Within this subject, the aim is to contribute to the students achieving the competences set out in the USC Bachelor's Degree in Nursing:

Basic:

CB1. That students have demonstrated to possess and understand knowledge in an area of study that starts from the basis of general secondary education, and is usually at a level that, although it is supported by advanced textbooks, also includes some aspects that involve knowledge from the forefront of their field of study.
CB2. Students are able to apply their knowledge to their work or vocation in a professional manner and possess the competences usually demonstrated through the development and defence of arguments and problem solving within their field of study.
CB3. Students have the ability to gather and interpret relevant data (usually within their area of study) in order to make judgements that include reflection on relevant social, scientific or ethical issues.
CB4. Students are able to transmit information, ideas, problems and solutions to both specialist and non-specialist audiences.
CB5. That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy.

General:

CG3. Know and apply the theoretical and methodological foundations and principles of nursing.
CG6. Base nursing interventions on scientific evidence and available resources.
CG14. Establish assessment mechanisms, considering scientific-technical and quality aspects.

Transversal:

CT1. Ability to apply knowledge to practice.
CT5. Ability to solve problems.
CT7. Capacity for analysis and synthesis.
CT9. Decision-making skills.
CT14. Information management skills (ability to search for and analyse information from different sources).
CT16. Research skills.
CT17. Basic computer skills.

Specific:

CE6.Apply health care information and communication technologies and systems.

In the expository teaching sessions, the theoretical and practical concepts of the contents will be explained, supported by multimedia presentations. Some typical problems will also be solved, so that students can work on the exercise sheets that will be provided. In addition to the recommended bibliography, students will be provided with complementary teaching material. The interactive laboratory classes will take place in the computer room where students will be introduced to the use of statistical packages. In this session, students will also work on the clinical cases shared with other subjects of the course. In order to follow the practical classes, students will be provided with the syllabus. The other part of the interactive teaching will take place in the classroom and will be aimed at problem solving.

The tutorials are designed to monitor student learning.

Continuous assessment (20%): continuous assessment includes several tests throughout the course, including the resolution and delivery of practical cases proposed by the teacher. In order to be assessed, students must attend at least 75% of the interactive sessions. This qualification is retained between sessions of the same academic year.

Virtual course on Training in Information Competences in Nursing (10%).

Final exam (70%): the final exam will consist of several theoretical-practical questions on the contents of the subject, which may include the interpretation of results obtained with the statistical package used in the interactive teaching.

The weight of the continuous assessment in the extraordinary opportunity of recovery (July tests) will be the same (30%).
For cases of fraudulent performance of exercises or tests, the "Regulations for the evaluation of students' academic performance and revision of grades" will be applicable.

In this subject, students have 36 hours of classroom teaching (18 hours of lectures and 18 hours of interactive teaching). For each hour of expository teaching, it is considered necessary to dedicate around 1.5 hours of student work to study (revision of concepts and consultation of bibliography).

In relation to interactive teaching, for each hour, one hour is considered necessary for revision of the class. In addition, students should bear in mind that it is necessary to practice problem solving (from the bulletins or the recommended bibliography).

Attendance at the lectures and interactive sessions is essential to follow and pass the subject. Students must complete all the activities recommended by the lecturers (problem solving, literature review and practical exercises) in order to successfully pass the subject.

The students will have the materials of the course in the Virtual Campus (Moodle). In these materials are the contents (theoretical and practical) of the subject.
