Rasch Analysis of Authentic Evaluation of Young Children's Functioning in Classroom Routines.

2021

This study evaluated the functioning of children in early childhood education classroom routines, using the 3M Functioning in Preschool Routines Scale. A total of 366 children aged 36 to 70 months and 22 teachers from six early childhood education centers in Spain participated in the study. The authors used the Rasch model to determine the item fit and the difficulty of the items in relation to children's ability levels in this age range. The Rasch Differential Item Functioning (DIF) analysis by child age groups showed that the item difficulty differed according to the children's age and according to their levels of competence. The results of this study supported the reliability and validit…

Finnish Pre-Service Teachers’ Perceptions of Perceived Competence in Early Childhood Physical Education

2021

Early childhood education and care (ECEC) teachers have a central role in supporting young children’s physical activity (PA) and overall development in the early years. However, the value of early childhood education teacher training (ECETT) programmes is not widely understood. This study aimed to investigate pre-service teachers’ perceptions of perceived competence when (1) supporting a child’s PA, (2) teaching PE, and (3) observing and assessing a child’s motor skills and PA. These self-evaluations were compared with a range of individual, educational, and behavioural characteristics. Final-year Bachelor degree pre-service teachers (n = 274

The Ecology of Ostracoda Across Levels of Biological Organisation from Individual to Ecosystem

2012

Abstract Palaeoenvironmental and palaeoclimatic applications of fossil ostracods rely on a uniformitarian approach underpinned by knowledge of the biology and ecology of living species. This review reveals that in recent decades, major advances have been made in the understanding of species’ abiotic niches in relation to their preferences for different water chemistries and temperatures. However, the underlying ecophysiological mechanisms for such preferences are still largely unknown. Only a few works analyse in detail aspects of population growth or species interactions (competition, predation) in the framework of classical ecological theories. Similarly, the role of Ostracoda in the asse…

Interspecific Social Learning: Novel Preference Can Be Acquired from a Competing Species

2007

SummaryNongenetic transmission of behavioral traits via social learning allows local traditions in humans, and, controversially, in other animals [1–4]. Social learning is usually studied as an intraspecific phenomenon (but see [5–7]). However, other species with some overlap in ecology can be more than merely potential competitors: prior settlement and longer residence can render them preferable sources of information [8]. Socially induced acquisition of choices or preferences capitalizes upon the knowledge of presumably better-informed individuals [9] and should be adaptive under many natural circumstances [10, 11]. Here we show with a field experiment that females of two migrant flycatch…

Ocean acidification through the lens of ecological theory

2015

© 2015 by the Ecological Society of America. Ocean acidification, chemical changes to the carbonate system of seawater, is emerging as a key environmental challenge accompanying global warming and other humaninduced perturbations. Considerable research seeks to define the scope and character of potential outcomes from this phenomenon, but a crucial impediment persists. Ecological theory, despite its power and utility, has been only peripherally applied to the problem. Here we sketch in broad strokes several areas where fundamental principles of ecology have the capacity to generate insight into ocean acidification's consequences. We focus on conceptual models that, when considered in the co…

Shape and size in phytoplankton ecology: do they matter?

2007

This paper summarises the outcomes of the 14th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP). The authors mostly addressed their contributions on the following topics: morphological and morpho-functional descriptors of phytoplankton, size and shape structure of phytoplankton related to different kinds of environmental variables and the role of morphological and physiological plasticity of phytoplankton in maintaining the (apparently) same populations under different environmental conditions. Case studies from different kinds of aquatic environments (deep and shallow lakes, reservoirs with different age, purpose and trophic state, floodplain wetlands m…

Challenging fear: chemical alarm signals are not causing morphology changes in crucian carp (Carassius carassius)

2010

Published version of an article in the journal: Environmental Biology of Fishes. Also available at SpringerLink: http://dx.doi.org/10.1007/s10641-010-9707-9 Crucian carp develops a deep body in the presence of chemical cues from predators, which makes the fish less vulnerable to gape-limited predators. The active components originate in conspecifics eaten by predators, and are found in the filtrate of homogenised conspecific skin. Chemical alarm signals, causing fright reactions, have been the suspected inducers of such morphological changes. We improved the extraction procedure of alarm signals by collecting the supernatant after centrifugation of skin homogenates. This removes the minute …
