Contents |
Topic | Sub-topic |
I. DESCRIPTIVE BIOSTATISTICS | Biostatistics in veterinary sciences. Data organization. Calculation of Probabilities. Random variables. The normal distribution. This thematic block includes 1 practical session for solving exercises and cases, lasting 2 hours. This practical session is carried out in a computer classroom (CRAI-TIC). There will be two modules per practice and the number of teachers per group is 1. |
II. STATISTICAL INFERENCE | Introduction to statistical inference. Hypothesis contrast. Linear regression. Variance analysis. Introduction to linear models. This thematic block includes 2 practical sessions for solving exercises and cases, each lasting 2 hours (a total of 4 practical hours). These practical sessions are carried out in computer classrooms (CRAI-TIC). There will be two modules per practice and the number of teachers per group is 1. |
III. BASIC CONCEPTS AND DATA SOURCES IN EPIDEMIOLOGY | Concept of epidemiology. Historical development. Basic principles and objectives of epidemiology. Recovering and collecting information for epidemiological purposes. Surveys and questionnaires. Sampling: design and calculation of sample size. This thematic block includes 2 practical sessions for solving exercises and cases, each lasting 2 hours (a total of 4 practical hours). These practical sessions are carried out in computer classrooms (CRAI-TIC). There will be two modules per practice and the number of teachers per group is 1. |
IV. VALIDATION OF DIAGNOSTIC TESTS | Validation of diagnostic test: sensitivity and specificity. Determination of cut-off ROC curves. Predictive values and likelihood ratios. Measurement of agreement between diagnostic tests: kappa statistic. This thematic block includes 1 practical session for solving exercises and cases lasting 2 hours. This practical session is carried out in a computer classroom (CRAI-TIC). There will be two modules per practice and the number of teachers per group is 1. |
V. DESCRIPTIVE EPIDEMIOLOGY | Morbidity measures: prevalence and incidence. Demographic statistics. Spatial and temporal distribution of the disease. This thematic block includes 2 practical sessions for solving exercises and cases. One of them, lasting 2 hours, will be carried out in a computer classroom (CRAI-TIC) and the second will be a supervised PBL group work (room 9) lasting 2.5 hours (2 hours presential and half an hour to finish a report). There will be two modules per practice and the number of teachers per group is 1. |
VI. ANALYTICAL EPIDEMIOLOGY | Causes and determinants of disease. Analytical epidemiological studies. Measures of the degree of association. Errors and biases: confounding variables. Experimental epidemiological studies. This thematic block includes 3 practical sessions. Two of them, each lasting 2 hours, a total of 4 hours, will be exercises and case resolution practices and will take place in a computer classroom (CRAI-TIC). The third practical session will be a supervised PBL group work (room 9) lasting 2.5 hours (2 hours presential and half an hour to finish a report). There will be two modules per practice and the number of teachers per group is 1. |
VII. CONTROL AND ECONOMY OF THE DISEASE IN ANIMAL POPULATIONS | Main strategies for disease control in animal populations. Main tools in the economic assessment of the disease in animal populations. |

Methodologies |
Description | |
Lecture | Theoretical classes with the help of visual presentations. Students will have support material available on the institutional Moodle educational platform. Student participation in the lectures will be encouraged and evaluated, carrying out questionnaires in the classroom or voluntary presentations of some specific aspects as well as practical exercices. |
Practicals using information and communication technologies (ICTs) in computer rooms | Practical sessions for solving exercises and cases in the computer room in which practical assumptions and exercises corresponding to each thematic block are proposed. The proposed exercises will be available on the institutional Moodle educational platform before each practical session. Each student will have 9 sessions lasting 2 hours. Each practical session will be taught by 1 teacher. |
PBL (Problem Based Learning) | Practical sessions, in a classroom that allows group activities. A problem based learning or PBL exercise will be carried out. The assumptions, as well as the additional information necessary for the approach and resolution of each proposed situation, will be available, on the institutional Moodle educational platform, before each practical session. Each student will have 2 sessions lasting 2 presential hours and a group report will be generated and submitted to the responsible teacher. Each practical session will be taught by 1 teacher. |
Personal tuition | Tutorials will be carried out individually, including face-to-face and non-face-to-face sessions, through email or forums enabled on the institutional Moodle educational platform for each of the thematic blocks and practical sessions. In any case, the use of face-to-face tutorials is recommended to resolve doubts related to practical problems and PBL. |

Other comments and second call | |||
In the ordinary
call, the mixed evaluation test will count for 40% of the grade (20% evaluation of theoretical contents
and 20% evaluation of practical contents), with 60% corresponding to continuous evaluation (evaluation exercises in institutional Moodle
that will count
40% and attendance and active participation in master sessions, tutorials, ICT practices in computer classrooms and
problem-based learning sessions will count for 20%). |
