This paper presents the experiences and interpretations of children, parents, teachers and support persons concerning the implementation of supports in regular school environments in Flanders, Belgium. The data were gathered through observations, interviews and focus group meetings. Those multiple perspectives provide insights into the complexity of implementing supports in a regular education context. The conclusions offer some possibilities for debate and alternative ways of thinking about supports that facilitate inclusive school communities by tapping into resources such as the children, the environment, creativity and courage to leave the beaten path.  相似文献

This paper examines whether the closure of poor performing primary schools improved students' educational attainment. It is believed that school closure affects children's educational outcomes positively because children switch to better primary schools. At the same time, school closure creates a social disturbance such that educational outcomes may be affected negatively. There is no previous literature on the effect of this type of school closure on student performance. The empirical results indicate that student test scores are not affected by the school closure. Children are, however, tracked into higher secondary education levels after the school closure if they received more education years at the new primary school. This effect fades out and eventually becomes negative for children who received more than one education year at the new primary school. The results further suggest that there are no detrimental effects of a school closure in terms of educational performance.  相似文献

Abstract

The objective of this paper is to describe and analyse the role that study groups might play in improving the entrepreneurial competencies of farmers. The most important competencies are described. Emphasis is placed on group learning processes and participatory approaches. Theories of adult learning and extension paradigms in relation to our experiences in the ‘Innovative Entrepreneurship’ study are addressed. We conclude that in our research, participatory approaches and using study groups are an aid to gaining explicit and implicit knowledge. Consequently, they are effective methods for training entrepreneurial competencies and creating an environment in which participants are able to learn effectively.  相似文献

Abstract

This study investigated the extent to which the learning styles of Chinese students differ from those of Dutch students. The study was conducted within the context of Englishlanguage Bachelor of Science programmes thatWageningen University offers together with China Agricultural University to Dutch and Chinese students. Sixteen Dutch students and 25 Chinese students completed the Inventory of Learning Styles. The Chinese students have several of the characteristics that reflect a reproduction-directed and an undirected learning style, while the Dutch students as a group do not demonstrate any one particular learning style. It would be useful and desirable to show the Chinese students, by means of specific instructions and exercises, how to use strategies directed towards deep processing and how to regulate their own learning processes more in the direction of deep processing.  相似文献

Abstract

Purpose: This article explores the views of Smallholder Marketing Cooperatives’ (SMCs) leaders and staff, to gain insight about the particular roles SMCs play in facilitating smallholders’ market access.

Design/methodology/approach: The authors conceptualized and executed two international workshops in which participants from 42 SMCs from 24 countries deliberated their lessons learned from real-life experiences.

Findings: Participants defined three core issues to be tackled by SMCs to play their role related to facilitating their members’ market access: good FO governance and management; access to capital and networking. They highlighted that smallholders’ market access improves not only as a result of SMCs networking and negotiation with key actors in the public and private sectors, but also due to improved interrelationships among SMCs and other types of Farmers’ Organizations (FOs). Peer-to-peer relationships with other SMCs are critical for mutual learning, collaboration and collective action.

Practical implications: Peer-to-peer relationships among SMCs are crucial for them to overcome the internal and external social dilemmas SMCs are bound to face while improving smallholders’ market access. This goes beyond the three kinds of relationships that scholars have pointed out thus far needed for effective FO development (relationships with members; the public sector and civil society; and with market players). This can be promoted and supported by development programmes.

Originality/value: Most SMC studies concentrate primarily on their efficiency in production and marketing activities. This research proposes looking beyond this perspective, using a qualitative approach to explore the real-life experiences and views of actors involved.  相似文献

Abstract

Based on a conceptual framework, that describes the relationship between the effectiveness of up-scaling participation and implementing decentralisation, the objective of this paper is to analyse the effectiveness of decentralisation measures in the Agricultural Technology System (ATS) of Vietnam. It discusses whether the decentralisation efforts so far have enabled the rural population to express their options and take joint decisions in the sense of participation. The paper uses primary and secondary data, collected between November 2000 and June 2001. The paper first discusses the theoretical literature on up-scaling participation and decentralisation. Emphasis is given to highlight the links between the concepts of good governance in decentralisation and its effects on people's participation in the decision making process. Thereafter, the Vietnamese decentralisation measures are reviewed and it is assessed to which extent the agricultural sector and its relevant state agencies have benefited from these efforts. The experiences from the decentralisation activities is summarised. Whether decentralisation opened space for the rural people to express their opinions and to ensure that their preferences are incorporated in the ATS is specially considered. The paper closes with recommendations.  相似文献

Abstract

Will African farmers watch and learn from videos featuring farmers in Bangladesh? Learning videos on rice seed management were made with rural women in Bangladesh. By using a new approach, called zooming-in, zooming-out, the videos were of regional relevance and locally appropriate. When the Africa Rice Center (AfricaRice) introduced them to Africa in 2005, many scientists and civil servants thought that the videos would be culturally inappropriate and hence irrelevant to African smallholder farmers. However, African farmers who watched the videos did not experience cultural barriers. In fact, they enjoyed seeing another part of the world where farmers faced similar problems as theirs, and were able to solve these problems by themselves. To promote wider uptake of the videos a key challenge was to overcome the institutional barriers. Public sector agencies especially had to be convinced that African smallholders appreciated Asian videos. By watching the videos with farmers and listening to their feedback, the skeptical scientists and service providers changed their minds. By 2009, the Bangladeshi rice seed videos had been translated into 20 African languages and so became national products. Videos made according to the zooming-in zooming-out approach can bring farmer-to-farmer extension to a higher level of social aggregation.  相似文献

The present study addresses the impact of the curriculum on primary school children’s acquisition of clock-reading knowledge from analog and digital clocks. Focusing on Chinese and Flemish children’s clock-reading knowledge, the study is about whether the differences in sequencing of learning and instruction opportunities—as defined by the curriculum—result in differences in accuracy and development of clock-reading knowledge. By means of (1) an in-depth qualitative analysis of the Chinese and Flemish mathematics curriculum standards and textbooks and (2) a quantitative analysis of 11,743 students’ accuracy in reading the time, the current study mirrors the differential impact of alternative curriculum designs for primary education. The results of the analyses reveal that Chinese children acquire clock-reading knowledge—for analog and digital clocks—2 years earlier than their Flemish peers, due to a 2-year earlier exposure. Discussing these results, it is argued that the Flemish curriculum tends to underestimate what children are capable of and that clock-reading within the Flemish primary mathematics curriculum builds on dated assumptions and research results. Building on these outcomes, it is argued that curriculum development should be the result of collaborative inquiry involving policy makers, researchers, and teachers.  相似文献

In the field of educational effectiveness research, the influence of a class’ student body on students’ individual achievement scores has been a popular research interest for many years. Yet, few studies have focussed on the effects of class composition on students’ non-achievement outcomes, and up to now, hardly any attempts have been made to summarize the findings of previous studies on this topic by conducting a literature review. The current study tries to fill in this gap and focuses on the effects of class composition in secondary education in terms of ability and gender on students’ school well-being and academic self-concept. The results of this literature review indicate that ability grouping is beneficial for strong students’ school well-being, but rather detrimental for the school well-being of weak students. The reverse holds for students’ academic self-concept. Furthermore, our results show that single-sex classes are advantageous for girls’ school well-being and academic self-concept. As for boys, the results are inconclusive.  相似文献

This paper reviews the literature on the effects of feedback provided to teams in higher education or organizational settings. This review (59 empirical articles) showed that most of the feedback applications concerned “knowledge of results” (performance feedback). In contrast, there is a relatively small body of research using feedback conveying information regarding the way individuals or the team performed a task (process feedback). Moreover, no research compared the effectiveness of process versus performance feedback. Concerning feedback effectiveness, half of the studies implementing performance feedback research reported uniformly positive effects while the other half resulted in positive effects on some dependent variables and no effect on others. All the studies using solely process feedback showed mixed positive results: some dependent variables improved while some others did not change. None of the studies reported any negative effects. This review also highlighted 28 key factors supporting feedback interventions effectiveness.  相似文献
