Teaching methods and learning activities

Classes will take place mainly in the classroom and essentially expositive lessons.

Classes for group-work, with the support of teachers will be available.

Two field classes are planned in CELaMi and visits to Atlas Copco Portugal company and to a excavation work site in progress.

Evaluation Type

Distributed evaluation without final exam

Assessment Components

Designation	Weight (%)
Defesa pública de dissertação, de relatório de projeto ou estágio, ou de tese	20,00
Teste	40,00
Trabalho escrito	40,00
Total:	100,00

Amount of time allocated to each course unit

Designation	Time (hours)
Frequência das aulas	56,00

Eligibility for exams

75% of attendance to classes.
minimum attendance level is required to take the appeal exam.

Calculation formula of final grade

Distributed Evaluation components:

1-Assessment Test to be held during the semester - Weight in Final Grade - 40%

2 - Monograph to be undertaken in teams of 2 students - Weight in Final Grade - 60%.

The second component of the Distributed Evaluation is composed of two "products":

A Report and a Oral Presentation of 20 minutes.

To all Students holding minimum attendance rate, but not approved in the Distributed Evaluation, should undertake the Appeal Exam. In this case, the Final Grade = 100% Appeal Exam grade.

Examinations or Special Assignments

According to the general rules established at FEUP

Special assessment (TE, DA, ...)

According to FEUP regulations.

Classification improvement

At the Appeal Exam
