The Effect of Implimentation of TBLT in Reading Comprehension Classes of Iranian EFL Learners

The present study investigates the impact of Task-Based Language Teaching (TBLT) on Iranian EFL learners’ reading comprehension performance. Seventy participants were assigned randomly to the experimental and control groups. Having instructed the two groups with the same texts but different task types and activities (i.e. tasks in 4 types) during 20 sessions, the learners’ reading performance results were compared through utilizing a reading post–test to both groups. The obtained data was analyzed using t-test to examine the effects of independent variable, namely, the method of teaching reading (task-based activities vs. classical reading comprehension) on learners’ reading performance as the dependent variable. As well, the performance of the experimental group in four task types was analyzed in order to investigate possible differences among four reading sets of scores obtained on four task types. A follow up TUKEY test was also conducted to locate the exact areas of difference. Results showed that TBLT had a significantly more positive effect on learners’ reading performance compared to the traditional reading instruction. Also, the second task type investigated in this study, namely reading, taking notes and discussing, was found to be more effective in increasing learners’ reading skill. This study could have pedagogical implications for Iranian teachers and learners, because reading comprehension is a really important part of most instruction and examination systems in Iran.


Task based Language Teaching
The ever-increasing importance of tasks and the prominent role they play in facilitating second language learning have been taken into consideration in recent task-based language teaching (TBLT) studies (Ellis, 2003;Foster, 2009;Samuda & Bygate, 2008;Van den Branden, Bygate, & Norris, 2009;D. Willis & J. Willis, 2007).Task based instruction stems directly from communicative language teaching focusing on meaningful language use and is largely socio-constructivist in nature ( Van den Branden, 2006).
Also there has been a great deal of research on the implementation of tasks in language teaching, particularly tasks which involve interaction between learners (e.g., Breen, 1987;Nunan, 1989;Prabhu, 1987).In second language acquisition(SLA)research, tasks have been widely used as vehicles to elicit language production, interaction, negotiation of meaning, processing of input and focus on form, all of which are believed to foster second language acquisition.Far less empirical research has been carried out where tasks have been used as the basic units for the organization of educational activities in intact language classrooms (van den Branden, 2006).Prabhu (1987) designed task-based teaching and learning tasks based on the concept that effective learning occurs when students are fully engaged in a language task, rather than just learning about language.Willis (1996) defined task as a goal-oriented activity which can have a clear purpose and which involves achieving an outcome through creating a final product that might be appreciated by others.Samuda and Bygate (2008) define task as 'a holistic activity which engages language use in order to achieve some non-linguistic outcome while meeting a linguistic challenge, with the overall aim of promoting language learning, through process or product or both.
with the overall purpose of facilitating language learning.He saw all materials for language teaching as compendia of tasks.Such Task-based Language Teaching (TBLT) is seen to enhance language acquisition by providing learners with the chance of receiving more comprehensible input, furnishing contexts in which learners need to produce output which others can understand, and finally, simulating classrooms to a real life context.

Task based Language Teaching in Action
Regarding the varying claims of TBLT related to classroom practice, recent studies consider three recurrent features: TBLT is in accordance with a learner-oriented education (Ellis, 2003;Richards & Rodgers, 2001); it has particular components such as goal, procedure, a specific outcome (Skehan, 1998), and it focuses on meaning driven activities rather than form focused ones (Breen, 1987).Given the fact that language acquisition is influenced by the complex interactions of a number of variables including materials, activities, and evaluative feedback, TBLT seems to have a dramatic positive impact on these variables (Ellis, 2003).This means that TBLT can provide learners with natural sources of meaningful materials which in turn create ideal situations for real-life communicative activities.Specifically, in EFL (English as a Foreign Language) environments where learners are constrained on their accessibility to use the target language in daily communication, it is needed for language learners to be given real opportunities to be in touch with language use in the classroom (Rashtchi & Keyvanfar, 2007).
TBLT can also make up for the shortcomings of Communicative Language Teaching (CLT) and is viewed as its alternative by many researchers (Klapper, 2003).Usual L2 curricula, including CLT, consider language to be composed of lexis, structures, notions or functions, which are then selected and sequenced for students to learn in a united and incremental way.In this so called 'synthetic' syllabus (Wilkins, 1976), exposures to the target language is intentionally limited and rationed, and the separate parts of the syllabus are gradually built on each other in the belief that this can lead the learner towards the mastery of L2.TBLT declines this type of syllabus, and makes benefit of process-oriented syllabi, in which communicative tasks are designed to improve learners' actual language use.Branden (2011) also explains that Task Based Language Teaching requires learners to be active and have the main roles in learning English language.They have to play important roles and responsibilities in terms of material content, language patterns and expressions during the accomplishment of tasks.They also have representative roles to discuss application aspects and the evaluation of task based language teaching.In this case, the teacher main role is to motivate and to support their students naturally in the process of task based implementation.Skehan (1998) has probed the possibility that tasks may be selected and implemented so that particular pedagogic outcomes are gained.It can be said that any pre-designed task will be changed by the way the learner interacts with it.As a result, the outcome may not be consistent with the objectives intended by the task designer, who may be also the course book writer or the teacher.Similarly, Breen (1987) distinguishes between 'task-as-work plan' and the actual 'task in process and suggests that the two may diverge.Kumaravadivelu (1991) argues that in the context of task-based language teaching, learning outcome is the result of a fairly unpredictable interaction between the learner, the task, and the task context.Thus, being successful in task-based teaching depends largely on the extent to which teacher's intention and learners' interpretations of a given task converge.Building on these insights from SLA and form-focused approaches, TBLT aims to ensure that learners are given plentiful opportunities for two things: (1) receiving meaningful input, or exposure to L2, and (2) having output or experiencing language use.The former is elaborated on by Krashen (1987) under comprehensible input while the latter is called by Swain (1985, cited in Ellis, 2003) as 'pushed output', which enables learners to pick up or acquire those skills and elements of language they are developmentally ready for.

Task based Language Teaching and Reading Instruction
In recent years, a growing interest in the application of TBLT in different realms of second and foreign language teaching has been observed.Among different tasks, the reading-based ones as more integral tasks seem to be more promising since they can involve EFL learners perhaps at the most basic yet essential activity of their academic life.Reading comprehension is a cognitive activity, almost the miraculous one, and like other skills it is a long learning process.Teaching reading is a considerably complex matter.Like other skills, reading is also considered to have different levels.The following features seem to be closely related to the areas which need to be considered in a reading task:

Reading Comprehension
For most people around the globe, reading is by far the most important language skill.Reading is not an inherently natural process in the same way that speaking and listening are in a first language (L1) (Alderson, 2000).If a person is not taught to read, in one way or another (e.g., by a teacher, a parent, a sibling), that person will not learn to read (Grabe & Stoller, 2002).The superabundance of different text-book materials and other reading sources like magazines, journals, newspapers, etc., and the amount of time devoted to going through all these written sources of information denote the fact; the other three language skills can be fostered by the positive access to future educational opportunities and academic settings.Researchers have defined reading comprehension as the process of simultaneously extracting and constructing meaning through interaction and involvement with written language (Doff, 1998).They use the terms "extracting and constructing meaning" to emphasize both the importance and the insufficiency of the text as a determinant of reading comprehension.Reading instruction needs to take into account different types of learners and their needs.Research has shown that there is a great deal of transfer from learning to read in one language to learning to read in a second language (Grabe, 2004).
Despite the great need for reading, this skill is not often fully acquired during school time and even during later educational stages.Learning to read is a type of problem solving, and has often been ignored (Pressley et al, 1992).As a matter of fact, most students fail to comprehend the foreign language texts for their failure in acquiring the reading skill.They seem to read with less understanding than one might expect them to have and slower than they reportedly read in their first language.When we talk about reading and reading instruction, we do so with the basic assumption that reading fundamentally involves comprehending what we read.This idea has been referred to as the finding, or creating, of meaning.The creation of this meaning (the ability to comprehend what we read) depends heavily on having automatic word-level skills and appropriate background knowledge plus a range of comprehension strategies which were mentioned previously.These factors need a lot of attention not only in academic settings but also in early stages of students' acquiring the reading skill (Pressley, 2000).From the view point of both language learning and communicating in real language situations, reading comprehension occupies a position of pre-requisite importance (Cook, 1991).
Text comprehension is one of the main challenges of cognitive science.Comprehension is viewed, according to Nicholson (1998), as constituting understanding and being aware of the communicative purpose and environment that is existent in a text.Comprehension of information is not a goal in its own right, but as a way into fuller command of the language in use (Cook, 1991).Comprehending a language is now recognized to be a creative, complex and active skill involving many processes that have become the focus of classroom orientation as well as psychological studies (I.Taylor & M. M. Taylor, 1990).Haberlandt and Bringham (1990) note that the importance of comprehension in the process of second language learning or acquisition is accepted in almost all the present theories of the profession.They maintain that comprehension is a mutual interaction of textual aspects and the reader's knowledge in which both textual features and reader knowledge work hand in hand at various levels of abstractness.
Text comprehension is a complex cognitive skill in which the reader should construct meaning by using all the available resources from both the text and background knowledge.Additional studies reviewed in Alderson (2000) present conflicting evidence on the role of background knowledge on reading comprehension.Nonetheless, background knowledge appears to provide strong support for comprehension in many contexts.Also type of Genre of the written texts has its own benefits and set of governing rules and conventions which lead to better comprehension (Brown, 2001) The genre of the text helps the readers to apply their schemata which will assist them in extracting appropriate meaning (Brown, 2001).These resources assist readers in utilizing lexis and syntax, retrieving their meaning from one's mental lexicon, making inferences (Alderson, 2000).Allen, Hendler, Tate (1990) note that comprehension is a process by which new or incoming information is related to the information that is already stored in memory.Cook (1991) maintains that comprehension wholly depends on the storing and processing of information by our minds, therefore, comprehension is something mentalistic.In simpler terms, Richard and Rodgers (2001) point out that comprehension is the process by which a person understands the meaning of written or spoken language.

Teaching Reading in TBLT Framework
During the last decades, there have been a plethora of studies and reports on reading purposefully.In one study, Astika (2004) states that keeping engaged in the process of reading in an interactive fashion is effective in providing the students with the skill to tackle the reading problems encountered during their EAP courses.Development of ESP in Iran can best be considered in terms of various EAP programs for all academic fields at university.Ataei (2000) conducted a large-scale study considering the effectiveness of the programs as implemented in the target settings or even the theoretical issues concerning ESP instruction.In relation to reading ability and reading skills, he acknowledged the need for getting EAP readers involved in extensive reading as a highly recurrent criterion task in college-courses (Carrell & Carson, 1997as cited in Ataei 2000, p. 125).
In the most relevant study conducted by Hokmi (2005), the effects of teaching reading comprehension in ESP courses within the framework of task-based language teaching (TBLT) were investigated.The results of this study suggest that reading for message has a positive effect on students reading ability.
Continuing the studies on the effectiveness of reading skills, Tahririan and Basiri (2005) worked on the effectiveness of reading abilities in Internet reading.The results of the study further indicated that reading skills, such as skimming and scanning, are fundamental to Internet reading.The Internet readers mainly favored quick glances from top to bottom of the page.Their eyes moved from one item to the other in search of relevant information.They did not read every word or every line of the page.Hokmi (2005) on his relevant study concluded that "assigning students real-world tasks conveys the value of reading for message and influences the reading comprehension positively".In other words, if students are involved in the process of learning, they will find something that will be advantageous for later use and, consequently, better comprehension takes place.Griva (2003) puts forward reasons in order to maintain that a majority of the proficient readers in an academic context "appreciate the need to orientate themselves to the specific requirements of a reading, and that they need to participate interactively in the process of reading."Moreover, Spector et al. (2001) mentioned that "the nature of the tasks should be directly related to reading materials selected, so that the classroom experience can be utilized by the learner as a springboard for further tasks."D. Willis and J. Willis (2007) support the previous arguments, asserting that "one of the prominent features of the task is involvement in real language use, in which there is an immediate problem to solve" and that this kind of language use reflects the type of language that learners would need in their real-world situation (p.160).
Contrary to the above-mentioned findings, Widdowson (2003) declares that real-world activities will not guarantee any effective contribution to the process of learning for "it is possible for learners to get their messages across" even if the language that is used is minimal (p.125).On the other hand, Ellis (2003, p. 9) referred to some critical features of tasks such as a primary focus on meaning, cognitive engagement and clearly defined communicative outcomes as the features which guarantee, to some extent, students' success in second/foreign language learning.
Reading purposefully is more interesting and text information is understood and recalled better when reading is purpose driven.But how narrowly should the concept of purpose be defined?Evans and Green (2007) conducted a large-scale multifaceted investigation and showed that students find the processing of information at the micro-level (skimming, scanning) more demanding than that carried out at the macro-level (listening, speaking).They also mentioned that reading is a skill that comes from experience and needs to be continuously improved through different types of materials but that efficient reading involves many skills that need to be fostered in a classroom whether in an academic or non-academic context.
A great deal of research has been done in the area of TBLT and reading comprehension.Many researchers have investigated the effect of TBLT on different language skills including reading comprehension, however, the results do not agree in all cases.The present study is an attempt to investigate the effects of different TBLT tasks on reading comprehension of intermediate Iranian EFL learners and aims to answer the following questions: Q1: Does implementing TBLT in reading classes have any significant effect on intermediate Iranian EFL learners' performance?Q2: Which task type has more significant effect on intermediate Iranian EFL learners' performance?

Participants
The population from which this study drew its sample was advanced students studying at different language institutes in Isfahan.To draw the sample, the placement test was administered to 428 advanced level students studying in 6 different language institutes.Based on the results of the OPT test and for the sake of homogeneity, 70 students were considered as the sample of the study.Based on the rating scale of the placement test those who scored between 25 and 40 were considered as intermediate learners.Accordingly, all the participants of the present study scored from 35 to 38.The sample includes both male and female participants, but the number of the latter is bigger (60%).

Instructional Materials
Four tasks were designed based on the students' book in a way that motivated them to follow the text eagerly and enabled them to guess the answers from the text easily.In other words, the texts were available in the students' books and the researchers just had to design the tasks based on the text that was going to be taught during the term.It should be mentioned that the texts were the same for both groups, and just the kind of activities that were based on the texts differed.All told, four task types were used in this study.Following is a brief description of what happened during each task:

Testing Materials
There are two main instruments utilized in this study: 1).A test of the teacher's book of Passages series book 2 was administered to both groups of this study as the reading pre-test.It contained a series of texts which were based on students' pre-learned vocabularies during the semester.At the end, there were some meaning based questions.In other words, the students were not able to answer the questions unless they understood the meaning of the texts.The questions were in different formats.At the end of the study, a similar test was used as reading post test to measure the participants' progress.
2).A second form of instrument was used in the experimental group to evaluate how they performed in four task types.In so doing, the researchers recorded and scored the performance of participants in each task of each task type, and thus were able to come up with an average performance on each task type for each and every individual in the experimental group.

Procedure
After randomly assigning the two groups to the experimental and control one, the treatment started and lasted for forty hours of teaching (20 sessions each lasting for two hours).If we divide the whole period of instruction, i.e. 20 sessions, into 20 two-hour parts, then it can be said that in the control group, students worked on some short conversations, a grammar lesson, and some new vocabularies in the first part of each session.In the second part, they read a text and answered some comprehension questions of open-ended, true/false and/or matching types.
In the experimental group, new vocabularies were taught to the learners during the first part of each session.Then, a simple grammar was taught and different examples were written on the board.In making sentences, they were asked to use the new vocabularies.In the second part of each session, the task papers were brought to the class.Half an hour of the second part of each session was used for reviewing the new words of the previous session and answering the questions.Then, the topic was introduced to the learners and they were given clear instructions on what they had to do to perform the task.In addition, the teacher helped the students recall some language that could be useful for the task.Also, the pre-task stage often included performing a similar task to give students a clear model of what was expected of them.The rest of the time was used for doing the task.The students completed the task individually or in pairs using the language resources available for them while the researcher was monitoring and offering encouragement.
It is worth mentioning that in all the stages of performing the research, the researchers tried to keep the time in both classes the same.After doing the tasks and at the planning stage, the students were asked to prepare a short oral or written report to tell the class what had happened during their task, or simply put, what they had done.Then, they practiced what they were going to say in class.Meanwhile, the instructor was available for the students to ask questions to clear up any language problems they might have had.After the students accomplished each task, the instructor evaluated their work based on a general guideline he had prepared before and scored their performance.The scores obtained on each task type were to be used in the second phase of the study to investigate the possible impact of task type on the participants' reading performance.Furthermore, the students in the experimental group were unaware of this implicit evaluation, and were given only some general feedback and guidelines for the betterment of their work.
After the final session of the instruction, a reading post-test was given to the learners and the scores of both groups were compared with those of pre-test to see if the groups performed differently.

Results
Since the present study mainly focused on comparing reading performance of the experimental and control group before and after the treatment, the main statistical procedure used in the study was a series of t-tests which compared the averages of the two groups in the reading pre-test and post-test.The second part of the research, which was concerned with the performance of the experimental group in four task types, required the calculation of ANOVA to investigate possible differences among four reading sets of scores obtained for four task types.A follow up TUKEY test was also conducted to locate the exact areas of difference.
Phase I: estimated reliability index for the pre-test and post-test was 0.756.Table 1 shows the descriptive statistics and the t-test results of the two groups' reading post-test, respectively.T-test results make it clear that experimental group got higher mean scores than the control group, which indicates a statistically significant difference between the two groups.It implies that using TBLT is superior to the traditional method in reading classes.
Phase II: as it was mentioned earlier, in this project, four types of tasks were used for the treatment of the experimental group.Each session, after doing the tasks, the students' performance was scored.The scores were recorded to be used for a later comparison of task types.In other words, the researchers aimed to use these scores to see in which task(s) the students had done better.It was mentioned earlier that there were twenty tasks in four types, which were given to the students in forty sessions (one task in every session).The average score in each task type was estimated for each student.To investigate in which task type they showed a better reading performance, the students' scores on four types of tasks were compared through ANOVA.Table 2 shows the ANOVA results of four sets of scores.This means that task type 2 had the highest impact on reading performance of the experimental group.Next is task type 3. Task types 1 and 4 had almost equal impacts on student's performance.
To recap, it can be said that a statistically significant difference was found between the reading performances of the experimental group and the control group when comparing their mean scores on reading post-test.That is, the treatment (the application of task-based reading activities) significantly affected the dependent variable (L2 reading comprehension) in Iranian advanced EFL learners.Also, the results of ANOVA and follow-up TTUKEY tests indicated that the students were more successful in the task type of Creative Product.

Discussion
In applying the TBLT instruction, Ellis (2003) maintains that learning takes place when learners are exposed to the language which not only leads to gaining input through naturalistic language, but it also feeds into noticing the gaps in the input and, consequently, filling these gaps.Cases in point were the subjects under TBLT instruction who not only were exposed to language, but also acquired elements of language that learners were developmentally ready for.Forming hypotheses and making learners aware of language forms have been endeavors made to make L2 learning similar to L1 acquisition process.TBLT considers tasks as a necessary and sufficient incentive for language development and close enough to some aspects of the first language acquisition which makes it appropriate for foreign or second language learning context (Ellis, 2003).
According to Richard and Rodgers (2001, p. 223) TBLT displays itself on the use of tasks as the main part of planning and instruction in language teaching, in which learners are basically presented with a task or problem to solve.Chalak, A. (2015) finds out that "the students who were treated by TBLT achieved better reading comprehension than those who were treated by conventional method; secondly, there was an interactional effect between TBLT and grammar mastery upon the students' reading comprehension; thirdly, the students with high grammar mastery gained higher reading comprehension score when they were treated by TBLT than by conventional method; and fourthly, there was significant difference in reading comprehension between the students who had low grammar mastery taught by using TBLT and those who were taught by conventional method".
The corollary of this research documents TBLT as an efficacious, practical and innovative teaching method, at least in teaching the reading to EFL learners at intermediate levels.This research embodied steps such as 'ready to go' (warming-up), reading, and doing some real life tasks.To keep abreast of what's been through during the application of TBLT, students relished the task-based texts as well as welcoming it; their involvement in class activities as well as communicative abilities and skills soared considerably owing to the fact that they hankered after the topics, and finally their propensity to take part in English conversations has set a seal on it.In this research, Task-based reading activities provided the learners with the chance of observing their own progress.
The findings and analyses above substantiate task-based learning to be quite applicable and cornucopian with intermediate learners.The research findings may also contribute to the idea that TBLT may easily prevail in countries in which the evaluation system is quite traditional, and the exams are knowledge-oriented.
To round out, TBLT is considered to be a more effective way for teaching reading comprehension to intermediate learners.Teachers provide their students with a better learning context through implementing tasks in their lesson plans.Last and foremost, TBLT seems to make it a lot easier for teachers to manipulate the factors facilitating the reading comprehension.It can also accentuate the language input to which learners are exposed and give the teachers a chance to provide learners with the required language to do the tasks.

Implications and Conclusion
Those participants of the study who were under task-based instruction outperformed those under traditional methods of reading instruction.Also, the second task, namely read, note and discuss, provided learners with the opportunity to score higher in post-test.Based on the results of the study, it is suggested that utilizing some pre-planned tasks for reading instruction instead of traditional post reading activities such as comprehension questions, true/false and open-ended ones could provide more competent learners.TBLT can have a particularly high value in ELT for Iranian intermediate learners since it demands learners to deal with real life tasks.There seems to be a trend among EFL/ESL practitioners to bring real opportunities to their classroom environments, among which TBLT has much to say.Although the role of tasks in language teaching has been emphasized during last decades, much of this focus has been placed on pedagogical rather than real life tasks.The new century is an opportunity to for a better grasp of the potentiality for the tasks due to the fact that, with the progress in psychology, people have now realized that education can no longer be based on methods designed to produce walking encyclopedias, but rather should promote learning in the broader sense, by starting out from various forms of contact with the concrete and proceeding to its abstract and intellectual representation.The aim of modern teaching is consequently to make teaching adapted to the learners, instead of adapting the learners to its own ends.
All tasks and materials should be utilized with the proviso that they are a source of initiative of teachers seeking to devise methods and a language of learning that, after all, will come most naturally to the learners.From the teacher's point of view, the only criterion affecting their choice of tasks and equipment should be their educational potential and their capacity to convey an accessible image of the multiple and complex reality to be taught to learners.Teachers must not lose sight of the fact that it is partly or entirely through tasks, coupled with a learner's particular perception of the world around them and their behavior upon it that a developing personality emerges and asserts itself, and that world is made up of both their experience and their hopes.

Task 1 :
