Teaching Methodologies and Assessment Criteria |
The purpose of theoretical contact hours is to transmit the theoretical knowledge associated with the programmatic content of the curricular unit. The purpose of theoretical-practical contact hours is to transmit practical knowledge to students through the resolution of practical exercises. Laboratory experiments are developed in laboratory classes.
During the teaching and learning period, three sets of exercises are proposed, which must be solved individually. The proposed exercises address the topics of the subject matter taught.
Assessment by Frequency: 30% Exercise Series + {[(35% Frequency 1 (>=7.0) + (35% Frequency 2 (>=7.0))]}
Assessment by Exam: 30% Exercise Series + 70% Exam (>=7.0)}
Minimum grade in each frequency: 7.0.
Minimum grade in the average of the exercise series: 7.0.
The grades of the Exercise Series are considered in all assessment periods.
Class attendance considers a minimum attendance of 80% of the classes taught.
