Abstract
Since Dewey developed the concept of “critical thinking”, many scholars abroadhave carried out a series of studies about improving students' critical thinking skills ineducation field. In the 1980s,critical thinking became the target of higher educationprograms in such foreign countries as the US and Canada. It has gained its widespreadattention in China only in recent years. But there are only few studies about it ineducation field. Our traditional English teaching method pays much attention to thetraining of students' linguistic knowledge and language skills but ignores thecultivation of students' critical thinking abilities. In the process of skill practice,teachers often stress the importance of memorizing vocabulary and imitating skillsrigidly,but neglect the students' abilities in analyzing problems and putting forwardinnovative solutions. Therefore, English writing teaching is affected by this andmerely attaches emphasis to train students' reading and writing skills. There are fewstudies which aim at systematically cultivating students' analysis, synthesis, summary,comparison and reasoning skills while they are writing. Therefore,this study aims atdesigning some writings tasks and teaching strategies which can be used to fostercollege students' critical thinking awareness and promote students' all-rounddevelopment.
According to six critical thinking skills,this study was carried out by requiringstudents to hand in an argumentation. All participants in this study are non-Englishmajor college freshmen from a 211 key university. The revised version of Rubric forQualitative Critical Thinking Skills Instrument was used in this study. Withquantitative and qualitative analysis,writing experiment is conducted within a wholesemester to collect data concerning students' learning behavior. Reading-to-write isused in experimental class while traditional method is adopted in control class. Thewriting scores by the experimental and control class were statistically processed bysoftware SPSS 19.0. And also the interview was launched in some of students inexperimental class to assess students' critical thinking abilities reflected in theirwritings-The final analysis indicated that EGAP writing model exerted a significantlypositive influence in improving students' critical thinking skills, especially in arousingstudents' writing enthusiasm and critical thinking awareness. Compared with controlclass, students in experimental class made big progress in writing competence. Inaddition, this study put forward some reform proposals to the teaching of Englishwriting. The study is of great value to instruct students to employ critical thinkingskills in their writing.
Abstract
A large body of research has been conducted on the effects of technology-enhancedEnglish vocabulary learning since the 1960s (Marty, 1981)。 However, no consensus hasbeen reached yet (Choo, Lin, & Pandian,2012; Mohsen & Balakumarohsen, 2011)。
Despite the fact that some narrative reviews have evaluated and explored thesecontradictory results, this study aims at quantifying the overall effectiveness oftechnology-enhanced English vocabulary learning with a different approach to review:meta-analysis and performing in-depth moderator analyses of learning method and testtype further.
Totally, twenty effect sizes from thirteen pieces of primary research are obtainedafter collecting related literature published or unpublished in recent ten years via fourchannels and selecting through three filters. Later, all the primary research is coded anddata are computed in random-effects model with software ComprehensiveMeta-Analysis.
Results show that: (1) Technology has a positively large effect on Englishvocabulary learning according to Cohen's standards as proposed in 1992 (g = 1.26,witha 95% confidential interval of [0.86, 1.66])。 (2) Learning methods (intentional learning,incidental learning, and integrated learning) have impacts on the overall effectiveness.
Heterogeneity exists in the three learning methods (g = 9.22,p = 0,01 < 0.05)，Effectiveness of intentional learning, incidental learning and integrated learning is ^ =0.61, g 二 2.14, g = 0.98 respectively. Incidental learning under technology-enhancedenvironment yields the largest effectiveness on English vocabulary learning. (3) Testtypes (recognition tests, recall tests,recognition + recall tests) also have impacts on theoverall effectiveness. The three test types are heterogeneous as well {Q = 17.04, p =0.000 < 0.05)。 Recognition tests, recall tests, and recognition + recall tests have effectsizes of 3.59,0.71 and 0.37 respectively. Technology-enhanced English vocabularylearning achieves the largest effectiveness in recognition tests.
Abstract
The present study, which is based on the Competing Values Framework (i.e. CVF:a framework to identify the organizational effectiveness and to define organizationalculture)， aims to investigate English teachers, teaching motivation at universities, theirperception of the organizational culture in the target university,their professionalaspiration and how they affect each other. The research questions to be addressed are asfollows: (1) How do the English teachers perceive the organizational culture at theirworkplace? (2) How much effort will the teachers pay for their professionalengagement and aspiration? (3) What kinds of motivation do the English teachers in thetarget university appear to have? (4) How will the organizational culture and theprevious experience affect teachers' motivation?
This study employed four different questionnaires as the research instruments,including one demographic questionnaire and three research questionnaires, i.e. thedemographic questionnaire, the Organizational Culture Assessment Instrument (i.e. theOCAI) (Cameron & Quinn, 1999)，the Professional Engagement and CareerDevelopment Aspiration-scale (i.e. the PECDA-scale) (Watt & Richardson, 2008b)，andthe Work Tasks Motivation Scale for Teachers Teaching (i.e. the WTMST) (Fernet et al.,2008)，to investigate the above mentioned research questions. The whole investigationtook roughly 12 weeks and involved three stages: the preparation stage,the pilot study,and the main study.
The findings of the present study show that most of the teachers are intrinsicallymotivated and with identified regulation influenced by the performance culture and theclan culture which are the dominant culture types of the target research site. Results alsoindicate that the overseas experience and length of teaching experience affect teachers'perception of tixe organizational culture and motivation. The participants who haveoverseas experience tend to be more with the sense of professionalism, moreintrinsically motivated and be more confident with their competence in the academicarea; and the ones who have longer years of teaching experience are with moreidentified regulation and introjected motivation and are more committed and moreassured of staying in the education field. The participants in the target universitybasically belong to the highly engaged persisters,and the male teachers expect to be theleadership.
Abstract
Owing to the economic, social and academic needs as well as the advantages of EGAP(General Academic Purpose in Chinese College English) itself, there exist 这 great deal ofnecessity and feasibility for applying English for EGAP class. It is our understanding thatwriting plays an extremely important role in the course of EGAP and genre is a quiteinfluential factor in improving students5 writing competency. However,the investigation ofstudents' current writing situation shows that being deeply influenced by traditional writingteaching methods which emphasize grammar and vocabulary; the students have littleknowledge about genre approach theoretically or systematically and lack the awareness ofgenre. Because of this,it becomes necessary to put forward an English writing teachingapproach which is effective as well as applicable to the situation in China so as to enhancetheir writing competence.
This paper firstly gives a brief introduction to the developing trend of EGAP bydiscussing its necessity and applicability in China and the main views of two schools of genretheory, the tiieoretical foundation and genre-based approaches of three main schools of genrestudy and practice. And also,their characteristics are compared and the adaptability inChinese College EGAP class is analyzed, based on which it puts forward a modifiedGenre-based approach in EGAP writing class in order to enhance students' genre awarenessand improve their writing skills.
To achieve this, two non-English major classes of freshmen in East China University ofScience and Technology (ECUST) have been selected as the experimental class andcontrolled class, and the research lasts one semester. The Genre-based approach is applied inthe experimental class following a modified Genre-based approach. And a comparison hasbeen made on the same subject at the beginning and the end of the semester and thecomparison and contrast between the experimental class and controlled class have also beenmade. Owing to various factors,such as learning motivation, different students show variedextent of acceptance to certain teaching approaches. Therefore, emphasis has not only beenput on the overall changes,but also on the individual differences.
There are three hypotheses:
1. Can Genre-based approach enhance students' genre awareness? 2. Can “genreawareness” really improve students' writing ability in EGAP? If the students can get overallimprovement, is there any difference in gender and the students with diverse learningaptitudes because of the individual difference? If some students fail to improve, what's thepossible reason behind it? 3. Will Chinese students accept and adapt to Genre-basedApproach?
Three sets of data from six writing assignments, writing in final-term examination andquestionnaires are collected and analyzed with the help of the software SPSS 19.0. And thestudy indicates that: (1) Genre-based approach has a significant effect in sensitizing students'genre awareness, improving holistic writing competence; (2) during the whole experimentalprocess, girls have a stable superiority over boys, however, boys' improvement fluctuation iscomparatively obvious; (3) students of medium efficiency have the greatest potential to makebig improvement; (4) Unavoidably, in this research there are some students who fail to gainimprovement in terms of writing ability or get changed in terms of writing notions, andthrough analysis it has been found that the main objective reasons are: the difficulty ofwriting itself,the differences of culture and ways of thinking between east and west,thelimited teaching period, etc.; and subjective reasons mainly come from: the limitedcompetence of students themselves, the lack of interest in English writing, etc(5) aoverwhelming majority of students are liable to accept this approach and able to adapt to itpretty well, yet acceptation is not absolutely accompanied by adaptation; (6) feedback is adispensable part in English writing teaching, and more specific feedback will bring strongermotivation in students' self-correcting and developing;In the end,the author presents some limitations in her research and hopes that this cangive some hints and tips to further research in EFL writing classes.
Abstract
In college English listening & speaking classrooms, language and other semioticsystems cooperate together to help students construct meaning. It can be reflected inthe design of textbooks and the use of audios, videos and images, etc. Thus, in thisthesis, the theoretical foundation is the theory of multimodal discourse analysis (MDA)derived from Systemic Functional Linguistics and Social Semiotics. The essence ofMDA is that other semiotic resources such as: images, audios, etc. are as important aslanguage in the meaning-making system. Visual Grammar, Acoustical Grammar andthe integrated frameworks of MDA are the main analysis approaches in this thesis.
Meanwhile, the results of the teaching investigation and the MDA for textbooksare the practical foundation for the multimodal teaching design, providing feasibleand effective suggestions in this thesis. According to the results, it can be concludedthat students have more or less realized multimodality in this course and argue thatmultimodality should be used in moderation; multimodal classroom activities, socialcontent, etc. should be brought into the class; teachers should remind students to payattention to images, fonts change and other multimodal factors in textbooks.
Therefore, when conducting the multimodal teaching design, attention should bepaid to: (1) Modalities influence each other with clear priorities in this course. (2)Words modality and acoustical modality are the primary modalities, while othermodalities are just used as tools to provide supplementary information and to improveteaching efficiency. (3) The chosen modalities should provide supplementaryinformation to make the learning material more easily understood and help studentsconcentrate. Then, on the basis of the above principles and the writer's teachingexperience, a sample teaching design has been worked out, then its' feasibility andeffectiveness have been verified by an empirical study with the method of interview.
Abstract
Degree adverbs play a crucial role in daily language communication. However,owing to their wide varieties and similar meanings, it is hard for language learners toreally master their meanings and usages.
With the aid of AntConc 3.4.lw and based on the corpora of FROWN (TheFreiburg-Brown Corpus of American English)，FLOB (The Freiburg-LOB Corpus ofBritish English) and CLEC (Chinese Learner English Corpus)， the study aims tocompare the actual use of common English degree adverbs in terms of semanticprosody between Chinese EFL learners and native English speakers. The researchprocedures consist of two steps. First, AntConc 3.4.lw is launched to extractconcordance lines of the target node words in each corpus and the semantic featuresof the node words' collocates are analyzed; then, the semantic prosodies of these nodewords are summarized and comparisons are made between the two corpora.
The results indicate that there are differences as well as similarities betweennative English speakers and Chinese learners in their use of semantic prosody.
Chinese EFL learners tend to underuse the negative semantic prosodies of fairly,highly, and totally?,overuse the negative semantic prosodies of extremely; and misusethe semantic prosody of terribly. The results also show that some problems exist inChinese learners' use of semantic prosodies of degree adverbs, and the reasons mayinclude their first language transfer, intralingual transfer, and the lack of informationabout the semantic prosody in dictionaries and textbooks.

英语写作能力的培养不是一日之功，必须从平时的练习中一点点培养。巧用一些经典句型会为作文添加一点亮色，多得一点印象分。本文整理了英语议论文常用的开头和结尾，希望对大家有帮助。
要求文章结构必须十分严谨，文章各个部分的功能都要十分清晰，开头、中间和结尾都有严格的要求。英语议论文共有三大特点：

小时候，常听大人告诉我说，世界不断在变，所有你周围的东西都不会保持原有的状态一辈子的，那时候的我，还听不太懂，只是觉得奇怪，为什么所有的事物都会变，甚至变得让人完全认不出来了。就好像电影里的变脸一样。 过了几年，我已经懂事了，似乎有一点了解，所有的事物都是在发展的，就好像时间不停的流失一样，尽管发展有快有慢，但它们都会变得和以前不一样，这就是发展的魔力，也是促进它们不断发展的动力。 长大后，看见周围的来来往往的人和事，而环境也不断在变，我便完全懂得了，发展的重要性，就拿杭州就说吧。不对，若要说杭州的变化，恐怕说几天几夜也说不完了。还是缩小范围，说说文二路这一条说长不长，说短不短的路吧。 听长辈告诉我，大概在二十几年前，那儿还没有那么多的房子，而多数是农田和坟场，十分的荒凉。虽然没有亲眼所见，但大抵也可以想象得到那时候的情形。 我从小就住在那一带，当我还是小学生的时候，由于学校就在家附近，所以也就特别频繁的在那里走动，在那时候，那条路虽然比起原来要好上许多，但终究充其量也只能算是一条小小的弄堂罢了。刮风时灰尘飞舞，眼前一片雾茫茫的，而下雨时也好不到哪里去，在那里走一趟，就得洗一次鞋，因为地面上像铺了一层厚厚的泥。 现在大概已经有十年的时间过去了，文二路也完全变了一个样，它像一个成长了的孩子，正在展现着它的魅力。虽然不能和市中心比较，但也是有模有样了，路边一家家商店开起来了，然后又一次一次的翻新，马路也变宽了，汽车在上面来来往往，一副四通八达的样子。这已经不再是以前的文二路了，它代表着新世纪最显著的变化，代表着杭州正在向一个更高的层次前进。 欣喜，在于变化。
家乡的变化 我的家乡是山清水秀而又贫穷落后的。我的家在离市区几百里远的山沟里。上高中之前，我从来没有走出过大山的怀抱。老实说我对家乡的发展或是变化向来不是很关心。上高中以前没有这种意识，上了高中之后没时间关心。连两年多前到远在千里之外的他乡上大学，又懒得去关心了。因为家乡经济的发展速度跟珠三角的城市比起来实在太令人失望，提起来就伤心。 不过要说家乡的变化，我想或许可以这样做个简单的、表面的概括吧：钱多了，人“懒”了；楼高了，水脏了。 改革的春风直到八十年代后期才似有若无地吹到我们这个偏僻的山村。在此之前村里人不管男女老少都努力地在土里刨食。只是我们深爱的这片土地给我们的回报却并不多。村里除了种地再没有多少其他的收入，许多人有手艺、能吃苦，但是没个施展手艺的去处。八十年带末几年，村里人不再指望那块地了。听说大山外面的城市里有金子捡，纷纷走了出去。青年人，中年人，有手艺的，没手艺的，都想出去捡点金子回来。他们一去就是一年半载的，回来时虽然不是满身金银，总比土里刨出来的多。于是在家里歇上十几二十天的又出去了。留在村里的多是老人孩子。到了九十年代中期，连十几岁的小孩子在教室里也坐不住了，许多都挤南下打工的列车。农村劳动力少了，以前辛辛苦苦开荒开出来的地没几年又长满了野草。近几年水田也荒了许多，种地太辛苦，家里有了钱，谁还愿意自找苦吃呢？以前春节刚过没几天，田头地角便都是忙碌的身影。如今没过元宵下地似乎是很丢脸的事了。留在家里的农村妇女农闲时隔三差五就会聚在一起打牌消遣，以前想都不敢想的事啊！晴天迎着朝露出门，披着星光回家，雨天便是风里来雨里去，一年到头没几天歇的。 这几年村里的楼房就像雨后的春笋般不断从各个角落冒出来。三层四层，有的外表装修得很漂亮。即使只是一层的，算不上楼房，看起来毕竟比那些泥砖瓦房要顺眼得多。室内的装修就更不必说了，光滑得照得出人影的地砖啦，华丽的墙纸……简直是拿钱往墙上贴，拿钱往地上铺了。就是只刷上白白的石灰看上去也亮堂多了，不再像泥砖瓦房那样阴暗、压抑。 但是让人很不舒服的就是溪中的水越来越脏了。以前用不起自来水，村里人的用水都取自那条横穿村庄的小溪。村里人清晨起来的第一件事就是将家里的大水缸挑满水，以备一日之用。我们小的时候还经常在小溪里游泳。有时口渴了就着溪水猛喝一气。现在别说挑溪水做饭，就是洗菜拿回家还要用自来水再洗上一两遍。夏天看到这些脏水，我们不再有跳下去的冲动。鱼儿在水里游来游去的情景如今是看不到了。溪水中、溪边随处可见的是各种各样的垃圾，那些塑料袋有的早就变色了，但就是不肯化掉。村民习惯将所有的垃圾随手倒入溪中，他们相信溪水会带走这些他们不需要的东西。或是堆在门前的空地上，积多了便点上一把火，于是谈笑间，垃圾灰飞烟灭了。 可以预计将来村里人的生活会越来越好，钱会越来越多，楼会越来越高。人会越来越“懒”吗？但是水会越来越脏吗？村里人的这种“懒”，老一辈的人是看不惯的。不过这也正说明了生活的变好啊！得益的是家乡的后代。水的越来越脏，村里的小孩子怕也是早就习惯了吧。受害的不也是他们吗？
家乡的美食我的家乡是四川一个普普通通的小镇，它虽然毫不起眼，但是却有着自己独特的韵味。我最喜欢吃酸辣粉和麻辣烫了，将光滑、雪白的粉条倒进沸腾的开水中煮一会儿，待粉条煮熟了以后，就被倒进干净的瓷碗中，在上面撒上葱呀、蒜泥呀、胡椒粉等作料，再将鲜红的汤汁倒进半碗进去，就这样，一碗美叶的酸辣粉就做好了。麻辣烫的做法更简单，将粉红的火腿呀什么的串在干净的竹签上，放进锅里锅边用夹子把竹签夹着，防止它整个儿都进了锅里，锅内鲜红的汤汁翻滚着，汤面上密密麻麻地漂浮着花椒、辣椒，以及一些我叫不出名的作料，过了一会儿，麻辣烫煮熟了，将它从锅里捞出来就可以吃了。小孩子特别爱吃麻辣烫，不管是上学还是放学，他们都要买上一串在路上吃。大人们比起麻辣烫来，似乎更爱吃酸辣粉一些。难道不是吗？不论是下雨还是别的什么坏天气，小店里的人总是满满的。而且坐在桌旁埋头吃酸辣粉的总是大人们，在热气腾腾的锅旁等候的除了几位给孩子买麻辣烫的大人和几名中学生外，大多数是活泼的孩子。我和妈妈也很爱吃酸辣粉和麻辣烫。如果一个星期没有吃到一碗香喷喷的酸辣粉和几串美味的麻辣烫，我心里就不踏实，怪难受的。每个星期日我都会拖着妈妈一起去吃酸辣粉。也许是国为大家心灵相通吧！小店里总是挤满了人：有工人，有学生，还有教师……遇到人满的时候，我总是把嘴一噘，站在一旁，责怪妈妈误了时间。这时，和蔼可亲的老板娘总会过来打圆场：“小姑娘，别生气了，是我的错，是因为我这店太小了！”那幽默风趣的话逗得我导火线涕为笑。人少下来的时候，我和妈妈就坐在位子上，津津有味地吃着。酸辣粉的味道好极了，酸酸辣辣的，让人忍不住吃了还想吃。吃完粉后，我总会多要几串麻辣烫在回家的路上细细品尝，可最后的一串我绝对会风卷残云般地把它吃得干干净净。啊！家乡的美食！
