Teaching Methodologies
6.1 TEACHING METHODS
The methodological options leading to the fulfilment of the curricular unit’s program will focus on the following pedagogical strategy:
– oral presentation oriented to the estimated contents;
– work developed under the teacher guidance.
6.2 EVALUATION METHODS
Given the specificity of this curricular unit, the student must guarantee a minimum presence in 42 contact hours (classes), with the right to take an exam, in case he/she has not been approved by continuous assessment.
The work to be carried out will comply with criteria that will be explained in the statements and/or other elements presented, according to the following components and weights:
CONTINUOUS EVALUATION
– Exercise 1 – 15% weight in the assessment;
– Exercise 2 – 35% weight in the assessment;
– Exercise 3 – 50% weight in the assessment
EXAM
– Component Theoretical-practical – 50% of the evaluation
– Component practical – 50% of the evaluation
