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: The current study has two goals. (1) Applying the DAST at a university in South Africa, the study will add to the existing research literature through its Southern African context. (2) The study will also look more closely at the link between (stereotypical) images of scientists and science-related career choices.
Sample: The DAST was applied to first-year students (n = 445) across different faculties at a South African university. If the assumption that young people’s perceptions of scientists influence their career choice is correct, one would expect differences in the drawings made by students who have opted for different fields of study.
Design and methods: The DAST was administered during orientation week of the first-year students in January 2017. Students were provided with a prepared blank sheet of paper and asked to draw a scientist and to fill in further information on the back of the paper. A content analysis applying the DAST checklist was used to analyse the images.
Results: The findings show that South African students use about four stereotypical indicators when drawing a scientist, and social science students drew stereotypical attributes more frequently when compared to students from other faculties. A typical scientist – as depicted in this study – is a man of uncertain age, who wears eyeglasses and a lab coat, and is surrounded by laboratory equipment.
Conclusions: Findings are largely in line with the international research literature. To challenge gender stereotypes, more contact between students and female role models might be essential. If (stereotypical) images really affect science-related career choices deserves further attention in future research studies. 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
Purpose: This qualitative case study investigates a primary science teacher’s TPACK development in the context of two interdependent learning spaces: a joint-school and a within-school professional learning community. The school’s organizational and sociocultural influences on teacher learning are also examined.
Participant: Teacher Sean (pseudonym) embarked on a science innovation project after two years of teaching in a Singapore mainstream school. He was tasked to integrate mobile-based inquiry learning and visible thinking pedagogical approaches, and to pilot the designed lessons for a primary three class.
Design and methods: A case-study approach involving multiple sources of data with cultural historical activity theory as the analytical lens was employed, to unpack the complementary and contradictory interactions across different interrelated activity systems. The purpose was to understand the (mis)alignments within and between the two professional learning communities.
Results: The findings indicate that Sean’s (subject) learning from the joint-school professional learning community to the within-school professional learning community faced multiple tensions that hindered his TPACK development (object). He faced difficulty in manipulating tools (technology and visible thinking routines) to translate the joint-school co-designed lessons into classroom implementation. Additionally, the volatility of the school’s organizational routines (rules) and the lack of communicative leader–teacher partnership (division of labor) did not afford sufficient infrastructure or instructional support.
Conclusions: Interactions between the teacher’s personal and contextual factors inhibited the designed TPACK from being implemented successfully. For ambitious pedagogical undertakings as illustrated in this case, more perceptive and synergistic organizational design thinking is needed to support beginning teachers’ TPACK development. 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: To identify the evolution of students’ conceptions regarding the nature of sound and its properties (frequency, intensity and frequency spectrum) through a teaching-learning sequence (TLS) about sound phenomena in an authentic musical context. The described TLS consists of three activities aiming students to correlate the properties of sound waves (frequency, intensity and frequency spectrum) with its perceptive characteristics (pitch, loudness and timbre) via the use of smartphone applications.
Sample: Eight students, in the second year of their studies in the Department of Primary Education of the XXX University.
Design and methods: Students’ perspectives on sound and their progression are investigated through a teaching experiment design. Data are collected by recording students’ interviews. Due to the explorative nature of the research qualitative methods of content analysis are used.
Results: The results show that the students’ perspectives on sound evolved, as students managed to consolidate links between their everyday experience of sounds and the underlying science concepts as frequency, intensity and frequency spectrum. The authentic environment and the use of the smartphone’s applications were key factors for the success of the teaching experiment. The interaction with the activities shifted student’s conceptualizations closer to the scientific ones, by communicating every day sound experiences with their scientific interpretation. 相似文献
Purpose: The purpose of this exploratory study is to investigate student perceptions in a Science Extended Curriculum Program (ECP) of both the traditional pen and paper method they used in 2016, and the new online resource method they used in 2017 to better prepare them for Physics laboratories, and to compare the two methods.
Sample: N = 51 students from a first-year Extended Curriculum Programme in physics at a South African university voluntarily participated in this study.
Design and methods: The research was conducted using two non-standardised structured questionnaires where the enrolled ECP students were asked both open-ended – and closed questions (using a Likert response scale). Google Forms using graphs assessed these responses. An additional source of data was iKamva/Sakai which is the University of Western Cape’s institutional Learning Management (LMS) system, which allowed for detailed information regarding online activities.
Results: Four main research questions focussing on preparedness, time spent, lab activities and online resources were identified. Findings from these suggest that an introduction of an online environment positively affected the students’ perceptions of the online environment for pre-laboratory preparation in comparison with using traditional pen and paper.
Conclusions: The present study has successfully managed to both reveal that the introduction of online environment for Physics laboratories brought about some positive benefits as perceived by the students, as well as fruitful avenues for future research. While more work is needed, in terms of research and continuing evaluation of eLearning in Physics education, there is reason to be positive in terms of renewed emphasis to add blended learning within the broader Physics learning and teaching communities. 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
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

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: 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: FFSs that are commonly used in guiding rural development processes involve a long process of preparation, weekly meetings and dissemination of new technologies with a greater knowledge flows from researchers or institutions to farmers than contrariwise. We have simplified FFS components and modified its curriculum focusing on extracting and integrating farmers’ feedback into adaptation measures. Surveys were conducted and their results were validated through focus group discussions, which provided an adequate database to simplify the steps in the FFS approach.
Findings: Only four meetings for agroecosystems analysis that emphasised an analytical and reflective learning cycle generated suitable adaptation measures selected from farmers’ feedback. Repetition of the shortened FFS over several rice cropping cycles proved more effective than the frequent meetings within one cropping cycle.
Practical implications: The modified FFS could be considered as a promising approach to training farmers, whilst simultaneously identifying and discovering adaptations of agricultural innovations and monitoring the evolution of complex polycultures like CRSs, under diverse conditions.
Theoretical implications: The modified FFS provides participants additional time to reflect on the training topics, resulting in a significant improvement in their knowledge and the performance of the CRS.
Originality/value: The modified FFS approach is focused on reflexive learning cycles and adaptation of innovations. Therefore, it is highly suitable for management of complex polycultures such as CRSs. 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
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
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
Method: Using grounded theory methodology, 12 participants were interviewed about the meanings and roles of valued material objects following a residential transition. Older adult participants lived in either their own home or a care home.
Results: The model entails two core categories, “threats to identity” and “objects and identity continuity” along with four explanatory concepts, “moving and identity discontinuity”, “connections across time”, “attachments to others”, and “preserving self and ancestors in the memories of the next generation”.
Discussion: Objects were described to have important personal meanings which helped people maintain a sense of identity continuity following residential transition. They were associated with comfort, security and life review processes, which support identity continuity later in life.
Conclusion: Moving house later in life can threaten a person’s sense of self. However, material objects can help maintain a sense of identity continuity through reminiscence and life review processes. Implications for community and residential care moving house transitions are discussed. 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
1. the subjects were ‘severely’ withdrawn/isolated children, and
2. the training sessions, unlike Ladd's fixed time schedule, continued until the subject's level of performance reached the level of ‘average’ peers in each targeted social skill.The findings indicated that the social learning method increased social interaction of ‘severely’ withdrawn/isolated children with their peers. However increasing their rate of behaviour in targeted social skills to the level of performance of their ‘average’ peers required approximately four times as many sessions of training as Ladd conducted with ‘mildly’ withdrawn/isolated children. 相似文献
