Estudio de caso múltiple con historias de vida en el grado de educación infantil: aprendizaje-servicio en la didáctica de la educación física
2015
Este trabajo recoge un estudio sobre la aplicación del Aprendizaje-Servicio (APS) en el área de Educación Física del Grado de Maestro de Educación Infantil. Concretamente, emplea las Historias de Vida como herramienta de investigación cualitativa para conocer el perfil básico del alumnado, así como para profundizar sobre el desarrollo de habilidades sociales y valores ético-cívicos. El trabajo muestra así la adecuación de las Historias Vida como herramienta para valorar la influencia del APS en el alumnado, en tanto que los resultados obtenidos permiten conocer y ahondar sobre determinados rasgos de su personalidad, su contexto familiar y profesional, y los aprendizajes y desarrollo persona…
Innovative Analysis of Service-Learning Effects in Physical Education: A Mixed-Methods Approach
2020
Purpose: To compare the development of teaching competency in preservice teachers of physical education (n = 96) through two different modalities of intervention from the same service-learning program. The preservice teachers provided a direct service to children with motor functional diversity, promoting their motor skills and counteracting their lack of social attention. Method: The topic was approached using mixed methods with methodological triangulation. Quantitative evidence was gathered through a quasi-experimental design of two nonequivalent experimental groups implementing the following instrument: the Teaching Competency while performing Motor Skills and Body Language Games Rubric…
Maternal investment in relation to sex ratio and offspring number in a small mammal – a case for Trivers and Willard theory?
2009
1. Optimal parental sex allocation depends on the balance between the costs of investing into sons vs. daughters and the benefits calculated as fitness returns. The outcome of this equation varies with the life history of the species, as well as the state of the individual and the quality of the environment. 2. We studied maternal allocation and subsequent fecundity costs of bank voles, Myodes glareolus, by manipulating both the postnatal sex ratio (all-male/all-female litters) and the quality of rearing environment (through manipulation of litter size by -2/+2 pups) of their offspring in a laboratory setting. 3. We found that mothers clearly biased their allocation to female rather than ma…
The role of fish life histories in allometrically scaled food‐web dynamics
2019
Body size determines key ecological and evolutionary processes of organisms. Therefore, organisms undergo extensive shifts in resources, competitors, and predators as they grow in body size. While empirical and theoretical evidence show that these size‐dependent ontogenetic shifts vastly influence the structure and dynamics of populations, theory on how those ontogenetic shifts affect the structure and dynamics of ecological networks is still virtually absent. Here, we expand the Allometric Trophic Network (ATN) theory in the context of aquatic food webs to incorporate size‐structure in the population dynamics of fish species. We do this by modifying a food web generating algorithm, the nic…
