Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts.  相似文献

This article outlines an interval estimation procedure that can be used in a 3-level setting to evaluate the proportion of outcome variance attributable to the second level of clustering. The method is useful for examining the necessity of including a possibly omitted intermediate level of nesting in analyses of data from a multilevel study, and represents an informative addendum to current statistical tests of second-level variance. The approach is developed within the framework of latent variable modeling and can be used as an aid in the process of choosing between 2-level and 3-level models in a hierarchical design. The discussed procedure is illustrated with an empirical example.  相似文献

The purpose of this study was to investigate the extent to which Lebanese Baccalaureate II students' (Freshmen in american colleges) perceptions of their academic abilities match their actual achievements in both school and government examinations. A population sample of 2999 students were selected from a representative school sample (n = 122) throughout Lebanon. Students' demographic data, occupational choices and perceptions of their achievement were collected by a three-part questionnaire. Their cumulative grade averages in school and in government examinations were standardized and used to assess their career maturity. Findings indicated that most students wanted to become engineers or physicians while their actual achievement scores in school was average and in the government examination below average. Most correlational values between perceptions and actual achievement scores were either negative or insignificant. Students were found to make immature career decisions mainly because of the lack of any formal guidance programs in schools.  相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

On‐going attempts by governments to implement measures intended to eliminate environmental degradation in the nearshore waters of the Great Lakes have revealed a critical need for integrative understanding that transcends disciplinary and professional specialisms. Academics from universities in the United States and Canada began, ten years ago, to meet with government officials and with people from nongovernmental organizations to find solutions to the problems in question. Groups of academics followed up these meetings with policy oriented studies using systems and transdisciplinary perspectives. Results have been readily disseminated into a wider constituency of interests because of the participation of nonacademics in the guiding of the studies. Similar collaborative approaches have been used to design role playing exercises for students in environmental studies courses at universities, using various Great Lakes situations as examples. An action learning/research mode lies at the core of environmental education at university level which also has considerable potential for addressing other global issues at universities.  相似文献
