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 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   

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   

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: 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 (n = 17) and Grade 9 (n = 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   

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   

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   

Purpose: The purpose of this study was to identify preservice teachers’ ideas about how to increase students’ long-term interest in science.

Sample: The participants were 235 preservice primary teachers and 33 preservice secondary science teachers.

Design and Methods: Data collection was by questionnaire, interview and classroom observations.

Results: It was found that participants in both primary and secondary groups had very similar ideas about how to develop pupils’ long-term interest in science. These ideas mainly involved the use of hands-on activities, making science relevant, and using student-centred strategies or electronic media to make lessons fun and to enhance engagement. These can be interpreted as representing sources of situational interest (i.e. short-term interest arousal). These ideas broadly parallel the current theory on interest development, such that long-term individual interest is thought to develop from repeated experiences of short-term, situational interest.

Conclusion: The participants’ ideas in this study were intuitive, because they were not derived from an understanding of theory, but rather from their personal experiences of interest arousal at university, school and practicum. Nevertheless, their ideas were workable for a practitioner, because they broadly paralleled current theory on interest development.  相似文献   

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: This study explores STEM students’ encounters with an interdisciplinary first year. Specifically, motivational patterns towards learning in two introductory courses followed by students from multiple study programmes are investigated.

Sample: 173 Danish undergraduate students enrolled in three science programmes: biomedicine; biochemistry and molecular biology; and physics.

Design and methods: Within the framework of Self-Determination Theory, a measure of autonomous and controlled motivation forms the basis for quantitative analyses (n = 173). A qualitative thematic analysis of students’ open responses further supplements and gives nuance to the findings.

Results: The motivational pattern of physics students is found to differ significantly from that of biochemistry and molecular biology (BMB) students and biomedicine students. The comments reveal that some students struggle to realise the relevance of the course content for their chosen study programme to an extent that makes them reconsider their study choice.

Conclusions: The study offers input to the discussion of how to present inter- and/or multidisciplinarity to students and points to implications on two levels: curriculum design and course content. The findings are of importance to educational planners, decision-makers and teachers dealing with the motivational range that exists within their courses.  相似文献   

Design/Methodology/Approach: The analysis of the FADN potential relies on the classification of innovations and the co-identification, through the Most Significant Change (MSC) approach, of the most relevant indicators for tracking and assessing the performances of innovations and attributing to them the effects of a specific innovation.

Findings: The study shows that the FADN has a certain range of useful indicators and that they have a good coverage of the different types of innovation. Furthermore, the farm visits let emerge the importance of participatory approaches to capture the different changes and interplays occurred in farming processes.

Practical implications: The paper lays the foundations for the adaptation of the current methodology for data collecting and provides useful insights concerning the overcoming representativeness claims, costs’ issues, and problems related to the observation time limit.

Theoretical implications: The paper reveals the importance of participatory monitoring and evaluation approaches in helping the collection of more robust and relevant account data on farm, as well as in attributing certain results to a specific innovation and recognising synergies and side-effects of cooperative processes.

Originality/Values: The paper provides some recommendations on how to enlarge the scope of the FADN survey in order to be used effectively in the analysis of the performance of cooperative innovations at farm level.  相似文献   

Purpose: In this study, we investigated how students’ mental models about one-dimensional expansion can be extended for purposes of running mental simulations about expansion along two dimensions.

Sample: To that end a pretest-posttest quasi-experiment has been conducted, with 100 students in the control group and 95 students in the experimental group.

Design and methods: Whereas control group students received traditional instruction with a focus on formal representations, in the experimental group the students were led to draw an analogy between heating of a straight rod and a circular rod of same length, whereby the internal structure of the rods was represented by springs.

Results: Eventually, it has been found that students from the experimental group were significantly more successful at predicting the effects of thermal expansion, especially within contexts of objects with holes.

Conclusion: Analogies and extreme case reasoning can be effectively used for helping the students to correctly transfer their mental models about one-dimensional expansion to situations that require reasoning about expansion along two dimensions.  相似文献   

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   

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   

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   

Design/Methodology/Approach: The study engaged 30 farmers’ children in high school level from the provinces of Pangasinan, Isabela, Camarines Sur, Iloilo, Bukidnon, and Davao del Norte from November 2016 to October 2017. They interacted with the research team (the authors) and the RCM-SMS platform that sends text messages regarding fertilizer recommendations. A staff member from the Agricultural Training Institute (ATI) also called the students for some follow-up questions. The research team conducted three rounds of interviews with the students concerning the messages and calls that they received and what they did with the information.

Findings: This study finds that farmers’ children can perform infomediary roles quite effectively. Academically excellent children and those involved in farm work performed best.

Practical Implications: The study provides guidance on similar initiatives tapping young people in agricultural development.

Theoretical Implications: This paper finds that while Community Youth Development (CYD) Theory provides a powerful lens in understanding community and youth development intersections, some identified outcomes may overlap and may not be very easy to observe. Hence, the identified outcomes may be revisited for clarity and to make them more all-encompassing.

Originality/Value: The paper documents actual parent-child interaction when the latter is mobilized to serve as an infomediary to access nutrient management-related information on rice.  相似文献   

Objective: We explored the relationship between students’ first programming languages and both their final grades in an introductory computer science course and their attitudes about programming.

Method: Multiple matching techniques compared those whose first language was graphical (e.g., Scratch), textual (e.g., Java), or absent prior to college.

Findings: Having any prior programming experience had positive effects on both attitudes about programming and grades in introductory computer science courses. Importantly, students whose first language was graphical had higher grades than did students whose first language was textual, when the languages were introduced in or before early adolescent years.

Implications: Learning any computer language is better than learning none. If programming is to be taught to students before early adolescence, it is advised to start with a graphical language. Future work should investigate the transition between different types of programming languages.  相似文献   

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
