Methodologies
Methodologies Description
Guest lecture / keynote speech Guest lecture -with the help of slides and blackboard- of the theoretical contents of the subject. The active participation of the students will be fostered with questions whose answer will require some kind of reasoning requiring the application of the knowledge acquired until then.
Laboratory practice The students wil develop a series of practicals in the Electronics Laboratory, working with proper devices (circuits) and the available measurements material. Together with such practicals, the students will have to answer a set of questions related to the subjects to be developed in each case.
ICT practicals The students will develop a series of computer practicals with an electronic circuits simulation software tool (PSpice).
Supervised projects The students will have to develop, independently, a project proposed by the professor of practicals using the ITC electronic circuits simulation software tool PSpice. Besides, at the end of the course, those students who passed the subject will be able to request to perform an additional project (independently) in order to opt to raise the score (see assessment section). The theme of such a project will be proposed by the professor and it will be related to some of the contents of the subject.
Speaking test Presentation and speaking defense by the student of the practice project proposed by the professor.
Problem solving Guest lecture -with the help of slides and blackboard- of the solving of some problems similar to those that will be included in the mixed exam. The student will have to solve, on dates previously specified and with the same methodology of that of an exam, a set of tests proposed by the professor. Each test will consist of two simple problems and a question whose answer will have to be reasonably justified.
Mixed objective/subjective test Written test containing questions related to theory and problem solving about the contents given during the lecture sessions of the whole course, in which both the comprehension of such contents and their application to problem solving will be assessed.

Laboratory practice: listen to and solve questions from the students in relation to the practices proposed or realized in the laboratory.

ITC practicals: listen to and solve questions from the students in relation to the practicals proposed or realized with the help of the simulation software tools.

Supervised projects: listen to and solve questions from the students in relation to the independent realization of a project proposed by the professor of practices.

Speaking test: reasoning with the student the results of the supervised project proposed by the practices professor, with the aim of verifying the comprehension of it and determine both the degree of exploitation of the practices performed in the Electronics Laboratory and the capacity of the student for the critical analysis in problems solving.

Problems solving: listen to and solve questions from the students in relation to the problems solved in class. For the case of the defense of the presented projects, reasoning with the student the results obtained in the problems proposed by the professor, determining his/her judgement and problem solving capacities.

In all cases, communication with the students will take place using the individual tutoring hours, through email, or by making use of the corresponding Moodle tools. These two last cases will be particularly adequate for those students with academic dispensation of exemption attendance.

For those students registered part-time the timetable the tutoring hours could be adapted according to their needs.

Assessment comments

Description of the scoring
obtained in the exam.

The student may obtain:

A) UP TO 6 POINTS OBTAINED
IN THE MIXED TEST, WITH A MINIMUM OF 3 (IN THIS SECTION) TO PASS THE SUBJECT.
THE MAXIMUM TIME LAPSE OF EACH MID-COURSE EXAM (SEE NEXT PARAGRAPH) WILL BE 2
HOURS. THE MAXIMUM TIME LAPSE OF THE FINAL EXAM WILL BE 3 HOURS.

The mixed test will consist of two exams of theory and problems solving
in correspondence with the contents of the subject developed over the quarter.
The student will have two options: whether to pass the mixed test by means of mid-course
exams (one with contents related to the first three chapters, and one with
contents related to the rest of the subject) or to pass both through the final
mixed test (final exam). The first option is particularly suitable for those students
registered part time and with academic dispensation of exemption attendance.  To pass the subject it will be required to
obtain 3 points of 6 as a minimum in each of the two mixed tests that compose
the exam. The final score will be the average of the scores obtained in each
mid-term exam. The student that passed one of the mid-term exams will just have
to pass the remaining one.

B) UP TO 2 POINTS OBTAINED
IN THE PROBLEMS SOLVING CONTINUOUS ASSESSMENT, WITH A MINIMUM OF 1 (IN THIS
SECTION) TO PASS THE SUBJECT. IF THE STUDENT DOES NOT PASS THE PROBLEM SOLVING
(SEE DETAILS BELOW) IT WILL BE NECESSARY TO PASS AN ADDITIONAL FINAL PROBLEM-SOLVING
EXAM (WHICH WILL BE INCLUDED WITHIN THE SAME TIME FRAME OF THE FINAL EXAM).

Attending the problems solving
lectures is not mandatory. The continuous evaluation will consist of problem
solving grouped in tests (consisting of 2 problems to solve and one reasoned
question), which may be solved at dates previously specified. The maximum time
lapse for each test will be 10 minutes. Those students that do not pass more
than 3 tests, or those that do not obtain at least 1 point in the final score
of this section, will have to pass an additional final problem-solving exam on
dates specified for the final mixed exam. Such additional exam will consist of
3 problems with the highest difficulty, though within the level of the problems
solved in the corresponding problem-solving lectures. In such a case, the
student will pass such an additional exam only if 1 out of 2 points is
obtained. This option is particularly
suitable for those students registered part time and with academic dispensation
of exemption attendance.  

C) UP TO 2 POINTS OBTAINED
IN THE LABORATORY MEASUREMENTS PRACTICES AND ITC PRACTICALS CONTINUOUS ASSESSMENT,
TOGETHER WITH THE SUPERVISED PROYECT (WHOSE SCORE IS, AT MOST, 0.5 POINTS),
WITH 1 POINT AS A MINIMUM TO PASS THE SUBJECT. IF THE STUDENT DOES NOT PASS THE
PRACTICES (SEE DETAILS BELOW), THEN HE/SHE WILL HAVE TO PASS AN ADDITIONAL LAB-AND-ITC
THEORETICAL-PRACTICAL EXAM (WHICH WILL BE PERFORMED AFTER FINISHING THE FINAL
MIXED EXAM, AND WHOSE MAXIMUM DURATION WILL BE 1 HOUR).

In the evaluation of the
practices it will be compulsory to have 1 out of 2 points from the scorings of
the laboratory practices, ITC practicals and the supervised project, delivered
to the professor through laboratory guides correspondingly completed by each
student. At the beginning of each practice, the student will have to write the
answers to a set of three (3) brief questions (tests) related to the
abovementioned practice. If the student does not answer correctly at least two
of those questions, the score obtained in the practice will be halved. To pass
the subject, the student will not have to fail more than 3 of such tests. Those
students that do not pass this section (practices) will have to pass an
additional lab-and-ITC theoretical-practical exam on dates matching those of
the final mixed exam. This option
is particularly suitable for those students registered part time and with
academic dispensation of exemption attendance.  Such an exam will consist of a set of
questions related with the practices developed in the classes, together with
questions related to the equipment handling. A minimum of 1 point out of 2 will
be required to pass such an exam.

D) UP TO 1 (ADDITINAL) POINT
FOR ATTENDING THE LECTURE CLASSES AND/OR PERFORMING A PROJECT SUGGESTED BY THE
PROFESSOR.

Attending the lecture classes
will not be mandatory. At the discretion of the teacher, attending the classes
and a positive attitude of the student may be assessed positively with 1
additional point added to the global score. As an alternative to this option,
the student will have the opportunity of presenting a written project related
to any of the subject chapters, and whose contents and length will be specified
by the professor (though the length will not exceed 30 DINA4 pages, simple line
spacing, New Roman 10pt font type -or similar- with 2 cm margins to both sides
of the sheet).  

 

E) THE TOTAL SCORE OF THE
SUBJECT WILL BE THE SUM OF THE POINTS SPECIFIED ABOVE, UP TO 10 POINTS.

The evaluation criteria
under table A-III/6 of STCW code, and included in the Quality Assurance System,
will be taken into account when designing and performing the evaluation.
