Better safe than sorry? Risk and educational research     

Per Lindqvist  Ulla Karin Nordänger 《Educational studies》2007,33(1):15-27

This paper presents the argument that education and the teaching profession have been saturated by a new form of risk consciousness and risk consideration. The aim is to shed light on this issue and present a number of empirical examples and questions of interest in educational research. Furthermore, the paper presents some of the central theories regarding risk and an attempt is made to relate these theories to an epistemological framework. The article also emphasizes the problems and issues that arise from the way teachers think, experience and manage risk in their daily work, and examines how this affects their didactic intentions and, in the long run, also the pupils’ learning potential. It is the intention of the authors, in the scientific as well as in the professional discussion, to reintroduce the positive connections between teaching and risk zones, as well as between professional development and risk taking.  相似文献   

Relationship Reciprocation Modulates Resource Allocation in Adolescent Social Networks: Developmental Effects          下载免费PDF全文

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13–17; Study 2: N = 81, ages 13–16) investigated age group differences in the impact of relationship reciprocation within school‐based social networks on an experimental measure of cooperation behavior. Results suggest development between mid‐ and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social‐cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood.  相似文献

Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows

Known as the ‘third polar region’, the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there. Previous studies of birds, animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence. The adaptive processes during the initial phase of highland adaptation remain poorly understood. We studied a human commensal, the Eurasian Tree Sparrow, which has followed human agriculture to the Qinghai-Tibet Plateau. Despite strong phenotypic differentiation at multiple levels, in particular in muscle-related phenotypes, highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years. In a one-month acclimation experiment investigating phenotypic plasticity, we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes. Through population genetic analyses, we identified a signature of polygenic adaptation, whereby shifts in allele frequencies are spread across multiple loci, many of which are associated with muscle-related processes. Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution, shedding light on early stages of adaptive evolution to a novel environment.  相似文献   

Innovation in Education ‐‐ the Case for the Interactive Videodisc in Schools     

Peter Olaf Looms 《Educational Media International》2013,50(4):175-182

Abstract

This article explores the case of the videodisc in the context of the progress of technological innovation in the field of education. It looks at what the medium has to offer and the ways in which it is currently being used, before going on to consider the factors that may impede its acceptance and what can be done towards ensuring its implementation.  相似文献   

Social network analysis of international student mobility: uncovering the rise of regional hubs   总被引：1，自引：0，他引：1  

Yasar Kondakci  Svenja Bedenlier  Olaf Zawacki-Richter 《Higher Education》2018,75(3):517-535

Research on the patterns of international student mobility and the dynamics shaping these patterns has been dominated by studies reflecting a Western orientation, discourse, and understanding. Considering political, economic, cultural, historical, and ecological factors, this study argues that international student mobility is not only an issue of the economically developed, politically stable, and academically advanced Western world but also one that involves countries with different economic, political, and academic characteristics. Taking into account various theoretical orientations, this study argues that political, economic, cultural, and historical factors have led to the emergence of non-traditional destinations for international students; these countries are labeled as emergent regional hubs. In order to empirically test this, a social network analysis was conducted on a worldwide dataset representing 229 countries. The findings evidenced the strong position of traditional destinations for international students. However, the results also suggest the rise of several regional hubs, which are undergoing internationalization processes in different forms and with different rationales. The mobility patterns in emerging regional hubs deviate from those in traditional destinations, which fundamentally change the nature of internationalization in this context.  相似文献   

Academics’ Strategies and Obstacles in Achieving Collaboration between Universities and SMEs     

Karlsson  Jan  Booth  Shirley  Odenrick  Per 《Tertiary Education and Management》2007,13(3):187-201

There is an ongoing debate both in the United States and Europe about the need to develop a broader view of scholarship and the different activities connected with it, including ‘service to the community’. This empirical study reveals that researchers who are engaged in collaboration with small and medium enterprises (SMEs) encounter many hindrances within the academic structure and obstacles due cultural differences that needs to be overcome. But it is also evident that they are creative and learn different strategies in accomplishing their goals and they also bring back useful experiences and knowledge from their cooperation into their research and teaching within the academic organization. We suggest that attention should be paid to the broader and more elaborate view of collaborative knowledge production that we present in the article if university structures are to provide better support for their academic staff to interact profitably with the community, and thereby create a ‘win-win situation’ for everyone involved.

Digitalisation in higher education: mapping institutional approaches for teaching and learning     

Cathrine Edelhard Tømte  Trine Fossland  Per Olaf Aamodt  Lise Degn 《Quality in Higher Education》2019,25(1):98-114

This paper explores the digitalisation of teaching and learning understood as external processes, influenced by government and international trends and as internal processes within the institutions, in Denmark and Norway. These are countries with similarities regarding digitalisation and educational systems. In the internal processes, there was some use of digital technology in teaching and learning when initiated from administration including IT-staff, in collaboration with academic leaders. There was little or only limited reported use of technology for teaching and learning, when the processes were initiated by administration together with enthusiasts among faculty staff, who did not have leadership roles or influence on change. There was more reported use of technology in teaching and learning in Denmark than Norway. The paper discusses possible explanations for these findings and thus illuminates how processes of digitalisation are influenced by broader governance arrangements, institutional maturity and academic and administration staffs.  相似文献   

The effect of financial education on pupils’ financial knowledge and skills: Evidence from a Solomon four-group design

Abstract

The present study used a Solomon four-group quasi-experimental design to examine the short-term effect of a large-scale national financial education program on children’s knowledge and skills in responsible spending and performing transactions effectively. Our study included a representative sample of Dutch pupils in the fifth grade of primary school (N?=?2,650). Controlling for different children-specific characteristics, results showed that the program increased pupils’ knowledge and skills scores in performing transactions effectively, but not in responsible spending. The insights gained from the present study show how financial education programs that enable children to immediately apply what they learn in practice can improve children’s knowledge and skills regarding certain financial competencies.  相似文献
