Teaching methods and learning activities
Classes will be based on theoretical lectures complemented by case study analysis; Students will be asked to develop a group project on “Chemistry and Technology of…” and to present it in 2 oral presentations and discuss it throughout the semester; Seminars, mini-lectures or field trips are also foreseen in the course unit.

Eligibility for exams
To be admitted to exams the student must reach a passing grade (≥10 out of 20) in group project, must attend 50% of external activities (seminars, mini-lectures or field trips) and perform ALL mini-tests.
Calculation formula of final grade
FG = 0.40 TG + 0.45 MT + 0.15 EX
where:
FG is the final grade
TG is the average classification of the 2 presentations (15%) and the final report of the project developed throughout the semester (25%).
MT is the weighted average classification of the 3 mini-tests with 45 min of duration and performed throughout the semester, which will focus on the topics addressed in classes and seminars/mini-lectures/field trips. In each mini-test, the student should obtain a minimum grade of 7/20:
MT = 0.30 MT1 + 0.30 MT2 + 0.40 MT3
EX is the arithmetic average of 5 exercises (10 min), performed at the end of the classes, related to the theoretical classes.
To complete this course unit, students must obtain a minimum final grade, FG of 10 (out of 20).
Those students who do not achieve a passing grade will have the opportunity to make an additional written exam, which will only replace the mini-tests (MT) and exercises (EX) component. In this case, the final grade (FG1) will be given by:
FG1 = 0.40 TG + 0.60 REC
where REC is the classification of the new written exam.
To complete this course unit, students must obtain a minimum final grade, FG1 of 10 (out of 20).
Examinations or Special Assignments
Not applicable.
Special assessment (TE, DA, ...)
Not applicable.
Classification improvement
Students who have obtained eligibility for exams, may perform an extra exam.
Only the theoretical individual component (MT and EX) can be improved.
Students wishing to improve their final grades must perform an extra written exam. The final grade of the course unit, FG2, will be estimated according to:
FG2 = 0.40 TG + 0.60 REC
where:
FG2 is the final grade
TG is the average classification of the 2 presentations (15%) and the final report of the project developed throughout the semester (25%).
REC is the grade of the final exam.
To complete this course, students must meet a minimum final grade, FG2, of 10 (out of 20).
