Erik De Corte 《Learning Inquiry》2007,1(1):19-30
Starting from a brief analysis of adaptive competence in mathematics, this article describes a series of research-based characteristics
of the kind of learning processes that should be elicited in students to facilitate and support in them the progressive acquisition
of such competence. Four major characteristics are discussed in some detail: learning is constructive, self-regulated, situated
or contextual, and collaborative. A rather new approach to transfer of learning is then presented in which transfer is conceived
as the preparation for future learning. Throughout the article it is argued that, notwithstanding the progress made in research
on learning from instruction, numerous and complex issues and problems remain for continued inquiry. 相似文献

The aim of the present study was through semi-structured interviews to explore udeskole teacher’s perceptions of motivational factors and challenges while teaching regularly outside the classroom on a weekly basis during a year. Six females and two male udeskole teachers participated and answered an interview guide containing five themes about their motivations, student relations, teaching experiences, challenges and recognition. Udeskole was perceived to have substantial potentials to improve both academic learning and life skills and ‘the common third’, i.e. teacher–pupil relations, was mentioned as a value added to the indoor teaching. Health and safety issues were not perceived as barriers. 相似文献

Vacuum interrupter, high reliability component of distribution switches, circuit breakers and contactors 总被引:1,自引:0,他引:1

The use of vacuum interrupters(VIs)as the current interruption component for switches,circuit breakers,reclosers and contactors operating at distribution voltages has escalated since their introduction in the mid-1950’s.This electrical product has developed a dominating position for switching and protecting distribution circuits.VIs are even being introduced into switching products operating at transmission voltages.Among the reasons for the VI’s popularity are its compactness,its range of application,its low cost,its superb electrical and mechanical life and its ease of application.Its major advantage is its well-established reliability.In this paper we show how this reliability has been achieved by design,by mechanical life testing and by electrical performance testing.We introduce the“sealed for life”concept for the VI’s integrity.We discuss this in terms of what is meant by a practical leak rate for VIs with a life of over 30 years.We show that a simple high voltage withstand test is an easy and effective method for monitoring the long-term vacuum integrity.Finally we evaluate the need for routine inspection of this electrical product when it is used in adverse ambient environments. 相似文献

Age‐related differences in temporal discounting (TD) and risk taking, and their association, were examined in adolescents and young adults (n = 337) aged 12–27 years. Since monetary rewards are typically used in TD and risk‐taking tasks, the association between monetary reward valuation and age and decision making in these tasks was explored as well. TD declined linearly with age, with a particularly sharp decline from 15 to 16 years. In contrast, risk taking was not correlated with age and TD. Reward valuation was not associated with TD and risk taking, and age‐related differences in TD remained significant after controlling for reward valuation. Together, these findings suggest that risk taking and TD are two separate constructs with distinct age‐related differences in adolescence and young adulthood. 相似文献

This study examined workplace romantic relationship partners’ e‐mail practices and perceptions. Results suggest that the relationship may play an integral role in determining participants' uses and perceptions of e‐mail Workplace romantic couples used e‐mail as frequently as face‐to‐face communication to interact with romantic partners and rated it as both rich and important Participants used e‐mail for both work‐related and social tasks. In addition, participants used business e‐mail addresses for communicating with relational partners and perceived that few organizational policies existed regarding its use. Theoretically, these findings suggest the importance of studying the relationship as a factor that affects e‐mail practices and perceptions. Practically, results indicated that e‐mail may present an additional channel for enhancing communication and connectedness in workplace romantic relationships, and that organizations may need to reflect more carefully about policies concerning e‐mail use in the workplace. 相似文献

Suspense is a driving force behind media entertainment consumption. However, previous explorations of the role of suspense in the enjoyment of mediated sports have not fully relied upon the richness of research from other genres. The current study seeks to correct this oversight by using the lens of fictional drama to reconceptualize and reexamine suspense as a factor in the enjoyment of sports programming. A total of 161 participants viewed and rated 1 of 7 men's basketball games. The results suggest that a measure of the unfolding nature of suspense is a stronger predictor of mediated sports enjoyment than those used previously. 相似文献

In 1995 it became mandatory to establish individual educational plans (IEPs) for children with special educational needs in the Swedish compulsory school. On the basis of the pupils' needs, such a plan should contain information about the pupils' school situation and performance, the class, teaching etc. The aim of this article was to study how special educational needs are defined and described and what support measures the school is suggesting, using IEPs from a sample of Swedish compulsory schools. Our study is based on an analysis of IEPs for pupils with special educational needs in the nine‐year compulsory school in a municipality in northern Sweden. A strategic selection of three compulsory schools was made and we restricted the study to grades 3, 6 and 9. The method used to analyse the IEPs was content analysis. Using different theories within the field of special education and disability studies, we have tried to discern to what extent the problems described, and the proposed measures (intervention), are related to predetermined theoretical models of disability and special needs education. Our analysis indicates that difficulties are predominantly attributed to the pupils' shortcomings and individual characteristics, and the same holds for the recommended measures. Another interesting finding is that a number of the plans were established without involving the parents, and many of them did not even know that their child had an IEP. Finally, we discuss our findings in relation to different research traditions within the field of special education. 相似文献

Abstract:Ulvund, S. E. 1981. The Psychological Basis for the Identification of Physical Environmental Parameters in the Development of Early Cognitive Competence. Scandinavian Journal of Educational Research 25,125‐140. A theoretical analysis focussing on the identification of physical environmental parameters in the development of early cognitive competence is presented. Referring to cognitive competence as a collective term of cognitive behavior as considered by Piaget (1952) and Hunt (1965), a theoretical frame of reference based on Brunswik's (1955) unit and Wohlwill's (1973) conceptions of the environment as a source of stimulation versus the environment as a context for behavior, is discussed. It is further suggested that different variants of the optimal stimulation hypothesis, combined with a transactional model of development (Sameroff, 1975a), form a highly relevant psychological basis for the identification of physical environmental parameters. Some implications for coming research are suggested. 相似文献
