given to learners is to solve a grammar problem using the target structure or to generate grammar rules.That is, the aim behind not giving the target-like forms directly to the L2 learners, but providing them with corrective feedback and allowing them to analyse their errors/mistakes is that it gives them the space to interact, negotiate and work out the rules for themselves which makes them more memorable (Mourssi, 2013c).Both Lyster (2004) and Ferris (2006) suggested that corrective feedback prods the learners to self-correct and that this is effective in promoting SLA.Mourssi (2013d) indicated that the efficacy of analyzing L2 learners' errors/mistakes and giving corrective feedback in language pedagogy varies according to the methods used during the learning process.For example, Audiolingualism thinks that negative "assessment" is to be avoided as far as possible since corrective feedback functions as "punishment" and may inhibit or discourage learning, while Ur (1999, p.243) suggested that "assessment should be positive" in order to promote the positive self-image of the learner as a person and language learner," on the other hand, skilllearning theory thinks that "the learner needs feedback on how well he/she is doing," but the question here is what kind of feedback is the most effective?Is it direct, indirect or metalinguistic feedback?In designing the IWP, all three types were implemented but the last type (metalinguistic feedback) was the basic type followed with the subjects of the study in the Experimental Group.Ur (1999) recognized that there is certainly a space for correcting learners' errors/mistakes, but she claimed that we should not over-estimate this contribution.She concluded that time should be invested in avoiding errors rather than in correcting them.Other methodologists, for example, Harmer (1993) distinguished between "accuracy" and "fluency".He mentions that corrective feedback has a place in the former but not in the latter.However, SLA researchers, especially those working within an Interactionist framework take a different view; they argue that corrective feedback works best when it occurs in context at the time the learners make the error.I can claim that this is one of the main aims behind designing the IWP and presenting the CGLTA through the IWP in the ALEs' context, where the process of error/contrastive analysis (metalinguistic feedback) can develop L2 learners' internalized grammar system which results in promoting L2 grammar acquisition and improving learners' written accuracy (Mourssi, 2013a).Truscott (1996Truscott ( , 1999Truscott ( , and 2007) ) claimed that correcting learners' errors in a written composition may enable the learners to eliminate the errors in a subsequent draft but correcting errors has no effect on grammatical accuracy in a new piece of writing.In other words, correcting errors does not result in acquisition.I think that when the error analysis and the correction of learners' errors are clear, consistent and explicitly presented, it will work well for the acquisition of the target linguistic data (Mourssi, 2012a;2012c).Similar to my claims, Sheen (2007), Ellis, Sheen, Murakami, and Takashima (2009a) produced evidence to show that written feedback can result in Second Language Acquisition; however, I prefer to give the learners oral metalinguistic feedback, as most of them do not seem to read the teacher's written feedback or take it on board.It is worth mentioning that some researchers such as Krashen (1982, p. 74) and VanPatten (1992, p. 24) suggested that correcting errors in learner output has a negligible effect on language learners' developing language system.However, other SLA researchers, especially those working within the Interactionist framework, have found that correcting learners' errors facilitated language acquisition.After more than ten years, VanPatten (2003) changed his mind and acknowledged that feedback (error correction) in the form of negotiating meaning can help learners notice their errors and create form-meaning connections, thus aiding Second Language Acquisition.Recent studies, such as Bitchener, Young, and Cameron (2005), Sheen (2007), and Ellis et al. (2009b) had shown that when corrective feedback is "focused" it is effective in promoting acquisition.
With the Innovated Writing Process IWP, every stage of the development is built after a previous one.In investigating the role of the learner and the role of the teacher for example, there is a link between the reaction of the learner at each stage and the teacher's behaviour and his instructions, from the beginning to the end of the process, in negotiating the mistakes, and giving direct/indirect © Science and Education Centre of North America and metalinguistic feedback.Myles, Hooper, and Mitchell (1998) illustrated that varying strategies in SLA could be built one after another, in the same fashion as with the staged process in the IWP.

A Coalition of Resources
Autonomous Induction Theory (Carroll, 1999;2001) posited that, second language acquisition is facilitated by a coalition of sources that create input to learning.As defined and explained by Herschensohn (2001, p. 26), this theory brings together spontaneous input and form-focused guidance as two complementary components of the learning process.Carroll (1999;2001) argued that the proposed input of learning is not simply processing input but can be considered as a restructuring of interlanguage grammar due to parsing failure on the part of the learner.In other words, Carroll made a distinction between processing for parsing and processing for acquisition.She mentioned that when the parsers fail, the acquisitional mechanisms are triggered, and added that during successful parsing, rules are activated in each processor, and failure occurs when the rules are inadequate or missing.Carroll (1999, p. 365) defined learning in the context of Autonomous Induction Theory as a process which takes place whenever a parse fails (which results from incomprehensible input) and thereby, the process of learning takes place at several levels of analysis such as acoustic-phonetic, phonological, morpho-syntactic and semantic.Similarly, Herschensohn (2000, p. 203) suggested that learners use a coalition of resources such as Universal Grammar, constrained hypothesis space, primary linguistic data, instruction and feedback.This coalition of resources is visible in the IWP.Mourssi (2012b) argued that the interactional process, whether it is negotiated interaction, interactional feedback, noticing gaps in knowledge by learners as well as by the teacher, while speaking or while writing a picture-story, can direct the learners' attention to many things which might have been stored in their memory (implicit knowledge) but that they have temporarily forgotten.The teacher's role is to activate this knowledge which can relate to lexical items, grammatical constructions, phrasal verbs, prepositions, collocations, and so on.Different types of interaction promote development and lead to an actual improvement in learners' knowledge in the long term.Mourssi (2013) indicated that the investigation of the role of revising and redrafting has revealed the positive impact of the IWP and the CGLTA on ALEs undergraduate high school students' writing in general, and their interlanguage grammar in particular, specifically in the acquisition of the simple past tense forms.Weissberg (1998) suggested that classroom writing has positive effects on SLA.Hedge (2005) proposed that students need opportunities to practise various forms and functions in writing.She added in her later study that revising and drafting should be included in improving writing (Hedge, 2005).De La Paz and Steve (2002) suggested that the writing instruction used in middle school classrooms developed a variety of cognitive resources.Kowszyk and Vazquez (2004) noted that peer interaction in groups between the teacher and the students is a very productive strategy in writing and revising written materials.Al-Buainain (2006) believed that there could be no definite answer to the question of how to teach writing in ESL/EFL.Bitchener (2005) and Ferris (2002 and2004) proposed that classroom-based instruction plays a significant role in helping L2 learners improve the accuracy of their writing.Rahimi (2009) noted the effectiveness of feedback on second language learners' writing.The present study contributes to our knowledge in these areas by developing a methodology which integrates Focus-on-Form with revising/redrafting into a communicative approach -the IWP -in order to improve students' written accuracy.

Methods
This section discusses the subjects of the study, the research question and the methods used in the analysis of the written texts.

The Subjects of the Study
Based on the results of a placement test -designed by the researcher-, two similar or nearly similar classes were selected from a total of 12 classes enrolled in grade 12.The two selected classes formed the Experimental Group and the Control Group.Each group -class-consisted of 37 Arab Learners of English (ALEs).The total number of the students involved in the experiment was 74 students, with ages ranging between 16 and 18, pre-intermediate to intermediate level in English.The subjects were all Arabic speakers and had been learning English as a foreign language for eight years attending four to five sessions per week on average.The target location was in one of the Omani government male secondary schools (High School).English language is one of the core subjects that all the students must study in secondary school.

The Research Question
The current study seeks to answer the following question: What are the impact of Form-Focused-Instruction (FFI) and the implementation of Sociocultural Theory (SCT) in pedagogical settings on Second Language Learners' Written Accuracy following the Innovated Writing Process IWP?This is to provide empirical evidence in relation to the acquisition of the Second language structures to test hypotheses emerging from SLA and thus contribute to the advancement of theory on Second Language Acquisition.

Methods Assigned to the Research Question
For the research question presented above, qualitative and quantitative analyses were followed for all the simple past tense forms produced by the samples in 222 written texts which had been collected chronologically.The author thinks in order to explore the impact of Form-Focused-Instruction (FFI) and the implementation of Sociocultural Theory (SCT) in pedagogical settings on Second Language Learners' Written Accuracy following the Innovated Writing Process IWP, three writing texts were collected from each sample in both groups, the first writing text (B) was collected after the first two weeks; the second writing (M) after the first two months while the third writing (F) was collected at the end of the experiment.The author thinks that writing is one way to get evidence of the state of a student's internalized grammar system and to measure the improvement occurs from a certain interlanguage stage to another.

The Instruments Used to Gauge the Impact of FFI and SCT Following the IWP and the CGLTA
The instruments used to gauge the impact of the IWP were as follows; a proficiency test, initial writing test (writing pre-test), pre-interview, and speaking pre-test, picture-story writing one (before the experiment starts) to be sure that the level of both groups is equal or nearly equal, followed by a speaking post-test, writing post-test and finally an achievement test.Scores were compared using statistical tests, such as the t-tests.The Results and Discussion are described in detail below.

Result and Discussion
In this section, the results and the data analysis are presented and explained.Most analysis was based on the quantitative data obtained from all the pre-tests, and post-tests presented in the previous part.The Experimental Group and the Control Group sat exactly the same pre-tests and post-tests to ensure comparability across the groups.It is also necessary to mention that the official Final National Exam (FNE) is run on all the students enrolled in grade 12 all over the Sultanate at the same time, with two invigilators in each class.The FNE is the same exam for all the students, and students must be arranged alphabetically in each school and in groups of 24-26 in different classes.In other words, the Experimental Group students and the Control Group students were not in the same classes or at the same school as they were during the experiment.In the following, I will present the quantitative analysis following the same sequence as that followed in describing the instruments used in the study.

Results of the T-Test for Independent Groups in the Proficiency Test
A t-test was applied in order to ensure that there was not a significant difference in the proficiency scores between the two groups at the outset.The t-test results and the Independent Samples Test are in Appendix P. The result shows that t = 0.97, df = 72, p = > .05.This means that there was no significant difference between the two groups in the proficiency test.The results show that the students in the Control and Experimental Groups were almost at the same level at the beginning of the experiment.

Results of the T-Test for Independent Groups in Speaking Pre-Test
The results from the comparison of the scores of the Control Group and the Experimental Group show that t = 0.97, df = 72, p = > .05.This means that there was no significant difference between the two groups in the speaking pre-test.(See Appendix A)

Results of the T-Test for Independent Groups in Initial Picture-Story Writing
The results of the comparison of the scores of the Control Group and those of the Experimental Group in the initial picture-story writing show that t = .001,df = 72, p = > .05.This means, there was no significant difference between the two groups in the initial writing test (see Appendix A).
After marking the initial picture-story essay and doing the statistical analyses, a picture-story writing exercise was given to both the Experimental and Control Groups before starting the experiment to be sure that the two selected groups were equal or nearly equal from the beginning and before starting the experiment.

Results of Picture-Story Writing One
I was advised to be sure that the two selected groups for the experiment should be equal or nearly equal before running the experiment for the sake of the results at the end.Based on that, it was decided to run an additional picture-story writing namely Picture-Story Writing One.
The results of the comparison of the Control Group and the Experimental Group in picture-story one show that t = 0.52, df = 72, p = > .05.This result means that there was no significant difference between the two groups in the picture-story writing one test (see Appendix A).
After obtaining and analyzing all the results, the two groups were compared statistically.The author thus ensured that the two groups were equal or almost equal in performance.Sakel and Everett (2012, p. 133) recommend that in order for the intervention to be deemed successfully, the Control Group and Experimental Group should be equal or nearly equal in all the pre-tests from the beginning.

The Statistical Analysis for Paired Samples (The Experimental Group's Pre-and Post-Tests)
Note: (The results of the statistics related to the Experimental Group are tabulated in Appendix B).
The result of the t-test for paired samples (the Experimental Group) in the proficiency test and the achievement test shows that t = 15.383,df = 36, p = < .001.The results show that the difference between the proficiency test and the achievement test is significant.The result of the t-test for paired samples (the Experimental Group) in the speaking pre-test and the speaking post-test shows that t = 15.372,df = 36, p = < .001.The results show that the difference between the speaking pretest and speaking post-test is significant.The result of the t-test for paired samples (the Experimental Group) in the writing pre-test and the post post-test shows that: (t = 17.234, df = 36, p = < .001).The results show that the difference between the writing pre-test and writing post-test is significant.
Table 1 presents the correlations of paired samples (the Experimental Group).The results show that the correlation is highly significant.The results of the statistics related to the Control Group are tabulated in Appendix C. The result of the t-test for paired samples (the Control Group) in the proficiency test and the achievement test shows that: (t = 4.905, df = 36, p = < .001).The results show that the difference between the proficiency test and the achievement test is significant.The result of the t-test for paired samples (the Control Group) in the speaking pre-test and the speaking post-test shows that: (t = 6.368, df = 36, p = < .001).The results show that the difference between the speaking pre-test and speaking post-test is significant.
The result of the t-test for paired samples (the Control Group) in the writing pre-test and the post post-test shows that: (t = 13.800,df = 36, p = < .001).The results show that the difference between the writing pre-test and writing post-test is significant.Table 2 presents the correlations of paired samples (the Control Group).The results show that the correlation is significant.

The T-Test for Independent Groups (Experimental and Control)'S Pre-and Post-Tests and the Final National Exam
All the t-tests results related to the pre-tests and post-tests are tabulated in Appendix D. The results of t-test for independent groups in speaking post-test show that: (t = 6.597, df = 72, p = < .001).This means that the difference between the Experimental Group and the Control Group is significant.
The results of t-test for independent groups in writing post-test show that: (t = 5.388, df = 72, p = < .001).This means that the difference between the Experimental Group and the Control Group is significant.
The results of t-test for independent groups in achievement test show that: (t = 4.187, df = 72, p = < .001).This means that the difference between the Experimental Group and the Control Group is significant.
The results of t-test for independent groups in Final National Exam show that: (t = 2.390, df = 72, p = < .001).This means that the difference between the Experimental Group and the Control Group is significant.
The sections 4.1-7 presented in detail the reports of the pre-tests, and the post-tests.The results of the data analysis show no significant differences in all the pre-tests between the two groups, but significant differences can clearly be discovered at the post-tests and the achievement test as well.
The learners' score in the Final National Exam support these results, the scores of the learners in the Experimental Group was higher than the scores of the learners in the Control Group, see Appendices E for more detail.

One-Way ANOVA from Target-Like and Non-Target-Like Simple Past Forms in the Experimental Group by Stage
To support the results and to identify of the impact of revising and redrafting as a part of the IWP and to support the role of CGLTA in improving ALEs' writing, One-way ANOVA was run on the target-like and non-target-like simple past forms in both groups in the three stages, for more details see Appendix I.
The results of One-way ANOVA show that the mean of the target-like simple past forms in stage 1 (AB in the Experimental Group) is 8.0000, and the mean of stage 2 (AM in the Experimental Group) is 9.2703, the mean of stage 3 (AF in the Experimental Group) is 14.2973.The results also show that the value of F for the target-like forms of the simple past tense in the Experimental Group in the in the three stages AB, AM, and AF is 17.833 and it is significant.The following figure shows the means plot of the target-like simple past forms in the Experimental Group (see Figure 1).
The results of One-way ANOVA show that the mean of the non-target-like simple past forms in stage 1 (AB in the Experimental Group) is 6.1892, and the mean of stage 2 (AM in the Experimental Group) is 6.0541, the mean of stage 3 (AF in the Experimental Group) is 1.1622.The results also show that the value of F for the non-target-like forms of the simple past tense in the Experimental Group in the in the three stages AB, AM, and AF is 31.746and it is significant.The following figure shows the means plot of the non-target-like simple past forms in the Experimental Group (see Figure 2).

One-Way ANOVA from Target-Like and Non-Target-Like Simple Past Forms in the Control Group by Stage
The results of One-way ANOVA show that the mean of the target-like simple past forms in stage 1 (BB in the Control Group) is 5.5135, and the mean of stage 2 (BM in the Control Group) is 6.4595, the mean of stage 3 BF in the Control Group) is 9.8649.The results also show that the value of F for the target-like forms of the simple past tense in the Control Group in the in the three stages BB, BM, and BF is 9.759 and it is significant.The following figure shows the means plot of the targetlike simple past forms in the Control Group (see Figure 3).
The results of One-way ANOVA show that the mean of the non-target-like simple past forms in stage 1 (BB in the Control Group) is 9.1892, and the mean of stage 2 (BM in the Control Group) is 7.0541, the mean of stage 3 (BF in the Control Group) is 3.8919.The results also show that the value of F for the non-target-like forms of the simple past tense in the Control Group in the in the three stages BB, BM, and BF is 16.864 and it is significant.The following figure shows the means plot of the non-target-like simple past forms in the Control Group (see Figure 4).To conclude, the data analysis presented show that the IWP and the CGLTA can help the learners improve their writing as well as speaking.The results of the above quantitative data provide some evidence for the improvement occurred in the Experiment Group, though I cannot identify which variable(s) involved in the process of redrafting was/were responsible for the differential improvement of the Experimental Group; these variables included the focus on error/contrastive analysis (metalinguistic feedback), student-student interaction, explicit grammar teaching, negotiation and the personality of the tutor.Similarly, we can say that the IWP and CGLTA appeared to improve performance (by comparison with TPW approach) -but we do not know exactly what it was about them which improved performance and it is thus quite difficult to say anything very precise about Second Language Acquisition theories, though the experiment does provide support for current notions in Applied Linguistics concerning the benefits of a process over a product approach to writing.

The Experimental Group
The results of the t-test of target-like and non-target-like simple past forms in stage AB show that the mean of the target-like forms is 8.The mean of the non-target-like forms is 6.2.The value of t = 1.676, p = .098,and p > .05.These results show that the difference between target-like forms and non-target-like forms in stage AB in the Experimental Group is not significant, for more details see

The T-Test (Independent Sample Test) for Target-Like Simple Past Forms in Stage AF in the Experimental Group and BF in the Control Group
The results of the t-test of target-like simple past forms in stage AF and BF show that the mean of the target-like forms in AF for the Experimental Group is 14.3.The mean of the target-like forms in BF for the Control Group is 9.9.The value of t = 4.9, p = .000,and p < .05.These results show that the difference between target-like forms in AF and BF in the Experimental Group and the Control Group at the end of the experiment after four months is high significant.

The T-Test (Independent Sample Test) for Non-Target-Like Simple Past Forms in Stage AB in the Experimental Group and BB in the Control Group
The results of the t-test of non-target-like simple past forms in stage AB and BB show that the mean of the non-target-like forms in AB for the Experimental Group is 6.2.The mean of the non-targetlike forms in BB for the Control Group is 9.2.The value of t = -3.049,p = 003, and p < .05.These results show that the difference between non-target-like forms in AB and BB in the Experimental Group and the Control Group after the first two weeks in the experiment is significant, for more details see Appendix H.

The T-Test (Independent Sample Test) for Non-Target-Like Simple Past Forms in Stage AM in the Experimental Group and BM in the Control Group
The results of the t-test of non-target-like simple past forms in stage AM and BM show that the mean of the non-target-like forms in AM for the Experimental Group is 6.1.The mean of the nontarget-like forms in BM for the Control Group is 7.1.The value of t = 1.54, p = .252,and p > .05.These results show that the difference between non-target-like forms in AM and BM in the Experimental Group and the Control Group after the first two months in the experiment is not significant.

The T-Test (Independent Sample Test) for Non-Target-Like Simple Past Forms in Stage AF in the Experimental Group and BF in the Control Group
The results of the t-test of non-target-like simple past forms in stage AF and BF show that the mean of the non-target-like forms in AF for the Experimental Group is 1.2.The mean of the non-targetlike forms in BF for the Control Group is 3.9.The value of t = 4.824, p = .000,and p < .05.These results show that the difference between non-target-like forms in AF and BF in the Experimental Group and the Control Group at the end of the experiment after four months is high significant.

Conclusion
The results of the experiment show that, when second language learners receive metalinguistic feedback which enhances their awareness and draws their attention to the non-target-like forms, and when they are given the opportunity to interact, negotiate, and discuss their work with their peers and the teacher, in the revised and redrafted version, they move progressively towards greater accuracy in producing the target-like forms.As a result of following the IWP, the students not only improved their written accuracy in the short term but also developed their internalized grammatical system and improved their level of proficiency in general.This clearly appeared in their scores in the Final National Exam.This improvement was confirmed by quantitative and qualitative analysis in the current study.
It is noticed that students make successive hypotheses about forms and these are discussed in "negotiated interaction" which is based on negotiating the mistakes and creating a space for that to happen, following the process of error/contrastive analyses in which the teacher discusses the errors explaining the nature of the learners' errors/mistakes (metalinguistic feedback).
One conclusion of the current study is that the method devised and implemented -the IWP -helped ALEs at pre-intermediate and intermediate level improve their accuracy in writing and develop their internalized grammatical system.
