Teaching method

Lectures use modern multimedia techniques. A dynamic interaction student-tutor is established. Laboratory classes are carried out in an adequately equipped laboratory. 

Evaluation method

According to the FCT/UNL Assessment Regulations, the Course of Organic Chemistry I have the following evaluation components:

It is required to obtain the frequency of the course, which requires the achievement of three practical laboratory sessions and participation in 2/3 of the theoretical-practical sessions.

Ongoing assessment involves performing two tests and five short tests at theoretical-practical sessions and laboratory sessions. The two tests and the short tests of theoretical-practical sessions  may be replaced by a final exam, in appropriate cases, but the other portions of the assessment will stand.
The final evaluation results from the application of the following calculation formula:
(average of two test  scores x 0.35 + score average of short tests (without that one with the worst score x 0.35) (or final exam score)* + score from the practice sessions** x 0.3 = final score (should be greater than or equal to 9.5 for course approval)

* = The average grade obtained in the two tests or in the final exam will have to be compulsorily equal or superior than 9.5.

**= The score obtained in laboratory sessions will have to be compulsorily equal or superior than 9.5.

The evaluation of practical sessions of the CU will take into consideration the following components:

Preparation of the experiment (to be performed before the experimental session),

Laboratory performance,

Discussion of results.

Note: Students have purchased in previous years frequency component theoretical-practical and laboratory replaced by the recorded score, it will have a total weight of 0.3 in the final formule.
The maximum of allowed absences is stipulated by law.
