Methodologies Description
Mixed objective/subjective test At the end of the programme, an exam consisting of short answer and/or test-type questionnaire will be conducted.
Guest lecture / keynote speech The professors will introduce the programme contents with the aid of multimedia stuff. They will answer the questions raised by the students.
ICT practicals Practical with computers about searching for toxicological information in internet.
Supervised projects Supervised projects in groups of students about an issue proposed by the professor. Personalized attention will be given in order to provide orientation on the contents to be included in each project. The files corresponding to each project and its presentation will be delivered through Moodle before the deadline fixed. Later on, all projects will be available in Moodle.
Seminar Bibliographic seminars: students will present their projects. Then a debate on the topic of their presentation will be conducted.
Laboratory practice Laboratory practices to be carried out in Hospital Oncolóxico laboratories. Students will learn several methodologies for genetic damage assessment.

Personalized attention
Supervised projects
Part-time students: materials used in lectures, and any other useful material, will be available in Moodle . Deadlines for supervised projects and questionnaires will be the same than for regular students, and will be specified in Moodle.

Students not attending lab or computer practices must complete a questionnaire and submit it by Moodle before the established deadline.

Upon students' request, personalized attention will be provided in order to give orientation on the contents to be included in each project, to answer questions, and to provide with help for developing specific and transversal study programme competencies.

Methodologies Competencies Description Qualification
Mixed objective/subjective test A12 A6 B5 B3 C1 Exam: short answer and/or test-type questionnaire. For the students not attending the lectures due to attendance exemption, this questionnaire will represent 60% of the final qualification. Passing this exam is mandatory to pass the whole subject. All mandatory tasks must be delivered in order to pass this subject. 40
ICT practicals B3 C2 C6 Mandatory attendance, excepting for blended students. These students must deliver a questionnaire on the activities conducted during the practical. 2.5
Guest lecture / keynote speech A6 A8 A12 Regular attendance and participation will be evaluated, only when the student pass the exam. 10
Laboratory practice A8 A12 B3 B6 C6 Mandatory attendance, excepting for blended students. These students must deliver a questionnaire on the activities conducted during the practical. 2.5
Supervised projects A12 B3 B5 B6 B9 C1 C2 It is mandatory to carry out a supervised project in group (if there are enough students). The qualification will be the same for all group members. It will be evaluated only when the student pass the exam. 40
Seminar B3 B5 B6 B9 C1 Regular attendance and participation will be evaluated, only when the student pass the exam. 5
Assessment comments

Second oportunity evaluation: students must deliver and present a supervised project (in case they had not did it before) and do the exam. Moreover, if students did not attend the mandatory attendance practices, they must deliver a questionnaire on activities addressed in those practices.
