Theory classes
In the theory classes, the teacher explains the fundamental mechanisms of the functioning of plants, referring to the processes of growth and metabolism, establishing the relationships between them and clarifying basic concepts necessary for their understanding. The methodology is mainly oral presentation with digital accompaniment. Teacher-student interaction is worked with questions, reasoning, anecdotes or any other activity that promotes teacher-student communication and gives an overview of the concepts developed in the contemporaneity of the explained syllabus. The basic bibliographic references and other sources of information are given to encourage independent study.
Seminars
The main purpose of the seminars in this subject is to promote students' knowledge of general and transversal skills. The teaching methodology is based on the presentation and discussion of case studies and/or problems posed by the teacher to the students so that they solve them in groups, present it to their peers and discuss it with them with the help and guidance of the teacher .
Practical classes
Some of the topics discussed in the theory class are visualized through an experiment in the laboratory. The student becomes familiar with protocols and basic techniques of a Plant Physiology laboratory and learns to represent and interpret the results obtained in his own experiments. The student will be able to access the protocols and practice guides through the Virtual Campus.
Tutoring
In the group tutorials, the teacher tries to resolve doubts about the concepts of the subject and guide the students in their study.
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
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| Exam | 70% | 3 | 0.12 | 7, 8, 9, 15, 11, 12, 4, 5 |
| Laboratory practices | 20% | 0.5 | 0.02 | 2, 1, 3, 10, 12, 4, 5 |
| Seminars | 10% | 0.5 | 0.02 | 17, 16, 6, 1, 10, 14, 13, 11, 12, 4, 5 |
The evaluation of the theoretical part is done through written exams that include the evaluation of the contents of the classes. There will be two eliminatory tests corresponding to each of the parts into which the syllabus is divided.
In order to pass the subject, you must achieve a minimum grade of 5 in each of these parts. The weight of each partial exam in the theory grade is 40% for the first partial exam and 60% for the second partial. The weight of the theory grade in the final grade is 70%.
To pass grades below 5, the final recovery of each of these exams must be done in a final recovery exam.
In order to improve the grade, a final exam must be taken for all content and the grade of this final exam will be counted (ie, with the waiver of the previously obtained grade)
On the last day of practice there will be a final written test individually that will represent 80% of the practice grade. The preparation of the practice script will be done in groups and will represent the remaining 20% of the grade. The script will be delivered via Virtual Campus one week after the end of the internship. The final grade of practicals represents 20% of the total grade of the subject. Attendance at practices is mandatory. In case of justified non-attendance, it can be recovered by attending another group or, if this is not possible, by means of substitute work. It is up to the teacher to assess the justification for non-attendance. There is no recupercaio of practices.
Participation in seminars and the quality of the work and/or problems solved and presented count for 10% of the final grade. Seminars are not recovered.
The subject will be approved when the student meets the conditions to be able to pass it and the grade resulting from the different parts (exams, practicals and seminar) is ≥ 5.0
It will be considered that a student will obtain the grade of Non-Evaluable when the number of assessment activities carried out is less than 50% of those scheduled for the subject (the two elimination exams, the three practice sessions and the participation in the seminars) . The presentation to the final make-up exam in any case means that the student has presented and will be evaluated
Students who cannot attend an individual assessment test for justified reasons (such as illness, death of a first-degree relative or accident) and provide the corresponding official documentation to the Degree Coordinator, will have the right to take the test in question at another date
Unique assessment:
This subject contemplates the single assessment which consists of a single synthesis test in which the contents of the entire theory program will be assessed. The test will mostly consist of questions to be developed and some relationship, test or sentence or paragraph completion questions. The grade obtained in this synthesis test will account for 70% of the final grade of the subject.
The assessment of practical activities and seminars and the delivery of assignments will follow the same process as the continuous assessment, and the grade obtained will represent 20% and 10% of the final grade of the subject respectively.
The single assessment test will coincide with the same date fixed in the calendar for the last continuous assessment test and the same recovery system will be applied.
