Purpose: To describe the results of showing farmer learning videos through different types of volunteers.

Design/Methodology/Approach: Semi-structured interviews with volunteers from different occupational groups in Bangladesh, and a phone survey with 227 respondents.

Findings: Each occupational group acted differently. Shop keepers, tillage service providers, agricultural input and machine dealers reached fairly small audiences. Tea stall owners had large, male audiences. Non-governmental organisations and community-based organisations, reached more women. The cable TV (dish-line) operators showed the videos on local TV, but some were reluctant to do so again. The Union Information Service Centres showed the videos and reached women viewers. Half of the official government extension agents surveyed also showed the videos publically.

Practical Implication: This video featured maize, wheat and rice seeding machinery. Because the machinery is complex and requires hands-on training, this first video aimed to expose tillage and sowing service providers and farmers to the machinery, without trying to teach them how to use it. But some farmers were so interested that they watched the video many times to learn more about the equipment. Before farmers and service providers decide to buy machinery for direct seeding, they still want to see and learn from demonstration plantings, to examine first-hand how the crop behaves when planted with the new equipment.

Originality/Value: Video can be an effective way of sharing high-quality information with a large audience, if properly distributed.  相似文献

Current approaches to oral assessment of English in English secondary schools tend to concentrate more on ‘confidence’ and ‘participation’ than on the quality of children's thinking. This undermines the rich possibilities in classroom talk for cognitive development. Behavioural assessment approaches deny the essentially cognitive character of spoken English. This paper compares two brief representative extracts from a larger data‐set of students engaged in small group debate on the subject of abortion. One group of students are hindered in their discussion by an inability to conceptualize abstractly. It is suggested that a formative assessment approach based on a model of cognitive progression such as Vygotsky's could enable all students to develop as speakers by encouraging their teachers to focus more explicitly on the development of the quality of thinking. A sociocognitive framework for conceptual progression could guide teachers in their interpretation of peer debate in order to develop the quality of students' understanding and argument. Building on the work of Newman, Griffin and Cole, and Torrance and Pryor, further research should be conducted into the ways in which formative teacher–student and student–student assessment dialogue might enhance students' ability to think through talk.  相似文献

Community integration has increasingly become the focus of research and practice in the field of intellectual disability. Recent research has demonstrated that community integration needs to be more than simply living within a community, people need to use the community and feel like they belong. This study pioneers the use of a sense of community measure to better understand the degree to which feelings of belonging are associated with quality of life. One hundred and thirty two students from both urban and rural schools participated in this study. Half of them had an intellectual disability and the remainder were matched peers without a disability. Life satisfaction scores for adolescents with an intellectual disability were found to correlate significantly with reported levels of activity, friends and support in the neighbourhood. People with an intellectual disability reported lower usage of some community facilities and significantly lower social belonging and empowerment than their matched nondisabled peers. The groups did not differ significantly on the sense of community measure and the above patterns were true for both urban centres and rural towns.  相似文献

The number of university–industry R&D partnerships (UIPs) has increased significantly over the past decade, in most OECD countries and in Australia, yet the study of risk in such commercially focused collaborative ventures is still a developing area. This review paper seeks to contribute to debate on this increasingly important phenomenon by addressing three key areas of risks for universities in entering such collaborations. The commercialization of research findings presents particular risks to universities, most notably the possibility of financial loss, which has a greater impact than for companies in cross‐sector collaborations. Another major type of risk faced by universities is relational risk, and this can significantly alter the trust dynamics that underpin research and innovation. There are also institutional risks to universities and their research staff engaged in commercializable R&D and, ultimately, to their reputation as a neutral source of expertise. It is argued there is a need for universities in Australia to develop comprehensive policies to manage the risks of commercialization and R&D collaboration with industry partners.  相似文献

It is shown that cartesian product and pointwise-sum with a fixed compact set preserve various approximation-theoretic properties. Results for pointwise-sum are proved for F-spaces and so hold for any normed linear space, while the other results hold in general metric spaces. Applications are given to approximation of Lp-functions on the d-dimensional cube, 1?p<∞, by linear combinations of half-space characteristic functions; i.e., by Heaviside perceptron networks.  相似文献

Two property regimes for software development may be distinguished. Within corporations, on the one hand, a Private Regime obtains which excludes all outsiders from access to a firm's software assets. It is shown how the protective instruments of secrecy and both copyright and patent have been strengthened considerably during the last two decades. On the other, a Public Regime among hackers may be distinguished, initiated by individuals, organizations or firms, in which source code is freely exchanged. It is argued that copyright is put to novel use here: claiming their rights, authors write ‘open source licenses’ that allow public usage of the code, while at the same time regulating the inclusion of users. A ‘regulated commons’ is created. The analysis focuses successively on the most important open source licenses to emerge, the problem of possible incompatibility between them (especially as far as the dominant General Public License is concerned), and the fragmentation into several user communities that may result.  相似文献

Student-mothers who study vocationally related higher education programmes are a relatively under-researched group. Specifically, there is a paucity of research into the emotions that these learners experience. This article discusses a qualitative investigation that examined the emotional narratives that a group of vocational student-mothers offered. They were studying for a foundation degree for teaching assistants at a university in the North of England. The student-mothers were largely found to have experienced positive emotions. However, familial and workplace guilt had also been encountered. These emotions emanated from notions about how family and workplace time should be used. Student-mothers managed this cognitive dissonance by stressing the reciprocal relationships that existed between their studies, family lives and school work. However, for many of these learners familial and workplace guilt was a strong and continuing emotion.  相似文献

The National Committee on Science Education Standards and Assessment (1994 draft) viewed several science processes as important to an understanding of science as inquiry: formulating usable questions, planning experiments, conducting systematic observations, interpreting and analyzing data, drawing conclusions, communicating, and coordinating and implementing a full investigation. This study is one of three undertaken to develop research rubrics for a performance assessment of science processes and to evaluate seventh-grade science students' ability to perform them. Specifically, this article focuses on the processes of recording data, analyzing data, drawing conclusions, and providing evidence. A total of 364 students field tested the Alternative Assessment of Science Process Skills. Their responses were used to develop a research rubric, and then this rubric was used to determine response patterns that could inform both instruction and assessment of science process skills. Only 61% of students performed the activity and recorded data successfully. Sixty-nine percent of students did not attend to the hypothesis in drawing their conclusions. Eighty-one percent did not provide specific evidence for their conclusions. These results were discussed in light of relevant theories and models as well as their implications for instruction and assessment. © 1996 John Wiley & Sons, Inc.  相似文献

Financial and cultural aspects of corporate giving by UK and non-UK companies in response to the December 2004 South Asia Tsunami disaster are explored in this article. Literatures on corporate giving rationales, concepts of disaster and donor activity in disasters provide an underpinning. The article seeks to make connections between this high profile if short-lived business giving and the funding of the arts that is sought from business; and to draw tentative lessons for arts funding when seeking business support. The giving accounts in the wake of the Tsunami from a non-probability sample1 1. A probability sample is one in which each person (or company in this case) in the population has an equal chance (probability) of being selected. In a non-probability sample some people (in this case, companies) have a greater chance than others of being selected. For this study the availability of public information on the companies was the deciding factor on being selected. View all notes of 56 UK companies and 16 non-UK companies were examined. Reported online to the UK charity Business in the Community, these accounts were accessed in February 2005 and scrutinized thematically. Concurrently, company financial profiles to accompany giving figures were constructed. Although linkages between donation levels and financial performance were lacking, emerging themes included the role of employees, influencing company giving and creating a climate of expectation of firms' contributions. These developments may have important implications for business funding for the arts, where leading philanthropists are prominent as individuals in the giving landscapes; but employees' collective involvement is not marked. Alternatively, cultivation of employees as would-be donors, indirectly via their firms, may be a more secure, if lower level route to funding for some arts organizations than dependence on high profile business leaders. The article considers alternative scenarios for company giving in disaster contexts, including as a sustained and lasting giving theme or as company support as a ‘one-off’ event, rock-star style. The likely development of employee power as a key element in company giving is explored; and its wider meanings for funding in arts settings, (where the giver as rock star heroine/hero is also prominent) are considered.  相似文献
