General description

O desenvolvemento é un proceso fascinante de autoconstrucción (e tamén de autorenovación) de todos os organismos pluricelulares a partir da condición unicelular. A materia é optativa do segundo cuadrimestre do 4º curso (8º semestre) na que se integra información e coñecementos previos tratados en cursos anteriores. Trátase do estudo das bases celulares e mecanismos moleculares implicados nos procesos do desenvolvemento ontoxénico dos seres vivos, en especial dos procesos de diferenciación e morfoxénese, facendo especial referencia ao desenvolvemento durante a embrioxénese dos metazoos.

Methodologies

Methodologies	Description
Introductory activities	This session consists of a presentation of the subject, which sets out and explains the purpose and objectives of the subject, its structure, activities, evaluation criteria, etc ... (all contained in summary in the teaching guide) and where student can solve any queries related to them.
Guest lecture / keynote speech	Lectures last 50 minutes and will focus on those relevant topics of the course program, which the student should be read before .
Directed discussion	Each seminar session will be presented and discussed among participants about a scheduled topic. Students should prepare their own theme or part of the intended subject assigned. The proffessor will assist any questions that may arise along the preparation.
Laboratory practice	The practices are an essential complement to the theoretical lessons which addresses some of the processes of animal development and elaborates on some of them.
Short answer questions	The examination shall be written and consist of short answer questions of the contents treated in lectures, seminars and practical lessons.

Personalized attention

Methodologies

Directed discussion

Description

the lecturer will assign a particular topic each student within the general theme for each seminar discussion.
Moreover, the student is free to discuss any concerns during the keynote sessions and practices, and also have the opportunity to resolve any questions about these subject or activities in personal tutorials

Assessment

Methodologies	Competencies	Description	Qualification
Short answer questions	A1	the examination will be written and consist of short answer questions, doing schemas, definitions ...	70
Directed discussion	A29 B1 B4 B6 B8 B10 B11 B13	For each seminar session the student must give the teacher a brief one-page summary including the main ideas of the subject worked. In the seminar session, the ideas in common will be discussed among participants. Both the presentation and the discussion will be valued. The 8 seminars represent the 30 percent of the final grade (each seminar is worth 0,375 points over 10). Abstracts not presented and defended in the seminar session will not be assessed.	30

Assessment comments
It is not necessary to achieve a minimum score on the topics of discussion and / or consideration for the calculation of the final grade. In the second call only the score of written exam in which knowledge derived from theoretical, practical sessions and seminars will be assessed, will be considered. Exceptionally, under justified reasons (part-time learning or particular learning circumstances), in case the student could not follow the assessment activities, the teacher can adopt appropriate measures aimed not to hurt their score. It will be considered not submitted the student who does not make the final exam based on short answer questions

Other comments
Assistance is recommended to all keynote sessions so as active participation in the seminars. It is very positive to consulted own before the issue to be addressed in the lectures so as to study throughout the course to strengthen knowledge and to better understand the new content that will be treated.
