西部与中东部地区的经济差距,使西部地区基础教育的素质教育的推进倍感艰难。但经济的落后和不发达,不能成为素质教育的阻碍。以四川宜宾为例,只要我们正确认识素质构成和素质教育的内涵,充分发掘本土的经济、历史、自然和人文景观资源,是完全可以实施素质教育,推进素质教育的进程的。  相似文献

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

Abstract

While existing research has shown the importance of the three interrelated domains of the wider policy, the school and home/community environments in the development of quality education for learners, this literature does not fully capture the experiences of the refugee population. In this article we focus on a group of Syrian refugees who came as part of the first large cohort that was welcomed in the UK in December 2015. We adapt Tikly’s quality education frameworks and develop a model that highlights not only the importance of the three intersecting environments, but also the specific inputs/processes that are critical to achieving quality education for refugees. In so doing, we stress the critical role of English as a tool for refugee children’s inclusion and integration in schools. Consequently, the contribution of the paper is an understanding of the inputs/processes that are key to the development of quality education for migrant/refugee children.  相似文献

Selecting the correct method for routine analysis by ‘method evaluation’ is an important component of quality assurance. It is a step-wise procedure that evaluates various analytical parameters like accuracy, precision etc of the given method. Finally reference intervals are established for selected population. We evaluated an enzymatic method for serum creatinine. The results show that it is an acceptable method based on the above mentioned criteria.  相似文献

In this paper we propose and test an evolutionary model of stylistic innovation, that is the change in the aesthetic and symbolic elements of products and services. Style is an increasingly relevant phenomenon in many industries and our goal is to develop a model of how styles get introduced and adopted. We build on existent literature on technological change to frame the dynamics of how style changes across time. In the model we propose, companies face periods of ferment with relevant stylistic variations and periods of convergence on a single trend—that is the stylistic convergent design versus the technologic dominant design. We identify the drivers of convergence in stylistic innovation. We test the model with a longitudinal empirical study (1984-2002) in the fine fashion industry, explaining the main differences between a stylistic and a technological evolutionary model.  相似文献
