Course Description:
STUDENTS ARE EXPECTED TO HAVE COMPLETED - Linear Algebra - Calculus I - Physics I COMPETENCES AND SKILLS THAT WILL BE ACQUIRED AND LEARNING RESULTS. The main skills to be developed in these activities are: - To understand the statement of the problem (for instance drawing an scheme that summarizes the statement) - To identify the physical phenomenon involved in the statement and the physical laws related to it. - To develop a strategy to reach the objective (for instance breaking the problem in small sub-problems). - To be careful in the use of mathematics - To analyze the result The main skills to be developed in this activity are: - To understand that physics is an experimental science and they can reproduce the laws that have been theoretically explained in the lectures - To use scientific instruments and to be careful in its operation - To be careful in the acquisition of the experimental data - To learn the basis of the management of a scientific data set - Understanding and use of the scientific method and the scientific-technical language. - To write a report with the main results of the experiment - To reason in a critical way these results: have we achieve the goals of the experiment?

LEARNING ACTIVITIES AND METHODOLOGY - Lectures, where the theoretical concepts are explained and personal work of the student. They are aimed at the acquisition of theoretical knowledge. - Practical laboratory sessions of mandatory attendance; practical sessions for small groups, with active and direct interaction between the students and the professor; individual tutor supported sessions and students personal work. They are aimed at the acquisition of practical skill related to the syllabus of the subject . ASSESSMENT SYSTEM Assessment system: 1- Laboratory sessions (15% of final mark) Attendance to the laboratory sessions is compulsory. Página 2 de 3 Evaluation of the reports. The mark is shared by the members of the group. 2- Activities in groups (25% of final mark) Attendance. Short test exams. Delivery and evaluation of the proposed activities 3- Written exam (60% of final mark) This exam is made at the end of the semester and it is the same for all the students Contents: Problems to be solved covering the topics of the program and perhaps Short theoretical questions 4- Mandantory evaluation criteria: - Attendance and participation in all laboratory sension is mandatory. - Students must get a minimun grade of 3 pts, of a maximun of 10 pts, in the end of term examination. Failure to meet this two criteria will result in a failing grade (F: Suspenso) for the course. % end-of-term-examination: 60 % of continuous assessment (assigments, laboratory, practicals…): 40 BASIC BIBLIOGRAPHY - Paul A.
