5.1. Methodological overview

SPECIALIZATION IN BUSINESS

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

 • Theoretical classes:   Theoretical activities imparted in a fundamentally expository way by the teacher, in such a way as to expose the theoretical supports of the subject, highlighting the fundamental content, structuring it in themes and relating those themes to each other.

• Practical classes:       The teacher explains and helps in understanding the use and management of necessary    software for configuring and programming control devices (PLC’s)

• Laboratory practices: Students will perform tests, measurements, assemblies, etc. in the laboratories arranged in groups, following a script provided by the teacher.

• Individual tutorials:      They will be carried out in the department through a personalized attention to the student, with the goal of solving the doubts and difficulties the student faces. These tutorials can be carried out either face-to-face or virtually.

SPECIALIZATION DEFENCE 

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

• Presentation of the course contents in master classes. During the lectures the professor will often refer to real-world examples related to the concept being introduced, both from the civilian and militar contexts.

• Resoultion of problems and exercises with the involvement of the students.

• Development of laboratory sessions guided by professors using simulation tools with the goal of digging deeply into the theoretical contents.

• Personal study of the subject by students.

It is useful to keep in mind that the course has both theoretical and practical orientation. Therefore, the learning process emphasizes both student participation in lectures, and conducting laboratory practices and solving excercise and problems.

5.2. Learning tasks

SPECIALIZATION IN BUSINESS

 The course consists of 6 ECTS credits, which represent 150 hours of student’s work during the semester, which would equal to 10 hours every week during the 15 weeks the semester lasts.

 The degree of experimentation is deemed high.

The student’s activities in this semester, organised by duration are as follows:

• 25 hours of master classes (theoretical teaching and problem solving)
• 25 hours of laboratory practice, arranged in 2 hour sessions
• 10 hours of tests (written and practical)
• 90 hours of personal studying

SPECIALIZATION DEFENCE

The master classes are organized as:

• Theory: Theorectical concepts are introduced with examples based on real systems related with the future work place of the students. Also, excercises will be solved in the classroom to help the assimilation of the theoretical concepts.
• Laboratory: Practical modeling, analisys and control of real systems simulated in a computer.

The subject consists of 6 ECTS credits that correspond to 150h of students' work.

The work is distributed as follows: 

• 47-49h of master classes (theory and excercise)
• 6-8h of laboratory sessions (2h each)
• 5h of exams and tests
• 90h of students' personal study

Before the beginning of the semester, the professors will provide to the students the schedule of the activities using the Moodle platform. This can be consulted going to http://moodle.unizar.es and authenticating with their username and password.

They will find the detailed course program, teaching documents and recommended bibliography in addition to suggestions to follow it.

Additionally, it is possible to find information such as the classes calendar and hours at the web page of the Centro Universitario de la Defensa: http://cud.unizar.es.
