Teaching Methods

Teaching is based on theoretical, theoretical-practical and laboratory classes. Theoretical classes are taught with projection of presentations and explanations of the content, examples and resolution of simple problems.
In theoretical-practical classes, complex problems are addressed through the resolution of series of exercises relating to the various topics covered in theoretical classes.
Practical laboratory classes involve the development and physical implementation of electronic circuits by students through the use of the concepts learned and discrete components installed on breadboards.
It is intended that the student has contact with the various components and instruments used in analog electronics.
Private lessons for students available outside of class, 2 times a week at 2 hour intervals each. Email available for basic questions or to reschedule private times according to each student.

Assessment

The evaluation of the results of the teaching-learning process provides for a final ?grade? and expressed on a numerical scale from 0 to 20 points.
The assessment is made up of two parts: Theoretical (70%) and Laboratory (30%)
Theoretical part: 2 intermediate tests (F1 and F2) or Final Exam (Ex) in the normal, appeal, special and extraordinary periods:
Minimum theoretical grade 9.5
-[F1] Test 1 - Minimum grade 9.0 (35%)
- [F2] Test 2 - Minimum grade 9.0 (35%)
- [Ex] Final Exam (70%)
Laboratory Part: Six Laboratory Works covering theoretical material. Continuous assessment of student performance (20%);
Evaluation of reports prepared (40%); Oral about the work carried out (40%)
Laboratory Part (L): Minimum practical grade 9.5
[NF] Final Grade: NF = Max{(F1 + F2)/2; Ex}*0.7 + L*0.3
If NF>= 9.5: Approved
If NF
