ExLab

Laboratory exam where the student will make an individual oral presentation describing the objectives, implementation and results of one of the practices. This presentation will be followed by questions related to the subject presented. The student will also deliver a handwritten summary of the chosen practice. The learning objectives for the topic to which the practice refers will be assessed, as well as the transverse competence "Effective oral and written communication".

Teaching methodology

Theoretical concepts will be covered in either theory classes followed up with problem-solving sessions or theory/problem-solving classes (at the lecturer's discretion).

Practical exercises will be completed in the laboratory sessions, preferably in pairs.

At the end of each topic there will be an additional face-to-face session of two-hours to support learning (Directed Activity).

Evaluation methodology

The technical competency mark will be based on two marks:
- A theory mark (90%).
- A laboratory or practical mark (10%).

There will be two partial tests, P1 and P2, corresponding respectively to topics 1 and 2 the first one and to topics 3 and 4 the second one, covering the four topics in which the course is structured.

Additionally, there will be six evaluable activities to be carried at the Physics Laboratory, which will include five evaluable practices and a final Lab exam, consisting of an oral presentation of one of the practices performed,
followed by a brief question session.

The grade of the course by continuous assessment will be computed by means of the expression:

NotaCursAC = 0.90 * (P1 + P2) / 2 + 0.10 * L

P1 and P2 being the marks of the partial exams and L the global note of the laboratory.
The latter will be obtained according to:

L = 0.75 * (average of practice notes) + 0.25 * ExLab

In case the student needs or wants to improve his / her mark, an optional final exam (EF) will be carried out.
In this case, the resulting grade of the course will be

NotaCursFinal = 0.90 * max (EF, (P1 + P2) / 2) + 0.10 * L


The grade of the competence on oral and written expression (CEOE) can be: A (excellence), B (optimal), C (sufficient), D (not passed).
The oral part will be evaluated on the basis of the Laboratory exam. The written part will be evaluated from a handwritten summary of the practice selected for its exposition.

The oral and written parts will have equal weigths on the final grade.

Previous capacities

Students are expected to have taken physics at upper secondary level and have basic notions of mathematical analysis. As far as skills are concerned, they should know how to learn, solve problems, search for information, make abstractions and use mathematical language.
