Métodos de ensino e atividades de aprendizagem

In TP classes one tries not to impose contents, but to ask students to rediscover, by themselves (and with a little guidance), the syllabus topics.

PL classes are used to perform laboratory work and to solve engineering design problems related to real live examples.

Autonomous work is promoted and:

a. at least one tasks should be written in English

b. at least one presentation should be in English

c. task groups aim at the promotion of group dynamics, promoting leadership, cooperation and responsibility

d. at least one task considers the solution to a real live example (preferably suggested by an external institution).

Continuous assessment includes tests (60%) and practical assignments (20%) and laboratory assignments (20% of final grade). An alternative assessment is based on a final exam (100% of final grade) dependent on the approval in mandatory practical assignments. Approval in exames, tests, practical and laboratory assignments requires 10 (in 20) minimum grade.

Fórmula de cálculo da classificação final

(grade obtained in tests)*0.6 + (grade obtained in practical assignements)*0,20 + (grade obtained laboratory assignment)*0,20 [considering lowest admissible grade]
OR
1.00*(grade obtained in exam) [considering lowest admissible grade]
