Attendance regulation: at least 80% students’ attendance.

1/ Along the semester, groups of 2 or 3 students practice the process of engineering
design on a “new need”.
2/ Each group prepares presentations of design reviews: SRR, SDR, PDR, and a Final
Teaching arrangement and method of instruction
1/ Frontal lecturing with interactive involvement of the audience.
2/ Two weekly lectures,
3/ Two weekly hours of promoting the assignments.
