3. Assessment (1st and 2nd call)

3.1. Assessment tasks (description of tasks, marking system and assessment criteria)

Problems and practical cases (30/100): The resolution of these exercises constitutes an individual or group work of the students. Students must submit a report at the end of each session following the guidelines and the presentation format that will be marked. The grades and the corrected exercises themselves will be made available to students for review. These types of controls are framed within the concept of continuous evaluation, which will allow monitoring of the learning process.

Written Test (60/100): The written test will be constituted by questions that require short answers (limited response tests) or that require a broad development of the subject (essay tests or free and open answer). The first will allow a broad sampling of the student's knowledge on the subject, and the second will allow assessing their ability to express themselves, to present and sustain arguments, and to make critical judgments. The written test will be based on the program of programmed learning activities.

Seminars (10/100): Preparation of report, presentation and public defense of a work on a subject related to the subject. The report will be done individually or in groups of 2 students. The work will be exposed and defended by each group of students in seminar-type sessions. The time available for the exhibition and defense of the topic during the seminar sessions will be 10-15 minutes. It will be assessed if the work follows a coherent structure and provides an appropriate bibliography. During the presentation the clarity and order in the exhibition will be assessed, and the maturity in the debate.

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. The master classes will generally use computer screen projections (PowerPoint), including small animations, videos and off-line navigation. Blended learning methodologies will be used to exchange information with the student and to advice on the presentation of their individual work. Students are expected to participate actively in the class throughout the semester. Classroom materials will be available via Moodle. These include a repository of the lecture notes used in class, the course syllabus, as well as other course-specific learning materials.

The problems and cases will be distributed through the mixed learning platforms and after the theoretical presentation; they will be resolved and discussed in class. The blackboard will be used above all. The student will be instructed on how to design experiments, present data and results, and how to organize the discussion of them through the proposal of theoretical-practical cases. This part of the subject requires team work and individual student, as well as search and discussion of information, and resolution of specific problems. These activities will allow the student to acquire the necessary skills and abilities to analyze and solve experimental problems related to the techniques of the subject, design experiments (and/or applications) independently and describe, quantify, analyze and critically evaluate the results obtained.

The preparation of seminars and individual works will instruct students in the search for relevant information on the Internet, the use of databases, scientific bibliography and online applications. The use of original scientific material will be encouraged by the students (scientific publications, patents) and their interpretation for the presentation of information to a specialized public and the general public. This activity will help students in the practice of knowing how to communicate conclusions -and the knowledge and ultimate reasons that sustain them- in a clear and unambiguous way.

The discussion of a relevant research or technological development topic that has shown significant progress in recent years in workshops and debates will allow students to express their opinions on the subject in question, as well as to propose alternatives to the solutions presented to them.
