  3. Second Language Acquisition Research • “Practice makes perfect” does not always apply to learning grammar. • They( students) often fail to use it correctly when expressing themselves freely. This temporary mastery seems to happen when they are paying conscious attention to form, but not when they are trying to communicate and paying attention to meaning. • Jane Willis

  4. 根据语言习得的规律1.语法知识的记忆不能保证语言使用的正确根据语言习得的规律1.语法知识的记忆不能保证语言使用的正确 • Knowledge of grammatical rules was no guarantee of being able to use those rules for communication. Learners who were able to identify instances of rule violation, and who could even state the rule, frequently violated the rules when using language for communication. • David Nunan (1999)

  5. 2.语言知识加交际的机会比仅仅讲语法更能提高学生使用语言的流利程度与语法的准确度2.语言知识加交际的机会比仅仅讲语法更能提高学生使用语言的流利程度与语法的准确度 • Grammar + opportunities to communicate lead to greater improvements in fluency and grammatical accuracy than grammar only.Montgomery & Eisenstein(1985) • (1985年作了一个实验,实验组教语法,但课外有实践的机会。另一组只讲语法。结果实验组交际能力强。而语法测试的成绩也比单讲语法的班好,虽然他们学的语法少。)

  6. 3.学习者的参与与语言熟练程度的提高关系极大3.学习者的参与与语言熟练程度的提高关系极大 • Learner participation in class is related significantly to improvements in language proficiency. • Lim (1992)

  7. 4.基本上以“交际”为导向的课堂教学,但同时也有明确的语法讲解,要比只注重语法教学或回避语法讲解的沉浸式教学都更好4.基本上以“交际”为导向的课堂教学,但同时也有明确的语法讲解,要比只注重语法教学或回避语法讲解的沉浸式教学都更好 • Classrooms that were basically “communicative”for explicit grammatical instruction, were superior to both traditional classrooms that focused heavily on grammar, and to immersion programs that eschewed explicit grammatical instruction.

  8. 5.当学习者积极地参与用目的语进行交际的尝试时,语言也被掌握了。当学习者所进行的任务使他们当前的语言能力发挥至极点时,习得也扩展到最佳程度5.当学习者积极地参与用目的语进行交际的尝试时,语言也被掌握了。当学习者所进行的任务使他们当前的语言能力发挥至极点时,习得也扩展到最佳程度 • Language is acquired as learners actively engaged in attempting to communicate in the target language. Acquisition will be maximized when learners engage in tasks that “push” them to the limits of their current competence.

  9. Four conditions of language learning • Exposure ( rich, comprehensible input, language in use) • Use ( of the language to do things, exchange meanings) • Motivation ( to process and use the exposure: listen & read the language; speak and write it) • Instruction ( chances to focus on form )

  10. What is Task-Based Language Teaching • Focuses on the construction, sequencing, and evaluation of particular goal-related action complexes that learners carry out either by themselves (see Prabhu’s model 1987) or jointly (see Kumaravadivelu 1993) • (Candlin & Murphy 1987; Nunan 1989)

  11. The task-based approach aims at proving opportunities for the learners to experiment with and explore both spoken and written language through learning activities which are designed to engage learners in the authentic, practical and functional use of language for meaningful purposes. (香港中小学英语大纲)

  12. What are tasks? • A task is a piece of work undertaken for oneself or for others, freely or for some reward. • It is meant what people do in everyday life, at work, at play, and in between. (Long 1985:89) 任务是人们在日常生活中所从事的 有目的的活动。

  13. What people do in everyday life: painting a fence, dressing a child, filling out a form, buying a pair of shoes, borrowing a library book taking a driving test making an airline reservation writing a check finding a street destination, TASKS

  14. A task is an activity or action which is carried out as the result of processing or understanding language ( i.e.as a response). • (Richards, Platt and Weber 1986:289) 任务=人们在学习、理解、体会语言之后所开展的活动。

  15. The communicative task is a piece of classroom work which involves learners in comprehending, manipulating, producing or interacting in the target language while their attention is focused on mobilizing their grammatical knowledge in order to convey meaning rather than to manipulate form. • 交际型任务是一种涉及到学习者理解,运用所学语言进行交流的课堂活动。学生的注意力主要集中在语言的意义上,而不是语言的形式上。

  16. Listening to a weather forecast and deciding what to wear Look at a set of pictures and decide what should be done Responding to a party invitation Completing a banking application Describing a photograph of one’s family

  17. Tasks can have variety of starting point. They may draw on learners’ own input, eg personal experience, general/world knowledge, or intellectual challenge; they may be based on written text, recordings of spoken data, or visual data; they could be activities like games, demonstrations or interviews; they could be a combination of several of these.

  18. 什么不是任务 • Tasks do not include activities which involve language used for practice or display, such as ‘ Describe the picture using the words and phrases from the list below’ or ‘ Ask your partner if he likes the food listed here using the forms Do you like…? Yes, I do/ No, I don’t. where there is no outcome or purpose other than practice of pre-specified language.

  19. Role-play activities • Very often in role-play situations there is no actual outcome for students to achieve, other than to enact their roles. Students have to think of suitable things to say to each other, but they are unlikely to be exchanging real meaning. • Jane Willis

  20. 课堂任务的示例: • listening to a weather forecast and deciding what to wear • 任务的结果: • The learner will listen to a weather forecast and identify the predicted maximum temperature for the day. • 练习的结果: • The learner will listen to an aural text and answer questions afterwards on whether given statements are true or false.

  21. The essential difference betweentask and exercise • Task Task has a nonlinguistic outcome • ExerciseAn exercise has a linguistic outcome 任务活动与语言练习有着本质的区别。任务活动所谋求的效果不是一种机械的语言训练,而是侧重在执行任务中学生自我完成任务的能力和策略的培养,重视学习者在完成任务过程中的参与和在交流活动中所获得的经验。 (See example below)

  22. Success in the task is evaluated in terms of achievement of an outcome, and tasks generally bear some resemblance to real-life language use. • A task-based approach sees the language process as one of learning through doing--- it is primarily engaging in meaning that the learner’s system is encouraged to develop. • ( Long and Crooks 1993)

  23. Why do we use TBLT? • The tasks will engage students, challenge them, and allow for contingent interaction. According to Csikszetmihalyi (1993:xiv) • They have concrete goals and manageable rules. • They make it possible to adjust opportunities for action to our capacities. • They provide clear information about how well we are doing. • They screen out distractions and make concentration possible

  24. Meaning and form • The meaning versus form (or fluency versus accuracy) debate is no longer a discriminating factor among teaching approaches because meaning and form are assumed to be essential for learning (e.g., Long, 1991; Long & Robinson, 1998).

  25. A successful pedagogical task: • (a) focuses students’ attention on the structure of the language by demonstrating that language form contributes to meaning, • (b) motivates learners to heighten the complexity of the linguistic means they use to accomplish task objectives.

  26. A successful task sequence leads learners to: • (a) communicate with limited resources, • (b) become aware of apparent limitations in their knowledge about linguistic structures that are necessary to convey the message appropriately and accurately, and finally, • (c) look for alternatives to overcome such limitations.

  27. Four dimensions of teaching and learning tasks represented by the “four eyes” • involvement • inquiry • induction • incorporation

  28. The components of a task • 目标 (Goals) • 信息输入( Input Data)  语言信息(Verbal data) 如:a dialogue, reading passage, etc.  非语言信息(Non-verbal data) 如:picture, etc. • 活动 (Activities)


  30. Goal: Exchanging personal information Input: Questionnaire on sleeping habits Activity: 1) Reading questionnaire 2) Asking and answering questions about sleeping habits Teacher role: Monitor and facilitator to specify what is regarded as successful completion of the task Learner role: Conversational partner Setting: Classroom / pair work #

  31. 任务型语言教学的特点 • 1. 强调通过交流来学会交际 • An emphasis on learning to communicate through interaction in the target language. • 2.将真实的语言材料引入学习的环境 • The introduction of authentic texts into the learning situation.

  32. 3. 关注语言的本身,也关注学习的过程 Provision of opportunities for learners to focus, not only on language, but also on the learning process itself. 4. 把学习者个人的经历作为课堂学习的重要因素 An enhancement of the learners’ own personal experiences as important contributing elements to classroom learning.

  33. 5. An attempt to link classroom language learning with language activation outside the classroom. 试图把课内的语言学习与社会的语言活动结合起来。 ( David Nunan 1991)

  34. Task Analysis • Determine the objectives:Determining the final tasks so early in the planning process is the crucial and most striking factor of the framework. Everything to be done in the unit will derive from the final tasks. This way, we can really say that it is the tasks to be carried out at the end of the unit that generate the language to be used (learnt or recycled) and determine the procedures to be followed.

  35. Two primary purposes for conducting a task analysis: • 1) to develop instruction or training to support the learning of tasks identified by the task analysis; • 2) to develop some form of assessment to determine if learners have learned the tasks in question. In order to develop training and tests that are congruent with the objective (i.e. require the same level of cognitive, affective, or psychomotor performance), the designer needs to know what type of task is being learned. (Jonassen, 1999. p25)

  36. Gagne’s Taxonomy. Three types of tasks or objectives: knowledge, skills, or ability. • (A taxonomy is a hierarchical classification scheme that organizes objects or phenomena into categories. )

  37. Planning the final tasks • Final tasks are communication tasks at their highest point of communicativeness, at a level that is realistic and achievable by the students in a given class. They will serve as indicators of the development of communicative competence in a given class.

  38. Final tasks in which the students in the classroom interact • There is a tangible end product: • posters, letters to penfriends, pool information on everybody’s birthdays and produce a poster to be kept in the classroom. • Make a plan for a school outing and carry out plans and go on an outing. • Carry out a class survey on ‘who does the housework at home?’

  39. Enabling tasks • They act as support for communication tasks. Their purpose is to provide students with the necessary linguistic tools to carry out a communication task. • They can be as meaningful as possible, their main focus is on linguistic aspects (grammar, vocabulary, pronunciation, functions, discourse) rather than on meaning. • They are overt language learning experiences, whose aim is to enable students to communicate as smoothly and effectively as possible.

  40. Some types of classroom work that maybe classified as enabling task • a. Presentation of necessary new language ( functions, grammar,vocabulary, phonology, discourse features checking that the new language has been understood • b. Controlled pre-communication practice or awareness-raising tasks usually focused on accuracy

  41. Communication Tasks • A communication task is a piece of classroom work during which learners’attention is principally focused on meaning rather than form, that is on what is being expressed rather than on the linguistic forms used for expressing it. • As far as possible, resembles activities which our students or other people carry out in everyday life. As far as possible, resembles activities which our students or other people carry out in everyday life.

  42. The communicative task should have a sense of completeness, being able to stand alone as a communicative act in its own right with a beginning, a middle and an end. ( Nunan 1989:10)

  43. Categories of learned capabilities (or objectives): • Intellectual skills – subdivided into discriminations, concepts, and rules • Problem solving – combining rules or concepts to creatively solve complex problems • Cognitive strategies – skills in managing one’s learning and thinking processes • Verbal information – memorization of facts and bodies of information • Motor skills – executing sequences of bodily performances such as dancing, balancing, or handling tools • Attitudes – an emotional and cognitive propensity to choose a certain course of action (e.g. “choosing to stay late after work.”)

  44. Task classification is the act of identifying and labeling task according to the specific type of learning outcome: e.g. • 1) tasks require memorization; • 2) tasks require students to apply a rule.

  45. Merrill’s Instructional components. (1983) • Tasks included remember, use, and find. • Content included facts, concepts, rules, and principles.(Facts can only be remembered, but concepts, rules, and principles could be used (applied) or found)

  46. Planning classroom work • Three features for the design of all tasks: clarity, flexibility, and feedback • Three kinds of demands tasks place on learners: learning, content, and action demands

  47. Task training sequence • describe the overall training goals • describe the flowchart of the tasks to be learned • teach learners to name and identify work objects and actions • point out important task-relevant cues

  48. teach the necessary task-related information • teach specific procedures associating stimuli and response • teach decision-making strategies and problem solving • allow for practice of motor response • (Miller, 1962) (p41)

  49. Three Pedagogical Goals for Task-based Approaches • Accuracy 准确程度 • Accuracy concerns how well language is produced in relation to the target language

  50. Complexity 综合程度 • Complexity concerns the elaboration or ambition of the language which is produced. How far do learners rely on prefabricated phrases and established routines, and how far do they need to expand their language resources to meet the communicative challenge?
