5.1. Methodological overview

The learning process designed for this subject is based on the following:

SPECIALIZATION IN BUSINESS

Strong interaction between the teacher/student. This interaction is brought into being through a division of work and responsibilities between the students and the teacher. Nevertheless, it must be taken into account that, to a certain degree, students can set their learning pace based on their own needs and availability, following the guidelines set by the teacher.

The current subject fundamentals of Electrotechnics is conceived as a stand-alone combination of contents, yet organized into three fundamental and complementary forms, which are: the theoretical concepts of each teaching unit, the solving of problems or resolution of questions and laboratory work, at the same time supported by other activities.

The organization of teaching will be carried out using the following steps:

• Theory Classes: Theoretical activities carried out mainly through exposition by the teacher, where the theoretical supports of the subject are displayed, highlighting the fundamental, structuring them in topics and or sections, interrelating them.
• Practical Classes: The teacher resolves practical problems or cases for demonstrative purposes. This type of teaching complements the theory shown in the lectures with practical aspects.
• Laboratory Workshop: The lecture group is divided up into various groups, according to the number of registered students, in order to make up smaller sized groups.
• Group Tutorials: Programmed activities of learning follow-up in which the teacher meets with a group of students to guide their work of autonomous learning and supervision of works directed or requiring a very high degree of advice by the teacher.
• Individual Tutorials: Those carried out giving individual, personalized attention with a teacher from the department. Said tutorials may be in person or online.

Defence profile

Ongoing study and effort are essential to achieve the learning outcomes of this course.

The methodology is based on lectures, practical classes with student participation, laboratory sessions. Some individual graded assignments are issued throughout the semester, such as homework, quizzes and other activities, trying to encourage the continued work of students.

5.2. Learning tasks

The programme offered to the student to help them achieve their target results is made up of the following activities...

SPECIALIZATION IN BUSINESS

Involves the active participation of the student, in a way that the results achieved in the learning process are developed, not taking away from those already set out, the activities are the following:

• Face-to-face generic activities:

Theory Classes: The theoretical concepts of the subject are explained and illustrative examples are developed as support to the theory when necessary.

Practical Classes: Problems and practical cases are carried out, complementary to the theoretical concepts studied.      

Laboratory Workshop: This work is tutored by a teacher, in groups of no more than 20 students.

• Generic non-class activities:

Study and understanding of the theory taught in the lectures.

Understanding and assimilation of the problems and practical cases solved in the practical classes.

Preparation of seminars, solutions to proposed problems, etc.

Preparation of laboratory workshops, preparation of summaries and reports.

Preparation of the written tests for continuous assessment and final exams.

• Tutored autonomous activities.

Although they will have more of a face character have been taken into account in part for their idiosyncrasies, they will be primarily focused on seminars and tutorials under the supervision of the teacher.

• Reinforcement activities.

Non-contact marking character, through a virtual learning portal (Moodle) various activities that reinforce the basic contents of the subject be addressed. These activities can be customized or not, controlling their realization through it.

Defence profile

• Lectures: The topics addressed are the fundamental principles of electrical circuits, the operating principles of their elements, techniques and procedures for circuit analysis and study, and the operating principles of the most common electrical machines, as well as basic selection criteria. Student participation is encouraged.

• Problem classes: In order to illustrate the application of different procedures and techniques presented during the lectures, several problem cases are solved with the active collaboration of students.

• Laboratory sessions: With the aim of achieving a meaningful learning, many of the concepts presented in the lecture sessions are applied in the laboratory. Many working techniques on electrical circuits are exercised in the laboratory, students acquire skills in the use of electrical measuring devices and they also acquire awareness of electrical hazards, being able to implement basic actions to avoid unsafe work conditions.

• Evaluable Activities: There are two types:

  • Some consist of the resolution by the students, in their study time, of different exercises proposed by the teacher. The correction and marking of these exercises provides information to students about the work that has developed.

  • The second type of assessment activities involves the resolution of brief questionnaires, for a certain time of a lecture session, that require the direct application of concepts to be seeing throughout the semester.

• TOPIC 5: Single phase transformers.
• TOPIC 6: Three phase transformers.
• TOPIC 7: Direct current motors.
• TOPIC 8: Three phase asynchronous motors.

PRACTICAL CONTENTS.

Those workshop to be developed in the laboratory, which will be performed by students in sessions of one hour below.

• WORKSHOP 1: Measurement Resistance.
• WORKSHOP 2: Measurement capabilities.
• WORKSHOP 3: Measurement inductances.
• WORKSHOP 4: Electrical measurements in sinusoidal steady series RLC circuit.
• WORKSHOP 5: Measure Direct current power.
