7、arning styles might be thought of as“cognitive,affective,and physiological traits that are relatively stable indicators of how learners perceive,interact with,and respond to the learning environment.,Styles and Strategies,3.L2 learning styleIn the enormous task of learning a second language,one that

8、 so deeply involves affective factors,a study of learning style brings very important variables to the forefront.Such styles can contribute significantly to the construction of a unified theory of second language acquisition.,Styles and Strategies,Learning styles mediate between emotion and cognitio

9、n.For example,a reflective style invariably grows out of a reflective personality or a reflective mood.An impulsive style,on the other hand,usually arises out of an impulsive emotional state.Peoples styles are determined by the way they internalize their total environment,and since that internalizat

14、专注，不易分心。认知功能较为独立，通常能不受制于所給予的讯息而进行认知重建的工作。具有较高的分析能力，比较能区分视觉界中形象与背景。面对复杂、不确定的情境，较能有效的去组织、结构。,Styles and Strategies,场地独立型个体学习与记忆历程的特征为：(1)采取參与者的角色，主动地介入讯息的接收；(2)广泛选择采用各种可用的线索，能依工作需要建构所需场地；(3)忽略不相干的部分而萃取出重要的部分，较会运用中介历程区分一连串的刺激；(4)较常使用整体策略的假設考验方式來获得概念；(5)概念的自由回忆效率较高。,Styles and Strategies,隱藏图形測验是將一个單純的几何

15、图形隱藏於复杂的图形中，使之不易辨识。受試者被要求在此复杂的图形中找出被隱藏的单純图形。受試者的得分就是发現简单图形所需的時間；時間愈短，表示受試者洞見目標的能力愈強，比较不被图形的复杂迷惑。換言之，其知觉特质是能夠把形象从場地組织背景中独立出來，故称为場地独立型。如果所需時間愈長，表示受試者的知觉被整个场地的組织強烈支配，場中的各部分成为混杂的经验，无法独立出來被确认，故称为场地依賴型。,Styles and Strategies,B.Field dependence(领域依附感)definition:perceiving the whole,not the parts embedded w

18、hypotheses:1.Field independence is closely related to classroom learning that involves analysis,attention to details,and mastering of exercises,drills,and other focused activities.,Styles and Strategies,2.Primarily field-dependent persons will,by virtue of their empathy,social outreach,and perceptio

25、s and Strategies,3.Ambiguity ToleranceThis style concerns the degree to which you are cognitively willing to tolerate ideas and propositions that run counter to your own belief system or structure of knowledge.Open-minded people accept ideologies and events and facts that contradict their own views;

26、they are more content than others to entertain and even internalize contradictory propositions.3+,Styles and Strategies,ambiguityThe lamb is too hot to eat.1.2.face:human face;face of a clock;cliff face;face value;face lifting(整容),Styles and Strategies,在第二语言习得的过程中,英语学习者不可避免地要面对许多心理因素的困扰,特别是模糊容忍程度的高低

27、往往能决定学习的最终效果.传统的观点认为模糊是指对词和句产生两种以上的不同理解,它阻碍学习者的正确学习;而认知心理学家却指出,外语学习过程就是从模糊到确定的逐步递进的过程,对模糊的容忍在语言学习过程中标志着认知的发展.针对这一现象,在具体分析英语学习者的认知学习风格、语言学习策略以及自我关注等因素的基础上,研究者对模糊容忍与学习者之间的关系进行了阐述.结合当今中国大学英语教学现状,对大学生在英语学习中的模糊容忍性的各种变因进行了探讨、分析,并提出在英语教学中,要充分考虑模糊容忍性的平衡关系,从而提高学习效果.,Styles and Strategies,调研结果(1)在英语学习成绩方面,高歧义

28、容忍度的学生显著优于低歧义容忍度的学生,中歧义容忍度的学生显著优于低歧义容忍度的学生;(2)高、中、低不同歧义容忍度的学生,在焦虑水平上存在显著差异,Styles and Strategies,歧义容忍度与认知、学习动机、学习风格等因素紧密相关,在外语学习中歧义容忍度低的学习者面对意义不明确的刺激时会体验到压力、出现消极反应和回避性反应;容忍度高的学习者对意义不确定的刺激感兴趣,不会否认或歪曲其复杂性.培养学生的歧义容忍度有助于促进外语学习.,Styles and Strategies,Advantages:The person who is tolerant of ambiguity is

29、free to entertain a number of innovative and creative possibilities and not be cognitively or affectively disturbed by ambiguity and uncertainty.In second language learning a great amount of apparently contradictory information is encountered:words that differ from the native language,rules that not

30、 only differ but that are internally inconsistent because of certain“exceptions”,and sometimes a whole cultural system that is distant from that of the native culture.Successful language learning necessitates tolerance of such ambiguities.,Styles and Strategies,Disadvantages:People can become“wishy-

31、washy”,accepting virtually every proposition before them,not efficiently subsuming necessary facts into their cognitive organizational structure.Such excess tolerance has the effect of hampering or preventing meaningful subsumption of ideas.,Styles and Strategies,Ambiguity Intolerance:the closed-min

32、ded people are more dogmatic,tend to reject items that are contradictory or slightly inconsistent with their existing system;they wish to see every proposition fit into an acceptable place in their cognitive organization,and if it does not fit,it is rejected.,Styles and Strategies,Advantages:A certa

33、in intolerance at an optimal level enables one to guard against the wishy-washiness referred to above,to close off avenues of hopeless possibilities,to reject entirely contradictory material,and to deal with the reality of the system that one has built.,Styles and Strategies,Disadvantages:It can clo

34、se the mind too soon,especially if ambiguity is perceived as a threat;the result is a rigid,dogmatic,brittle mind that is too narrow to be creative.,Styles and Strategies,Strategies:1.Learning strategies munication strategies 3.learning strategy training,Styles and Strategies,Strategies(definition)S

35、tyles are general characteristics that differentiate one individual from another;strategies are those specific“attacks”that we make on a given problem.They are the moment by moment techniques that we employ to solve“problems”post by second language input and output.The field of second language acqui

36、sition has distinguished between two types of strategy:learning strategies and communication strategies.,Styles and Strategies,The former relates to inputto processing,storage,and retrieval,that is,to taking in messages from others.The latter pertains to output,how we productively express meaning,ho

37、w we deliver messages to others.Characters of good language learners:P114xx,Styles and Strategies,1.Learning strategiesTypically,learning strategies are divided into three main categories.A.Metacognitive strategy(后设认知策略)；B.Cognitive strategy;C.Socioaffective strategy(社会效果策略)4+,Styles and Strategies,

38、A.Metacognitive strategy is a term used in information-processing theory to indicate an“executive”function,strategies that involve planning for learning,thinking about the learning process as it is taking place,monitoring of ones production or comprehension,and evaluating learning after an activity

40、ture P116xx,Styles and Strategies,B.Cognitive strategies:are more limited to specific learning tasks and involve more direct manipulation of the leaning material itself.Cognitive strategies refer to processes and behavior which learners use to help them improve their ability to learn or remember som

41、ething,particularly those which learners use with specific classroom tasks and activities,e.g.Repeating key words or phrases silently or aloud;summarizing to make sure the important information will be remembered;creating visual images to help them remember new information.P116-117,Styles and Strate

42、gies,C.Socioaffective strategy:has to do with social-mediating activity and transaction with others.P117,Styles and Strategies,2.Communication strategiesWhile learning strategies deal with the receptive domain of intake,memory,storage,and recall,communication strategies pertain to the employment of

43、verbal or nonverbal mechanisms for the productive communication of information.In the arena of linguistic interaction,it is sometimes difficult to distinguish between the two,since comprehension and production can occur almost simultaneously.,Styles and Strategies,According to Taron there are four b

44、road strategies:A.Avoidance(syntactic or lexical avoidance,topic avoidance,e.g.P119-120)xxB.Prefabricated patterns(事先组织好的句型)(Tourist survival language e.g.P120)xxC.Appeal to authority(native speaker,dictionary,teacher,electronic device)D.Language switch(native language,body language)Some other commu

45、nicative strategies?,Styles and Strategies,Learner Strategy Training Definition:teaching learners how to learnLearner strategies is the key to learner autonomy,and that one of the most important goals of language training should be the facilitating of that autonomy.P126-127,Styles and Strategies,Fou
