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

Background and context: The variables that researchers measure and how they measure them are central in any area of research, including computing education. Which research questions can be asked and how they are answered depends on measurement.

Objective: To summarize the commonly used variables and measurements in computing education and to compare them to best practices in measurement for human-subjects research.

Method: Systematic literature review analyzing 197 papers published during 2013–2017 in computing education research venues.

Findings: The review illuminates common practices related to: variables measured (including learner characteristics), measurements used, and type of data analysis. The paper lists standardized measurements that were used and highlights commonly used variables for which no standardized measures exist.

Implications: The paper concludes with information about best practices currently being used in the community that should be continued, as well as pointing out practices that could be improved along with recommendations for how to begin to adopt those best practices.  相似文献

The growing popularity of Social Networking Sites (SNS) that are embedded with networked infrastructures serves as an ideal platform for developing a networked learning environment connecting geographically dispersed learners. Unlike the traditional learning systems which provide only limited sources of data, the learners engaged in virtual networked social environments tend to produce huge volumes of digital footprints that cannot be analyzed using conventional analytical techniques. Two new branches of analytical sciences – Educational Data Mining (EDM) and Learning Analytics (LA) – are being employed for processing digital data derived from online educational platforms in order to obtain meaningful inferences and data-driven insights.

Hence, the present experimental study involving a small group of geographically dispersed learners intend to examine the engagement level and interaction patterns that occur within a feminist networked learning environment created in Facebook using popular EDM and learning analytical techniques such as K-means Clustering, Social network analysis and correlation mining. Upon analysis, it was found that the peer network influence played a vital role in activating passive learners, eventually leading to the development of a closely bound networked learning community over time.  相似文献

Background: Uncertainty is a crucial element of scientific knowledge growth. Students should have some understanding of how science knowledge is developed and why scientific conclusions are considered more or less certain than others. A component of the nature of science, it is considered an important aspect of science education and allows students to recognize the limitations of scientific research.

Purpose: This study examined Grades 5 and 9 students’ views of uncertainty in their personal scientific research and the formal scientific research of professionals.

Sample: This study included 33 students in Grade 5 (= 17) and Grade 9 (= 16). The students were recruited from a charter school that emphasised inquiry instruction.

Design and methods: Data were collected through interviews. Students were asked their views of their inquiry-based projects and their views of professional science.

Results: Interview data and statistical analyses indicated that students recognized uncertainty in personal science, which varied across elements of the scientific process. Additionally, their views of uncertainty in formal science tended to change across grades and knowledge of uncertainty in personal and formal science were positively correlated.

Conclusion: These findings offer insights into the processes by which students come to understand uncertainty in science and point to ways of fostering such knowledge through teaching practices.  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: Understand the emergence of new potential career trajectories in the liberalised Irish dairy farming sector through analysis of the narratives of students of a Professional Diploma in Dairy Farm Management

Design/methodology/approach: A review of the literature highlights that entry to a working life in agriculture has been characterised by protracted farm succession processes; a strong association between being a farmer and owning land in the family name; lingering male identities esteeming manual labour; and a pragmatic need at farm level for manual work. The abolition of milk quota in 2015 was predicted to catalyse expansion of production on dairy farms with an increase in milk production; accompanied by a demand for qualified personnel. The BNIM method was employed.

Findings: Results confirm that agricultural education is perceived and experienced as offering new pathways for young farmers to enter the occupational category of ‘farmer’, helping to manoeuvre around the constraints of non-inheritance. The students’ narratives evidenced managerial identities, being strongly influenced by encountering management approaches through their agricultural education. All students desired to eventually own a farm someday and to be to employed as a professional dairy farm manager was a perceived as an intermediary goal.

Practical implication: Discontinuation of the traditional family farming model based on family farm/land ownership is not imminent even among a cohort qualified to become employed dairy farm managers.

Theoretical implication: This paper contributes to theoretical framework which highlights the shift in farmer masculine identity and the career trajectory of graduates of specialised agricultural education programmes.  相似文献

Purpose: This study explores the use of advisory services by farm managers and its linkages with the economic, environmental and social performance of farms.

Design/methodology/approach: Using cluster analysis we determined groups of farms according to their sustainability performance and explored the correlations between contacts with advisory services and a set of farm-level sustainability indicators.

Findings: There exist significant differences in the number of farmers’ contacts with advisory services across countries, type of farms, farmers’ degree of agricultural education, utilized agricultural area, legal type of farm ownership and economic size of the farms. We identified three groups of farms that have different sustainability performance, are different in farm characteristics and relate differently to advisory services. The number of contacts with advisory services is positively related to the adoption of innovations, the number of information sources utilized and the adoption of farm risk management measures. We find no clear linear relationship between advisory services and environmental sustainability.

Theoretical implications: This study derives hypotheses to analyze causalities between indicators of farm-level sustainability and advisory services.

Practical implications: Results suggest the importance of taking into account the heterogeneity of farming systems for the design, targeting and evaluation of advisory services. In addition, results confirm the importance of selection of indicators that can be used in multiple sites.

Originality/value: We used a harmonized indicator of advisory services and a harmonized set of farm-level sustainability indicators in nine different EU countries that could be used to evaluate the role of advisory services in the achievement of multiple objectives in different groups of farms in multiple sites.  相似文献

Background: Despite the growing body of research on self-efficacy, previous studies have failed to clarify exactly how it is constructed. Meanwhile, the literature indicates that, in Taiwan, junior high school students tend to show lower self-efficacy in learning science compared with elementary and senior high school students.

Purpose: This study aimed to develop a mediational model providing the factors accounting for Taiwanese junior high school adolescents’ science learning self-efficacy (SLSE), especially from the perspectives of both interpersonal and intrapersonal factors.

Design: We therefore proposed a mediational model to delineate the relationships among students’ perceived responses to capitalization attempts – science learning (PRCA-SL), science learning hardiness (SLH) and SLSE by conducting structural equation modeling (SEM).

Sample: A total of 1,170 junior high school students in Taiwan were invited to take part in the study.

Results: The results confirmed our hypothesis that students’ PRCA-SL fostered their science learning hardiness, which in turn contributed to their science learning self-efficacy.

Conclusions: The findings confirmed the mediational model wherein science learning hardiness completely mediated the relationship between PRCA-SL and science learning self-efficacy.  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: Considering current debates on ecosystem services’ effectiveness and the AIS/AKIS functioning, in this study we suggest a new, systemic way to evaluate extension systems (ESs). Using this model, we compared the effectiveness of ESs in three countries with essential differences but also characteristic similarities in their agricultural sectors: Greece, Italy and Slovenia.

Design/methodology/approach: Initially, we defined ‘extension system’ as a wide range of actors integrating resources with the aim of co-producing value (not for but with) farmers. To capture the value flow within this constellation of actors we distinguished between the notion of ‘value in production’ – i.e. the value embodied in service offerings – and the value emanating when service content is used in real settings or ‘value in use.’

Findings: Our approach revealed that, despite their structural and organizational differences, the ES in the three countries share common problems arising from a limited focus on the issue of value in use.

Practical implications: The application of a systemic approach – seeing farmers as co-creators and not as end-users of extension services – in the evaluation of ESs contributes to better understand the complexity of value flow within the system and can strengthen extension systems’ effectiveness.

Theoretical implications: The present study, by reconsidering traditional evaluation approaches and by focusing on value co-production, offers an alternative value-centric framework for the conceptualization of extension services and points out to the need for refining the evaluation criteria of ESs.

Originality/value: Our work, by emphasizing the reciprocal creation of value within ESs, and by adding the concept of value in use, offers a new systems approach worth considering when evaluating ESs within different organizational and sociocultural contexts.  相似文献

Purpose: This study examined knowledge sharing mechanisms in coffee IPs and their effect on actor linkages in four districts of Uganda.

Design/methodology/approach: Thirty one respondents from the public and private sector were interviewed using a qualitative approach. Data were analyzed using the Atlas ti qualitative software version 7.5.18 to generate themes for information sources, types and channels. Social network analysis was used to measure the actor centrality positions and influence in the IP network.

Findings: Results revealed seven main categories of actors in the Coffee IPs who shared information on coffee inputs, agronomic practices, processing and markets through three main channels. Level of cohesion was less than 10% which had negative implications on the knowledge flow, trust and collaboration among the actors. Influential positions were occupied by the processors and farmer leaders in IPs in the southern districts of Luwero and Rakai, while nursery operators were most influential in IPs of the western districts of Ntungamo and Bushenyi. Weak linkages within the social networks indicated that initiatives of the actors were fragmented, as each actor acted as an individual detached from the platform activities limiting inter-actor knowledge sharing.

Practical implications: Innovation intermediaries should focus on integrated systemic and innovative approaches to strengthen actor social linkages for knowledge sharing and better platform performance.

Theoretical implications: Actor positions and relationships in innovation networks are critical tenets for fostering knowledge exchange and performance. In an innovation platform, diverse actors are multiple sources for accessing information within a given social and institutional context.

Originality/value: The study contributes to existing debate and knowledge on institutional change in agricultural innovation systems.  相似文献

Background and Context: Understanding the effects of learner characteristics and perceived learning environment on achievement in academic fields including Computer Science (CS) is of critical importance.

Objective: This study aimed at testing a hypothesized model of achievement in CS in terms of the learner and the learning environment characteristics.

Method: Data were collected using a questionnaire administered to a random sample of 315 eleventh and twelfth-grade advanced CS students (28% girls). Structural equation modelling (SEM) analysis was utilized to test the proposed structural model.

Findings: The hypothesized structural model fits the data reasonably, yet five of the 17 assumed effects were not significant. A modified model with only significant effects fit the data well and accounted for 41% of the variance. Mathematics achievement, self-efficacy and classroom learning environment are the most influential variables on achievement in CS.

Implications: The findings bear important implication for helping students by resolving obstacles that obstruct their learning and achievement.  相似文献

Purpose: The impact of agricultural knowledge transfer (KT) is related to the access to and the quality of services available. Within this context, the allocation of resources in terms of KT offices and the number of advisers are important considerations for understanding KT impact. This quantitative study evaluates the impact of KT resources on farm profitability for clients in Ireland during the recessionary period 2008–2014.

Design/Methodology: Teagasc, the public KT service provider in Ireland, experienced significant office closures (43%) and a reduction in advisers (38%) during the economic crisis, yet client numbers declined only slightly (4.5%). Administrative data are merged with a panel data set on farm-level performance to evaluate the impact through Random Effects estimation.

Findings: The results show that clients gained a 12.3% benefit to their margin per hectare over the period. However, there was a negative effect of 0.2% for each additional client assigned to the adviser which averaged at 9.6%.

Practical Implications: The quantitative findings provide a measure of impact that represents the value for money for the KT service. The key implication is that the client ratio for advisers should be considered when allocating resources and lower ratios would positively impact client margins.

Theoretical Implications: This article outlines the value of quantitative studies to estimate impact in a clear translatable manner which can aid the policy discussion around resource deployment.

Originality/Value: This study evaluates the impact of KT during a recessionary period when resources were constrained, and uses client ratios to examine the spatial effects.  相似文献

Purpose: To provide farmers with access to salient knowledge on sustainability that could contribute positively to farmers’ livelihoods, there is a need for knowledge facilitators. This paper examines the role of public extension workers as boundary workers in Indonesia on sustainable agriculture and challenges around them.

Design/methodology/approach: To identify sustainability perspectives, this research uses Q-methodology which analyzes individual perspectives on sustainability, their differences, and similarities. This research also employs focus group discussions and interviews. In three regions in Indonesia.

Findings: Q-method resulted in two perspectives. The technologists perceive sustainable agriculture as food security and the use of organic pesticides. They also believe that the responsibility for sustainable agriculture lies with extension workers and governments. The environmentalists believe the concept of sustainability implies the active prevention of environmental degradation. They also believe that everybody should take responsibility for sustainability. The paper determines that boundary work needs highly motivated extension workers; the ability to gain trust from farmers; and government support.

Theoretical implication: This paper contributes to the literature on boundary work by connecting the concept of boundary work to agricultural extension.

Practical implication: The results may be used as inputs for Indonesian policymakers to develop a guideline on sustainable agriculture for extension workers.

Originality/value: In current studies on extension workers in developing countries, an analytical framework which employs the concept of boundary work is hardly found. Boundary work is a relevant concept to depict challenges extension workers are confronted with when brokering. Q-methodology aims to obtain individual perspective on a particular issue. This research provides insight on individual perspectives of extension workers on sustainable agriculture.  相似文献

Purpose: This paper demystifies the processes, methodologies and outputs of three co-design projects, identifying how and to what extent are aims and principles of the multi-actor approach realised and upheld in the field. Implications from the cases for participatory principles are discussed.

Design/Methodology/approach: A detailed ethnographic account is presented of three multi-actor co-design cases, supporting diverse readers’ interpretations and learnings.

Findings: Three paradoxes were identifiable from the multi-actor processes: (1) outputs can be orphaned when they lack strong identifiers and affiliations with discrete professional communities outside of the co-design team; (2) combining diverse knowledges co-design can generate outputs that are new and strange (rather than familiar and acceptable) to end-users; (3) for Responsible Research and Innovation, co-creating interventions that are challenging (rather than popular) to society may be required.

Practical implications: Awareness of dynamics and paradoxes arising in the implementation of multi-actor co-design supports enhanced facilitation of processes and impacts of outcomes. Together, the paradoxes highlight the critical importance of communications and engagement initiatives across diverse communities in the aftermath of co-design efforts.

Theoretical implications: Although co-design processes are case-dependent, reflexive accounts of how they play out contribute to the body of knowledge of how co-design may be better understood. The cases in this paper identify paradoxes with implications for principles and theory of multi-actor co-design.

Originality/Value: This paper presents a detailed account of three unique co-design processes. Practical and theoretical implications of the cases are identified.  相似文献

Purpose: The study aims at finding out relevance and knowledge levels of selected teaching competencies as perceived by educational administrators, faculty and students, in order to assess the training needs of faculty of agricultural universities.

Methodology: Relevance and knowledge levels were tested through a teaching competency questionnaire developed and run on 292 respondents fitting into administrator, faculty and student groups. Needs Assessment Model by Borich [1980. “A Needs Assessment Model for Conducting Follow-up Studies.” Journal of Teacher Education 31 (3): 39–42] is used to identify training needs.

Findings: Results indicate differences in perceptions among groups towards teaching competencies. Prioritized training needs were identified which provide the content and direction for the development of faculty in-service educational programmes.

Practical implications: Faculty of agricultural universities need periodic in-service training programmes in order to improve their teaching competencies so that they become effective and competent teachers in the present educational environment.

Theoretical implications: The statistically validated methodological framework provides for capturing the perception of all stakeholders on the teaching competencies among the faculty members of Agricultural Universities in India, and offers a scope for scaling up the study for similar educational setting in the region.

Originality/value: The perception of students and administrators was also considered along with the self-perception of faculty about the relevance and knowledge levels of teaching competencies.  相似文献
