Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

a. Contribution de l'activité au référentiel AA (AA du programme) This course contribues to the learning outcomes AA 1 (Maîtriser un corpus de « savoirs scientifiques » ; en particulier 1.1 à 1.4), 2 (Maîtriser un socle de « savoirs en ingénierie et en gestion » ; en particulier 2.1) et 4 (Concevoir et mettre en 'uvre une démarche complète et innovante d'ingénieur ; en particulier 4.1) du programme BIRF. b. Formulation spécifique pour cette activité des AA du programme (maximum 10) At the end of this course, the student is able to: - identify temperate and tropical ligneous species on the basis of anatomical features observable on small samples and microscopic sections, anatomical elements introduced in the course and illustrated during the practical exercises in laboratory ; - explain and compare wood behavior, on the basis of wood chemistry, wood properties (physical, mechanical'), (ultra)structure of the cell wall, in order to optimally valorize this material in the wood processing industry; - identify and explain the influence of growth conditions (silviculture, environment') on wood quality, by integrating the theoretical underlying concepts, in order to adopt a Bioengineer approach aware of the impacts of management on wood quality. |

Teaching methods
The course is a lecture, with small learning activities (guided questions, quiz) and concrete examples. Depending of wood news and opportunity, invited lecturers may be invited on specific subjects. The practical exercises are organised so as to allow students to integrate and apply progressively the theoretical knowledge.
Evaluation methods
Examination relies on « definition type » questions, or questions centered on a theoretical development, specific or transverse. Indeed, the ability to link concepts from different chapters is one of the learning outcomes. An separated exam, which counts for 1/3 of the rating, assess the students ability to identify a ligneous species from its wood.
Other information
This course can be given in English.
