Sickness presenteeism of German teachers: prevalence and influencing factors

The aim of the present study was to investigate teachers’ sickness presenteeism (SP). We examined the prevalence of SP in a sample of teachers as well as work-related and health-related influencing factors of teachers’ SP. We used a cross-sectional study design. Teachers working at different types of schools in Rhineland-Palatinate (Germany) participated in an online survey. We used Pearson’s Chi-squared test (in case of categorical variables) or Mann–Whitney-U-test (in case of continuous variables) to test for differences between SP and sociodemographic/work-related/health-related factors. Factors influencing SP were identified using multivariable logistic regression analyses. Nine hundred and twenty-four teachers working at 42 different schools completed the questionnaire (response proportion: 50.1%). The prevalence of SP in our study was 57.1%. The multivariable logistic regression analyses showed less support by supervisors (aOR: 1.77; 95-CI: 1.21–2.60), inappropriate administration efforts (aOR: 1.56; 95-CI: 1.16–2.11), and inappropriate recognition of performance (aOR: 1.44; 95-CI: 1.04–198) as well as exhaustion/fatigue (aOR: 2.29; 95-CI: 1.71–3.08) as main predictors of teachers’ SP. SP is widespread among teachers. As SP is associated with impairment of psychological and physical health in the long run, it is important to implement measures to reduce SP. A climate of support and cooperation as well as assistance for ill teachers to deal with work missed due to absence might be useful strategies.     

Shape recognition in infancy: visual integration of sequential information

To investigate the integration of visual information across space and time, infants watched the contour of a shape being traced out by a moving point source of light and then viewed 2 objects: 1 with the shape they had just seen traced and 1 with a novel shape. In the first study, which varied the number of tracings (velocity about 16.7 cm/sec), 12-month-olds looked longer at the novel object in all conditions, indicating that they recognized the similarity between the alternative object and tracing of like contour. Study 2, which varied velocity (14.7 and 7.4 cm/sec), stimuli, and the number of tracings, provided evidence for the generalizability of these results but indicated that performance suffered at the slower speed. Studies 3 and 4 held velocity constant (14.7 cm/sec) while varying the size of the tracings and age of the infant: 12-month-olds, but not 6-month-olds, recognized figures in instances where it took up to 10 sec to complete a single tracing. Because it took so long to complete many of the tracings, central rather than purely retinal mechanisms appear to be involved in integrating shape in these situations.     

Visual Learning and the Brain: Implications for Dyslexia

ABSTRACT— The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.     

Constraints on conceptual development: a case study of the acquisition of folkbiological and folksociological knowledge in Madagascar

How different are the concepts held by children who grow up in a North American middle class neighborhood and by children who grow up in a rural Malagasy fishing village? By probing Malagasy children's and adults' conceptual representations of human and animal kind, biological inheritance, innate potential and family relations, the studies presented in this Monograph address current debates about the acquisition and the nature of concepts in the domains of folkbiology and folksociology. Cross-cultural and developmental studies of this kind bear on the hypothesis that conceptual development in these domains is supported and constrained by innate conceptual content. If so, one would expect cross-cultural universality in the relevant adult concepts and their early emergence in childhood regardless of widely different input conditions. We chose to conduct these studies among the Vezo of Madagascar because the ethnographic literature has attributed to them folkbiological and folksociological theories that are radically different, even in commensurable, with those of North American adults. Vezo therefore provide a challenging test for the innate conceptual constraints hypothesis.Four studies probed aspects of biological and sociological reasoning of Vezo children, adolescents and adults through a number of adoption scenarios. Despite ethnographic reports to the contrary, we found cross-cultural convergence in adult concepts of biological inheritance, but the pattern of development of this concept differed greatly from that seen in North America. Moreover, in agreement with the ethnographic literature, we found that Vezo adults have constructed a distinctive theory of social group identity. However, we found that children's reasoning in this domain is under the influence of endogenous constraints that are overturned in the course of development. Finally, we found cross-cultural convergence in adults' concept of species kind, as well as evidence for the early emergence of this concept. In light of these findings, we discuss the nature of the constraints on children's conceptual representations, the developmental process through which the adults' concepts are constructed, and relations between Vezotheories of folkbiology and folksociology.     

Keiyo Cattle Raiding, Kechui Mathematics and Science Education: What do They Have in Common?

In the context of globalization, indigenous educational systems of endangered cultures are faced with extinction. Biologists recognize that biodiversity is dependent upon sustaining and promoting knowledge and values of indigenous cultures. Education researchers have a similar responsibility — to promulgate educational diversity before several thousand years of valuable educational knowledge is extirpated. This paper presents the Keiyo of Kenya who have a rich educational system. Its focus is on an indigenous game, Kechui (using calculations to sharpen your mind), based on cattle raiding, and the Keiyos' use of the game for learning mixed strategy-based probabilistic problem solving. Kechui may also have international potential for teaching probabilistic problem solving in contemporary mathematics and science, especially genetics.     

Special and mainstream school collaboration for the promotion of inclusion

The Green Paper Excellence for All Children ( DfEE, 1997 ) set out an agenda for the future of special needs provision which was further endorsed by Meeting Special Educational Needs: A Programme for Action ( DfEE, 1998 ). Amongst the recommendations made within these documents was a reappraisal of the role of special schools to support increased opportunities for inclusion. This paper reports on research conducted in one English local education authority (LEA) to examine an approach to develop greater links between a special school and a number of mainstream schools, with the intention of enabling pupils with complex needs to be supported in mainstream classrooms. The research focused upon the procedures which had been developed to support pupils through a period of transition from segregated to mainstream education, and considered those conditions which had been created in order that inclusion might succeed.     

Support provision for students with Special Educational Needs in Irish Primary Schools

The provision of support for students with special educational needs in schools is seen as a critical factor in the development of inclusive education. The means through which support is provided, continues to be based upon assumptions that individualized learning approaches may remediate learning difficulties. This paper reports findings from a longitudinal study of provision for students with special educational needs conducted in The Republic of Ireland. The authors identify in‐class and withdrawal approaches to support and consider the impact and efficacy of these. It is suggested that the withdrawal of students from class continues to be a dominant model, and that this approach has limitations and may not be conducive to the promotion of inclusive practice. Drawing upon data obtained through interviews with service users (students and parents/carers), and service providers (teachers, paraprofessionals, principals), and those gained from a national survey, the authors present the authentic voices of individuals to illustrate the experiences and opinions of those directly involved in special education in schools.
