Methodologies
Methodologies Description
Guest lecture / keynote speech Exposición oral complementada co uso de medios audiovisuais e a introdución de algunhas preguntas dirixidas aos estudantes, coa finalidade de transmitir coñecementos e facilitar a aprendizaxe.
A clase maxistral é tamén coñecida como “conferencia”, “método expositivo” ou “lección maxistral”. Esta última modalidade sóese reservar a un tipo especial de lección impartida por un profesor en ocasións especiais, cun contido que supón unha elaboración orixinal e baseada no uso case exclusivo da palabra como vía de transmisión da información á audiencia.
Problem solving Técnica mediante a que se ten que resolver unha situación problemática concreta, a partir dos coñecementos que se traballaron, que pode ter máis dunha posible solución.
Laboratory practice Metodoloxía que permite que os estudantes aprendan efectivamente a través da realización de actividades de carácter práctico, tales como demostracións, exercicios, experimentos e investigacións.
Mixed objective/subjective test Exame que integra preguntas tipo de probas de ensaio, preguntas tipo de probas obxetivas así como resolución de casos e problemas.

Assessment comments
In January and July, the practical course will be evaluated in a practical exam, independent of the "Mixed test". For those that passed the practical course in January (but not other parts) the numerical note will be saved until July.

It´s necessary to pass the three parts: problems, practical course and exam independently to pass the subject.
The numerical value of the practical part is valid only in January and July.

For the final note (in January) if the sum of the notes is higher than 5 but any of the parts failed, in the final calification it will show up a 4,9 and it will be necessary to repeat this part in July.
The assistance to the practical course is mandatory.
In order to have a Non-presented, the students shouldn´t participate in more than 10% of the programmed parts.
In July it will be possible to recover the 100% of the subject value with the exams of practical course (15%) and Mixed test (85%).

Other comments
We inform that to be honored with "matrícula" the best qualifyed students in the first oportunity (January) will have preference. Drinks or food are not allowed in the classroom. To Pass succesfully the subject is necessary to pass each of the parts: Exams, practical course and Activities in reduced group. We recommend the assistence to the reduced groups and the personal tutorials to increase the student´s succes.
