Methodologies
Methodologies   ::  
  Description
Problem solving, classroom exercises Face-to-face practical class. Solving exercises on the board and discussing them.
Laboratory practicals Mandatory face-to-face class where laboratory practices are carried out, followed by the treatment and interpretation of the obtained data.
Personal tuition Face-to-face resolution of doubts and guidance on the topics covered in the different theoretical-practical sessions.
Seminars Classes with the development of exercises of a higher level, corresponding to the topics of the course program
Lecture Face-to-face theoretical class where the contents of the course are explained.

Description
The tutorials will be in person (individual or group) or through the Moodle platform

Assessment
  Description Qualification
Problem solving, classroom exercises Problem-solving/exercises in the regular classroom: Attempt problem-solving and actively participate in their discussion 60%
Laboratory practicals Mandatory attendance. Methodical and careful completion of laboratory practice. Neatness and precision in the treatment of obtained data 15%
Lecture Assimilation and understanding of the explanations given in class. Knowledge will be assessed through two partial tests 15%
Others Problem-solving after each topic 10%
 
Other comments and second call

The knowledge acquired in the "Master Sessions" and in the "problem-solving classes" will be evaluated in two partial exams, each contributing 37.5% to the final grade. Attendance to all practical sessions is mandatory, and the practical grade constitutes 15% of the final grade. In case of inability to attend any of the practical sessions due to sufficiently serious reasons, it is mandatory to provide evidence of such reasons by presenting a properly signed justification. For each missed practical session, an exam must be taken on the same day as the first regular call, in addition to the scheduled tests. The remaining 10% of the grade will come from periodic assessments conducted after the completion of each topic. The course can be passed in the first call through two avenues:

 

Passing both partial exams (it is necessary to obtain at least 50% of the total grade in each partial exam)

Passing the overall final exam in the first call

Second Ordinary Call: Students who have not passed the course in the first call must take an exam covering the entire material taught.

 

During any face-to-face activity (lectures, exams, practical sessions, etc.), the use and mere possession of electronic devices that enable communication (mobile phones, radios, etc.) are expressly prohibited, unless authorized by the professor. The professor will inform students at the beginning of the teaching period and/or prior to the evaluation tests, through the communication channel deemed appropriate (Moodle, notice board, classroom, email, etc.) about the materials, means, and additional resources necessary and prohibited for the development of exams or evaluation tests. In case of any irregularity during the evaluation test, based on the corresponding current regulations, the exam will be withdrawn, the student will be expelled, and the grade will be recorded as a fail.
