Purpose: This paper argues the rationale for a model of reflective practice in the formation of young agricultural advisors and to use this model to inform a wider discussion on the importance of the different levels of reflection in agricultural extension higher education.

Design/methodology/approach: The paper presents a model of four reflective practice modules conceived as successive building blocks in the professional development of a reflective agricultural advisor and examines the model through the lens of theory and the lens of experience of the first cohort of students to complete the programme.

Findings: Experiential learning with structured critical reflection is shown to support the integration of knowledge gained into new professional identities as agricultural advisors.

Practical Implications: Curricula for higher education in agricultural extension need to be revitalised and refreshed to address the mismatch between the emphasis on the social dimensions of extension in the literature and the general lack of attention to this in the education and formation of agricultural advisors.

Theoretical Implications: The paper presents a model of reflective practice that draws on experiences in other professions that could be applied to early career and continuing professional development for agricultural advisors.

Originality/Value: By presenting a model for reflective practice, the author intends to stimulate a wider discussion on the importance of the different levels of reflection in agricultural extension higher education.  相似文献

Purpose: The effectiveness of new extension approaches hinges on farmers’ willingness to adopt innovative ways to interact with extension. Therefore, this study explored farmers’ willingness to use mobile text messaging for two-way interactions with Ministry Extension officers.

Design/Methodology/Approach: Guided by the Unified Theory of Acceptance and Use of Technology (UTAUT), this study followed a correlational design and survey data were conveniently collected from 200 farmers of Trinidad.

Findings: Findings showed most farmers of the sample knew how to send and receive text messages, and many owned Internet-enabled smartphones. In addition, most farmers were willing to communicate with extension officers through text messages.

Practical Implications: Ministry Extension should revisit and revise their policies of communicating with farmers. Administrators should encourage extension officers to use SMS to respond to farmers’ requests and information needs.

Theoretical Implications: While the UTAUT provided an appropriate framework for understanding farmers’ use of text messaging, researchers should tailor the moderator variables to the country’s context.

Originality/Value: This study is the first to look at farmers’ willingness to use two-way information communication technologies in Trinidad. Results showed there is potential for Ministry Extension to use text messaging to communicate with farmers.  相似文献

Purpose: The limited uptake of improved agricultural practices in Africa raise questions on the functionality of current agricultural research systems. Our purpose is to explore the capacity for local innovation within the research systems of Ethiopia, Malawi and Mozambique.

Design/methodology/approach: Using Conservation Agriculture (CA) as a case study, we qualitatively explore with 26 locally based agricultural researchers the context of CA research and promotion, including their perceptions on persistent research gaps and issues in closing them.

Findings: Respondents identified that CA was not yet a finished product, with concerns regarding the benefit, feasibility and relevance of CA implementation. They asserted that while further adaptation was required, they were unable to do this due to institutional constraints within their research, extension and policy contexts.

Practical implications: We find that CA continues to be considered a donor-driven intervention in its current form and requires substantial further adaptation to local contexts before researchers will deem it ready for farmer uptake. The five research gaps identified by respondents highlight practical areas where further adaptations must occur.

Theoretical implications: Our findings suggest a lack of participatory research and extension most likely reflects limited financial, human and social capital to implement more participatory approaches. Without addressing these capacities, widespread adoption of complex farming systems change appears unlikely.

Originality/Value: Whilst many studies have identified a need for local innovation to enable CA utilisation, few have qualitatively explored directly with local researchers the capacity of such systems to do so. We address this gap in the literature.  相似文献

The case is stated for a scheme of professional training for adult educators, which should at once be

_____ comprehensive and unified;

_____ able to take into account the particular possibilities of individual adult educators; and

_____ easily adjustable to the particular needs within the community.

Such a scheme can only be realized through the application of a modular structure. A scheme like this is being developed at Gwent College of Higher Education for a professional training programme which will give a Certificate in Continuing Education, conferring full teacher status in adult and further education. This development is used to illustrate the points the author wants to make. The development of a programme on such a scheme raises considerable structural and methodological problems, which are discussed and compared with what is done elsewhere.  相似文献

Purpose: To investigate the need for sexuality education for individuals with adult onset physical disabilities as it relates to quality of life and to identify current trends in the provision of sexuality education by health care providers relating to quality of care.

Data Sources: Literature review from January 1986 to December 2016.

Study Selection: Studies were selected that outlined current trends in sexuality in health care, the impact of disability on sexuality, and sexuality education from the perspectives of both patients and health care providers.

Results: Searches in multiple databases yielded 41 articles that outlined the current state of sexuality education related to individuals with disabilities. The results demonstrate the importance of addressing sexuality after the onset of disability, and the inconsistencies that are present in health care practitioner education related to this topic.

Conclusion: Sexuality is an important aspect of the human experience and is greatly impacted by the onset of physical disability. Despite the acknowledgment of health care providers that sexuality should be addressed in clinical practice, there is a gap in knowledge and comfort stemming from a lack of formal education on this topic. In order to enhance the quality of services provided to individuals with physical disabilities, educational programs that focus on a multidisciplinary approach to sexuality education should be established.  相似文献

Background: As one part of scientific meta-knowledge, students’ meta-modelling knowledge should be promoted on different educational levels such as primary school, secondary school and university. This study focuses on the assessment of university students’ meta-modelling knowledge using a paper–pencil questionnaire.

Purpose: The general purpose of this study was to assess and to describe university students’ meta-modelling knowledge. More specifically, it was analysed to what extent the meta-modelling knowledge, as expressed in a questionnaire, depends on the scientific discipline to which university students relate their answer and the concrete model to which they refer while answering.

Sample: N = 184 students from one German university voluntarily participated in this study.

Design and methods: The questionnaire was developed based on a theoretical framework for model competence and includes constructed response items asking about the purpose of models, ways for testing models and reasons for changing models. Students written answers were first analysed qualitatively based on the theoretical framework to decide whether they expressed advanced understandings or not. Further analyses then were conducted quantitatively.

Results: Findings suggest that only few university students possess an advanced meta-modelling knowledge. However, significant more students who relate their answers to the STEM-disciplines expressed advanced understandings than those who referred to social sciences or linguistics/philology. Furthermore, university students who expressed an advanced meta-modelling knowledge referred to rather abstract kinds of models in order to explain their view.

Conclusions: The present study supports the assumption that meta-modelling knowledge may be situated and contextualised. Both the scientific discipline and the concrete model to which university students refer seem to be relevant item features influencing university students’ expressed meta-modelling knowledge. Implications for assessment and teaching are discussed in the article.  相似文献

Purpose: To identify and understand factors influencing farmers’ decisions to engage with extension activities. To understand farmer segments and how these factors vary in order to develop recommendations for future extension delivery.

Methodology: Qualitative data was obtained through semi-structured interviews with 30 Tasmanian dairy farmers. The Theory of Planned Behaviour (TPB) framework was used to identify and explore factors influencing farmer engagement intentions and behaviour.

Findings: There was a negative effect of social influence on experienced farmers’ intention to re-engage with extension, due to the belief extension activities were targeted to less experienced, younger farmers. Perceived control factors limiting engagement included lack of confidence about existing knowledge, resulting in farmers perceiving extension activities as confronting.

Practical implications: Key factors influencing intention to engage and continued engagement with extension were identified. These findings will inform future design and targeting of extension activities to improve initial and continued engagement. Subsequent recommendations are presented.

Theoretical implications: Previous TPB studies on adoption as an outcome of extension have typically focused on quantifying adoption predictions, rather than exploring how social factors interact and influence intentions and behaviours. This paper demonstrates how the TPB can be qualitatively applied to better understand farmer decision making, in this instance with respect to their initial and continued engagement with extension.

Originality/value: This paper demonstrates how the TPB can provide an evidence-based framework to qualitatively explore farmer intentions and behaviour. This approach has led to new insights into farmer decision making that will inform improvements in future extension development.  相似文献

Purpose: This study evaluates the impact of an outsourced extension service delivered by Lima Rural Development Foundation (Lima) in the Umzimkhulu district of South Africa. The evaluation is conducted at both the household and program levels.

Design/methodology/approach: Household impacts were estimated using two-stage regression with instrumental variables to account for selection bias. Gains in household income were extrapolated to estimate the net incremental benefit of the program and its financial return at district level. These analyses were underpinned by a rigorous sampling design.

Findings: The results show that the outsourced extension service made a significant and substantial contribution to household crop income and net income. In addition, clients perceived a range of socio-economic benefits such as better diets, improved product quality, and job creation. Analysis of the financial cost and benefit of the extension service at district level suggests an annual net incremental benefit of R5 million (US$0.4 million), and a 95% probability that returns to the service exceeded 20% in 2012/2013.

Practical implications: These results suggest that there is good reason for donors to continue funding effective extension services to small farmers in areas of high agricultural potential.

Theoretical implications: This is an empirical study. It uses well-established methods to measure the impact but introduces a local economy multiplier to capture some of the indirect effects of agricultural extension.

Originality/value: This research is valuable as very few studies worldwide have evaluated the impact of agricultural extension services at both the farm and program levels.  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

Purpose: This paper highlights important lessons for co-innovation drawn from three ex-post case study innovation projects implemented within three sub-sectors of the primary industry sector in New Zealand.

Design/methodology/approach: The characteristics that fostered co-innovation in each innovation project case study were identified from semi-structured interviews conducted with key stakeholders in each project, iterative discussions to confirm the findings and secondary document analysis. Common themes from the three cases are examined in relation to innovation system structure and function analysis and agricultural innovation system (AIS) literature. This study builds on the literature attempting to overcome methodological challenges in the applied AIS research space.

Findings: The findings have implications for co-innovation in practice; that there needs to be network-level capability and legitimacy, an understanding of priorities between actors, and adequate resources, to ensure proposed outcomes are likely to be attained.

Practical implications: Practically, project leaders need to ensure they embed an appropriate mix of actors in the research program and they also need to create and encourage room for open and honest dialogue between these actors to develop a shared vision of the future.

Theoretical implications: A conceptual model is developed to highlight and simplify lessons that can inform future projects involving co-innovation approaches to create value in the primary industries and AIS more generally. This model is unique to the applied AIS research space and provides new insights on enhancing the potential value of a co-innovation approach.

Originality/value: The paper adds to current scholarly debates and provides insight to key actions stakeholders need to take to foster co-innovation processes for successful outcomes in extension.  相似文献

Background: Researchers have indicated that assessment practices and methods should support learners’ construction of meaningful understanding of knowledge. Understanding students’ conceptions of assessment will enable us to construct more realistic, valid and fair assessments. Learners’ conceptualization of assessment would be imperative to serve as an essential reference to evaluate their learning progress.

Purpose: This study evaluated and compared the Singaporean and Taiwanese middle school students’ conceptions of science assessment. Within-country gender comparisons were also explored.

Sample: 424 Taiwanese and 333 Singaporean eighth graders were invited for a cross-country comparison.

Design and methods: The participants completed a questionnaire named Conceptions of Science Assessment.

Results: The findings showed that the summative assessment dominates in the Taiwanese classrooms, while formative and summative assessment are usually perceived in Singaporean classrooms. The Singaporean students had a greater tendency than their Taiwanese counterparts to perceive the purpose of assessment as a way of reproducing knowledge, and the formative assessment as improving learning, problem-solving, and critical judgment. No gender differences were found among either the Singaporean or the Taiwanese students.

Conclusions: Educators in both countries should provide learners with more opportunities to experience process-oriented science assessment activities and de-emphasize the usage of examination-oriented practices to achieve the sophistication of conceptions.  相似文献

Background: Many international science curriculum documents mandate that students should be able to participate in argument, debate and decision-making about contemporary science issues affecting society. Termed socioscientific issues, these topics provide students with opportunities to use their scientific knowledge to discuss, debate and defend their decisions and to evaluate the arguments of their peers.

Purpose: This study describes the development and trialling of scenarios based on the socioscientific issue of climate change. The scenarios required students to make and justify a decision and were designed to assess students’ argumentation skills.

Sample: A sample of 162 Year 10 students from five schools in Perth, Western Australia participated in this study.

Design and methods: Recent media articles were reviewed to identify relevant contexts for scenarios related to climate change that could be used to develop and assess students’ argumentation skills. In the first phase, students trialled scenarios about wind farms and hydrogen fuel buses using writing frames with scaffolding questions to generate as many reasons as possible to justify their decision. The responses were categorised into themes which were used to prepare a scoring rubric. In the second phase, students generated written arguments about the scenarios to support their decision. The arguments were analysed using both the scoring rubric developed from the first phase and Toulmin’s argumentation pattern of claim, data, backing, qualifier and rebuttal.

Results: Students’ responses to the scaffolded questions were categorised into themes of agriculture, economy, energy, environment, human impact and ethical factors. The themes of economy and the environment predominated with ethical justifications cited infrequently. An analysis of the arguments generated revealed a majority of students’ responses consisted of a claim and data with backings, qualifiers and rebuttals rarely provided.

Conclusions: Scenarios about climate change socioscientific issues can be used by teachers to both develop and assess students’ argumentation skills in classroom settings.  相似文献

Purpose: The key informants in a village setup were studied to understand the existing social and knowledge systems of farmers, their structure, and relationships between different actors. The purpose is to identify different channels of information and use them as a means to disseminate agricultural technologies and related information to farmers.

Design: We use the network map analysis in a case study approach as a tool to demonstrate the linkages between the key actors and stakeholders in the information network of farmers.

Findings: The government institutions are well networked among themselves but have limited interactions with non-government sources. Farmers in Bihar have strong linkages with few network actors, who are important nodes in the social knowledge network. The study showed heterogeneity and complexity in the network shape and structure across different districts.

Practical Implications: Knowledge networks and social networks are the drivers of information sharing and play a significant role in the diffusion of agricultural technology and related knowledge. Understanding these networks provides a platform for introducing the agricultural technologies and getting connected to a wider group of farming communities.

Theoretical Implications: The study shows that the network is formed by different actors and their role determine the nature and shape of the network. Knowledge of this heterogeneity is important in designing or revamping agricultural information systems.

Originality: Information and knowledge networks are least explored in the agricultural information dissemination process. Some studies have shown the role of actors and social networks, but this study uniquely explores and presents the heterogeneity of these networks.  相似文献

Background: Numerous studies have been conducted to investigate the factors related to science achievement. In these studies, the classroom goal structure perceptions, engagement, and self-efficacy of the students have emerged as important factors to be examined in relation to students’ science achievement.

Purpose: This study examines the relationships between classroom goal structure perception variables (motivating tasks, autonomy support, and mastery evaluation), engagement (behavioral, emotional, cognitive, and agentic engagement), self-efficacy, and science achievement.

Sample: The study participants included 744 seventh-grade students from 9 public schools in two districts of Gaziantep in Turkey.

Design and methods: Data were collected through the administration of four instruments: Survey of Classroom Goals Structures, Engagement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. The obtained data were subjected to path analysis to test the proposed model.

Results: Students’ perceptions of classroom goal structures (i.e. motivating tasks, autonomy support, and mastery evaluation) were found to be significant predictors of their self-efficacy. Autonomy support was observed to be positively linked to all aspects of engagement, while motivating tasks were found to be related only to cognitive engagement. In addition, mastery evaluation was shown to be positively linked to engagement variables, except for cognitive engagement, and self-efficacy and engagement (i.e. behavioral, emotional, and cognitive engagement) were observed to be significant predictors of science achievement. Finally, results revealed reciprocal relations among engagement variables, except for agentic engagement.

Conclusions: Students who perceive mastery goal structures tend to show higher levels of engagement and self-efficacy in science classes. The study found that students who have high self-efficacy and who are behaviorally, emotionally, and cognitively engaged are more successful in science classes. Accordingly, it is recommended that science teachers utilize inquiry-based and hands-on science activities in science classes and focus on the personal improvement of the students. Furthermore, it is also recommended that they provide students with opportunities to make their own choices and decisions and to control their own actions in science classes.  相似文献

Purpose: This paper reports the results of survey research conducted with tribal producers between 2011 and 2012 on 19 of the largest American Indian reservations in Idaho, Nevada, North Dakota, Oregon, South Dakota, and Washington. The purpose of the research was to identify potential barriers to sustainable agriculture on reservation lands. This article reports the results of this research in an effort to promote Extension professionals' understanding of these barriers, which may help to improve outreach programs on American Indian reservations. Understanding the obstacles to sustaining agriculture that American Indian tribes face may inform international agricultural outreach efforts to increase food security targeting indigenous and tribal peoples worldwide.

Design/Methodology/Approach: American Indian agricultural producers comprised the study group. Study objectives included: (1) identify agricultural and natural resource issues of greatest concern to a self-selected sample of tribal agricultural producers on reservation lands; (2) evaluate access to Extension and other US Department of Agriculture outreach and assistance programs; and (3) evaluate the quality of these programs in terms of their relativity to tribal needs.

Findings: Study results indicate that tribal agricultural producers surveyed ranked 29 of 39 agricultural and natural resource issues as a concern. Similarly, they rated access to and quality of outreach programs as fair. Further, tribal producers operating on reservation trust land rated issues more severely than did tribal producers operating on fee simple lands.

Practical Implications: Results of this research will help Extension and other outreach professionals to understand the barriers indigenous and tribal peoples face in sustaining agricultural operations, particularly tribal groups living on federally reserved trust lands, such as American Indians. An increased understanding can inform agricultural policy-makers and outreach professionals in improving programs designed to increase agricultural sustainability, improve food security, enhance economic well-being and improve quality of life of indigenous and tribal peoples worldwide.

Originality/Value: This research provides important information to agricultural policy-makers and Extension professionals striving to sustain agricultural productivity and enhance food security with indigenous and tribal peoples.  相似文献

Purpose: Replicating and extending earlier research, this mixed-methods study inquired about the characteristics of effective school leadership networks and the contribution of such networks to the development of individual and collective leaders’ professional capacities.

Design: The study used path analytic techniques with survey data provided by 283 school and district leaders to test a path model of effective network characteristics. Interview data were provided by 23 school leaders. Variables in the model included Network leadership, structure, health, connectivity, and outcomes.

Findings: Results confirmed that the model was a very good fit with the data and, as a whole, explained 51% of the variation in network outcomes. Network leadership had the largest total effect on network outcomes, followed closely by the effects of Network Health and Network Connectivity. Interview data confirmed the nature of variables measured by the survey and added additional features for future research. Most results replicated the previous study.

Research Limitation: The study was limited to leadership networks intentionally organised within districts, not networks organised by school leaders themselves or networks arising spontaneously by their members. Results cannot be generalised to other types of networks.

Practical implication: In addition to a focus on single unit leadership development in districts, systematic initiatives should be designed to help prepare network leaders to foster the forms of collaboration that are so central to professional capacity development.

Originality: Results of the study offer explicit guidance to network leaders about how to improve the contribution of network participation to their colleagues’ capacities; it is one of a very small number studies in educational contexts to provide such guidance.  相似文献

Background: Substantial research highlights the differences between scientific and technological knowledge. Considering that learning is heavily focused on the acquisition of knowledge, it is important to examine the individual and systematic implications of these types of knowledge.

Purpose: The purpose of this study was to examine the impact on overall educational performance as a result of engaging with technology subjects at post-primary level.

Sample: A five year cohort study was designed to gather longitudinal data from a total sample of 1761 pupils’ grades from the Irish Leaving Certificate examination. The sample was distributed across four schools.

Design and methods: Grades from the Irish Leaving Certificate were selected because the examination is considered high stakes as it serves as the country’s primary mechanism for matriculation into third-level education. Individual examinations are designed externally to schools by a government body ensuring the validity of each examination in capturing the holistic interpretation subject syllabi. Finally, a points system is used to score each examination facilitating comparisons between subjects.

Results: The results show that pupils who study the technology subjects are statistically significantly less likely to perform well overall in comparison to pupils who study science and mathematics subjects. They also show that for pupils who study the technology subjects, those subjects are statistically significantly likely to be their best performing subjects.

Conclusions: Due to the array of variables impacting subject selection, a definitive causal explanation cannot be deduced from the data for these results. However, it is possible to infer that the variance in knowledge types between the science and technology subjects has an impact on the results. A case is made that a compulsory technological component should be incorporated into educational curricula to provide a comprehensive and general education and to facilitate the holistic development of pupils.  相似文献

Purpose: Educational methods to diagnose and improve the level of environmental conception are required. The present work reports a methodology based on studies about the environmental perception of a university public, divided into general students and those related to the forest sciences, who are involved with disciplines and researches related to e.g. environmental management.

Design/Methodology/Approach: The environmental perception obtained from the graphical representation of environment and the most relevant actions indicated by the students to achieve the environmental conservation, divided in four levels of complexity, were correlated using principal component analysis.

Findings: The students from both groups having the highest scores in environmental perception prioritize actions related to the comprehension and responsibility levels, while the ideal scenario would be to indicate actions related to competence and citizenship. Thus, the complex concept about environment of the students is still incipient and, therefore, educational strategies can be traced based on the profiles obtained.

Practical Implications: The method for environmental perception can be designed for different populations and a scheme relating environmental perception with four levels of actions on behalf of the environmental conservation is proposed to diagnose environmental conceptions, as well as to guide educational strategies about socio-ecological system.

Originality/Value: A semi-quantitative method was developed to estimate, clearly and directly, the level of complexity about the environmental knowledge of university students and, consequently, to predict the actions on behalf of the environmental conservation that they would probably perform.  相似文献
