Methodologies
Methodologies Description
Guest lecture / keynote speech A relevant fraction of the face-to-face activity uses the expository method, whose responsibility falls mainly on the teaching staff, either orally or with the addition of audiovisual media. However, and regardless of the above, during these sessions the aim is to achieve a certain quota of participation by the students, enhancing their involvement, promoting feedback on the process (and therefore the two-way nature of communication), and energizing the learning mechanisms through interaction techniques.
Problem solving There will be practical tests, designed from the previously worked content, and which must be solved in a limited time. The progressive nature of such tests obeys the criteria of continuous evaluation, so that the conclusions of each phase can serve to redirect the teaching and learning processes appropriately, adapting them to the particularities of the group in order to achieve the intended competences.
Workshop The subject participates in the 7th semester workshop, where Projects 6, Construction 5 and Urban Planning 4 are also integrated. The workshop is conceived as a work and exchange space designed to facilitate the confluence of the contents of the different subjects around the architectural project, and therefore is based on the multidisciplinary integration on the resolution of practical cases.
Diagramming It is intended that the student develop the analysis and synthesis skills during the course through the preparation of synoptic documents. In this way, an attempt is made to reinforce meaningful learning through the structured synthesis of the main contents worked on. The elaboration is understood as progressive, continuously ordering concepts and expressions, outlining analysis processes, and influencing the deduction of possible relationships between the successive themes of the program.
Mixed objective/subjective test Written tests are proposed as a diagnostic, formative and summative evaluation tool. The design adjusts in each statement to the profile of knowledge and abilities that it is intended to value, influencing the understanding of the theoretical contents and the skills associated with the analysis and resolution of practical cases.

Problem solving
Description
A learning-oriented methodology requires the consideration of the singularities that distance some students from others within the same group, in terms of previous training, possible deficiencies, attitudes and skills, expectations and motivations. For this reason, it is understood that an additional dedication is basically structured through face-to-face or virtual tutoring, the fruit of which depends largely on the level of involvement of the student. In order to facilitate the monitoring of their evolution throughout the course, at the beginning of the course they must correctly fill in the corresponding student virtual card.
Likewise, and given the progressive nature of the subject, it is advisable to solve all possible doubts as they arise, as soon as possible and using the corresponding tutorials.
This question is intensified, if possible, in the development of the projects proposed at the workshop level, whose methodology only makes sense if there is regular and periodic contact with the teaching staff in order to optimize and, where appropriate, redirect the activities in progress.
The proposed tests may be reviewed after their qualification, within the established deadlines, in order to verify the errors made and consequently serve a better formative function of the continuous evaluation processes.

Assessment comments

Assessment, as
a system for collecting information aimed at the issuance of value judgments
(and in its case of merit) on the learning process, requires continuous
development with constant student involvement. With this premise, the
attendance and participation of the student are understood as fundamental, so
that an unjustified and repetitive absence can have an unfavorable impact on
the grade obtained by the course, in a similar proportion to a lack of
participation or a negative attitude. The correction criteria include not only
the accuracy of the results, but also the clarity of the presentation, the
structuring of the analysis carried out, the use of units, the correct
application of the normative criteria, and the terminology used.

The continuous
evaluation system is configured with mixed tests (theoretical-practical exam)
that will be carried out during the school period, and workshop practice, each
of these items representing the percentage indicated above on the overall
grade.

In order to
carry out the intermediate mixed tests, the following are necessary
requirements:

· Having
delivered the student virtual card correctly within the stipulated period.

· Attendance
not less than 80% in the corresponding period, applicable in each of the
categories of face-to-face classes (expository, interactive and workshop). This
condition will not be required of students with part-time enrollment.

In order to
pass the subject per course, the following requirements must be met:

· Have
obtained in each of the intermediate mixed tests a rating of not less than 5
out of 10.

· Have
obtained a grade of not less than 1 out of 5 in the workshop exercise.

Students who
have not passed the subject per course will be retested for the pending parts (mixed
tests) in the two official opportunities of the same course. In both cases, the
grade obtained from the workshop will be kept, given that the delivery of this
exercise is unique, on the date defined for this purpose.

The students
who have passed the subject of projects 6, in order to approve structures 4,
will have to develop their workshop proposal on the subject developed in the
course in which they have passed projects 6, in any case requiring adequate
follow-up during the period of workshop teaching.

Any finding
of plagiarism or relevant breach of the conditions established for the
development of deliveries and/or exams will result in a failure grade (0) in
the matter and in the corresponding call, invalidating any assessment obtained
in all previous assessment activities, facing subsequent calls.
