Global Rivers Environmental Education Network (GREEN) is an international network that seeks to bring students, teachers, and communities in the world closer together through the bond of studying and improving our river systems. The network is an expanding global communication system that invites participants to analyze watershed usage, monitor the quality and quantity of river water, reflect on ways that land and water usage and cultural perceptions influence river systems, and present their findings and recommendations to appropriate governmental and nongovernmental organizations. The pedagogical model that GREEN has been working under is Action Research and Community Problem Solving (ARCPS). It is a process that enables students and teachers to participate more fully in the planning, implementation, and evaluation of educational activities aimed at resolving an issue that the learners have identified. Some of the cornerstones of the instructional approaches are watershed analysis, experiential learning, interdisciplinary orientation, integrated problem solving, action-taking, and the support of networks. GREEN encourages classrooms to consider a cross-cultural component to their watershed education program in an effort to further global citizenship by linking students, teachers, and community members from different regions of the world.  相似文献

This study aimed to determine how 33 urban 5th grade students' science conceptions changed during a place‐based inquiry unit on watersheds. Research on watershed and place‐based education was used as a framework to guide the teaching of the unit as well as the research study. A teacher‐researcher designed the curriculum, taught the unit and conducted the research using qualitative data sources such as concept maps, science notebooks and interviews. Most students came to understand that their watershed was part of an urban environment where water drains from the surrounding land into a body of water. Thus, they began to understand how urban land use affects water quality. This study provides evidence for the use of place‐based learning in developing students' knowledge of the National Science Education Standards (NRC, 1996) and watersheds. Implications of this study include the use of place‐based learning in urban settings and the experiences needed for students to conceptualize watersheds. © 2009 Wiley Periodicals, Inc.

Abstract

The Rouge Education Project (REP) is a school-based environmental education program that uses water monitoring, telecommunications, and student actions to improve water quality. The author carried out a program evaluation to better understand the challenges generated by such a program. She examined surveys, interviews, and focus groups to determine the level of participation, goals, objectives, value of support services, and changes in teaching and environmental awareness. The results indicated that the REP met its goals of increasing awareness and concern about the Rouge River and developing a supportive curriculum in science classrooms. This article illustrates the importance of inservice workshops and curriculum resources for successful program enactment.  相似文献

Abstract

We assess the long-term effectiveness of outreach and education efforts associated with a water quality improvement project in a watershed located in northern Utah, USA. Conducted 15 years after the original project began, our research examines the lasting impacts of different extension activities on landowners’ motivations to participate and their awareness and understanding of the water quality problem. Data were gathered by reviewing annual project reports, interviewing project staff about outreach and education efforts, and conducting in-depth, semi-structured interviews with a majority of the farmers and ranchers who participated in the project. The findings suggest that landowners were motivated to participate in the programme more by practical farm and household considerations and available cost-share opportunities than by particular environmental concerns. Previous relationships between farmers and government programme staff and one-on-one visits with landowners played an important role in their decisions to participate, while demonstration projects and peer-to-peer social diffusion processes played a much smaller role than expected. Although participants had a good grasp of the project goals, they did not have a strong sense of ownership of the water quality problem. These results suggest that education and outreach approaches centred only on the environmental dimensions of conservation projects may be insufficient to motivate changes in conservation behaviour. The results also suggest that conventional outreach strategies often did not have their presumed impact on landowners.  相似文献

Abstract

This paper reports on the social learning from a project aimed to increase the knowledge and capacity of a group of farmers in Tasmania, Australia, to reduce the impacts of intensive agriculture on soil health and waterways, and to optimise the efficient use of on-farm inputs. The plan-do-check-review cycle adopted in this project required the farmers to assess current management practices, identify where to make changes, implement changes and monitor for improvements. The success of the project was due to careful attention to social processes as well as technical input. The combination of group activities with individual mentoring and one-to-one advice was key to the success of this project in enabling farmers to undertake on-farm action.

There is value in social learning that included developing relationships, using one-to-one contact and group workshops together with expert input when working with farmers to tackle some difficult and complex interrelated natural resource management and production issues. Sufficient time must be allowed for the process of facilitating good practice in natural resource management, particularly when addressing systemic environmental impacts. Practical operational recommendations are presented on communication, feedback, focus of activities and meeting content, as these will be useful to other project officers and facilitators working with farmer groups.  相似文献

Abstract

The process of innovation-development to scaling is varied and complex. Various actors are involved in every stage of the process. In scaling the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)-led integrated watershed management projects in India and South Asia, three drivers were identified—islanding approach, multi-layered partnership, and innovative means of knowledge sharing. Through a consortium mode of partnership, ICRISAT established ‘islands’ or models for showcasing soil and water conservation interventions and integrated these with other concerns of the farming system (crops and livestock) and socio-economic dimension (capacity building). Activities on the islands were planned and implemented by the locals and replicated in satellite watersheds. Partnerships forged through the consortium approach provided a dearth of resources such as social capital. Projects built on trust and good relationships can be sustained even when direct financial support ceases. Innovative means of knowledge sharing like the Virtual Academy for the Semi-Arid Tropics (VASAT)—ICRISAT's innovation in capacity building and information management—provided the link between rural farm households and researchers. Credible intermediaries and markets were linked to farmers by information communication technology channels and markets through an interface of information and open/distance learning methods. VASAT's multi-dimensional strategy has been an important resource for a south–south partnership.  相似文献

Bringing Science to Life Through Community-Based Watershed Education   总被引:2,自引:1,他引:1  
Four elements of successful student-scientist partnerships (SSPs) have been identified through experience in a wide variety of educational settings. SSPs should: use an inquiry-based approach to education; be built around authentic, community-based investigations; let students be scientists; and allow scientists to be educators. Each element is discussed and illuminated with examples from case studies of watershed education programs that are based on an interdisciplinary, action-oriented watershed education model developed by the Global Rivers Environmental Education Network (GREEN).  相似文献

Abstract

This article examines the extent to which impacts of a conditional cash transfer (CCT) program on children's academic outcomes vary by key characteristics associated with families’ propensity to earn the rewards offered by the program. We utilize an experimental study of Opportunity NYC-Family Rewards, a comprehensive CCT program in New York City in which low-income families were offered rewards for outcomes in health, education, and work. Building from a technique in propensity score research but used here to assess subgroup impacts in experimental studies, we use multiple baseline characteristics to predict the amount of rewards earned as a means to identify theoretically important, multivariate-defined groups of children for whom program effects might be more concentrated. Fourth-grade children in families with higher likelihood to earn rewards experienced more positive impacts of the program on academic outcomes. By contrast, no program impacts were found among 7th- or 9th-graders whose families were most likely to earn rewards. Differences across age groups are discussed in terms of their different developmental periods and the differing way the children experienced the intervention.  相似文献

以延河流域为典型研究区,构建土地资源承载力评测模型,从定性与定量的角度对研究区的土地资源承载力进行动态测评与时空差异性分析。结果表明:在2000年到2010年间,各个区县土地资源承载力都呈现出两级分化的趋势,虽然两级分化的程度有所差异,但总的趋势是一致的,说明研究区整体土地资源承载力水平下降,需要借助于高效合理、科学的土地优化配置来提高土地资源承载力。对于整个研究区两极分化的情况,应当保证在土地资源承载力富余地区经济稳定发展的情况下,将富余地区的粮食外调给土地资源承载力超载的地区,实现整个区域的土地资源承载力平衡。  相似文献

Abstract

The need for education and understanding about the continuing soil erosion problem is acute. Most segments of the population have little knowledge of the critical impacts erosion can have on the environment. The use of the Soil Conservation Service model for erosion determination, the Universal Soil Loss Equation (USLE), is a good perceptual tool to show the impacts of human and natural action on the land. Micro-DYNAMO, a special-purpose computer simulation language, was programmed to simulate the USLE under several different environmental and farming practice scenarios. This type of simulation will never duplicate nature but will allow natural processes to be evaluated and this information to be used for rational decision making and understanding.  相似文献

Abstract

Networked learning aims to foster students’ knowledge construction processes as well as the quality of knowledge construction. In this respect, it is crucial to be able to analyse both aspects of networked learning. Based on theories on networked learning and the empirical work of relevant authors in this domain, two coding schemes are presented to analyse the nature of learning processes and the quality of knowledge construction in networked learning. The coding schemes were used to analyse the learning processes and learning results of students in an MSc course on land use planning at Wageningen University in which networked learning played an important role. The inter-rater reliability of both instruments appeared to be satisfactory. The relation between the two coding schemes is discussed and recommendations for future research and educational practice are formulated.  相似文献

Abstract

Knowledge and perceptions of Michigan residents about groundwater were assessed so that a comprehensive educational program could be developed and baseline information established to document the program's impact over time. Data were collected from 663 residents in urban, rural, and farm households. Results indicated that knowledge about groundwater was moderate and that a statewide educational campaign on facts about groundwater was necessary. People perceived that land use practices affected groundwater quality at the national, state, and county levels but not at their household level. Significant differences were found among urban, rural, and farm residents and between farmers and nonfarmers in their perceptions of the effects of land use on groundwater quality.  相似文献

Abstract

Purpose: Why do farmers not take better care of their soils? This article aims to give insight into how farmers look at soil quality management.

Design/methodology/approach: It analyses diverse land management practices and visions on soils and soil quality of ten agroecological and 14 conventional smallholder farmers in Araponga, Minas Gerais, Brazil. As agroecological farming (that is, managing soils with minimum use of external inputs) requires more complex knowledge, it is assumed that agroecological farmers would be more knowledgeable on soils compared to conventional farmers. This case study tests the hypothesis that differences in land management practices between agroecological and conventional farmers can be explained by differences in their knowledge on soils.

Findings: The hypothesis turned out to be faulty: agroecological and conventional farmers do not differ in what they know about soils, but how they use their knowledge in their farming strategy. Both groups of farmers have different but rational farming strategies.

Practical implications: Designing policies and measures to make farming more environmentally friendly and more sustainable as two-way knowledge exchange between farmers and science (and not as one-way knowledge transfer from science to farmers), to benefit from vital and context-based farmers’ knowledge and to ensure successful implementation of more sustainable land management practices.

Originality/value: By analysing farmers’ visions on soil quality management and farming strategies, this study shows that farmers’ knowledge is valuable for farmers, for scientific knowledge on soil quality management and for policies which are to be effective and adapted to the local environment.  相似文献

BackgroundPeople who inject drugs (PWID) often contend with chronic pain as a result of illness and trauma, and such pain is known to have significant impacts on mental health, quality of life, and substance use behaviours. Although PWID are also known to have high rates of childhood trauma, little is known about how childhood emotional abuse may be associated with chronic pain in this population.ObjectiveWe undertook this study to explore emotional abuse and chronic pain among PWID.Participants and settingThis study comprised a total of 1459 participants in Vancouver, Canada between June 2014 and November 2016.MethodsWe employed multivariable generalized estimating equations with data derived from two prospective cohort studies of community-recruited PWID to examine the relationship between childhood emotional abuse and chronic pain in the past six months.ResultsAmong eligible participants, 591 (40.5%) reported childhood emotional abuse, and 760 (52.1%) reported chronic pain in the previous six months. In a multivariable analysis, experiencing childhood emotional abuse remained independently associated with chronic pain (adjusted odds ratio: 1.25; 95% confidence interval: 1.01–1.53) after adjustment for a range of socio-demographic and drug use confounders.ConclusionsOur findings suggest that childhood emotional abuse may have lasting relationships with chronic pain among PWID, potentially through established physiological and psychological mechanisms. Current chronic pain treatment may benefit from the evaluation of life course vulnerabilities that may be amenable to earlier interventions. Further, increased availability of effective trauma-informed chronic pain treatment is needed among this vulnerable population.  相似文献

BackgroundDespite strong associations between adverse childhood experiences (ACEs) and poor health, few studies have examined the cumulative impact of ACEs on causes of childhood mortality.MethodsThis study explored if data routinely collected by child death overview panels (CDOPs) could be used to measure ACE exposure and examined associations between ACEs and child death categories. Data covering four years (2012–2016) of cases from a CDOP in North West England were examined.ResultsOf 489 cases, 20% were identified as having ≥4 ACEs. Deaths of children with ≥4 ACEs were 22.26 (5.72–86.59) times more likely (than those with 0 ACEs) to be classified as ‘avoidable and non-natural’ causes (e.g., injury, abuse, suicide; compared with ‘genetic and medical conditions’). Such children were also 3.44 (1.75–6.73) times more likely to have their deaths classified as ‘chronic and acute conditions’.ConclusionsThis study evidences that a history of ACEs can be compiled from CDOP records. Measurements of ACE prevalence in retrospective studies will miss individuals who died in childhood and may underestimate the impacts of ACEs on lifetime health. Strong associations between ACEs and deaths from ‘chronic and acute conditions’ suggest that ACEs may be important factors in child deaths in addition to those classified as ‘avoidable and non-natural’. Results add to an already compelling case for ACE prevention in the general population and families affected by child health problems. Broader use of routinely collected child death records could play an important role in improving multi-agency awareness of ACEs and their negative health and mortality risks as well in the development of ACE informed responses.  相似文献
