Effects of Task-based Language Teaching ( TBLT ) Approach and Language Assessment on Students ’ Competences in Intensive Reading Course

Task-based language teaching on the purpose of enhancing students’ communicative skills and involving them actively in the authentic context has long been highlighted in recent years in tertiary English language teaching. This paper proposes a framework of task-based teaching approach and language assessment in intensive reading class based on the researcher’s own teaching practice to explore positive impacts on students’ competences. This is done in the context of both oral presentation and written reports of first undergraduate English major students. The research method consists of semi-structured interviews and a questionnaire with 18 questions pointing to different aspects in the learning and teaching processes, aiming to explore what impacts it has on students’ competence in both second language acquisition and at cognitive level. In this empirical study, all the findings indicate that TBLT applied in Chinese English teaching class is very effective and beneficial for the enhancement of Chinese English learners.


Introduction
Task-based language teaching (TBLT) and language assessment have gained much attention in recent years.In the language teaching literature, a task can be viewed in several ways.It is structured, used in real world for communication, and usually with outcomes or specific objectives (Crookes, 1986;Nunan, 1989;Skehan, 1996a;Wills, 1996).Based on the previous literature, we drew the definition of a pedagogic task as "a goal-oriented activity involving information or opinion gap in an authentic context carried out by learner in ways of communication with predictable outcome that can be evaluated".According to Jeon and Hahn (2006), TBLT provides learners with natural sources of meaningful material, ideal situations for communicative activity, and supportive feedback allowing for much greater opportunities for language use.In addition, many researches also claimed that task-based language assessment is a crucial element in task-based language teaching.( Van den Branden, 2006b;Norris, 2009).Thus, TBLT is inseparable with a consistent assessment or evaluation (feedback) system.TBLA is not an unidirectional formative language testing with single criteria, nor one-way verbal slash written feedback focusing on error-correction provided solely by teachers.It now has a growing number of alternatives characterized by playing its role of promoting students learning process, developing learners' autonomy and self-regulation capacities, as well as enhancing cognitive competencies in sociocultural and SLA perspectives.For example, Carless (2015) developed co-assessment (also called collaborative assessment and cooperative assessment), which is a combination of teacher assessment, peer assessment and self-assessment in his study.In many research, experiments had been carried out showed that co-assessment generated positive effects on students development towards judgment (Falchikov, 1986;Stefani, 1992), and learning cognition (Hyland, 2000;Yellow & Topping, 2001;Yang et al., 2006).Carless (2011) found that a sustainable feedback framework would support students in self-monitoring their own work independently of the tutor, which supposedly enhance students' self-regulative capacities.Hirose (2012b) surveyed EFL students in Japan concerning their perceptions of bi-modal peer feedback in the form of written feedback and oral interaction.The results showed that written-plus-spoken peer feedback is a promising combination that helps to enhance students' motivation and potentially improve their writing ability.
The literature above illustrates that task-based language teaching and task-based assessment, sometimes called task-based evaluation, have a crucial role in promoting students competence at cognitive and language acquisition level.However, few researches had been conducted to provide a practical example of how to implement TBLT and TBLA in teaching practice.In light of this, this study is based on a fundamental re-conceptualization of the task-based language teaching process and assessment model, aiming to discover its potential impact on students' competence.Over a period of one academic year, 8 systematically designed tasks in accordance with the context of the course were put in the place of analyzing.The paper draws on an English comprehensive reading class experience with 30 students in distributed group setting.Classes met for ninety minutes three times a week.The study's attempt is to explore students' perceptions on benefits of tasks and task-based assessment.This research is supposed to provide insights for college teachers to design and implement any systematical communicative tasks, which is of vital to develop students' competence in different perspectives.

Framing the Systematical Designed Task and Assessment
Wills (1996) presented a typical task circle framework for task-based learning with specific explanation on its sequencing stages and attached the importance on using language to exchange meaning.The result showed such framework provides optimum conditions for language learning.Skehan (1996) also sequence the steps which was known as "weak" forms of TBLT.Such frameworks are considered weak form on the grounds that tasks are comparable to the production stage in PPP model.In another regard, Ellis made a three-phrase task as a frame work for designing task based lessons.It consists of pre-task, during-task and post-task.More related framing tasks could be found on plenty of researcher (McCarthy, 1998;Salaberry, 2001;Nunan, 2004).
The notion of frameworks varies with pedagogy and methodology.It is hard to reach a consensus on which framework is the best and will bring about the fullest advantages.As Ellis noted in his book (2003), what constitutes the main activity of a lesson is largely a matter of perception and therefore, to some extent at least, arbitrary.Therefore, for the benefit of research project, the model of Ellis is adopted in this research except that the procedures are not implemented in the same way.

Pre-Task Stage
This stage is on the purpose of introducing new topics or themes of the task, preparing students with well-organized context structures and forms of language, setting up a model of what and how students will be required to carry out the task.
1.2.1 Procedure 1. Schema-Make Students Understand the Theme Cook (2011) noted that the problem with reading is not just the language, but the whole process of getting meaning from text.L2 learner have "cognitive deficits" with reading that are not caused so much by lack of language ability as by difficulties with processing information in a second language.Lack of background information could be an obstacle for L2 learner in the processing of acquiring a second language and a reason for reducing students' motivation in reading.
Therefore, to make students understand the theme, the teacher should be in the position to supply with adequate background knowledge or schema before students tackle with the text.For example, providing printed reading materials before class with a couple of questions attached, requiring students to watch a theme-related video and make a brief summary on it.It is also advisable to assist learners do theme-based research.It is thought to develop students' receptive skills and self autonomy, as well as enhance their motivation in a higher level reading.At this point, teacher is not "knowledge provider" but "information supplier", which two items are crucial to be distinguished, because unlike in traditional model teacher does not bring knowledge to class in a unidirectional way instead they stimulate student to acquire knowledge by self-learning.The plausible interaction is between staff and students by questions and answers.Vygotsky (1978) believes that the role of education is to provide learner with experiences within their ZDP, thereby encouraging and enhancing their individual learning skills and strategies.Ellis (2003) further applied this notion into task-based learning and teaching.He mentioned that tasks must be structured in a way that they pose an appropriate challenge by requiring learners to perform functions and use language that enable them to dynamically construct ZPDs.Thus, in this process, explicit instruction could be the most appropriate approach to achieve this objective as it helps students scaffolding certain knowledge based on what they already learned.Archer (2011) demonstrated three features of explicit instruction: systematic, relentless, and engaging.It is particularly tailored to students' learning and attention needs, which is not explanation but modeling and guided practice.Explicit instruction enables students to decode the information, comprehend them and integrate small units into meaningful wholes whose process supports learners to internalize new structures and skills.
What is the way the writer uses to carry out explicit instructions?Below is a sequence of steps setting as an example for scaffolding students' cause-effect writing device.  1 demonstrated many advantages of TBLT.First, by acknowledging learners' actual knowledge, it enhanced their confidence to get in the position for new skills and strategies.Second, students' active engagement in interactive communication has been constantly developed when they tried to make sense of new information with a clear setting goal and specific instructions.Finally, it enables students to perform structures and language to dynamically construct ZDPs with teacher's assistance, resulting in internalizing new knowledge.During the sequences, the teachers understand learners' thinking, provide scaffolding and stimulate them in cognitive work, gradually helping them comprehend it.Thus, the teacher is here for guidance and careful monitoring and providing immediate affirmation constantly.

Procedure 3 Preparation Activities
Learners at this stage can be given enough time to plan how to perform the task.Ellis (2003) illustrated two major methodologies options; one is that the students simply are given the task work plan and left to decide for themselves what to plan, while the other is that they are given guidance in what to plan.For my concern, I developed a compromise solution for this stage.Students need to meet the basic task requirements on the purpose of developing either linguistic or cognitive competence, but they are left to plan what content to put in the place and how they will perform the task.The example of planning procedures is illustrated in

Teacher's clarification on new skills
Teacher: Now discuss with you partner, highlight cause and effect sentences in these three pieces of writing and tell your peers their ways of connection.

Students engagement
Students were first introduced to the idea of an interview with a topic question.They were distributed to interviewees in different identities in case of overlapping.During this process, students were provided with strategic instructions like "discuss with your group members on interview questions beforehand.", or language instructions "use the vocabulary in your textbook".This part gives additional exposure to topic-related inputs and increase students' experience of the target language in use.Task preparation usually lasts for 3 to 4 weeks.It's of great importance to introduce guided planning instructions as detailed as possible.Foster and Skehan (1996) found that when students were given detailed guidance they tend to prioritize content with resulting gains in complexity when they performed the task.As for its condition, after the interview, each group need to present it in front of the class in oral English and hand over a written report afterwards.Before their performance, students will be required to discuss assessment items either with teachers or peers.This step should not be omitted as it guided a direction of how their performance will be judged and evaluated, for example, when the item "if your group members were equally contributed to the task" were put in the evaluation format, it is plausible for task-takers to take it into consideration and distribute their duties properly, which effectively prevents the scenario that only one or two members being in charge of every performance.Table 2 is an example of detailed sequence with rich instructions and sufficient communication.

The During-task Phrase
This phrase demonstrates how tasks being performed by students and what they should do during this session.

In-Class Presentation
Group presentation: Usually students in each group were given approximately 20 minutes in total to deliver a speech with the content of the process of preparation, the interviews with shared opinions, and the findings after the interview.The content of their report largely depends on what insights they have on different issues.
Individual duties: Students report their findings separately in the form of a prepared speech or power-point presentation within 3 minutes.Either in group or individual presentation, the audience is encouraged to propose any critical questions after the presentation if they have any to challenge the speaker.For example, the unidentified items or new words, the incomplete content of presentation, or logical fallacy.It has a great many benefits for both listeners and speakers through in-class observation.First, considering on-the-spot feedback, it helps the speakers to notice errors they made or overlooked language points in presentation.Second, it effectively gets students a lot more involved in other students' presentation.Furthermore, it facilitates the development of the listeners' logical thinking.
For example, in one in-class presentation, whose task is to design a course syllabus for primary students, the speaker (student A) claimed that the syllabus our group designed is best suitable for primary students because it is interesting with many games to play instead of overwhelming homework to do, then one of the listeners (student B) challenged the speaker with the question "Why playing interesting games would be best suitable for primary students?"The speaker failed to give a reasonable response on the spot, but she reflected in her self-evaluation as followings, "I should think over and give a more convincing opinion next time".This example showed that challenging questions from peers may increase the students' sense of self-improvement.Thus, teachers should set up models and encourage students to get more involved in.
1.3.2Teacher Assessment, Peer Assessment and Self-Assessment When groups are making presentation, the teacher and the rest of students have to conduct a formative assessment on a technology basis.Many researchers have applied various online tools to support peer assessment and self assessment (Raban and Litchfield 2007;Luxton-Reilly 2009), which proved to be less time consuming than paper work.
Students can enter the previously discussed assessment criteria online beforehand.It would enforce them to acknowledge those assessment criteria, in accordance with which, adjusting their performance, and to which extent develop their self-regulated capacities.
1.3.3Criteria of Tasked-Based Assessment Language assessment criteria have been constantly adjusted based on different types of tasks and its performances.For example, group working tasks will be assessed considering the factor of contribution equally to the task to grantee each student develop the sense of teamwork spirit and actually evolved in the tasks for separate onus.However, this criterion will be removed if it is an individual performance.Nevertheless, most task criteria cover the following aspects: content, organization and delivery.

Sample of assessment criteria of an individual-work on presentation 1.The above pictures are samples of three different tasks with different items of criteria, which were established on a goal-orientated basis.Criteria items were adjusted in each time, which highly depending on its tasks and students feedback on previous assessment.It follows the principle of complexity-accuracy-fluency in TBLT, which are frequently used in task performance description by many researchers (Skehan 1989, Ellis 2003).
Post-task phrase: Assessment and evaluation (feedback) Feedback has long been regarded as essential for the development of second language (L2) writing skills, both for its potential for learning and for student motivation.(Ken Hyland&Fiona Hyland 2006) Post-task will mainly focus on self reflections on tackling the tasks and evaluations consist of peers evaluation and teacher evaluation.This includes: 1) Students write down a self-reflection on the process of how to conduct the task, and their general performance in the "during-task" phrase.
2) Students write down a peer evaluation for their peers.
3) Teacher writes down a teacher evaluation for each group in three different dimensions: a) Comments, b) Language Focus; c) In-class Presentation.
In the comment section, the constructed teacher evaluation has placed great stress on the complexity of the task and the richness of students' performance, as well as their strength and weakness.The content of comments section follows the principle of acknowledgement, praise and suggestions.
Picture 2. Structure of teacher's evaluation Normally the evaluation will contain the following sequence as a A-P-C module.
1) A refers to Acknowledge what they have done.
2) P refers to either Praise or Problems .
3) C means critical questions proposed by teachers expecting to be responded later on.

Sample of Comments
Your group had a dramatic performance on the video, which is hilarious and cute.You've also asked the dorm-keepers a bunch of thoughtful questions.These questions are different and meaningful with careful thoughts.I hope that you would benefit from not only the practice but also dorm-keepers' answers.

→(Acknowledgment)
All your team members are hard working and able to complete it carefully and completely.I do appreciate your quality work to do it well and everyone's contributions to the dubbing except that I am a little concerned about your language accuracy.Some language being used in the subtitles are directly translated from Chinese into English which sounds very Chinglish.So double check your translation before type it as your subtitle.
→( Praise, Problems and Suggestions) The first part acknowledged what they have done, following with constructive suggestions.It's plain to see that language used in this comment are positive and encouraging instead of criticizing, such as thoughtful and hard working.Besides suggestions are given in an acceptable way by saying "maybe you could...."; "I personally believe", not "you should", which is much better than make students take it as an obligation.Such scaffolding provided by the teacher helps to build the students confidence and motivation to which extend enhancing their task process in the next round of tasks, and helped to build up a trustworthy relationship between the teacher and students.Just as Carless (2016) claimed that relational aspect of feedback are salient in that feedback is an aspect of interpersonal communication.Comments are vary with tasks, which should by no means made as the discussed sequences and forms.Oral comments are also effective and less time consuming.
The second section of feedback stressed the importance on the accuracy of learner's language through error corrections.Last part is to evaluate learners' task-performance in pronunciation, intonation, sentence stress as well as non-language features in a speech delivery, such as confidence and other non-linguistic strategies.Each student's performance will be recorded for the evaluation of their oral language competence.
A combined co-assessment and evaluation enable greater focus on formulation and monitoring.Learners are also enabled to give and receive reflections from different perspectives, which is expected to stimulate their autonomy and motivation.

Summary
The above mentioned process offered a framework of TBLT with detailed processes.An overview of this framework can be seen in Diagram 1.Some characteristics of TBLT should be pointed out in this framework: 1) Pre-task is significant for inputting new information to learners, which means tasks can not be carried out with no meaning and no target language.Just as Nunan ( 2001) claimed, reception should come before production and extensive opportunities for listening and reading should precede speaking and writing.2) Technology-facilitated tasks is particularly applicable in a large-sized English teaching context in China.For example, tools such as Xmind can be used to organize the structure of texts, Wechat groups with assigned tasks can be used for discussion, while Wechat Public Platform allows students to publish their own work and get comments from people outside classroom.WJX.cn is a website for collecting and analyzing data, and it can be used in co-assessment stage.3) Under such framework of TBLT, teacher's role has been changed dramatically.The teacher has come to play the role of a task-designer, material provider, a collaborator and an evaluator.

Research Questions
The study addressed the following research questions: 1) In which aspect of competence does the participant improve over a year TBLT approach in the Intensive-Reading courses?
2) What types of tasks will bring positive effects in their English learning processes and why so?
3) What does the learner think of the assessment and evaluation system?

Participants
Thirty one students between the age of 18 to 20 were enrolled in the course, 5 boys and 26 girls, whose first option in choosing major is English language.The average scores of their English language test in College Entrance Examination is 122 points out of 150 in total, which was considered at intermediate level.

Grouping
The arrangement of seating was random initially owing to a lack of comprehensive learning of each individual.
Yet over the time passing by, deliberately switching deskmates occurred considering student levels of oral English skills, dispositions and capacities including creativity, communication skills, and organizational abilities.Some irresistible conditions existed in the course of research processing such as group members withdraw from school, new members being placed in the class, and students incidentally asking for leave with one or two undone tasks left.Hence the raw data were not completely evenly-collected, but it would not have much severe effect on the implication of the research.Each group guaranteed with a boy and 3 to 5 girls on the grounds that boys in this classes were extrovert and thought to activate the group as a whole.The hypothesis has its way that gender difference would enhance the effects of grouping.

Research Instrumentation
To investigate what competences have been enhanced by this TBLT framework and its influential factors, the study uses a combination of interview data, learners' portfolio and questionnaires.Data-collecting began from September 2017 to June 2018, lasting 28 teaching weeks with 4.5 hours for each week and 1.5 hours for each class.All recordings and tasks were made during scheduled classes by the writer who took over both roles of teacher and researcher.
The following instruments were used in this study: 1) Questionnaire and interviews The questionnaire with several open questions and scale problems has been designed by the researcher, aiming at investigating students' perceptions on the effects of TBLT in three dimensions including motivation and attitudes, competences and language skills.Also the researcher has conducted a face-to-face interview with all participants.
2) Students portfolio and classroom observation All task performances had been recorded for the evaluation by video typing or reports.Both e-portfolio and paper files had been developed, which includes paper work, video records, revised PPT, posters, as well as assessment records based on the tasks.

Data Analysis
The first research question is which type of tasks do students prefer and why?Four types were put into a multiple question, including interviews, making posters, impromptu speeches and designing (a travel plan, a syllabus, or a pair of brand-new shoes).Hence, as it shows in Table 8, there were 26 students (76.67%) and 9 students (30%) put designing and making posters as their options.As for reasons underlying such choices, they can be summarized as followings: First, designing stimulates their innovation and creativity which enables them to put new ideas into practice.Second, designing is a long process of learning during which they were provided with more opportunities to discuss and negotiate with team members and search for various back-up materials on one's own initiative.Lastly, it is interesting and has close connection with real life.Other tasks such as interviews and impromptu speeches were also considered as challenges by some students (23.33% for both) to take because these tasks allow them to communicate with different people and know their thoughts which could be very useful in their future jobs.It is obvious that diverse tasks can be quite influential in turning students into autonomous self-regulating learners, building their interpersonal capacities and enhancing their motivation of both linguistic and non-linguistic learning."Designing" is a task which highlights critical thinking, problem-solving ability and teamwork competences.Interviewing carries rich opportunities to learners in communicating with people holding different minds and thoughts, which shapes learners' way of thinking.Tasks applied in this teaching practice shed lights on authenticity, meaning-focused and student-centered qualities.
Both type D and type B in Figure 3.2 are tasks with high cognitive demand and more complex communication.3. I was less sacred of making mistakes or embarrassment.
4. I was able to talk more than before.
5. My interaction and quick response has improved.
6. I've learned some words and expressions that can be used on a daily basis.

Effects of TBLT in writing 1.I made less grammatical mistakes.
2. I've learned how to make a well-organized writing.
3. I've learned to use some advanced vocabulary and figure of speeches in my writing.
4. I've developed a good habit of making an outline before writing.

Effects of TBLT in reading comprehension
1.I gained some new thoughts and ideas from different texts.
2. I have extended my vision in different areas.
3. I learned many new words and expressions which cleared up the blocks of reading.
4. The ability of analyzing 5. Deep thinking 6.I can better understand the main idea and cultural differences revealed in a text.
7. The reading speed had been increased.
From all these perspectives, it's clear to notice that TBLT had bring many positive impact on students language competences in speaking, writing and reading comprehension aspects.In this practice class, more than half of the students classified themselves as introverted people.Some of these students claimed that their challenge in English learning especially in speaking is partially because of their personality that they are very much afraid of making mistakes and being mocked by others.While others also said they don't speak their opinion out is because they don't know what to say.Yet TBLT provides rich instructions and materials on speaking to deduce their intentions and anxieties.TBLT approach boosts students self-confidence which proved to be the best predictor of language proficiency.(Clement, 1986).Linguistic self-confidence contributed to learning in foreign language learning situations where the learners had little contact with the L2 outside of the classroom.(Clement Dornyei & Novels, 1994) Either being required to communicate with team members in a small group or give a summary speech in front of the whole class, they gradually developed a positive attitude in English speaking and some may even reach the goal of fluency to some extent.Cook (2011) mentioned that the goals of language teaching include changing people's attitudes towards other cultures and using second language effectively.In reading aspect, students are in the position to accept cultural and ideological frames from different perspectives, which may help them become critical thinkers and insightful readers.The schema theory applied in this reading practice class added up new information, accounted for comprehension and raised learners' cultural awareness.
Students also learned to think deep in reading a text instead of merely focusing on language, which makes a meaning-focused not language-focused class.The writing part clearly demonstrated that learners' logical thinking and organizing ability has been trained and enhanced, though a few students found no improvement.These three open-ended questions offered the answer to what impacts will TBLT bring on students language competence.
By comparing the performance in two speaking assessment and recorded video, students are found to be more confident and willing to share their thoughts and opinions with either the teacher or their peers.Learners' performance had been appeared to be produced greatly in complexity, fluency and proficiency.
Furthermore, data analysis will be laid on other aspects of competences as followings.
Tablet 5. Students perceptions on tasks (Question 1 to Question 7) Questions M SD N 1.Some tasks are closely related to the real life.Question1-6 demonstrates that students have generally responded positively toward designed tasks.They acknowledged the authenticity of tasks and practical advantages of these tasks which developed some prospected non-linguistic skills, such as logical analysis approaches, collaboration skills, interpersonal communication and specific techniques, namely, video editing, constructing, and dubbing.In the task-conducting processes, actual language use was also promoted when students have more chances to do research or talk to people in English, as it shows in Question 7. It also reflected that the TBLT approach somehow spurred learners' instructional motivations in the process of learning which appears to be very much powerful in the context where learners have no opportunities to interact with target-culture members as investigated by much of the research (Gardner and Lambert 1972;Masgoret and Gardner 2003).Question 4-5 rests on learners' intrinsic motivation with which learners' curiosity for new knowledge is aroused and sustained.And as a result learners gain pleasure and internal satisfaction from those task experiences which also guarantee the learners' activity engagement.Except what demonstrated in the questionnaire, the class observation also revealed learners minor change in each time.Take Student A for example, in the first speaking assessment, she talks with the teacher quite nervously, repeating a simple word over five times to finish a sentence and avoiding eye contact with the teacher.As time went by, under the encouragement of group members and group speech practice(each group member has to give a speech in front of the rest), the student volunteered to give speeches in a more fluency way.I made a summary of her improvement in the face-to-face interview: I think I am more confident than before.I am not afraid of making mistakes because my group members always make mistakes and we do not blame them for that.I should practice my oral English more and improve myself in the future.I think our team is the best.The last part investigates learners' perceptions on assessment in TBLT.As it displays in Table 3, 9 out of 30 students (30%) chose co-assessment that is teacher assessment, peer assessment and self assessment.And 7 students (23.33%) hold the opinion that teacher's and peer assessment are a good combination for evaluation.Only 2 students (2.33%) reported that they would choose either peer assessment or self assessment.This chart reflects that teacher assessment is irreplaceable and plays a more significant role than the other two in the assessment system.Either interviews with students or data derived from Q14-16 reveals the fact that students was in less favor of peer assessment and self assessment (Mean<4).Many students spoke their attitudes freely on peers and self assessment.Although some students hold a positive opinion towards peer assessment and self assessment, taking it as a way of learning and enhancing critical thinking, others are oppose to these two.Some of the standpoints against these two are summarized as followings: 1) I don't like peer assessment because it's hard to get/give specific suggestions, some of which are generalized.2) Either self assessment or peer assessment are quite similar in each time.They are tedious and not constructive at all. 3) To make peer assessment and self assessment are too much time-consuming.4) I don't like self assessment is because I am at a low level of self-cognition and I am not confident enough.From all these perspectives, it is plain to see students admits the importance of assessment and its various forms, yet which one to choose and how to make it effective should give proper concern.The last question, Question 18, offers a generalized non-linguistic competence that has been improved through TBLT based on students personal views.As it shows in the chart, organizing, critical thinking and attitudes of learning English ranks on the top three.The next follows with problem solving capacity and the ability of analysizing a problem.Students evaluating expertise receives the least recognition.

Limitations
The study was limited as followings: i.Many factors which proved to make influences in second language acquisition had not been taken into consideration for detailed analysis such as gender differences, personality traits and levels of learners' language proficiency.
ii.This experiment was conducted based on the researcher's own teaching practice with comparatively fixed number of students, so no experience or control group had been set up for research comparison.
iii.The teaching objective of intensive reading course in the department is to develop learners' whole-person competence instead of training their specific skills.Assigned tasks are vary with different focuses.Therefore, the study did not provide enough quantitative data on learners' language competence enhancement.

Implications for English Teaching
TBLT framework can be taken as one of the contributing factors to reconfigure current pedagogy and curriculum.Yet there are some points to notice.First, since students have accepted different methodologies before being enrolled in the college, it could be a challenge for them to take TBLT completely and develop an independent learning habit.Thus, TBLT should be well-organized and designed in the curriculum, serving for different teaching objectives so as to lessen their repellent.Second, before each task a clear goal or a desired outcome as learning motivation should be pointed out, making learners realize the objective of each task.Third, task-based teaching involves a high level of creativity and dynamism, which is also a challenge for teachers who have been taught by traditional teacher-centered methodology and have very limited access to it, in that case, teachers should be familiarized with this approach either by some relevant training such as TESOL, TEFL, and CELTA or published guidelines.In addition, even if TBLT carries the features of meaning-focused tasks, authenticity and social communication, it by no means understates the production of each context, like the theme or values involved in and its language use.Thus, a ideal combination of real-life tasks and output of theme-focused context is a must.Some tasks may not be interesting or enjoyable, but they could be very useful in the whole process of English learning.However, obvious enjoyment by the students is not necessarily a sign that learning is taking place.(Cook, 2011).Some tasks could be even complicated and challenging, which may leads to learners' passive attitudes towards conducting a task.Hence, teacher should transfer their role of instruction-giver to a psychological assistant, consoling learners whenever their negative emotion occurs.In terms of co-assessment in the last phrase of tasks, teachers should exemplify the contents and standards of assessing, and help learners to develop evaluation consciousness and expertise.As Xu and Carless(2016) reviewed in their study, teachers need to provide guidance on assessment requirements (Evans, 2013), to help students generate or use criteria (Rust, Price, & O' Donovan, 2003), to teach them how to analyze and use exemplars (Hendry Armstrong, and Bromberger 2012) and to clarify the student role as an active participant (Evans, 2013).

Conclusion
The primary purpose of this study is to construct a framework of TBLT approach and an assessment system serving for this methodology based on the researcher's own teaching practice.In the finding part, the study investigates the effects of TBLT on the development of students' competence in the perspectives of thinking, doing, cognition and second language acquisition.I suggest the framework of TBLT in the intensive reading class should be consisted of three tasks, including pre-task, during task and post-task.Pre-task stage is a preparation for tasks in which the topic or theme will be introduced and students will be offered with sufficient information to bridge the cultural or language gap.Before a designed task conducted by students, a systematic sequence of carrying out the task and criteria of assessment will be noted as well.The next comes to during task stage when students, usually in groups, will perform it in the way of oral presentation or written report.Meanwhile, the rest of peers and teacher would assess their performance in a formative assessment.Last step is the post-task stage which can also be regarded as the reflection stage.Both teacher and students need to conduct a evaluation for another group.The author formulates three components of evaluation report including comments, language focus and in-class presentation, which matches up with complexity, accuracy and fluency in TBLT.
Comments are supposed be positive with constructive suggestions to support future tasks and facilitate learners' motivation and confidence.
The second part of this article probe effects of TBLT in this teaching practice from students perceptions.It is found in this study that tasks require innovation, decision making and teamwork are most popular among students.Decision-making is significant in the learning process, just as Bachman (1964) indicated that involving learners in decision-making tended to lead to increased motivation and thereby, to increased productivity.
The designed tasks spur the development of new ideas and involve abundant opportunities to access the target language, besides since the task is conducted within a group, it helps to enhance the interrelationship between students.The benefits and effects of TBLT in this study were elaborated in both linguistic and non-linguistic aspects.Firstly, TBLT develops learners' capacity of self-improvement and self-autonomy.It also encourages learners' intrinsic motivation.Second, TBLT provides a cooperative learning environment which simultaneously enhances learners' interactive communication skills and self-determination.TBLT improves learners' organizing skills, critical thinking and changes their attitudes of English learning.Assessment system is an inseparable part in TBLT.And teacher assessment should go before self-and peer assessment.
This article manifests that most of students are in favor of TBLT because of its real-life authenticity and communicative interactions.It changed the passive, teacher-centered class into an active, student-centered class, which highly enhanced students' engagement in a second language learning, especially in China where learners have little chance to expose themselves to an English speaking environment.Though advantages of TBLT are there, it should be applied sensibly taking many factors into consideration, including levels of participants, teaching materials, feasibility of tasks, curriculum, time settings and teacher's capability and personality.
