5.1. Methodological overview
The learning process designed for this subject is based on the following:
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 Materials Engineering 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:
1. Face-to-face generic activities:
- Theory Classes: The theoretical concepts of the subject are explained.
- Practical Classes: Problems and practical cases are carried out.
- Monitored Practices: Exercices and practical cases are carried out, complementary to the theoretical concepts studied.
2. Supervised Autonomous Activities: These activities are carried out independently by students under the supervision of the teachers of the subject. The student will have questionnaires available per unit and suggested exercises and will be allowed to attend face-to-face or group tutorials to focus on solving them.
3. Reinforcement activities: Through the virtual learning portal (Moodle) or email of the University of Zaragoza, teachers of the subject will develop, for particular cases for which conventional tutoring can not be applied, support and help activities for students who need it solving doubts or providing solutions to problems connected with the units covered.
5.2. Learning tasks
The programme offered to the student to help them achieve their target results is made up of the following activities...
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:
- Theory/Practice Lectures: Theoretical activities or problems carried out mainly through exposition by the teacher.
- Practical classes: Theoretical discussion activities or exercices and practical cases presented by students
- Practical laboratory testing:This work is tutored by a teacher in laboratory. These activities will continue with an autonomous student work.
- Individual tutorials: These tutorials may be face-to-face or virtual (Moodle or email).
- Group tutorials: Scheduled tracking learning activities in which the teacher meets with a group of students to answer questions, exams or problems
The subject has 6 ECTS credits, which represents 150 hours of student work in the subject during the trimester, in other words, 10 hours per week for 15 weeks of class. 40% of this work (60h) will be held in the classroom and or lab and the rest will be autonomous.
A summary of a weekly timetable guide can be seen in the following table.

5.4. Course planning and calendar
For the students in continous evaluation system, the writen test will be held in the end of each section.
The final dates will be announced during the scholar year in the Moodle.
For the students in non-continous evaluation system a final test will take place the first day of the official test calendar.
The dates of the final exams will be those that are officially published at http://www.eupla.es/secretaria/academica/examenes.html.
The three laboratory test blocks will be developed along the semester.
These dates are could be modified based on the scholar activity. The definitive dates will be announced in the Moodle
