Abstract
The main goal of this investigation was to identify the listening strategies of Iranian male and female foreign (English) language learners and to compare the listening strategies of both groups of research participants. To investigate, 76 undergraduate students of different major of English were selected via administrating the Oxford Placement Test (OPT).Then, they were divided into two groups of 38asked to complete Cheng’ s (2002) 30-item Listening Strategyin the Likert-scale format to identify the listening strategies they use. Then the data gathered
were run through statistical tests, including descriptive test and Mann Whitney U-test. Based on the findings of the studythe listeners usedmore metacognitive strategies than cognitive and socio-affective strategies respectively.In addition, as gender influenced selecting the types of strategies for listening, it can be efficient for policy makers, syllabus designers, practitioners and instructors especially in Iran where classrooms are separated according to students’gender.
Key words:Listening Strategies, Metacognitive Strategies, Cognitive Strategies, Socio-affective Strategies

Introduction
1.0. Introduction
Listening has become an important part of manysecond or foreign language (L2)programs,as both it is a means to access various sources of knowledge and it is a criterion to determine whether an EFL learner is a competent language performancer or not. Teachers can help students improve their listening competence by equipping them with effective listening strategies and skills.In fact,its importance is influenced by the overwhelming amount of listening input in everyday life.
Despite its importance,listening is not an easy skill to master,especially listening in ESL or EFL contexts.Teachers look for the methods to find a way to enhance listening profeciency.Researchers and educaters know that learning strategies are necessary for EFL learners to be a successsful one.Many reseachers have investigated on learning strategies to find which strategieas can improve learning and especially listening skill.
Chamot (2005) believes that Learning strategies are the thoughts and actions that individuals use to accomplish a learning goal. A lot of investigations in 1970s show the importance of learning strategies. The results mention that learners’ own creative and active participation play an important role in their success in spite of having much aptitude and motivation.

Abstract
With the goal of finding an alternative to gelatin in the processing of pharmaceutical capsules, the effects of k-carrageenans on dually modified cassava starch were investigated. While film forming and mechanical properties are important in all pharmaceutical capsules, solubility at high solid concentration and thermo-reversibility are important factors for hard capsule processing. Casava starches were modified first by hydrochloric acid (0.14 N for 6, 12, 18, and 24 h at 50 °C) and secondly by propylene oxide (10, 20, and 30% of solid for 24 h at 40°C).
To improve the gel setting property of the dually modified starch, dually modified cassava starches were combined with k-carrageenan (0.25, 0.5, 0.75, and, 1%). The concentration of the K+ ion in the composite mixture was adjusted appropriately to achieve the same sol-gel transition temperature. The rheological properties of the mixtures were measured and compared, with gelatin as the reference material. The solution viscosity, sol-gel transition, and mechanical properties of the films made from the mixtures at 50 °C were comparable to those of gelatin. The viscoelastic moduli (G’ and G”) for the gel mixtures were lower than those of gelatin. The composite gels had temperatures of gelation similar to that of gelatin. Both viscosity in solution and stiffness in gels could be adjusted using high levels of κ-carrageenan and was relatively independent of the molecular weight of the starch. These results illustrate that dually modified cassava starch in combination with k-carrageenan has properties similar to those of gelatin, thus these starches can be used in dip-molding processes, such as those used to make pharmaceutical hard capsules.
Chapter 1: Introduction
1.1 Background
The capsule is one of the formulations of the oldest pharmaceutical in history, known especially from the ancient Egyptians. In Europe, it was not until the nineteenth century that the first gelatin pharmaceutical capsule with the patent of Mr. Dublanc pharmacist and his student Mr. Mothes. Over the years, this invention has been so successful that the production of capsules has grown rapidly in many countries. This has led to many improvements including the invention of hard gelatin capsules in 1846 by Mr. Lehuby (Podczeck & Jones, 2004).
The development of pharmaceutical capsules, used for therapeutic purposes, originates in the keen interest shown by the numerous researches in pharmacology. This has greatly expanded the range of possible formulations using pharmaceutical capsules. Today, pharmaceutical capsules are mainly based on animal gelatin from porcine or bovine. Gelatin is an animal protein that is a traditional ingredient in many fields, including food. Gelation properties at temperatures close to room temperature and formation of homogeneous films, potable, gelatin as a choice for the manufacturing of pharmaceutical capsules.
However, the use of animal gelatin in the food and pharmaceutical industry is governed by regulations becoming more stringent. The precautionary principal applied, for example, the risk of transmission by animal gelatin; the bovine spongiform encephalopathy (BSE) has questioned its use. Even if today the rules on the origin of the gelatin are very strict and that gelatin is no longer a risk to health, development of alternative products of interest to pharmaceutical and food industries. The sources from which gelatin can also be problematic for ethical or religious populations. Many people around the world do not consume products made from pork (vegetarians, Hebrews, and Muslims) or beef base (vegetarian Hindus). It is therefore that the replacement of gelatin with other texturing agents of non-animal origin has been much research in recent years.
The most important properties that potable gelatin as capsule forming material are heat sealability of films for soft capsule processing and solubility in high concentration, film formability and thermo-reversibility for making hard capsules.
Starch as a plant based material is one of possible alternative for gelatin due to cost and accessibility. Native starches can form films, but the films have not heat sealability, also starches are non soluble biopolymer, and form non-reversible gels. So changes or supporting the structure likely improve the starch property to consider as gelatin replacement in some cases.
The proposed system is a mixture of starch and k-carrageenan. Starch would give the mixture of film-forming properties and solubility in aqueous and carrageenan bring its ability to gel. The selected starch has focused on the use of such modification(s) on starch that able it to dissolve at temperatures below 100 °C and form stable solutions at high concentrations (≈ 20-30%). The botanical origin of the cassava starch is due to its proper amylose content, which improves mechanical properties of films and availability of this starch in Southeast Asia. The gelling agent has been studied was κ-carrageenan/K+ for its ability to form thermo reversible gels and easily adjustable thermo-physical transition temperatures. The film-forming mixtures were prepared by casting method.
The main objective of this research project is to replace the gelatin with a composite cassava (tapioca) starch film for manufacturing of pharmaceutical capsules especially hard capsules. The idea for hard capsule processing is to develop a new system whose characteristics in the solution and solid state would be closer to existing formulations. The constraints imposed industrial development concentrated formulations (25-30%) prepared at temperatures below 100 °C capable of forming a gel by physical cooling and forming a film after drying.

ژان ماری گوستاولوکلزیو از جمله رمان نویسان مشهور این قرن است . وی رمان هایی می نویسد که در آنها بیش از پیش دلزدگی خود را از جامعه مدرن بیان می کند.سبک او به نوعی خویشتن داری نزدیک می شود و مضمون ها بسیط تر می شوند.وی همچون قهرمانان داستانهایش پیوسته در سفر است اما هرجا باشد همچون شاهدی بر آدم و آدمیت است.انسان همواره ترس از گذر زمان دارد؛و در برابر آن عکس العمل ای گوناگونی برای دانستن آن از خود بروز می دهد مانند :نوستالژی، دلهره،افسوس و طغیان.این ها عکس العمل هایی هستند که در تمام انواع ادبی مانند رمان،تئاتر و… بیان می شوند.زمان نه تنها در ادبیات استوار است بلکه محوری است که در اطراف آن تصاویری که ازتخیل نویسنده ظاهر شده است ،قرار دارد.نویسنده مانند دیگر انسان ها ترس از زمان دارد اما آنچه که وی را از دیگران متمایز می سازد توانایی وی برای بیان کردن ترسهایش به وسیله ی تصاویر است.ما برای بیان این فرضیه از متد ژیلبر دوران استفاده کرده ایم تا ببینیم آیا نویسنده توانسته بر ترس خود غلبه کند یا خیر. از این رو در فصل اول به این نکته می پردازیم که آیا لوکلزیو نوعی ترس از گذر زمان را بیان کرده است؛و در فصل بعدی خواهیم دید که آیا لوکلزیو توانسته در برابر این گذر زمان پیروز شود یا خیر.از آنجائیکه لوکلزیو از جمله نویسندگانی است که جایزه نوبل را به خود اختصاص داده است و نحوه نگارشی متفاوت و کاملا نو نسبت به جهان پیرامون خود دارد.نگرشی متاثر از دو دنیای متفاوت غرب و آفریقا.در رمان های وی زبان به جای آنکه وسیله ارتباطی میان من و جهان باشد وسیله ی بیان حس هاست و دیگر قیود زمانی و مکانی را نمی توان رعایت کرد .به همین دلیل در رمان هایش می بینیم که زمان گاهی گذشته و گاهی حال است و ظاهرا هیچ دلیلی برای این جابجایی دیده نمی شود جز اینکه آیا لوکلزیو نوعی ترس از گذر زمان را بیان می کند یا می تواند در برابر این گذر زمان پیروز شود.
Introduction
J.M.G Le Clézio est un auteur de l’Afrique. Il fluctuante entre Afrique et Occident. Son histoire personnelle témoigne de l’ambiguïté de sa situation. Il va découvrir, dès l’enfance, l’Afrique et sa colonisation. Son écriture aussi fluctuante entre deux mondes. Le Clézio met en place un texte qui se cache, qui résiste. Pour lui la parole doit susciter des questions pour être efficace, elle ne doit pas être accessible immédiatement. Il ne cherche pas à produire un effet stylistique, mais plutôt à atteindre une vérité de parole. Il condamne le style qu’il considère comme un mensonge. Il vise une langue spontanée, vivante, semblable à un souffle. La parole retenue est un élément essentiel dans la poétique le clézienne. La parole conteuse crée une médiation, elle peut se faire le porte-parole d’une mémoire collective. C’est une parole vivante, le conteur doit conserver et restituer le ton de ce qui est dit. Le Clézio situe ses récits dans des lieux de culture orale comme l’Afrique.
Le désert s’impose comme le lieu de la révélation. Il est celui des origines, il s’impose comme un infini de silences. Son image, omniprésente dans l’œuvre de Le Clézio, symbolise la quête du silence, de l’origine. L’écrivain vise une langue spontanée, vivante, semblable au souffle du vent du désert. Le désert purifie par son silence. La richesse de la langue vient pour lui du métissage, qui seul permet d’entendre tout ce qu’il y a dans les mots. Il cherche à retrouver cette parole vive dans sa propre écriture. Par les langues étrangères, Le Clézio dévoile le secret du langage, son écriture requiert la participation du lecteur qui doit écouter le texte et non plus seulement le lire. Il y a ainsi dans l’écriture le clézienne une forte dimension sociale et idéologique. Le Clézio s’adresse au public occidental, sa fonction de dénonciation revêt alors toute son importance. L’écriture est, pour lui, un de ses seuls moyens d’action, « Je ne suis qu’un écrivain, alors que faire ? J’écris ». L’écriture de l’Afrique est pour lui un mode de dénonciation de l’Occident. Sa mise en scène des cultures orales est à envisager comme un effet de miroir inversé des cultures dominantes de l’écrit. L’écriture des cultures orales est ainsi, pour Le Clézio, le mode d’un retour à l’imaginaire, aux sources de son écriture.
Le Clézio dans ses œuvres essaie de découvrir ce côté inconnu de la vie où il est possible de trouver le salut, où le regard s’affole de tant voir, où l’ouïe perçoit les bruits les plus ténus; où les mots sont inutiles et où les gestes uniquement comptent. Il poursuive une quête, de rechercher un même vrai sens à la vie, une qualité essentielle, celle du regard, un regard libérateur, nu, sans aucun préjugé; un regard que le merveilleux enseigne bien plus que la réalité scientifique.
La conscience du temps est donc présente dans l’œuvre de Le Clézio. Le temps paraissait immense, très lent, avec par instants de drôles d’accélérations incompréhensibles, des vertiges, comme si on traversait le courant d’un fleuve. Le temps apparait pour l’homme, comme une réalité négative en lui-même, pour autant qu’il soit lié au devenir, à la douleur de l’existence et à la mort.
« Depuis toujours, le temps a été source de l’angoisse, parce qu’il est synonyme de la mort. En effet, il ne cesse pas de s’écouler et conduite l’homme vers la fin de son voyage terrestre, passage obligé de la condition humaine. L’homme s’est toujours confronté à la mort. Il faut dire que l’homme est temporel : le temps apparaît comme inséparable de la condition humaine. Il domine la vie de sa présence, il impose ses effets. »1
Le temps va alors exercer une puissance influence sur l’imagination de Le Clézio. Son omniprésence annonce qu’il occupe une place essentielle dans l’œuvre de Le Clézio. Nous voulons préparer une étude des figures du temps chez Le Clézio.
Dans cette partie, comme l’instrument de recherche, nous voulons présenter la méthode critique de Gilbert Durand. Cependant, il faut signaler que notre travail n’envisage pas une étude totale du système durandien. Elle est une petite introduction à une grande recherche appliquant cette méthode. Notre étude, fondée sur la notion de la critique, n’est qu’un travail élémentaire pour la compréhension d’une pensée.
La base et le principe de la pensée durandienne sont profondément liés aux théories de l’épistémologue et critique Gaston Bachelard.
[1] ABBASSI, Ali, La Peur du Temps chez Hugo, Université SHAHID BEHESHTI, 2004, p. 2.
Le dernier insiste sur le rôle important de la rêverie et de l’imagination dans la création des œuvres littéraires. En effet, Bachelard et Durand ont toujours eu un regard particulier sur l’image. D’après eux, les images poétiques ont un système qui est définit par l’imaginaire. Ce dernier se base sur les images originelles sans lesquelles les manifestations de la vie et des valeurs vitales seraient impossible. Ces images sont celles qui sont inspirées par les matières fondamentales, par les mouvements principaux, comme monter et descendre, et par les quatre éléments fondamentaux : feu, eau, terre, air.
Dans son ouvrage : Les Structures anthropologiques de l’imaginaire. Introduction à l’archétypologie générale, paru pour la première fois en 1960, Gilbert Durand présente sa démarche. L’ouvrage a pour objet de définir le sémantisme primitif des images et d’établir une ” classification des grands symboles de l’imagination “. Il établit que les produits de l’imagination ont une signification intrinsèque, qui détermine notre représentation du monde. Il définit l’imagination comme « la racine de toute pensée. »1
[1] CHELEBOURG, Christian, L’imaginaire littéraire, Des archétypes à la poétique du sujet, Paris, Nathan, 2000, p. 57.
Les réalités géographiques et cosmiques, les structures sociales, la conscience de la fécondité féminine, de la force virile, toutes ces données objectives de la perception se mêlent à nos pulsions profondes pour constituer notre représentation du monde. Entre ces deux dimensions de la réalité, l’une objective, l’autre subjective, l’imagination opère un perpétuel va-et-vient, un échange constant, auquel Gilbert Durand donne le nom de “trajet anthropologique.” Ce trajet définit l’imaginaire :
« Finalement, l’imaginaire n’est rien d’autre que ce trajet dans lequel la représentation de l’objet se laisse assimiler et modeler par les impératifs pulsionnels du sujet, et dans lequel réciproquement, comme l’a magistralement montré Piaget, les représentations subjectives s’expliquent « par les accommodations antérieures du sujet » au milieu objectif.»1
D’après Durand, toutes pensée repose sur des images, qui n’ont rien à voir ni avec la mémoire, ni aves la perception.
1 DURAND, Gilbert, Les Structures anthropologiques de l’imaginaire, Introduction à l’archétypologie générale, Paris, Dunod, 1992, p.38.
En effet, la conception de l’anthropologie de l’imaginaire que Gilbert Durand a construit s’est fait sur cette constatation qu’à l’origine de toute culture, il y a une peur essentielle qui est la peur de la fuite du temps. Ce que Durand appelle le Chronos dévorant, que toutes les productions, pratiquement imaginaires et intellectuelles peuvent relever des réponses à cette fuite du temps.
En réalité, le principe classification de Durand est la bipartition des symboles entre deux grands régimes : “diurne et nocturne”. Ces régimes représentent deux manières de lutter contre le temps et l’angoisse de mort. Fondamentalement antithétique, le régime diurne oppose deux grandes catégories d’images, les unes qui signifient l’angoisse devant le temps, les autres la volonté de vaincre celle-ci et de s’élever au-dessus de la condition humaine. Parmi les premières, on distingue trois types de symboles représentant les visages du temps. D’abord des symboles thériomorphes, des images animales qui signifient soit l’agitation et le changement, soit l’agressivité et la cruauté. Ensuite viennent des symboles nyctomorphes, des images de la nuit qui transposent en terme d’obscurité la craint engendrée par le temps. Il groupe les images de l’impureté, de l’eau noire, mais aussi celle de l’aveuglement. Enfin, des symboles catamorphes, des images de la chute, mais aussi des images du sang, du vertige, de la pesanteur ou de l’écrasement. Ces symboles disent la déchéance de l’homme, chassé du paradis et devenu mortel.
À toutes ces images des temps, valorisés négativement, s’oppose le symbolisme symétrique de la victoire sur le destin et sur la mort. Il constitue le deuxième type d’images du régime diurne. À l’intérieure de celui-ci, Gilbert Durand distingue de nouveau trois catégories de symboles. En premier lieu, des symboles ascensionnels, par lesquels l’homme atteint à une souveraineté céleste, on trouve ici les images de l’élévation, de l’aile, de l’ange, du géant. Puis, des symboles spectaculaires, ils groupent les symboles de la lumière et les organes de la lumière : le soleil, l’œil, le verbe divin. Pour finir, des symboles diaïrétique, symboles de la puissance et de pureté qui se composent des armes et des insignes de la victoire, de l’accession à la transcendance : flèche, glaive, etc.
Les structures mystiques et synthétiques constituent le régime nocturne. Le premier cherche à nier le temps sur le mode de l’antiphrase, et le deuxième à s’en accommoder, à tirer parti de sa nature cyclique.
Dans les structures mystiques les symboles ne font plus vivre le monde en termes de conflit, comme dans l’antithèse, mais visent, au contraire, à réduire ses dangers, à les euphémiser au point de les nier, de les inverser, comme par antiphrase. Ils se répartissent en deux groupes : un groupe d’images de l’inversion et un groupe d’images de l’intimité. Ces structures de mystiques conjuguent une volonté d’union avec le monde et le goût de l’intimité secrète. Elles reçoivent également l’épithète d’antiphrasiques, pour souligner que leur fonctionnement générale est celui de l’antiphrase.
Dans les structures synthétiques ou (dramatiques) les symboles sont tous cycliques, ils sont animés par le désire de maîtriser le temps en utilisant ses rythmes propres. Pour y parvenir, ils s’orientent soit dans le sens de l’eternel retour, soit dans celui du progrès. Les cycles de l’éternel retour comportent une phase négative et une phase positive, la première étant interprétée comme nécessaire à l’avènement de la seconde, ce qui en euphémise la
négativité. Dans les symboles progressistes, le dernier cycle « n’est qu’un cycle tronqué ou mieux une phase cyclique ultime emboîtant tous les autres cycles comme figures et ébauches de l’ultime procès. »1 Les symboles cycliques se présentent sous la forme de récits dramatiques, de mythes opérant la synthèse, la réconciliation si l’on préfère, d’images qui s’opposent dans les autres structures de l’imaginaire. Les modèles naturels de ces cycles sont les phrases de la lune et le cycle végétal des saisons.
Puisqu’ un travail constituant tous les deux régimes deviendra trop long pour un mémoire de maîtrise, notre travail se contente d’étudier les images du régime diurne de l’imaginaire.
[1] Ibid., p. 322.
Temps est un thème fréquent chez Le Clézio, Pour étudier ce concept chez Le Clézio, nous essaierons de voir, d’une part, si il prouve une certaine peur face à la fuite du temps ? Si oui, pourquoi ? D’une autre part, est- ce qu’il pourrait maîtriser la fuite du temps ? Si oui, comment ?
En tant que corpus, face à une immense production littéraire, il est à signaler que nous avons étudié une petite partie de l’œuvre romanesque de Le Clézio pour analyser des figures de l’imaginaire. Nous avons travaillé sur les ouvrages : La Ritournelle de la faim, Désert et L’Africain.
Ce travail comprend deux parties. Dans la première partie nous allons étudier les images négatives du régime diurne regroupées autour des symboles thériomorphes, nyctomorphes et enfin catamorphes. Et dans la partie suivante, nous allons voir si Le Clézio pourrait enfin montrer une victoire face à l’écoulement du temps. La réponse à cette question sera une analyse des images positives du régime diurne regroupées autour des symboles ascensionnels, spectaculaires et enfin les symboles de protection contre le temps.
I. LA FUITE DU TEMPS
I.I LES SYMBOLES THÉRIOMORPHES
Dans ce chapitre consacré aux symboles thériomorphes, nous allons présenter comment la bestialité se manifeste dans l’imaginaire de l’auteur. Dans l’imagination de Le Clézio, la peur, l’angoisse devant le temps et devant la mort se révèlent sous forme d’animal terrifiant.
Cette partie va montrer l’importance de l’archétype d’animal dans l’imagination de l’auteur. Nous considérons les images animalisées du soleil, de la lune, de l’air et du sel qui constituent les images chaotiques chez Le Clézio.

Abstract
Repression, beating and abusing of women and regarding them as the “second sex” are issues that cannot be ignored. These affairs are also shown in vast dimension in post-modern American literature in which women characters are in search of “identity” and a way of liberty and freedom from patriarchal society to heal themselves but all their efforts lead to a life of “ambiguity” and nothing more; alike what women do and live in the real world. The question that comes to mind is that “what is the reason and what if there can be a solution?” This research is planned to have a feminist point of view on female characters of the three plays of Sam Shepard Buried Child, A Lie of the Mind and States of Shock. Due to the broad spectrum of the history of feminism, the methodology of this study focuses on Irigaray, a contemporary French feminist, theorist, psychoanalyst and critic of literature, through her ideas of “subjectivity”, “sexuality”, “language” and “desire”; And Helene Cixous Another French feminist and philosopher whose challenging theory of “Feminine Writing” are surveyed through this study. In the process of this research it is revealed that the belief in the theory of “transition of woman’s personality” is shared among all three thinkers and is experienced by women’s of Shepard’s plays in three social situational phases of “normal”, “sick” and “crisis”. However, the post-modern viewpoint of Shepard, Irigaray and Cixous, conveys that women fail in this transition and cannot achieve their “ego” in the modern era and their ambiguity remains with them. Finally the research concludes that literary writing and expression of problems are the part of solution which post-modernists show by criticizing “modernity”.
Keywords: transition, identity, subjectivity, literary therapy, Shepard, Cixous, Irigaray.

1.1 General Background
Sam Shepard (5 November 1943- ) is “the greatest American playwright of his generation” (New York Magazine). In his high school years he began acting and writing poetry. In 1963, he moved to New York City where he met Charlie Mingus who introduced him to a jazz group. In these years he became familiar with Cinema too, he was especially interested in Western movies, which had a great impact on his personality.
His father’s personality and his life that is full of immigrations are the factors, which influenced his works. He loved his father so much and had a very friendly relationship with him and maybe the reason for such a relationship is the several travels, which he had with his father.
In the sixties, American art was undergoing some basic changes, which were related to autonomy of art and literature from their old traditions; Shepard was also under the influences of these changes. In this period Broadway theatre was put aside and a new theatre was created with the aim of reconstructing society.
It was in 1960 that he began his work as a postmodernist in American theatres. Many critics believe that Sam Shepard is the most enjoyable and excitable contemporary playwright in America, but little can be said about what exactly makes his plays interesting and exciting.
Shepard deliberately focuses on the issue of family and in this way he somehow psychoanalyzes the system of family in America. He believes that the reason of his emphasis on family issue is that 1960s was a period of family crisis in America and he himself was greatly affected by this crisis. He was raised up in an environment where “men” had the superior and dominant role and “Alcohol” and “violence” were the main threats for Family’s foundation. He clearly stated that the biologic and blood relations between brothers and sisters in a family were always interesting for him (Callens 27-39) which can be seen in Buried Child and A Lie of the Mind.
Shepard, who was grown up in a patriarchal family, was always curious and interested in woman’s personality: therefore when he brings a female character in his plays he is actually showing us the unconscious part of his mind. For this reason in the process of writing he does not usually hesitate and he writes spontaneously. He said that he completely wrote “Buried Child” in a spontaneous mode.
It can be concluded that he portrays women’s characters through his psychological vision and intuition. In this regard he says:
I don’t know that much about my woman’s characters evolutions or their maturity but I think that they gradually become active and strong characters and they are not merely a symbol of something, in my early works they were more of a sign or symbol […] and I think the evolutions and changes of my woman’ characters started with “Curse of the Starving Class” in characters of mother and daughter and then it continued in “Buried Child” and “A Lie of the Mind” (Shepard 25)
انگیزش یکی از عوامل کلیدی است که تعیین کنندهی موفقیت یا شکست زبانآموزان در محیطهای EFLیا ESL میباشد. بنابراین مسئولیت سنگینی بر دوش پژوهشگرهای حوزهی انگیزش قرار دارد تا معلمان را در جهت ایجاد انگیزش در زبانآموزان، بالا بردن، و حفظ آن یاری کنند. تحقیق دورنیه و سیزر (1998) در کشور مجارستان اولین مطالعهی مهم روی راهبردهای انگیزشی بود. بعد از آنها مطالعات اندکی در این حوزه انجام شد. در این تحقیق 250 نفر معلم ایرانی شرکت کردهاند و از آنها خواسته شده است که دو نوع پرسشنامه شامل 48 راهبرد انگیزشی را به این شرح کامل کنند: (1) نگرش آنها دربارهی میزان اهمیت راهبردهای انگیزشی (پرسشنا مهی میزان اهمیت) و (2) نگرش آنها دربارهی میزان استفاده از راهبردهای انگیزشی در کلاس درس (پرسشنامه ی میزان استفاده)، در ضمن نسخهی فارسی پرسشنامهها به معلمان تحویل داده شده است. نتایج بدست آمده از تحلیل آماری پرسشنامهها مشخص کرد که : راهبردهای انگیزشی ” نمایش رفتار مناسب از طرف معلمان” و “ آشنا کردن زبان آموزان با ارزشهای مربوط به زبان انگلیسی” در هر دو پرسشنامه به ترتیب در رتبههای اول و دهم ( آخرین رتبه ) قرار گرفتهاند. در میان 10 ماکرو راهبرد انگیزشی استخراج شده از هر دو پرسشنامه، راهبردهای اشاره شده در بالا وابسته به فرهنگ خاصی نیستند و در اکثر فرهنگهای کشورهای مختلف به میزان مشابهی قابل رویت هستند، ولی تکنیکهای انگیزشی از قبیل: “بوجود آوردن محیطی شاداب در کلاس درس” به نظر میرسد وابسته به فرهنگ خاص کشورها هستند و میزان اهمیت و کاربرد آنها برای فرهنگهای کشور های مختلف، متفاوت است. علاوه بر این، مقایسهی نتایج پرسشنامههای “میزان اهمیت” و “میزان استفاده” مشخص کرد که نگرش معلمان نسبت به اهمیت راهبردهای انگیزشی هیچ رابطهای با نگرش آنها نسبت به میزان کاربرد واقعی این راهبردها در کلاس درس ندارد.
Abstract
Motivation is one of the key factors that determine language learners’ success/ failure in ESL/EFL situation. Thus, it is a major challenge for language motivation researchers to help teachers elicit, enhance, and sustain students’ motivation. Dörnyei and Csizér’s (1998) research in Hungary was the first important study on motivational strategies. Following Dörnyei and Csizér (1998), a few similar studies have been carried out in this realm. 250 Iranian EFL teachers participated in this study and they were asked to rate a list of comprehensive 48 motivational strategies in terms of (1) how much importance, Importance Questionnaire, they attached to these and (2) how often, Frequency Questionnaire, they implemented them in their real teaching practice. The Persian version of the questionnaires was used in this study. The results provide evidence that some strategies like “displaying appropriate teacher behaviors” and “familiarising learners with L2-related values” were ranked first and tenth respectively in both questionnaires. Among ten macro-strategies derived from both questionnaires, some scales like two aforementioned ones are culture specific and can transfer across cultures but some other scales like “Creating a pleasant classroom climate” are culture dependent and vary from culture to culture. Also, comparing the results of two questionnaires revealed that teachers’ attitudes to the Importance of motivational strategies have no relationship with their answers to their actual Frequency of use in real EFL classes.

CHAPTER ONE- INTRODUCTION
1.1. Overview
In the field of second or foreign language (L2) teaching and learning, motivation is a significant factor that leads to the language learners’ success or failure. Motivation is the most used concept for explaining the failure or success of a learner. Dörnyei (1998) claimed that motivation is a key to learning. It is an inner source, desire, emotion, reason, need, impulse or purpose that moves a person to a particular action. Motivation has been regarded as one of the main factors that influence the speed and amount of success of foreign language learners. This issue seems to be highly related to the educational context of Iran where it is seen that many Iranian learners of English as a Foreign Language (EFL) fail to reach at least an average level of proficiency in English. As Dörnyei (2001b) claims, motivation is not a concrete concept; it is an abstract and hypothetical concept that is used to explain why people think and behave in certain situations as they do.
Students’ lack of motivation in language leaning contexts is a major problem for language teachers. According to Dörnyei (as cited in Marie-Jose´ Guilloteaux, 2013), a lot of researchers have tried to help teachers find ways of motivating language learners. In spite of the studies which have been done in this regard, the cultural and ethno-linguistic differences in various contexts were one of the important motives of doing this research.
Accordingly, the aim of this research is to evaluate (a) the extent to which a list of motivational strategies derived from Western educational contexts are perceived as relevant by Iranian EFL teachers and (b) the cross-cultural validity of those motivational strategies. To this effect, the present study builds on Dörnyei and Csizér ’s (1998) initial investigation in Hungary and on its modified replication conducted in Taiwan(Cheng and Dörnyei, 2007) and strives to find out how the same concept functions in Iran.
1.2. Statement of the Problem
Regarding the complex nature of motivation and its remarkable influence in second and foreign (L2) language learning, there are a growing number of studies focusing on motivation and motivational strategies in language teaching and learning settings. Dörnyei (as cited in Marie-Jose´ Guilloteaux, 2013) believes that until the early 1990s, most of the researchers studied motivation from a social psychological perspective. Much of the research in this period has been initiated and inspired by two Canadian psychologists, Robert Gardner and Wallace Lambert, who, together with their colleagues and students, grounded motivation research in a social psychological framework. Gardner and his associates also established scientific research procedures and introduced standardized assessment techniques and instruments, thus setting high research standards and bringing L2 motivation research to development (Ellis, 2008). Although Gardner’s motivation construct did not go unchallenged over the years, it was not until the early 1990s that a marked shift in thought appeared in papers on L2 motivation as researchers tried to reopen the research agenda in order to shed new light on the subject. The main problem with Gardner’s social psychological approach appeared to be, ironically, that it was too influential. While acknowledging unanimously the fundamental importance of the Gardnerian social psychological model, researchers were also calling for a more pragmatic, education-centered approach to motivation research, which would be consistent with the perceptions of practicing teachers and which would also be in line with the current results of mainstream educational psychological research. It must be noted that Gardner’s motivation theory does include an educational dimension and that the motivation test he and his associates developed, the Attitude/Motivation Test Battery (AMTB), contains several items focusing on the learner’s evaluation of the classroom learning situation. However, the main emphasis in Gardner’s model and the way it has been typically understood is on general motivational components grounded in the social milieu rather than in the foreign language classroom. For example, the AMTB contains a section in which students’ attitudes toward the language teacher and the course are tested. This may be appropriate for measurement purposes, but the data from this section does not provide a detailed enough description of the
classroom dimension to be helpful in generating practical guidelines. Finally, Gardner’s motivation construct does not include details on cognitive aspects of motivation to learn, whereas this is the direction in which educational psychological research on motivation has been moving during the last fifteen years.
Gardner’s social psychological approach has never clearly approached the classroom implications of motivation theory and it did not help language teachers in promoting their teaching practice. However around the 1990s, second and foreign language motivation research has seen an explosion of interest and the researchers have studied motivation from a more education-based perspective. In this period the authors’ attention were shifted to cognitive-situated view of motivation and situation-specific factors like learning and teaching situation were given more attention (Ellis, 2008). Authors like Dörnyei (2001a) gave prominence to more process-oriented view of motivation with an emphasis on dynamic nature of motivation and its temporal variation. Recently, some nearly similar studies on motivational strategies have been carried out by some authors like Dörnyei and Csizér ’s (1998) in Hungary, Cheng and Dörnyei (2007) in Taiwan, Hsu (2008) in Taiwan, Kassing (2011) in Indonesia, Gilloteaux and Dörnyei (2010) in South Korea, and Alrabai (2011) in Saudi-Arabia. Thus, the similarities and differences in the use of motivational strategies by English teachers in different educational contexts have been identified. Similar to the aforementioned studies, in the present study, it has been attempted to identify the top 10 strategies that Iranian EFL teachers perceive as the most important for promoting students’ L2 motivation in the language classroom. By comparing the results of this study with others conducted in different educational setting in different countries, we can recognize the motivational strategies which are culture dependent or vise-versa. In addition, we want to design practical techniques for educators and teachers of English in Iran that can be used to effectively implement motivational strategies in the L2 classroom. And again this study wants to identify the proportion with which Iranian English teachers perceive the list of motivational strategies important for language classes or the proportion with which they use these strategies in their actual language teaching situations. By making a complete list of motivational strategies that are more useful and practical in EFL context of Iran, the English teachers can make use of them for finding ways of eliciting, enhancing, and sustaining students’ motivation.
As mentioned earlier, Dörnyei and Cheng (2007) carried out a research to identify the use of motivational strategies among Taiwanese English teachers. They explored the frequency and the importance of the strategies used by Taiwanese English teachers. They compared these results with the findings of the nearly identical study conducted by Dörnyei and Csizér (1998) in Hungry. Similar to the aforementioned studies in Hungary and Taiwan, the current study is based on Dörnyei’s (2001b) framework of motivational teaching practice in the L2 classroom, which was based on the process-oriented model by Dörnyei and Otto (1998). Therefore, the frequency and the importance of the use of motivational strategies among Iranian EFL teachers will be studied to reveal the similarities and differences between Iranian teachers’ ratings of motivational scales and the other countries’. Whether unique cultures of different countries can influence the teachers’ ratings or strategy use or not? Which strategies are culture-specific or culture-dependent?
