Bibliography

Didactic methods

Lessons take place face to face. During the lessons the theoretical topics are dealt with and immediately afterwards many exercises are carried out for the application of theoretical concepts and for preparation for the final exam. If it is not required by the health emergency or by the university, lessons are not carried out in streaming or recorded as these methods prevent free discussion between students and teachers.

Learning assessment procedures

Written exam with n = 8-15 open question exercises. Duration 2 hours maximum. No books or notes are allowed. Bring calculator and pen and ID. The sheets will be distributed by the teacher. Write your name, surname and serial number on all the sheets delivered. It is possible to make a draft. All the sheets (even the draft) must be returned at the end of the exam. The text written in pencil will not be considered in the evaluation. The exercises can be carried out in a different order from that indicated in the text but the number of the exercise to which it refers must be clearly indicated before the exercise. Two or more different solutions of the same exercise are not allowed.
In the event of a health emergency, the examination procedure can only be oral via the web.

Evaluation criteria

The correctness of the procedure adopted by the student to solve the exercises and the use of units of measurement will be taken into account. Alternative solutions are welcome, as long as they are correct. Calculation errors that lead to solutions that are incompatible with the problem are considered serious.

Criteria for the composition of the final grade

Indicatively, for n exercises, each correct exercise is worth 30 / n. It will then take into account the seriousness of the errors and gaps, any correct procedures even in the presence of calculation errors, clarity in the mathematical passages and the order of the paper.
