Au 21ème siècle, communiquer en langues étrangères est désormais un facteur-clé dans un contexte mondialisé. C’est pourquoi, nous consacrons cette recherche à évaluer la compétence orale des apprenants saoudiens. Dans un premier temps, nous étudions les différentes dimensions de la compétence orale tout en mettant l’accent sur les méthodologies visant à développer la compétence orale. De même, nous analysons l’évaluation qui constitue un processus important dans un cours de FLE. Dans le cadre de cette thèse, nous analysons la production orale des apprenants saoudiens qui ont participé à plusieurs situations de communication. Cette analyse concerne, d’une part, la capacité des apprenants de communiquer oralement dans les différentes situations de communication. D’autre part, nous étudions leurs difficultés rencontrées aux niveaux lexicales, grammaticales et phonétiques. Pour aller plus loin dans notre recherche, nous avons recours aux Technologies de l’Information et de la Communication (TIC) en élaborant une formation de FLE à distance. Celle-ci a aidé, malgré certains obstacles, à améliorer la compétence orale chez les apprenants saoudiens. / In the 21st century, communicating in foreign languages has become a key factor in a global context. Therefore, this research is dedicated to assess the oral skills of Saudi learners. First of all, the research studies the various dimensions of the oral skills while focusing on the methodologies of developing those skills. It analyses as well the assessment that constitutes an important process in an FFL course. As part of this thesis, we’ve conducted a study analyzing the oral performance of some Saudi learners who took part in several communication situations. On one hand, this study analyses the ability of learners to communicate orally in various situations of communication. On the other hand, it studies the difficulties encountered at the lexical, grammatical and phonetic levels. To go further in our research, we’ve used the Information and Communication Technologies (ICT) in developing an FFL distance training, which helped, despite some obstacles, improving oral skills of Saudis learners.

This diploma thesis deals with rainwater harvesting system in the company premises and the design of plumbing system in the newly built training center and storage hall. The new standard EN 16941-1 is described in the teoretical part. This standard deals with the use of rainwater. The experimental part solves the measurement of the non-potable water in this area. In the practical part, the acquired information is applied to the newly built object in the company premises. A project is created in the form of a technical report and drawing documentation for the use of rainwater and plumbing system.
