Cette thèse vise à analyser l’interaction des procédés d’enseignement et d’appropriation dans un univers didactique multipolaire [le tuteur, les aides en ligne, les conduites d’auto-apprentissage, etc.], afin de déterminer à quelles conditions l’utilisation d’un environnement mixte rend possible la mise en oeuvre d’expériences d’apprentissage potentiellement favorables à l’acquisition de l’anglais langue étrangère auprès d’un public LANSAD en milieu universitaire. L’ouverture de cette thèse est consacrée à l’apprenant. Etant donné que la mise en place d’un dispositif pédagogique donné revient à mettre à la disposition de ce dernier des outils visant potentiellement à le conduire vers une progression qualitative et quantitative en L-C 2, celui-ci y occupe une place centrale en tant qu’utilisateur. La deuxième partie vise à mettre en évidence comment les logiques de la DLC et de la RAL peuvent être conciliées pour transformer les diverses implications et pédagogiques tirées de la première partie en outils didactiques susceptibles d’influer positivement sur les mécanismes acquisitionnels des apprenants. Ces considérations sont réinvesties dans le cadre de la troisième partie, afin d’étudier à quelle[s] condition[s] un dispositif permettant a priori aux apprenants [ou d’élaborer à leur intention] des tâches [macrotâches] qui répliquent ou simulent les pratiques sociales observées et qui servent d’objectifs aux apprenants ou à l’institution [Demaizière et Narcy-Combes, 2005] peut être mis en place. Enfin, les pratiques apprenantes au sein du dispositif élaboré sont analysées à la lumière des conclusions tirées dans nos trois premières parties. / The perspective of this dissertation is to analyze how the teaching and learning processes are interacting in a multipolar environment [tutor, online help, learning strategies] in order to shed light on the conditions to which a numerical environment is liable to promote English as a foreign language and culture [hereinafter L-C 2] acquisition amongst ESP learners at university level. The first part of the dissertation deals with the learner. If the implementation of a pedagogical environment aims at providing him - her with tools enabling both a potential qualitative and quantitative progression in L-C 2, the learner indeed plays a central role within it, as a user. In order to achieve this objective, a reflection on the L-C 2 learning processes is necessary to take them into account, as far as possible, in the setting up of a pedagogical environment. The second part looks at how the considerations of SLA, second language learning and teaching and the pedagogical implications drawn from the first part can be linked up and turned into tailor-made tools liable to impact positively on the learners’ SLA processes. The third part is about pedagogical engineering with a particular emphasis on how both the pedagogical implications drawn from the first two parts and the various parameters inherent to a pedagogical setting can be taken into account to implement an L-C 2 blended learning environment. Eventually, action research is presented. This part aims at providing an analysis of the learning practices and of the multipolar interaction taking place within a blended environment and at assessing its potential in terms of SLA.

This essay focuses on what impact developmental dyslexia has on assessment and grading in the second language teaching of English in the Swedish educational system. The data presented in this essay are based on six semi-structured interviews with English language teachers of lower and upper secondary schools from the south-eastern parts of Sweden. The interviews were conducted in Swedish, and the collected data have been translated into English. The inquiries of the interviews focused on the teachers' awareness of dyslexia and its impact on learning and teaching, as well as how they worked with and their considerations made when assessing and grading dyslexic pupils. The interviews specifically enquired what particular challenges arose in the assessment and grading process, what provided aid, and what could be done to provide further relief during this process. The results show that the assessment and grading of dyslexic pupils is similar to the general practice. The teachers do, however, accommodate the dyslexic pupils' needs in the teaching and carefully consider their difficulties when assessing and grading. The teachers use, for example, spelling programs and such technical aids to help them, to some extent, disregard dyslexic difficulties while assessing. However, results show how the teachers are not able to transfer their awareness of dyslexia and its implications into the assessment and grading situation, suggesting that the teachers' own ability to assess dyslexic pupils is somewhat inadequate.
