3. Assessment (1st and 2nd call)
3.1. Assessment tasks (description of tasks, marking system and assessment criteria)
The assessment must be understood as a continuous and individualized process throughout the entire teaching-learning period, prioritizing the capacities and abilities of each student, as well as their performance.
At the beginning of the course, the student will choose one of the following two assessment methodologies:
A) A continuous assessment system, which is carried out throughout the entire learning period. Characterized by the obligation to take and pass the practical tests, partial exams and academic tasks proposed in the subject, within the deadlines established for this purpose. In this case, the student does not have to take a final exam.
B) A global assessment test, showing the achievement of learning results, at the end of the teaching period. Characterized by not taking or not passing the practical tests, partial exams or academic work proposed in the subject. In this case, the student must compulsorily take the final exam.
Breakdown and content of each assessment system:
The continuous assessment system consists of three blocks that are explained below. The first condition is that the student must attend at least 80% of the classroom activities.
1st Block: Continuous assessment exercises: The student will carry out a total of 5 continuous assessment exercises (one per chapter) on a compulsory basis in the continuous assessment system, which will be distributed throughout the course. Each exercise will be delivered to the student once the corresponding theory topics and exercises have been completed. The student will have a week to do it and deliver it to the teacher, since this activity is continuous and should not be delayed in time. The continuous assessment exercise will be very similar to the exercises carried out in class. In addition, the student will have tutorials to answer any questions about it. This activity will globally account for 30% of the final grade for the course. To take this grade into account the student must meet two requeriments:
- 1st They will have to deliver all the exercises within the period given by the teacher. Otherwise, this activity will be considered as a fail (except for properly justified major cause).
- 2nd They will have to obtain a minimum of 3.0 in each exercise. And you must obtain a minimum grade of 4.0 with all the exercises included. If not, this activity will be considered as a fail.
2nd Block: Written tests for continuous assessment. The student will take a total of four compulsory written tests in the continuous assessment system, which will be distributed throughout the course. These tests will include theoretical questions and exercises on the corresponding topics. The duration of the test will be a minimum of two hours of classes and a maximum of three, depending on the case. This activity will globally account for 50% of the final grade of the course, to take this mark into account, the student must fulfill two requirements:
- 1st They will have to turn up in all the tests in the date given by the professor. Otherwise, this activity will be considered as a fail (except for properly justified major cause).
- 2nd They will have to obtain a minimum of 3.0 in each test. And they must obtain, including all the tests, a minimum grade of 4.0. If not, this activity will be considered as a fail.
3rd Block: Computer-Assisted Practices. The student will carry out two compulsory practice sessions in the continuous assessment system, which will be distributed throughout the course, according to the planning chart. This activity will globally account for 20% of the final grade for the course, to take this grade into account the student must meet two requirements:
- 1st They will have to attend all practice sessions on the date given by the teacher. Otherwise, this activity will be considered as a fail (except for properly justified major cause).
- 2nd They will have to obtain a minimum of 3.0 in each practice. And they must obtain a minimum grade of 4.0 including all the practices. If not, this activity will be considered as a fail.
Prior to the first call, the teacher will notify each student whether or not they have passed the subject depending on the use of the continuous assessment system, based on the sum of the scores obtained in the different activities carried out throughout it. according to the formulation:
Final mark of the subject in THE first call = 50% A + 30% B + 20% C
A = Average grade of written tests
B = Average grade of exercises
C = Average mark of practice task
Thus, they must obtain a minimum grade of 5.0 to pass the course, fulfilling all the above mentioned and explained requirements. The students who have passed the subject in this way, will be allowed to increase their grade on the first call (never to lower it).
Global Test: In case of not passing with the previous system, the student will have two additional calls (June and September) with a global assessment test. This test will be unique with theory and exercises representative of the entire syllabus of the subject contributing 100% to the final grade of the course.
4. Methodology, learning tasks, syllabus and resources
4.1. Methodological overview
"If classroom teaching were not posssible due to health reasons, it would be carried out on-line"
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 (Mechanical 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:
— Lectures: 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: Practical activities will be conducted in the computer room 1.1 software mechanism (GIM 16.0) with the presence and teacher mentoring.
— Individual Tutorials: Those carried out giving individual, personalized attention with a teacher from the department. Said tutorials may be in person or online.
4.2. Learning tasks
Programmed learning activities
|
The program 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:
— Face-to-face generic activities:
● Theory sessions: The theoretical concepts of the subject are explained and illustrative examples are developed as a support to the theory when necessary.
●Practice Sessions: 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.
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.
A summary of a weekly timetable guide can be seen in the following table. These figures are obtained from the subject file in the Accreditation Report of the degree, taking into account the level of experimentation considered for the said subject is moderate.
