Best-bet channels for integrated soil fertility management communication and dissemination along the agricultural product value-chain: a comparison of northern Ghana and western Kenya     

Ivan Solomon Adolwa  Andreas Buerkert 《The Journal of Agricultural Education and Extension》2018,24(5):435-456

Purpose: The aim of this paper is to comparatively assess the most suitable channels for dissemination of agricultural innovations along the entire information value chain.

Design/Methodology/Approach: We calculated information scores to measure channel preference from a randomly selected sample of farmers: 285 in Tamale, Ghana and 300 in Kakamega, Kenya. Using t-tests we compared the information score differences of different channels between farmers who adopted Integrated Soil Fertility Management and those who did not.

Findings: The highest information scores were observed for radio along the entire value chain for both locations. However, farmers in Tamale prefered interpersonal channels for processing information. Radio and farmer field days had the highest rankings for production information at both locations. Radio, workshops and interpersonal channels (traders and neighbours/friends/relatives) were best-bet channels for marketing and procesing information.

Practical implication: Extension agents should place more emphasis on channels such as radio, farmer field days, and workshops as they may offer more efficient delivery of information packages at all levels, whilst recognizing the central role of interpersonal channels.

Theoretical implication: The nexus between the uses and gratification, adoption, diffusion of innovations theories and the collaborative communication theory on one hand, and the agricultural product value chain framework on the other, is highlighted. Farmers’ preference for information channels is not predicated on the stage of the value chain.

Originality/Value: In the current context of weak agricultural knowledge and innovation systems in African agriculture, agricultural producers are poorly informed about the current innovations. This study furnishes empirical evidence on the best-bet information channels to be used by extension workers and change agents to disseminate and communicate system innovations.  相似文献   

Young children's recognition of the intentionality of teaching     

Ziv M  Solomon A  Frye D 《Child development》2008,79(5):1237-1256

Two studies examined the role of intention in preschoolers' understanding of teaching. Three- to 5-year-olds judged stories in which there was an intention to teach or not (teaching vs. imitation) for 4 different learning outcomes (successful, partial, failed, and unknown). They also judged 2 stories with embedded instructional intent (e.g., guided discovery learning) and several standard theory of mind tasks. There was an age-related change in the understanding of teaching. Five-year-olds distinguished teaching from imitation and recognized guided discovery learning. Understanding of imitation and false belief was related. The findings indicate that theory of mind is relevant to other means of knowledge acquisition besides perceptual access and that understanding intention could help young children to recognize instruction and identify its different forms.  相似文献

Finding a voice? Narrating the female self in mathematics     

Yvette Solomon 《Educational Studies in Mathematics》2012,80(1-2):171-183

If mathematics is a male domain, where does this leave women who do mathematics? In a world where there is little or no discursive space in which to be female, women who enter in must do identity work in order to achieve what is often an uneasy presence. This paper builds on recent research which suggests that some undergraduate women are however finding new spaces for belonging in the world of mathematics through critical reflection and collective challenge to dominant discourses. Focussing on an analysis of two women’s narratives of their success in mathematics, it explores their multi-voiced accounts of self through the lens of Bakhtin’s dialogism. It discusses the scope of reflexivity in creating new identity spaces in refigured worlds.  相似文献   

Appraisal and Distancing Responses to Hurtful Messages II: A Diary Study of Dating Partners and Friends

This study examined the interaction between perceived cancer risk and self-efficacy related to cancer screening on cancer-related information seeking and scanning behaviors (SSB) among the general population. Individuals completed a cross-sectional survey, were classified into 1 of 4 clusters based on their relative risk and self-efficacy belief scores (i.e., high relative risk and high self-efficacy, high relative risk and low self-efficacy, low relative risk and high self-efficacy, and low relative risk and low self-efficacy), and asked about their information SSB related to the colonoscopy, prostate-specific antigen test, or mammogram. A national probability sample of 2,489 adults aged 40 to 70 took part in this study. Individuals who perceived themselves to be at high relative risk for cancer and had high self-efficacy beliefs in performing cancer-screening behaviors generally reported the highest amounts of SSB for cancer-screening information, compared to the others.  相似文献   

Talking up learning at work: Cautionary tales in co‐opting everyday learning     

David Boud  Donna Rooney  Nicky Solomon 《International Journal of Lifelong Education》2013,32(3):323-334

Learning in workplaces is always mediated through talk. It is tempting for management to seek to utilise everyday talk as part of learning and therefore enhance productivity. This paper examines the responses of workers to interventions that aim to formalise informal conversations at work as part of an explicit workplace learning strategy. It draws on interviews with managers and workers in a public sector organisation to examine their experience of these practices. The paper raises questions about whether interventions in the name of fostering informal learning may well be hindering what they seek to promote.  相似文献

The effect of an historical perspective on prospective teachers’ beliefs in learning mathematics     

Hailu Nigus Weldeana  Solomon Tewolde Abraham 《Journal of Mathematics Teacher Education》2014,17(4):303-330

Many learners hold traditional beliefs about mathematics that can hamper their learning in the discipline. To address this issue, a “history-based” intervention program entailing problem-solving and writing activities that instigate cognitive conflict was implemented. Data sources were pretest and posttest scores of a 12-theme questionnaire designed for this study called “Prospective teachers’ beliefs questionnaire about mathematics learning” and written reflections of prospective teachers. The survey of the prospective teachers beliefs related to the nature of mathematics and the way it is learned, taught, and practiced showed a great majority of them failed to hold progressive beliefs. Fortunately, the intervention program has helped the prospective teachers revise and correct their beliefs, thoughts, and understandings. Study of the prospective teachers’ written reflections and observations of their oral presentations during whole-class discussions strengthen the results of the quantitative study.  相似文献
