Teaching method
Lectures consist of a theoretical exposition, illustrated by application examples, and supported by slides and the usage of the software development environment of the lecturer.
In the lab sessions, students solve problems by concretely applying the concepts discussed in the previous lectures.
Students may clarify any doubts during classes or in the instructor’s contact hours.
Evaluation method
Evaluation Components
The evaluation contains a theory and practice component, as well as a lab component.
Lab Component and frequency
The lab component is worth 55% of the final grade.
1st Project (P1): made by teams of 2 students, with two partial deliverables. This project is worth 35% of the final grade (15% for the first partial deliverable, 20% for the second partial deliverable).
2nd Project (P2): made by teams of 2 students, with a single delivery. This project is worth 20% of the final grade.
To obtain frequency, a student needs to obtain a weighted average of the lab component >= 9.5. Frequencies obtained in 2019/2020 remain valid, and so does the corresponding grade.
Theory and Practice Component
The theory and practice component includes two individual tests and is worth 45% of the final grade.
1st Test (T1): Test performed online, where the student is allowed two have 2 manuscript pages to consult. This test is worth 15% of the final grade.
2nd Test (T1): Test performed in presence, as long as the sanitary conditions allow it, with no access to consultation materials. Students are allowed to use a basic pocket calculator. This test is worth 30% of the final grade.
The theory and practice component grade is the weighted average of the test grades, or the exam grade (Ex). To be approved, a student must obtain a theory and practice grade >= 9.5 and have a valid frequency.
Final Grade
When this course is made through tests, the final grade is:
NF = T1 * 0.15 + T2 * 0.30 + P1 * 0.35 + P2 * 0.20
When this course is made through an exam, the final grade is:
NF = Ex *0.45 + P1 * 0.35 + P2 * 0.20
To be approved, the student must have frequency and a theory and practice grade >= 9.5.
If the theory and practice grade is < 9.5, the final grade is the theory and practice grade.
