3. Assessment (1st and 2nd call)
3.1. Assessment tasks (description of tasks, marking system and assessment criteria)
Assessment tasks are the basic elements in the entire teaching-learning process since it is the only mechanism that
allows, at any time during an educational period, to evaluate the degree of achievement of the proposed learning results and, if appropriate, apply the necessary corrections.
At the beginning of the course the student will choose one of the following two assessment methodologies:
Continuous assessment system: it is an assessment system characterized by the obligation to participate in
face-to-face activities of the subject and to take and pass practical tests, partial exams and academic works within
the established deadlines. In the case the students passes all the continuousassessment tests, they will be exempt
from the global exam.
Global final evaluation exam: it is a final and global exam on all the theoretical and practical content of the subject.
Continuous evaluation system:
Following the spirit of the reform of the European Higher Education Area (EHEA), the evaluation of the subject
contemplates a continuous evaluation system as the most consistent to be in line with the guidelines set by this new
framework. In the continuous assessment model, the professor will assess the student's participation in face-to-face activities and their ability to solve problems and laboratory practices. Finally, the student should take and pass two partial exams ("continuous assessment exams") throughout the course.
The evaluation criteria to be followed for the activities of the continuous evaluation system are:
Laboratory tasks: In each one of the laboratory activity, its development, results and conclusions will be
evaluated. Once the practice is done, a report will be delivered by Moodle platform. This activity is valued from 0 to
10 points with a minimum score of 5 to be considered as approved. These activities will be carried out in groups of
2/3 students, while the report delivery will be individually. The final score will be the arithmetic average of the partial
scores.
Proposed exercises and theoretical questions: Responsible professors of the subject will propose exercises,
problems, practical cases, theoretical questions, etc. to be solved individually. Report about these activities should
be delivered according to specific scheduling and will be valued between 0 and 10 points. The final score will be the
arithmetic average of the marks obtained in the partial deliveries.
2 written evaluation tests: They will consist of the typical written exam scored from 0 to 10 points. The final score of
this activity will be given by the arithmetic mean of the two tests. In case one the two partial scores will not reach
the minimum score of 4, in this case the activity will be considered as not approved.
The weights of the above mentioned activities are following summarized:
Individual works 5%
Laboratory activities 15%
Partial written exam 1 40%
Partial written exam 2 40%
Global final evaluation test:
The students must choose this modality when, due to their personal situation, they cannot adapt to the rhythm of
work required in the continuous assessment system, have failed any assessment test of the continuous evaluation
process or would like to improve their score.
As in the continuous evaluation system, the global final evaluation test must be aimed at check if the learning results have been achieved, as well as contribute to the acquisition of various competencies.
The global final evaluation test will have the following group of qualifying activities:
Laboratory practices: The student will deliver a report of all the laboratory activities carried out during the course
before the beginning of the global assessment written exam. test, as a sine qua non condition to pass the course.
This activity will be valued from 0 to 10 points.
Written exam: It will consist of a test that will contain questions and problems related to the topics explained
throughout the course. This test will be valued between 0 and 10 points.
The weights of the above mentioned activities are following summarized:
Laboratory activity 15%
Written exam 85%
4. Methodology, learning tasks, syllabus and resources
4.1. Methodological overview
The methodology followed in this course is oriented towards the achievement of the learning objectives. A wide range of teaching and learning tasks are implemented, such as:
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:
- Lectures: The theoretical concepts of the subject are explained.
- Practice Sessions: Problems and practical cases are carried out.
- Monitored Practices: Exercises 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 cannot be applied, support and help activities for students who need it solving doubts or providing solutions to problems connected with the units covered.
If classroom teaching were not posssible due to health reasons, it would be carried out on-line.
4.2. Learning tasks
The course includes the following learning tasks:
- Theory/Practice Lectures: Theoretical activities or problems carried out mainly through exposition by the teacher.
- Practical classes: Theoretical discussion activities or exercises and practical cases presented by students.
- Practical laboratory testing: This work is tutored by a teacher in the laboratory. These activities will continue with 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.
