Objectives

Objectives 

One intends to focus the fundamental concepts of Condensed Matter, emphasizing the applications to engineering and life problem systematization and solving. Fundamental proprieties of Condensed Matter will be verified in experimental laboratory sessions, involving the comprehension of experimental setups, data collecting and treatment systematization and elaboration of scientific reports.

Evaluation method

5. Assessment elements

5.1. Laboratorial component

5.1.  Preparation of five experimental sessions

5.2.  Performing five laboratorial experimental sessions. To this component a final mark, NL, is attributed.

5.2. Online components that could be questions problem solving, simulation or conceiving a lesson.


6.   Exams
Two final exams. The exams consist of two parts: a theoretical part and a problem solving part where consultation is allowed. To this component a final mark, NE, is attributed. 

7. Assessment rules

7.1. Admission to final exam

 7.1.1. Students without previous attendanceThe access to final exam is according with the following conditions: Laboratory mark, NL10

7.1.2. Students with previous attendanceAutomatically admitted to exam

7.2. Course approval and mark

N =0,7 NL+O,3 NE , N ≥10 and NE8 .  

8.Final mark, NF
NF = N
9. Scales and rounding

All the marks are given within the scale from 0 to 20. The marks of each component are given up to the first decimal point and the final mark is and integer.
