Basic skills
CB7 - The students should know how to apply the acquired knowledge and their ability to solve problems in new or little-known environments within broader (or multidisciplinary) contexts related to their area of study.
General skills
CB1 - Ability to efficiently manage information from different sources for the production of cultural knowledge.
CB4 - Acquisition of skills and work habits that enable self-learning and promote continuous training (education throughout life, according to UNESCO guidelines) .
Specific skills
CE1 - Knowledge of the operation of new ways of transmitting information, accessing it and acquiring it.
CE19 - Knowledge of research methodology and practice in all areas related to the management of cultural assets.
Knowledge and skills will be obtained through:
• Masterclasses for expository teaching fundamentally through power point . These presentations will be provided to students through the virtual campus. (Skills worked: CE1, CE19 )
It is possible to attend the classroom sessions physically or through synchronous connection to the Microsoft Teams platform.
• Interactive teaching will also be taught from the realization of different cases and practical applications. For this, the student will have video tutorials and tutorials. The use of methodologies and techniques seen in the theory will be carried out, with application to specific examples. The practices will be carried out mainly through photogrammetry initiation software, some of them specifically designed for 3D scanning by the general public and for professionals related to heritage management (Scann3D, 3DF Zepyr, VisualSFM, Meshlab). Professional software such as Metashape will also be used (Skills worked: CB7, CB1, CB4).
- The tutorials of the subject will be done through Microsoft Teams or in person according to the timetable published by the teacher.
The delivery of a final report of practices is compulsory. The lack of delivery of this work will be cause not to pass the subject. The approved practices will be saved for successive calls.
• Participation in the virtual classroom (personal anotations, tutorials, chats, forums and debates, and other virtual tools): 10%
• Work delivered and/or presented in classroom: 70% (competences CB1, CB4)
• Exam: 20% (competences CE1, CE19)
The subject can be passed without attending the final exam, which will be in person, on the day and time specified in the official calendar of exams, both in first and second opportunity.
The described evaluation system will be the one used in both the ordinary and extraordinary recovery opportunities.
Students who have been granted a waiver of attendance at any of the teaching activities scheduled in accordance with the provisions of Instruction 1/2017 of the General Secretariat, may study the subject using the material resources provided by the teacher on the virtual campus. They must carry out the practices autonomously and deliver the final memory. The work on the subject will have to be done individually. In these cases, the exam would account for the 30% of the mark, and the works for the 70%.
Face-to-face activity: presentation of basic content and practical classes: 7 hours
Face-to-face activity: tutoring to guide theoretical-methodological topics: 5 hours
Face-to-face activity: evaluation activities: 3 hours
Total hours of classroom work: 15 hours
Student's personal work:
Virtual learning and personal study: 40 hours
Preparation of works: 14 hours
Preparation of the final exam: 6 hours
Total hours of the student's personal work: 60 hours
Active class interaction by raising questions and concerns.
For cases of fraudulent performance of exercises or tests, the provisions of the "Normativa de avaliación do rendemento académico dos estudantes e de revisión das cualificacións" "(artigo 16 da Resolución de 15/6/2011 da USC, DOG de 21/7/2011)" will apply.
