Exam under lifesize (AGO1 meeting room)

Adaptation des engagements pédagogiques suite à la pandémie de COVID-19 pour la session août-sept

Matière de l'évaluation

The original plan for exam was:
The student is assigned randomly two questions from the list of exam questions distributed at the beginning of the lessons. He than had the whole morning or afternoon preparing his exam using a two-sided page with formulas he had prepared to help him (vademecum). The exam then focussed on checking how well the student mastered the concepts and understood the physics.
In view of the new situation it makes little sense to let students prepare for several hours the exam alone in front of a camera. Therefore the exam will be held with the pdf file of the lectures accessible by students and shared by them (so the pdf file can be annoted by them). The list of questions is still the same and two of them will still be chosen randomly during the exam, but from that moment on, the student will be asked to present the question with an eye on one additional specific aspect of the problem (e.g. Where is the hypothesis that the bottom is flat coming in and what does this eliminate as possible processes). Preparation is then done within 15 minutes and the questions presented and discussed.
Alternatively, instead of preparing the original list of questions, a student can decide to prepare TWO of the following chapters of the reference book (not discussed during the lessons but follow-ups of the theory covered)
13.5 Lee Waves 15.5 Atmospheric Frontogenesis 16.6 Some Nonlinear Effects 17.6 Bulk Criteria 18.2 Vortices 19.3 Direct and Indirect Convective Cells 21.3 El NiQno - Southern Oscillation (ENSO)
and then present one of the two chosen randomly.
Should internet become unstable or unavailable, please provide me with a phone number where I can reach you during the exam (send it to me the day before the exam). Also make sure your computer has been updated recently to avoid forced updates during the exam and no other program is running. Also it could be a good idea to restart your internet router earlier that day.
