Intermanual transfer of shapes in preterm human infants from 33 to 34 + 6 weeks postconceptional age
Lejeune F Marcus L Berne-Audeoud F Streri A Debillon T Gentaz E 《Child development》2012,83(3):794-800
This study investigated the ability of preterm infants to learn an object shape with one hand and discriminate a new shape in the opposite hand (without visual control). Twenty-four preterm infants between 33 and 34 + 6 gestational weeks received a tactile habituation task with either their right or left hand followed by a tactile discrimination task in the opposite hand. The results confirmed that habituation occurred for both shapes and both hands. Infants subsequently held the novel shape longer in the opposite hand. The results reveal that preterm infants are capable of intermanual transfer of shape information. In spite of the immaturity of the corpus callosum in preterm infants, its development seems to be sufficient to allow some transfer of information between both hands. 相似文献

This study explores the educational achievement of immigrant youth in Spain employing data from 3 waves of the Longitudinal Study of Families and Childhood (Pànel de Famílies i Infància), a representative sample of children in Catalonia first interviewed at ages 13-16 in 2006 (N = 2,710). Results suggest consistent disadvantage in achievement among first-generation students. Differences in achievement between the second and third generations are apparent in bivariate analyses, but are explained by observable characteristics in multivariate analyses. Gender-specific analyses uncover a large achievement gap between first-generation girls and their third-generation counterparts, but no equivalent gap for boys. Region-of-origin differences are modest, with the exception of Latin American adolescents who exhibit the lowest educational outcomes. The significance of perceptions about school on achievement are discussed. 相似文献

This paper focuses on the views of 16–17-year-old science students from England, Germany, Hong Kong and Sweden on whale hunting, and their perceptions of the views of their international counterparts. The students were all provided with the same decision-making task, discussed the issue in small groups and then presented their views on video, which were shared with their counterparts. The findings show that the decision-making task served to deepen and modify students' views across all nationalities, and the students generally valued and learned from the sharing of views with students of the same age from around the world. However, an important discovery was that the German students' opinions often ran counter to those from the other 3 locations, and the paper cautions against making broad-sweeping generalisations about students' views on socioscientific issues. 相似文献

Science has a role to play in the resolution of many of the issues deemed controversial in all societies. However, evidence of a lack of public confidence in science and scientists as effective problem‐solvers continues to accumulate. This paper speculates that this lack of confidence might in part be due to the way in which science educators present controversial issues. In particular, we argue that current approaches to teaching about controversy do not sufficiently acknowledge the nature of the issues themselves. The paper proposes a set of principles as the basis for a reconceptualization of the teaching of controversial issues and gives an example of how they might be applied. 相似文献

In this study we sought to understand factors that shaped teachers’ use of student inquiry projects. We examined, over 3 years, the practices and conceptions of two teachers involved in implementing student inquiry projects. Neither teacher was initially satisfied with her success at supporting student inquiry, but the two had very different responses to difficulties they faced. These responses related strongly to their ideas about how learning should be structured. There was less relation between their stated views about the nature of science and their use of inquiry than was expected. The teacher with espoused views about the nature of science generally in accord with reform documents did not support student inquiry projects that involved actual investigations. The teacher with views on the nature of science less aligned with reform documents worked hard to support student investigations in her classroom. Our findings support the claim that merely learning about the nature of science or about student inquiry may not generate changes in a teacher’s practice. On closer analysis, we found that the two teachers understood aspects of the nature of science from two quite different perspectives, the proximal and the distal. The proximal view of the nature of science was more closely aligned with implementation of actual student investigations. The efforts of these two teachers in implementing inquiry illustrate the dilemmas and challenges they faced as they attempted student inquiry projects. 相似文献

ResumenLos datos lingüísticos fueron registrados mediante un vídeo en un contexto natural y habitual del niño. Se analiza el lenguaje desde los tres planos lingüísticos, sintáctico, semántico y pragmático. Además, para observar el nivel de desarrollo lingüístico, se comparó la producción del lenguaje del sujeto estudiado con la de otro niño cuyo desarrollo es adecuado.Tras los resultados obtenidos del trabajo, se puede concluir que los factores externos, en los aspectos que están relacionados a pautas de cuidado y de interacción diádica adulto-niño, son fundamentales para la adecuada adquisición y desarrollo lingüístico y, además, la rehabilitación del mismo no es muy esperanzadora. 相似文献

The Open University has developed an array of tutorial and advisory services for its students over 16 years. These have been reviewed regularly for their academic appropriateness and effectiveness. More recently, urgent reductions in services have taken place, in response to financial restraints. During 1985, Mary Thorpe and colleagues in the Student Research Centre, the Institute of Educational Technology conducted in‐depth interviews with students and staff to explore their perceptions of studying with the Open University. 相似文献

Online interactive systems offer the beguiling prospect of an improved environment for learning at minimum extra cost. We have developed online interactive tutorials that adapt the learning environment to the current learning status of each individual student. These Adaptive Tutorials (ATs) modify the tasks given to each student according to their previous responses. Feedback, assessment and remediation are also adapted. Over a three-year period we progressively blended ATs into notoriously challenging courses in introductory Engineering Mechanics. We assessed the impact of this initiative by reviewing three lines of data: (i) the built-in diagnostics of the system, (ii) changes in student grades from year-to-year and (iii) supplementary surveys. Generally, students liked the new blended system and grades improved. Detailed analysis revealed nuances in the measures of student learning, such as differences between high-performing and low-performing students. With these insights we are able to further adapt the system to meet the learning needs of our students. 相似文献
