Teaching methods

Classroom lectures, seminars.

Assessment methods

The exam consists in an written test and/or oral interview in order to assess the methodological and critical skills acquired by the student. The student will be invited to discuss the topics covered during the lessons.

The achievement of an organic vision of the issues addressed during the classes and their critical use, which demonstrate ownership of a mastery of expression and specific language, will be assessed with marks of excellence. Mechanical and / or mnemonic knowledge of matter, synthesis and analysis of non-articulating and/or correct language but not always appropriate will lead to discrete assessments; training gaps and/or inappropriate language - although in a context of minimal knowledge of the material - will lead to votes that will not exceed the sufficiency. Training gaps, inappropriate language, lack of guidance within the reference materials offered during the course will lead to failed assessments.

Teaching tools

Video projector, PC, overhead projector, traditional blackboard, pen tablet.
