1.1. Introduction

 

Brief presentation of the subject

The subject Epidemiology and Biostatistics are of obligatory character and they is integrated by two matters given by professorship of two different areas: Epidemiology (Area of Animal Health) and Biostatistics (Area of Applied Mathematics. Also this subject presents the peculiarity of which both matters belong to different modules inside the Grade in Veterinarian: Epidemiology (Clinical Sciences and Animal Health) and Biostatistics (Common Basic training). It has a teaching load of 6 ECTS (4 Epidemiology and 2 Biostatistics) and has annual character, being given during the first course of the Grade.

The contents of these two matters are the base for a correct use of the scientific method in the context of the veterinary sciences, as well as to allow a suitable knowledge of the animal populations and of the illnesses that affect them. In case of the matter Biostatistics there develop specially the competences defined as the Order ECI/333/2008 as Biometrics and statistics applied to the veterinary sciences and Dynamics and demography of the infection and the poisoning, while the matter Epidemiology the developed competences are: Transmission and maintenance of the illnesses and methods of study of the illnesses in the populations, Diagnosis Epidemiology and diagnosis, System of pursuit and alertness, The investigation of sprouts of food toxi-infections and Dynamics and demography of the infection and the poisoning.

The subject uses a teaching platform specially designed for these matters (http://alp4eb.winepi.net/)

1.2. Recommendations to take this course

2.2. Importance of learning goals

Importance of the results of learning that are obtained of the subject

These learning results are fundamental to qualify the students of a solid base that allows them to confront in the best conditions the most specific rest of modules of character of the qualifications, and this way to shape successfully its professional profile.

Also, with the works in the practice rooms there is encouraged the strengthening of the generic or transverse competences that they contribute to its integral formation like postgraduates, especially the work in team and the use of computer hardware.

3.1. Aims of the course

 

The subject and its due results answer to the following expositions and targets:

The exposition in this subject departs from the situation of need that is created before a scientific study of realizing a correct epidemiologic and statistical analysis. The quality of the research work will be of major quality, the better and the more rigorous is the epidemiologic and statistical study that we realize.

The general target therefore is, from the experimental results and the formulation of a hypothesis, to be capable of obtaining the scientific thesis endorsed by a correct epidemiologic and statistical study.

3.2. Competences

On having overcome the subject, the student will be more competent for …

1. To make use of a scientific reasoning, with critical character, in the analysis, synthesis and evaluation of epidemiologic models and real statisticians.

2. To apply the knowledge acquired to the analysis and search of the model that better represents a set of experimental information, and to confirm properly the above mentioned solutions.

3. To use the computer applications relative to the ambience of study.

4. To use Internet as an information source, as well as mass communication media.

5. To dominate the aspects of the communication, both oral and written.

6. To show capacity of organization and autonomous planning of the work.

7. To apply appropriately the probability distributions to the different situations observed in Veterinary Sciences.

8. To understand the mechanisms of transmission and maintenance of the illness / infection in the animal populations.

9. To design, to realize and to analyze epidemiologic studies, including sampling, measurement of illness and detection of factors of risk.

4.1. Assessment tasks (description of tasks, marking system and assessment criteria)

Evaluation activities

 

The student will have to demonstrate that it has reached the results of learning foreseen by means of the following activities of evaluation

1) Evaluation of theoretical knowledge and its application to a real context: It is based on the resolution of different activities on the teaching platform of the subject (multiple answers, mails, problems…) with documentary support and of progressive form. First of all there includes activities “key“ not evaluables whose correct resolution is necessary to keep on gaining access to the activities (included theoretical cards). The activities evaluables are specific for every student and they are distributed in 20 topics with different individual weighting as its relevancy (to see Annex I) whose entire sum is proportional to the number of ECTS of every matter, so that in the final qualification the Biostatistics activities are 10% of the final qualification and the Epidemiology activities are 20% of the final qualification.

2) Evaluation of the problem solving in the practical meetings: Since in the previous case it is a question of specific problems for every student whose access can depend on the previous and obligatory resolution of activities “key“. They are distributed in 10 practices with different individual weighting as its relevancy (to see Annex II) whose entire sum is proportional to the number of ECTS of every matter, so that in the final qualification the Biostatistics activities are 6,7% of the final qualification and the Epidemiology activities are 13,3% of the final qualification.

3) Epidemiologic study: It is a question of a study based on the securing of samples of a (virtual) porcine development that provides information of quantitative and qualitative variables that will be analyzed of form integrated from the epidemiologic and biostatistical point of view applying the methods and skills learned previously. This activity is realized in the second half of the second semester with the support of two practical meetings attend them and he supposes 20% of the final qualification being necessary to obtain 50% of the maximum qualification (5 on 10) so that the continued evaluation is valid.

4) Examinations TIC attend them: In order to validate the aptitude to solve the same type of activities raised in the paragraph 1 without documentary support and descontextualizadas, the achievement appears across the platform of two examinations: one of Epidemiology and other of Biostatistics, as soon as there was finished the teaching of the theoretical topics of the subject. The final qualification is proportional to the number of ECTS of every matter, so that in the qualification of the examination of Biostatistics it is 6,7% of the final qualification and the Epidemiology examination is 13,3% of the final qualification. In both cases it is necessary to obtain 60% of the maximum qualification (6 on 10) in each of the examinations so that the continued evaluation is valid, and the repetition of the same ones is possible in case of the above mentioned punctuation is not reached. The incorrect answers do not penalize.

5) Written test: Finally in the period of achievement of complementary tests of continued evaluation (week before to the period of examinations of June - July) there will be realized by voluntary character a written test where there will be evaluated the aptitude to solve problems of reasoned form and to apply appropriately the basic theoretical concepts to the context of the raised problems. It will consist of 6 questions (2 of Biostatistics and 4 of Epidemiology) and will suppose 10% of the final qualification (3,3% Biostatistics and 6,7% Epidemiology).

6) Also there will be valued the participation in different voluntary activities that will be realized along course, so much of form presencial as not presencial: cumplimentación of the self-assessment activities before the teaching of the corresponding theoretical class, collaboration in activities in theoretical classes, assistance to voluntary seminars... According to the programmed activities every course, this punctuation increase will suppose an additional maximum of 10% to the final note.

Criteria of evaluation and levels of demand

First of all it is necessary to bear in mind that the subject is divided in two matters of knowledge (Epidemiology and Biostatistics), which as we will see have its coordinated and integrated learning activities. Nevertheless on having talked each other of matters belonging to different modules, it is necessary to guarantee that the evaluation is established so that they go to need a few minimums in every matter.

It is a continuous assessment, by what the attitudes and aptitudes are evaluated, as for the capacity of deductive reasoning, the application of the knowledge acquired in the analysis and solving of real problems. Complementarily in the activities attend them, it will be possible to appreciate and to value better the acquisition of transverse competences.

The result of the global sum of the qualifications of five activities of evaluation will have to be equal or superior to 5, but also, as it has been indicated in the previous paragraph, in the epidemiologic study TIC of both matters will have to obtain a minimal punctuation of 50% of the maximum possible qualification and of 60% in case of the examinations.

Qualifications system:

0-4,9: Failure (SS).

5,0-6,9: Pass (AP).

7,0-8,9: Notable (NT).

9,0-10: Understudy (SB).

The qualifications system will express itself by means of numerical qualification in accordance with the established in the article 5 of the Royal decree 1125/2003 of September 5 (BOE September 18), by which there is established the European system of credits and the system of qualifications in the university qualifications of official character and validity in the whole national territory.

 

Tests for students do not attend them or those that appear in other calls different from the first one

These tests affect only the students who have not realized or overcome the continued evaluation, and it will consist of the overcoming with a minimal qualification of 50% of the activities corresponding to the practical meetings (equivalent to the activity 2 of the system of continued evaluation), and that will be able to be realized of form not presencial across the teaching platform. The qualification of this test will suppose a third of the final qualification. Two remaining thirds will correspond to a written examination for every similar matter to described in the activities of continued evaluation (activity 5) (2 Biostatistics questions and 4 Epidemiology questions), which will complement with 30 type questions test (10 of Biostatistics and 20 of Epidemiology) penalizing the incorrect answers with 1 divided one by the number of incorrect options. It will be necessary to obtain at least 50% of the maximum qualification in every examination.

5.4. Course planning and calendar

Meetings calendar attend them and works presentation

The dates and key milestones of the subject are described in detail, together with those of the rest of subjects of the first course in the Veterinarian's Grade, on the Web page of the Veterinarian's faculty (linkage: http://veterinaria.unizar.es/gradoveterinaria/). The above mentioned linkage will be updated to the beginning of every academic course. Likewise it will be available in the teaching platform of the subject. The alternation between the topics of both matters and the order of some topics will be able to change according to the availability of the teachers and the teaching programming of other subjects and they will be published to beginning of course in the teaching platform of the subject.
