Methodologies
Methodologies Description
Introductory activities Activities to be carried out before starting the process of teaching and learning in order to know the skills, interests and / or motivation of the students in order to achieve the objectives.

Their goal is to obtain relevant information that would allow the teaching to foster efficient and meaningful learning from the students' prior knowledge.
Guest lecture / keynote speech This methodology has to do with the foundations of knowledge of the subject specified in the contents.

In these classes, the students have a receptive aptitude following the presentations by supporting drawings on the blackboard, screen projections and digital tools (ICT).

Students take notes and ask questions about the issues raised. It aims to develop the lessons, providing both concepts and the necessary tools for their understanding from a perspective in which the architecture is always present.
Workshop This is where the student participates actively in the learning process, facing the need to assess, respond and experience all the knowledge of the lectures, to which must conform.

There are two types of exercises:
1. Drawing exercises on the board with a dedication of a practice session.
2. Special exercises as a control of the student´s learning process. A theory part could be included.

Architectural models of prestigious architects are selected for the development of these graphic exercises, whose formalization processes are clear and definable, in order that the students achieve an architectural culture.

All exercises are mandatory and should be submitted in the workshop session, every week.
Practical test: A final test will be done to all those students who in spite of attending the course did not pass the subject. It may consist of theoretical and practical contents.
Collaborative learning Individual or group work that students must develop in CAD.

Face-to-face hours will be devoted to the formulation of work, a series of lectures and the review of the works, individually or in group.

This methodology referred primarily to learning the "how to do things" to promote independent learning of students, under the tutelage of a professor.

Description
The subject is conceived eminently experimental and practical as the student's learning process is based on the realization of graphic exercises that enable the student to participate in a more personalized relationship with the teacher.

Exercises will be developed individually or in small groups and will be related to course work.

In order to achieve the objectives set, tutorial attendance is considered essential.

Practical test: A1 A2 A3 A4 A5 A6 A10 B4 B5 B12 C6 C7 Continuous assessment is applied:
-weekly drawing exercises (35%)
-special exercises (50%). A minimum arithmetic mean of 5 is needed
-collaborative CAD work (15%)

FIRST OPPORTUNITY (JANUARY)

An exam will be held for those students who do not pass the first opportunity in spite of taking part in the course or do not have a minimum mean of 5 in the special exercises. In this case the student could sit only the failed part. Theory and pracical contents could be included in the exam. All students must meet the following requirements: minimum attendance of 80% and submission of all weekly exercises and CAD work. The score of the objective test to pass the subject will be of 5/10. The final grade will take into account the objective test and the student´s work during the academic year.

SECOND OPPORTUNITY (JUNE-JULY)

An exam will be held for those students who do not pass the first opportunity in spite of taking part in the course. Theory and pracical contents could be included in the exam. All students must meet the following requirements: minimum attendance of 80% and submission of all weekly exercises and CAD work. The score of the objective test to pass the subject will be of 5/10. The final grade will take into account the objective test and the student´s work during the academic year to some extent.

Assessment comments

In order to pass the course in the 1st opportunity and / or 2nd opportunity those students who, in a justified way, can not meet 80% of attendance and deliveries of supervised practices and works, the teacher will define in a particularized way the conditions of evaluation.

Special procedures for part time students are not considered, due to the attendance to workshop is basic.

Academic leave is not considered for the same reasons.

The detection of plagiarism, as well as the fraudulent performance of tests or evaluation activities, once verified, will directly imply the grade "0" in the subject in the corresponding call, thus invalidating any grade obtained in all evaluation activities.
