Teaching Methodologies and Assessment Criteria The transmission of the syllabus is based essentially on theoretical exposition, followed by general questions to the students to promote dialogue. In this course the practical classes are used for applications of the syllabus taught, to resolved issues/problems in a group or individually way.
The evaluation consists on written individual tests.
Language Portuguese. Tutorial support is available in English.
