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

OBJECTIVE: Children who experience multiple victimizations (referred to in this paper as poly-victims) need to be identified because they are at particularly high risk of additional victimization and traumatic psychological effects. This paper compares alternative ways of identifying such children using questions from the Juvenile Victimization Questionnaire (JVQ). METHODS: The JVQ was administered in a national random digit dial telephone survey about the experiences of 2,030 children. The victimizations of children 10-17 years old were assessed through youth self-report on the JVQ and the victimizations of children 2-9 assessed through JVQ caregiver proxy report. RESULTS: Twenty-two percent of the children in this sample had experienced four or more different kinds of victimizations in separate incidents (what we term poly-victimization) within the previous year. Such poly-victimization was highly associated with traumatic symptomatology. Several ways of identifying poly-victims with the JVQ produced roughly equivalent results: a simple count using the 34 victimizations screeners, a count using a reduced set of only 12 screeners, and the original poly-victimization measure using follow-up questions to identify victimizations occurring during different episodes. CONCLUSION: Researchers and clinicians should be taking steps to identify poly-victims within the populations with which they work and have several alternative ways of doing so.  相似文献

ABSTRACT

With increasing moves globally towards the professionalisation of teaching in Higher Education, there is growing interest in the role of accredited professional recognition schemes that provide professional development for established university teaching staff. In the UK, There are now over 120 professional recognition schemes, resulting in institutionally focused evaluation studies examining their impact. This article contributes to this emerging body of work; it draws on cross-institutional data and Foucauldian theorising to address two important questions. In what ways does engagement with an institutional professional recognition scheme impact on participants’ teaching development, and how does institutional culture influence that engagement? The data illustrate that whilst institutional culture drives engagement, it did little to promote teaching development. Across the case-study institutions, neo-liberalism agendas were apparent. Some staff felt pushed to achieve professional recognition in response to the increasing use of metrics to measure the student experience and to inform institutional standing in league tables. Whilst evidence shows the process of seeking accreditation can lead to an enhancement in teaching practices, caution must be taken to ensure that the professional development opportunities offered by accreditation schemes are fully realised.  相似文献

Within the framework of Social Cognitive Career (SCCT; Lent, Brown, & Hackett, 1994, 2000), this study examined the associations among career interests, career efficacy expectations, gender, and perceived parent support among Native American and Caucasian middle school adolescents. Consistent with previous research, results indicated that Native American young people had greater interests in Realistic and Conventional occupations, and in occupations that typically require a high-school diploma, a trade school certificate, or 2 years of post high-school education. However, contrary to previous findings, they had as great a range of interests in and self-efficacy expectations for Investigative, Artistic, Social, and Enterprising occupations as Caucasian adolescents, and similarly high levels of interests, efficacy, and perceived parent support for careers typically requiring 4 or more years of post-high school education.  相似文献

Although equal sharing problems appear to support the development of fractions as multiplicative structures, very little work has examined how children's informal solutions reflect this possibility. The primary goal of this study was to analyze children's coordination of two quantities (number of people sharing and number of things being shared) in their solutions to equal sharing problems and to see to what extent this coordination was multiplicative. A secondary goal was to document children's solutions for equal sharing problems in which the quantities had a common factor (other than 1). Data consisted of problem-solving interviews with students in 1st, 3rd, 4th, and 5th grades (n=112). We found two major categories of strategies: (a) Parts Quantities strategies and (b) Ratio Quantities strategies. Parts quantities involved children's partitions of continuous units expressed in terms of the number of pieces that would be created. Ratio quantities involved children's creation of associated sets of discrete quantities. Within these strategies, children drew upon a range of relationships among fractions, ratio, multiplication, and division to mentally or physically manipulate quantities of sharers and things to produce exhaustive and equal partitions of the items. Additionally, we observed that problems that included number combinations with common factors elicited a wider range of whole-number knowledge and operations in children's strategies and therefore appeared to support richer interconnections than problems with relatively prime or more basic number combinations.  相似文献

The purpose of this study was to test the validity of the games for understanding model by comparing it to a technique approach to instruction and a control group. The technique method focused primarily on skill instruction where the skill taught initially was incorporated into a game at the end of each lesson. The games for understanding approach emphasized developing tactical awareness and decision making in small game situations. Two physical education specialists taught field hockey using these approaches for 15 lessons (45 min each). The control group did not receive any field hockey instruction. Data were collected from 71 middle school children. Pretests and posttests were administered for hockey knowledge, skill, and game performance. Separate analyses of variance or analyses of covariance were conducted to examine group differences for cognitive and skill outcomes. The games for understanding group scored significantly higher on passing decision making than the technique and control groups during posttest game play and significantly higher than the control group for declarative and procedural knowledge. The games for understanding group scored significantly higher on control and passing execution than the other groups during posttest game play. For hockey skill, there were no significant differences among the treatment groups for accuracy, but the technique group recorded faster times than the control group on the posttest.  相似文献

The current science education reform movement emphasizes the importance of professional development as a means of improving student science achievement. Reformers have developed a vision for professional development based upon intensive and sustained training around concrete tasks that is focused on subject‐matter knowledge, connected to specific standards for student performance, and embedded in a systemic context. Using data from a National Science Foundation Teacher Enhancement program called the Local Systemic Change initiative, this study employs hierarchical linear modeling to examine the relationship between professional development and the reformers' vision of teaching practice. The findings indicate that the quantity of professional development in which teachers participate is strongly linked with both inquiry‐based teaching practice and investigative classroom culture. At the individual level, teachers' content preparation also has a powerful influence on teaching practice and classroom culture. At the school level, school socioeconomic status was found to influence practice more substantially than either principal supportiveness or available resources. © 2000 John Wiley & Sons, Inc.

Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher‐educators alike. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 895–915, 2000  相似文献
