Objectives

This course is part of the Bachelor's Degree in Biomedical Sciences and belongs to Module 13: Methods in Biomedicine. It is a compulsory second-year, first-semester course worth 3 ECTS credits, taught to a single class of approximately 60 students.

The course combines theoretical content with classroom practical sessions and forms part of a module primarily focused on practical and applied subjects. The aim of the Methods in Biomedicine module is to strengthen the experimental and interdisciplinary nature of Biochemistry by providing students with both the theoretical foundations of the main experimental techniques and their practical applications. Within this framework, Experimental Techniques in Biomedicine I establishes its learning objectives.

An additional feature of the course is its close integration with Experimental Techniques in Biomedicine II, which is taught during the second semester. Together, these complementary courses provide students with a comprehensive introduction to the fundamental chemical, biological and physical techniques that are essential for biomedical research.

The overall objective of the course is to provide students with a solid understanding of the main experimental techniques used in Biomedicine and their applications throughout their studies and future professional careers. Specifically, students are expected to:

  • Acquire and understand the theoretical principles underlying the main biomedical techniques.
  • Apply these techniques in biomedical research and practice.
  • Develop independent learning skills by acquiring, evaluating and critically interpreting scientific information.
  • Increase their interest in the technical and experimental aspects of biomedical research.

Learning activities and methodology

Title Hours ECTS Learning outcomes
Study 23 0.92 CM28, CM29, KM36, KM37
Seminars 8 0.32 CM28, CM29, KM36, KM37
Theory classes 18 0.72 CM28, CM29, KM36, KM37

The course includes 18 hours of lectures and 8 hours of classroom practical sessions per student. Classroom practical sessions are organised into two groups, with a total of 16 scheduled PAUL teaching hours to cover both groups.

The teaching methodology combines lectures with classroom practical sessions. In some topics, problem-solving activities will be integrated with theoretical concepts to facilitate understanding.

Classroom practical sessions focus on the analysis and critical discussion of scientific articles, experimental data and methodological situations related to the techniques covered in the course.

Depending on the needs arising during the course, tutorials may be scheduled to discuss specific aspects of the subject.

Where appropriate, active learning methodologies, such as case-based learning and critical discussion of scientific articles, will be used to promote student participation and the integration of methodological knowledge. When selecting examples and teaching materials, efforts will be made to incorporate a gender perspective and to highlight diverse contributions to biomedical research.

Note: 15 minutes of one class will be reserved, within the schedule established by the centre or degree programme, for students to complete the surveys evaluating the teaching staff and the course.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Exam of theory 2nd partial 40% 9 0.36 CM28, CM29, KM36, KM37
Exam of theory 1st partial 40% 9 0.36 CM28, CM29, KM36, KM37
Assessment of classroom practical sessions 20% 8 0.32 CM28, CM29, KM36, KM37

This course is assessed exclusively through continuous assessment. A single-assessment option is not available.

Continuous assessment

  • Continuous assessment consists of two multiple-choice tests covering the theoretical contents of the course and the assessment of the classroom practical activities (PAUL).
  • The two multiple-choice tests account for 80% of the final course grade and are eligible for reassessment. A minimum mark of 4.5 must be obtained for these tests to be averaged with the remaining assessment components.
  • Classroom practical activities (PAUL) account for the remaining 20% of the final grade. No minimum mark is required, and this component is not eligible for reassessment.
  • Students who obtain a mark of 5.0 or higher in the multiple-choice tests may not retake them to improve their grade.
  • To be eligible for reassessment of the multiple-choice tests, students must previously have completed assessment activities representing at least two-thirds (67%) of the final course grade.
  • Students will receive a grade of "Not Assessable" if the assessment activities completed account for less than 67% of the final course grade.
  • To pass the course, students must obtain an overall final grade of 5.0/10 or higher.
  • Any irregularity during an assessment activity (including academic fraud, plagiarism or the improper use of artificial intelligence tools) that may significantly affect the assessment outcome will result in a mark of 0 for that activity. In addition, the University may initiate disciplinary proceedings in accordance with its academic regulations.
