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

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: = 42, ages 13–17; Study 2: = 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

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

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.

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

Background: Sustainable development, as an area of knowledge, appears in several different places in the curriculum and does not fit neatly within the scope of traditional subject areas. In many countries, including Sweden, it has long been upheld as an important tool for increasing understanding of, and dealing with, environmental problems. It is not clear, however, what role education can actually have in the making of a more sustainable future. Even though there are several potential ways for sustainable development to be involved in education, the concept raises many questions when transferred to the school context.

Purpose: This paper investigates how teachers deal with the difficulty of defining and approaching sustainable development as an area of knowledge in Swedish schools.

Sample: This article is based on semi-structured interviews with 40 teachers, 13 of whom were lower secondary school teachers (pupil age 12–15) and 27 were upper secondary school teachers (pupil age 15–18). The study involves teachers in all subjects where sustainable development is a goal in the syllabus. The study is also based on participant observation in one upper secondary class. A total of 17 different schools were involved, from a wide range of locations in Sweden.

Design and methods: The paper builds on qualitative data and the analysis of transcribed interviews and group interviews with teachers in Swedish lower and upper secondary schools. Group interviews, involving three or more people, were conducted on eight occasions. The pupils at an upper secondary school were also observed while they were working on a course called ‘policy and sustainable development’. Data were transcribed and analysed thematically.

Findings: The analysis suggests that, according to the teachers’ experiences, the demands of equivalence and measurability in school have increased and that this affects how sustainable development is approached in teaching and learning. Three main categories of knowledge were identified. The study also presents two representations that model how teachers may approach knowledge about sustainable development – metaphorically termed ‘the Accountant’ and ‘the Adventurer’ – and their different effects on knowledge.

Conclusions: There is a tendency for complex knowledge areas such as sustainable development, which do not fit seamlessly into traditional curriculum subjects, to become oversimplified when translated into teaching situations. According to the representations that we described metaphorically, the teacher, as an accountant, is characterised by ‘knowledge instrumentalism’, which means that teachers administer knowledge and the pupils consume it. In this transactional model, the accountant is also very dependent on external governance and control. Alternatively, the teacher, as an adventurer, is characterised by authority, knowledge and self-control. In this model, knowledge sometimes grows in an unpredictable way in the meeting between people who share common experiences. For adventurers, sustainable development is a matter of commitment and awareness, and it involves an explicit stance. The metaphors can be placed on a continuum which describes how teachers manage the demands of the school system in relation to the knowledge area of sustainable development.  相似文献

The purpose of this study is to investigate the ways in which Swedish seventh grade students (12 and 13 years old) handle chance encounters. Four groups of students working in pairs participated in the study. In the group discussions, which were tape-recorded and fully transcribed, the students were encouraged to explore strategies for winning a specifically designed dice game based on the sum of two dice. The dice game included four different set-ups of dice designed to bring to the fore different aspects of probability modelling and to offer the student the opportunity to encounter small differences in the mathematical structure of the sample space and of the probability distribution between the four different set-ups. The study describes strategies that the students use when confronted with these different set-ups, what their activities imply in terms of resources in handling random phenomena and what the dice game offers in terms of opportunities for learning probability. In order to explain such meaning-making processes the students’ activities are viewed from a perspective that takes into consideration how the students’ understanding varies with their interpretations of the situation they are confronted with, i.e., how they contextualize the different set-ups of the dice game. The results show how the students, during the course of the game, reorganize their interpretations of the mathematical content confronting them, and how a variation of guiding principles becomes the object of exploration. Approaches of extremes and a number model are described as a means for the students to identify and assign probabilities for the total of two dice.  相似文献
