Exam procedures Detailed document Exams in the website Final mark F F = 0,8 S + 0,2 L + [miniproject], + [lesson notes prize] S: Exam results (written exercise + oral discussion) End-of-course sessions: 2h written test + single oral question, about 15 Other sessions: shorter written test + multiple questions oral discussion (30 ) L: lab reports Unique mark for the whole group (attending students) +1 for the best report of each experiment (with saturation at 3) Possible to repeat a single missed experiment. 15/03/2011-12 ATLCE - A0-2010 DDC

[optional additional marks] Miniproject A small project or research related with course content Developed within the time frame of the course Must produce:»a public presentation (about 15 ) to the class before course end,»a written report, delivered before the exam session. From -1 to +3 points Best Lesson Notes prize Notes from the lessons Main requirements: usable to prepare next year course» Well structured, readable, Only one winner/year Up to +3 points 15/03/2011-13 ATLCE - A0-2010 DDC

A Cell Free course (how to get - marks) Use of communication equipment: Not required Strongly discouraged Forbidden if causes any disturbance to the lesson (ringing, noise, lower attention ). In case of disturbance Identification of responsible person May be asked to carry out exercises or clarify lesson contents. Mark, from -3 to +1, which adds to the final exam mark. More safe to switch off Take responsibility for use 15/03/2011-14 ATLCE - A0-2010 DDC

Why lab experiences? Engineering: maths & realworld models + experiments Goals Verify models towards real cases Verify correctness of design procedures Practice teamworking & communication Manuals and guides in the website Preliminary homework and need to follow labetiquette Follow instructions Carry out homeworks (Workplan, design, simulations, ) Leave your bench in better conditions than how you found it. 15/03/2011-15 ATLCE - A0-2010 DDC

Cooperation and teamworking The engineer never works alone: organization and cooperation are part of real work environments Lab exercises aim also to exploit cooperation in the workplace: carrying out the experience and writing the report are collective responsibility of the working group. Only with proper preliminary organization and task assignment among the people in the group the experiment can be completed in the available time. Learn to cooperate effectively and organize your work Better to set-up mixed skill & language teams the cooperation principle does not apply to exams 15/03/2011-16 ATLCE - A0-2010 DDC
