A course for upper division undergraduate students was developed in response to a request for a cross-disciplinary course in environmental sustainability with an emphasis on an international issue. The topic selected for the course focused on the energy needs for Chile and a proposal for five hydropower projects on the Baker and Pascua Rivers in the Patagonia area. Collaborations between the University of Michigan (USA) and the University of Concepción (Chile) to develop the course led to a plan to offer a parallel course at both universities, with the students of both courses participating in a site visit to Patagonia. The courses were structured to enhance learning through interdisciplinary team-based activities. The courses were taught in a seminar format, with invited lecturers to provide background information on technical, environmental, economic, social, and political issues surrounding hydropower development in general and the proposed projects in particular. The students combined this information with insights obtained during the site visit to prepare a variety of course products, notably an assessment of the concerns of the various affected stakeholder groups. Assessment of the course outcomes is discussed.  相似文献

One of the most important and yet difficult challenges that modern societies face is how to mobilize science and technology (S&T) to minimize the impact of human activities on the Earth’s life support systems. As the establishment of inter-disciplinary education programs is necessary to design a unified vision towards understanding the complexity of human nature, the Research Institute for Sustainability Science (RISS) launched a new program on sustainability science in April 2008. The program expects to address the issue of how to use knowledge more effectively to understand the dynamic interactions between nature and human society. This paper first offers an overview of international and Japanese initiatives on sustainability education in which we highlight the uniqueness of the attempt by the Integrated Research System for Sustainability Science (IR3S). The paper then introduces the RISS program for sustainability science, addressing the principles and curriculum design of the program. The paper discusses the main problems and constraints faced when developing the program, such as institutional barriers in building a curriculum and obtaining cooperation from faculty. To challenge these barriers and limitations, the RISS uses the program as a platform to disseminate the idea of sustainability science across the university. This attempt helps us to obtain the continuing cooperation necessary to improve and maintain the program.

An educational project on biological monitoring of air quality was launched in 2004 to involve about 650 young students (age 6 to 16) from 21 schools of nine municipalities in Tuscany (Central Italy) in active detection of the crucial pollutant ozone with indicator sensitive tobacco seedlings. Results implied the reading of 9,300 raw biological figures and were fortified by the data captured by six photometric analysers. Under the guidance of their teachers, the students had several opportunities to practice with many basic and applied study areas and were initiated into the scientific method in a simple and absorbing manner. Curiosity and involvement were widespread; a sort of emotional and responsible relationship was developed by several pupils. Though primarily an educational exercise, the survey introduced a research element and the regional picture of air pollution that emerged has increased our knowledge of the air quality situation in the area. Biological monitoring of air quality is a powerful tool to improve the awareness and involvement in key topics of environmental education. In addition, it represents a crucial element for improving the awareness of problems and implies the active participation of citizens in the assessment of several indicators of the state of the environment. Its potential as a robust implement in landscape and urban planning is noteworthy.  相似文献

This study examines and critiques “nature-deficit disorder” (NDD), Richard Louv's popular theory of how and why children are alienated from nature. Specifically, I explore NDD within the context of one forest conservation education program that aligns with and operationalizes Louv's message. Underlying Louv's and forest educators' discourses are culturally specific assumptions about human-nature relationships. Both evoke a fall-recovery narrative—that children are separated from nature and must return—and promote science and naming to reconnect. I argue that, in the absence of deeper cultural examination and alternative practices, NDD is a misdiagnosis—a problematic contemporary environmental discourse that can obscure and mistreat the problem. I call on adults to rethink human-nature disconnectedness by returning to the psyche, digging deeper to the problem's cultural roots, and using nontraditional communication practices such as emotional expression and non-naming.  相似文献

Children in refugee camps, and particularly those with disabilities, face unique challenges in accessing education and are at high risk of being marginalised. Best practices suggest that main-streaming is the optimal strategy for serving students with disabilities. This study examines the extent to which mainstreaming in a refugee camp helps to promote children's prosocial behaviours, taking into account their emotional and behavioural problems. In Kakuma Refugee Camp, Kenya, researchers collected data from the parents of children currently enrolled in special needs education centres (n=65) and from those formerly enrolled at these facilities who transitioned to mainstream classrooms (n=81). Children in mainstream schools functioned better in terms of prosocial behaviours, but this relationship disappeared when factoring in children's emotional and behavioural difficulties. In the context of a refugee camp, mainstreaming alone is not likely to help children's psychosocial and educational functioning, which requires dedicated supports, appropriate facilities and infrastructure, and a dual focus on disability-specific and disability-inclusive initiatives.  相似文献

Perceptions, knowledge and mitigation are factors that might play a role in preventing injury and loss of life during a major earthquake.2 Little is known about the relationships between different demographic and educational parameters and these factors. A national representative sample of 495 adults was investigated in order to determine the relationship between demographic and educational parameters in terms of the perceived threat, perceived coping, knowledge and mitigation of earthquakes in Israel. Compared to females, males perceived the threat of earthquakes to be lower (t=3.183, p=0.002), manifested higher levels of perceived coping (t=2.55, p=0.011), and had higher levels of earthquake related knowledge (t=2.047, p=0.041). We conclude that there are gender differences in perceptions and knowledge regarding earthquakes.  相似文献

The author uses two publications, Fighting Poverty in the US and Europe (Alesina and Glaeser) and Poetry magazine, to underscore the important role that educational institutions play in developing a person’s political philosophy and imagination. European nations, for instance, have better funded social welfare programs than the US because their system of public education incorporates more liberal or left-leaning teachings into their standard curricula. The author sees implications for a more intentional approach to education in the US for those who are interested in changing the food system. If American educational institutions viewed their role as producing food competent citizens, he argues, then we would be more successful in addressing obesity, promoting a more sustainable food system, and even reducing poverty. Food system activists, dieticians and nutritionists, parents, and elected officials should take a more aggressive position with educational institutions to develop programs, services, and curricula capable of achieving these ends.  相似文献
