Evaluando y aprendiendo: Feedback en los procesos de evaluación

[SPA] El objetivo del estudio fue analizar el repaso grupal del examen como herramienta de autoevaluación-aprendizaje. El estudio fue realizado en Nutrición Animal-Grado en Veterinaria. Tras un examen, se procedió a explicar las respuestas, con o sin apoyo de recursos multimedia. Antes y después de la corrección del examen, los estudiantes estimaron su calificación para evaluar las correlaciones con la nota real. Se realizó un cuestionario de 5 preguntas, valoradas de 1-5. Los aspectos más destacados fueron: herramienta de autoevaluación (4.58), instrumento de aclaración (4.48) y metodología de aprendizaje (4.29). La percepción en los estudiantes que recibieron explicaciones con soporte multimedia no fue diferente del control (p=0.150). Las correlaciones entre la calificación final y las estimaciones de la nota a priori y posteriori del repaso del examen fueron 0.37 y 0.77, respectivamente. El procedimiento de revisar un examen es valorado como técnica de autoevaluación-aprendizaje, y mejora la correspondencia entre las valoraciones. [ENG] The aim of the study was to analyze the review of an exam as a tool for self-assessment/learning. The study was conducted in the subject Animal Nutrition-Veterinary Degree. After an exam, the professor explained the answers, with or without the support of multimedia resources. Before and after the correction of the exam, students estimated theirs grades to assess the correlation with the final score. A 5-question survey was performed, using a 5-point scale. The most valued aspects were: self-assessment tool (4.58), mean for clarification (4.48), and learning methodology (4.29). There were not statistical differences between the students that received explanations supported by multimedia resources and the control (p=0.150). The correlations between the final grade and the a priori and a posteriori estimates were 0.37 and 0.77, respectively. The process of reviewing immediately an exam is understood as a self-evaluation/learning technique, improving the correspondence between the scores of students and professors

EXANET: Herramienta para fomentar el aprendizaje autónomo y auto-evaluación en contextos presenciales y virtuales

[SPA]El objetivo del trabajo es presentar y evaluar la herramienta EXANET del módulo docente en la plataforma de campus virtual de la Universidad de Murcia (SUMA 2.0). Dicha herramienta ha sido utilizada durante el desarrollo de las sesiones prácticas de la asignatura Nutrición Animal de la Licenciatura de Veterinaria durante los cursos académicos 2009/2010 y 2010/2011. Exanet ha sido utilizado como herramienta complementaria y de apoyo para fomentar el aprendizaje autónomo de los alumnos, y proporcionar información sobre sus progresos para preparar la evaluación del módulo de prácticas del primer y segundo cuatrimestre. Se han diseñado un total de 18 pruebas de auto-evaluación a partir de una base de datos de preguntas para cada bloque de contenidos (análisis químicos, microscopía de piensos, valoración nutritiva y legislación, formulación y alimentación práctica). Cada prueba constaba de 10 preguntas y era de carácter mixto, con preguntas tipo test y de emparejamiento de términos, además de la inclusión de imágenes. En la configuración de las pruebas virtuales, se especificó el inicio y tiempo máximo de resolución de cada examen, con la posibilidad de su corrección inmediata y su repetición tras dicha corrección. La herramienta ha sido utilizada por más del 90% de los alumnos en prácticas, accediendo una media de 3 veces por prueba. Los alumnos han valorado la incorporación de la herramienta de auto-evaluación como buena (49%) o muy buena (47%), y más del 20% no ha encontrado ningún inconveniente para su realización. Los resultados nos indican que EXANET ha sido una experiencia de innovación educativa válida y positiva. [ENG]The aim of this paper is to present and evaluate EXANET as a tool in the Virtual Campus of the University of Murcia (SUMA 2.0). This tool has been used for the practical sessions in the subject “Animal Nutrition” of the Veterinary Medicine degree during the academic years 2009/2010 and 2010/2011. EXANET has been used as a complement and support to encourage independent student learning, and to provide information about the progress in preparing the assessment of the practical sessions of the first and second term. We have designed a total of 18 self-assessment tests from a database of questions designed for each block of content (chemical analysis, feed microscopy, nutritive evaluation and legislation, feed formulation and practical feeding). Each test consisted of 10 questions, which could be multiple choice, matching words, or image identification. In the configuration of each virtual test was specified the start time and maximum resolution time, with the possibility of immediate correction and repetition after correction. The tool has been used by more than 90% of students, and, on average, they performed 3 times each test. Students have appreciated the inclusion of this self-assessment tool as good (49%) or very good (47%), and more than 20% of them did not find any drawback to its implementation. The results indicate that EXANET has been an innovative and positive educational experience.Campus Mare Nostrum, Universidad Politécnica de Cartagena, Universidad de Murcia, Región de Murci

Stellar tidal streams are the result of tidal interactions between a central galaxy and lower mass systems such as satellite galaxies or globular clusters. For the Local Group, many diffuse substructures have been identified and their link to the galaxy evolution has been traced. However, it cannot simply be assumed that the Milky Way or M 31 are representative of their galaxy class. Thus, a larger sample of analogue galaxies beyond the Local Group is required to bolster a broader generalisation of the underlying theory. Aims. We want to detect and photometrically characterise stellar streams around Milky Way (MW-) analogues in the local Universe in order to extend the observational evidence of interactions between this class of host galaxies and their satellites. This information will be applicable in a more general context around future studies on galaxy formation and evolution processes. Methods. In the present work, we identified and analysed stellar tidal streams around MW-analogue galaxies from the SAGA sample, using deep images of the DESI Legacy Imaging Surveys. For this sample, we obtained a range of r-band surface brightness limit between 27.8 and 29 mag arcsec^(−2) . We measured the surface brightness and colours of the detected streams using GNU Astronomy Utilities software. Results. We identified 16 new stellar tidal streams around MW-analogue galaxies at distances between 25 and 40 Mpc. In applying a statistical analysis to our findings for the SAGA II galaxy sample, we obtained a frequency of 12.2% ± 2.4% for these stellar streams. We measured the surface brightness and colours of the detected streams and carried out a comparison to the dwarf satellite galaxies population around galaxies belonging to the same SAGA sample. We show that the mean colour of the streams is 0.20 mag redder than that of the SAGA satellites; in addition, the streams are, on average, 0.057 ± 0.021 mag redder that their progenitor (for cases where a likely progenitor could be identified). Conclusions. The frequency of streams detected around MW-analogues in the Local Universe is in agreement with previous studies. The difference in colour between detected streams and satellites within the SAGA host galaxy sample could be explained by a combination of both selection biases in the SAGA study and physical processes.Depto. de Física de la Tierra y AstrofísicaFac. de Ciencias FísicasTRUETalentia Senior Program (through the incentive ASE-136) from Secretaría General de Universidades, Investigación y Tecnología, de la Junta de AndalucíaCentro de Excelencia Severo OchoaMinisterio de Ciencia, Innovación y Universidades (MCIU)Ministerio de Economía y Competitividad (MINECO)CAM-UCMSpanish postdoctoral fellowshipTaiwan Ministry of Education Yushan FellowshipTaiwan National Science and Technology CouncilJapanese MEXT scholarshipEuropean Research Council (ERC)European Union - NextGeneration through the Recovery and Resilience Facility projectInstituto de Astrofísica de Andalucíapu

Changes in a Comprehensive Profile of Saliva Analytes in Fattening Pigs during a Complete Productive Cycle : A Longitudinal Study

The aim of this study was to evaluate whether a panel of 29 salivary biomarkers of stress, immunity, inflammation, redox homeostasis and other physiological functions can change in healthy fattening pigs when monitoring the different phases of their productive cycle and can be influenced by various sources of variations such as gender and performance parameters. Several analytes showed changes due to the productive cycle, with a majority of the analytes showing higher values at lactation and at the beginning of nursery. Additionally, differences were seen due to sex. These differences can be related in some cases with performance parameters and should be taken into consideration for an appropriate interpretation of the analytes. A comprehensive panel of 29 salivary analytes was measured in fattening pigs to evaluate its possible changes along their productive cycle. The identification of those changes would allow a better interpretation of the results according to the productive phase of the animal. Saliva samples were obtained from 49 Large-White pigs (24 females, 25 males) in suckling phase, at the beginning and the end of the nursery phase, and at the beginning and the end of the growing phase. Several analytes changed according to the phase of the productive cycle, with most of the analytes showing higher values at lactation and at the beginning of nursery. Additionally, differences were seen due to sex. When possible relations between performance parameters and analytes were evaluated, significant positive but weak relationships were found between weight at birth and salivary γ-glutamyl transferase, and between back-fat thickness and salivary lactate dehydrogenase. In conclusion, differences in the values of salivary analytes can be found in fattening pigs depending on the productive phase and sex of the animals
