Teaching method
Theoretical classrooms data show. Practical laboratory sessions.
Evaluation method
- Continuous assessment with 4 elements of evaluation:
Theoretical-Practical Evaluation: 2 Tests (each one 30% to the final grade). Weighted average of the 2 elements of evaluation must be equal or higher than 9.5 values (scale of 20).
Laboratorial Evaluation: 1) Assiduity of the practical laboratorial sessions; (2) Elaboration and discussion of two practical reports (each one 20% to the final grade).
Frequency is obtained with the presence in 2/3 of practical classes.
Final rating: (0.60*Theoretical-Practical Evaluation) + (0.40*Laboratorial Evaluation). Approval is obtained with a minimum score of 9.5 (scale of 20).
- Students without approval on the continuous assessment examination can proceed to the final exam, with the classification being defined by: 0.60 *Exam + 0.40*Classification of the Laboratorial Evaluation. Approval is obtained with a minimum score of 9.5 (scale of 20).
- Improvement of the classification requires a registration in the schedule examination period. The classification of the practical component cannot be improved and follows in the next year.
