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.
Student portfolio It is a folder ordered by sections, properly identified or labeled, containing the materials undertaken by the student over a period of time, with the comments and ratings made by the teacher, enabling to view the student progress.
Parts of the student portfolio:
1.- Notes taken by the student in guest or theory lectures
2.- Drawing exercises made in the workshop, including special ones that should be repeated individually in order to correct all mistakes made by the student during classroom teaching.
3.- Drawing or graphic exercises made at home. These works are mandatory and essential in order to pass the course and to sit the final test regardless first or second opportunity.

The student portfolio must be submitted together with the special exercise and will be returned to the student after being reviewed and assessed
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.

There are two types of exercises:
1. Drawing exercises on the board with a dedication of a practice session, 30%.
2. Special exercises as a control of the student´s learning process, 35%. Theory contents could be included in these special exercises.

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 they should be submitted at the end of every session.

Practical test: A1 A2 A3 A4 A5 A6 A10 B4 B5 B12 C6 C7 All students that don´t pass, in spite of attending classes, will have to sit an exam.

It may consist of practical and theoretical contents.

FIRST OPPORTUNITY (JANUARY)
Applying to students either scoring below 5 or with special exercises below 5 and observing the following conditions:
- 80% attendance and submission of all weekly exercises
- Submission of the supervised projects

SECOND CHANCE (JULY)
The same conditions as the first opportunity.

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.

Assessment comments

To overcome the subject in the 1st opportunity and / or 2nd opportunity those students who, in a justified way, can not meet 80% of assistance and deliveries of supervised practices and works, the teacher will define in a particularized way the conditions of evaluation.
