Teaching Methodologies and Assessment Criteria |
The methodology based on the solution of problems and laboratory tests is the closest to the practical situation where an engineer performs his job.
The assessment of knowledge is based on the final exam (individual).
1) Final Exam (individual)
The final exam (NEF) consists of a written test (NE) and oral exam (NEO). The final exam grade, NEF, is calculated as follows:
- if NE => 16 values and performed the oral exam, then NEF = NEO;
- if NE => 16 values and not performed the oral exam, then NEF = 16 values;
- if 9,5 <= NE < 16 values, then NEF = NE;
- if NE < 9.5 values, then NEF = NE ("Disapproved").
Admission to the final exam depends on obtaining attendance in accordance with the criteria below.
