Appropriation de la compétence écrite de jeunes adultes malaisiens en milieu exolingue et endolingue pour une meilleure intégration dans un établissement supérieur français : problématique de l'écrit dans une situation d'apprentissage du FLE, difficultés liées à la reprise anaphorique et la reformulation de textes / The mastering of the written competency of young Malaysian adult learners of a target language in the ext-lingual and en train-lingual context with the aim of a better integration into a higher French institution of learning : issue of writing within

Ho, Lai Wan 07 December 2018 (has links)
Cette recherche vise à étudier deux procédés textuels : la reprise anaphorique et la reformulation textuelle, dans des écrits en FLE, produits par des étudiants Malaisiens à l'Institut de formation des formateurs de langues étrangères ou connu comme IPG KBA à Kuala Lumpur, Malaisie. La problématique générale s'inscrit dans le cadre de la didactique du texte écrit, relevant d'une linguistique textuelle qui permet de mieux comprendre la qualité du texte. Il s‟agit à la fois des caractéristiques observables à la surface du texte et des choix opérés pour construire et organiser la matière textuelle. La question fondamentale que nous nous sommes posée est de savoir comment aider les apprenants en FLE à se rendre compte de l'importance de l'articulation des deux niveaux local et global de l'organisation du texte, de sorte qu'ils arrivent à comprendre où se situent les dysfonctionnements dans leurs textes, de quels types de dysfonctionnements il s‟agit et de quelle manière ils peuvent y remédier. La méthodologie de recherche est basée sur une expérimentation auprès du public visé, conjuguant de facteurs textuels et extratextuels. L'analyse des textes d'apprenants a pour objectif de repérer, classer et interpréter les difficultés non seulement en fonction d'un cadre théorique d'analyse de textes mais en fonction d'une démarche comparative entre écrits d'un public en milieu d'apprentissage exolingue et celui d'endolingue. Les résultats atteints montrent que la sensibilisation des apprenants et le travail de réflexion avec eux, sur desf acteurs extratextuels, peuvent les aider à améliorer la qualité de leur production écrite. Il est aussi démontré qu‟en matière de connaissances textuelles, tout ce qui est intériorisé et maîtrisé en langue maternelle (langue première) et en anglais pourrait être exploitable de façon positive en français. Mais le français et l'anglais, deux langues étrangères, ne peuvent pas non plus être mises sur pied d'égalité, en ce qui concerne les difficultés rencontrées par les apprenants Malaisiens, du simple fait de leur « étrangeté ». Les propositions didactiques que nous avons suggérées s'inspirent de notre méthode d'analyse et reposent sur le souci d'améliorer la qualité de la production écrite en français chez le public allophone Malaisien. / This research aims at the study of two textual procedures notably the anaphoric rephrasing and the textual reformulation in the written texts in French as a Foreign Language, produced by the Malaysian students in the Institute of Teacher Training, International Languages Campus, Kuala Lumpur. The overall issue is embedded in the framework of the teaching of writing within the domain of textural linguistics. The latter enables us to understand better the quality of the text. This study deals with the observation of characteristics at the surface level as well as the choice of operations to construct and organise the textual matter. The fundamental question which confonts us is to know how to help foreign learners in French to be conscious of the importance of the global and local articulation of organising a text, leading to a better comprehension of where the textual defauts are situated. It's also more crucial to identify the types of defauts or textural disfonctionnings concerned and the remedial methods to these problems. The research methodology is based on an experiment conducted on a group of learners targetted, on a topic governed by the textual and extratextual factors. Analysis of the learners' written productions is for the objective of retrieving, regrouping and interpreting the difficulties from not only the theorical point of view but also responding to a comparative study between the written productions of a public in an exolingual and endolingual learning situations. The results achieved show that the consequences of writing on a topic bound byt he extratextual factors on the learners and the post-period of reflexion with them could help them in improving the quality of their written production. It attested also that the textual content knowledge and all that is interiorised and acquired in the first language as well as in English could be exploited in a positive way in French. However, French and English, two foreign languages cannot be put a long side equally when it comes to difficulties confronting the Malaysian learners, from the simple factual reason of their « alienicity ». The didactic propositions, which are suggested, are inspired by our method of analysis with the sole aim of improving the quality of written production in French among the Malaysian foreign learners of French.

An Investigation of Methods to Homogeneously Entrain and Suspend Abrasive Particles in a Low Pressure Dental Water Jet

Grygla, Michael Sean 19 January 2007 (has links) (PDF)
During the past several decades, the water jet cutting concept has developed from a novel concept into a well-accepted machine cutting tool. With the addition of abrasive particles and the improvement of high pressure pumps, the water jet stream is currently capable of cutting through metal, concrete, and composite materials. Water jet systems have been utilized at a wide range of different pressures. Research performed at Brigham Young University has revealed that low pressure water jets have the ability to cut human teeth. Experiments have shown that when abrasive particles are added to the water jet stream, an greater amount of tooth material can be removed at lower input pressures. Many different methods have been proposed to entrain and suspend particles in a high pressure water jet system. The abrasive particles can be entrained before the water is pressurized, while the water is being pressurized, or after the water jets stream exits the pressurized system. Each method has its advantages and disadvantages. Unfortunately, keeping abrasive particles homogeneously entrained and suspended in a water jet stream has proven to be difficult. Research at Brigham Young University has encountered similar problems. Researchers are attemping to place abrasive particles in a low pressure water jet stream, but have not been able to maintain a suspended homogeneous slurry. It is the objective of this research to investigate and suggest several possible methods to entrain and suspend abrasive particles into a low pressure water jet system intended for a dental cutting application. A broad review of methods to entrain abrasives in high pressure water jet systems was performed. A list of methods and concepts as possible solutions to entrain abrasives in a low pressure system has been generated. Product design principles were applied to screen, score, and rank these generated concepts to narrow down the list to the most viable concepts for BYU's low pressure dental water jet. Several tests and experiments were also performed to validate the suggested concepts and to provide useful information for future research. It is anticpated that one or more of these methods will be applicable for the proposed dental application as well as other similar applications.
