Teaching Methods
Exposition of the syllabus in theoretical lectures, problem-solving classes in theoretical-practical lectures, and laboratory experiments performed in practical-laboratory classes. Seminars by invited specialists.
Assessment
The grades are within the interval [0,20]. Continuous assessment or by final exam, by the Academic Regulations of the University of Évora. The assessment method consists of the following components:
• [TL] Laboratory work and report (30%).
• [T1] Test 1 (35%).
• [T2] Test 2 (35%).
• [E] Final Examination (70%)
The student can choose between 1 out of 2 possible assessment methods, where the Final Grade [NF] is calculated according to the following:
i) CONTINUOUS ASSESSMENT: NF = TL*0.30 +T1*0.35 +T2*0.35 if NF> 9.5 ^ TL> 9.5 ^ T1> 8.0 ^ T2> 8.0 then student APPROVED.
ii) FINAL ASSESSMENT: NF = TL*0.3 +Ex*0.70 if NF> 9.5 ^ TL> 9.5 ^ E> 9.5 then student APPROVED.
• [TL] Laboratory work and report (30%).
• [T1] Test 1 (35%).
• [T2] Test 2 (35%).
• [E] Final Examination (70%)
