Teaching method

The teaching-learning process includes classroom and laboratorial classes  moments as follows:


Lectures of 1 hour, supported by presentations in video projector, simulations and demonstrations.. Some classes will be reserved for the presentation of topics of the syllabus for the students.


Laboratorial Classes:

Presential classes and in groups, lasting for two hours.

Evaluation method

1.Completion  of  5 experimental  sections on production techniques and characterization of thin films. Preparation of a report and a presentation about the production of a particular thin film and  characterization. In this component will be assigned a rating, NP. This note must be greater than or equal to ten values ​​for the student to be admitted to the examination or approval of the discipline.

2. Completion of  two tests. In this component, the average of the two tests will be assigned a rating, NT. The average of the tests must be greater than or equal to ten values ​​for approval of the discipline.

3. Presentation on a topic to be determined. In this component will be assigned a rating, NA.

4. The final NF continuous assessment will be given taking into account the following relationship:

NF=0,5NT + 0,3NP +0,2NA

To pass the subject of this note will be greater than or equal to ten values​​.

5.Se the student for the examination score shall be obtained by the expression defined in the previous section by replacing the average grade of the exam grade tests. To pass the subject of this note will be greater than or equal to ten values​​.

6.All ratings will be given values ​​between 0 and 20 classifications of components are rounded to one decimal place and the final units.
