Syllabus Information

5.1. Methodological overview

The methodology followed in this course is oriented towards achievement of the learning objectives. It promotes continuous work and focuses on the basic theoretical aspects necessary to understand, analyse and apply to solve real problems. A wide range of teaching and learning tasks are implemented, such as

• Lectures, where the whole group receives the theoretical concepts of the course complemented with problem-solving tasks.
• Laboratory sessions, which will be carried out in groups of two or three students. The goal of these sessions is to apply the knowledge acquired in lectures, paying special attention to the connection of circuits, electrical measurements and the connection and use of electrical machines. With these sessions the students will become familiar with electrical apparatus and machines, get manual experience, and strengthen their theoretical knowledge.
• Along the course, students will carry out some assignments supervised by the lecturer.

Classroom materials will be available via Moodle. These include a repository of the lecture notes used in class, the course syllabus, as well as other course-specific learning materials. 

5.2. Learning tasks

The course includes the following learning tasks:

• Lectures (45 hours). Explanatory sessions of the theoretical concepts will be carried out, related to the different types of electrical machines (constructive parts, operation principles, connections, etc.). The student will have material prepared by the lecturers available on the Moodle platform (http://moodle.unizar.es/), which will help following the theory sessions. Additionally, problems and practical cases related to lectures will be solved (circuit analysis, electrical machines selection, etc.)
• Laboratory sessions (15 hours). The student will have a set of task guidelines for each session available on Moodle (http://moodle.unizar.es/). They must be read prior to each session, and they will include the annotations made by the student during the session.
• Guided assignments (15 hours). At the end of each topic, the students will be offered the possibility of solving problems and practical cases proposed by the lecturer, similar to the ones solved in lectures. The problems will be available on Moodle. 
• Autonomous work and study (72 hours). Distribution of coursework along the 15 weeks of the course. Continuous work will be encouraged, distributing learning task in a homogeneous way along this period.
• Assessment (3 hours). Besides its grading function, evaluation is also a learning tool for the student to assess the degree of understanding and assimilation of the acquired knowledge and abilities.
