Purpose: This paper examines the benefits of using an outcome-based education (OBE) method within agricultural extension outreach programmes for professional and farmer audiences. Design/Methodology/Approach: The method is elaborated through two practical examples, which show that focused, short-duration programmes can produce meaningful skill development and impacts at the farm level. Both examples addressed pressing problems that were evolving during the education programme, and we sought a method that would respond adaptively to local circumstances and unanticipated changes. Key aspects of the method include strategic planning to properly focus education programmes, and the integration of data-driven decision support tool development to reduce uncertainty associated with the use of high-risk pest management inputs. Findings: Professionals and farmers increased their knowledge and skills related to pesticide management, and follow-up evaluation documented high levels of adoption of risk reduction and mitigation practices by farmers. Practical Implications: We recommend OBE for several reasons: (1) it uses a group process to elicit an accurate view of the system that learners operate within, (2) it provides cohesive and active learning with the potential for continuation, and (3) it enables feedback between all stages of programme development and implementation. Originality/Value: The most novel aspect of our adaptation of the OBE approach is the integration of, and feedback between, participatory programme design and tool development throughout the process, which maximises the value of each, and their ability to deliver outcomes. The OBE method integrates science, technology and social learning, and connects these with authentic problem-solving tasks to perpetuate learning beyond the classroom to where outcomes are attained. 相似文献

Effective health care with older adults requires that clinicians and practitioners are knowledgeable about aging issues and have the skills to work within an interdisciplinary team context. This article describes a Senior Mentoring Program that paired clinical students in medicine, nursing, and a physician assistant program with community-dwelling seniors for regular interactions. This interprofessional education experience included graduate gerontology students as discussion facilitators. Because including gerontology students as Interprofessional Dialogue Facilitators (IDFs) was an innovative aspect of the program, their participation within interdisciplinary groups was analyzed. IDFs monitored a secure internet site where clinical students discussed their experiences with their mentors. Discussion posts by the IDFs were clustered into three major types: amplifying statements that stimulated and furthered dialogue, augmenting posts that integrated specialized content on aging within the discussions, and analyzing comments that helped students reflect on experiences from different perspectives. The advantages of including aging content experts, such as gerontology students, within aging awareness activities like Seminar Mentoring programs are discussed. 相似文献

How much students feel at home in school predicts academic outcomes. In view of the gender achievement gap, it is worth examining the gendered pattern of this school belonging. Studies on school belonging, however, have barely acknowledged possible obstructive effects of traditional gender role attitudes of individual students and student cultures. This study examines the relationship between gender role attitudes and a sense of school belonging among a sample of 6380 students from 59 Flemish schools at the start of their secondary education. The results of multilevel analyses indicate that boys show less sense of school belonging than girls, as do students with more traditional beliefs about gender roles. Moreover, student attitudes related to gender roles are strongly shared at the school level, so that we can speak of a gender role student culture. Students enrolled in more traditional gender role student cultures reveal less school belonging. 相似文献

Two studies (conducted in 2013) examined whether elementary‐aged children endorse a within‐gender stereotype about sexualized girls. In Study 1, children (N = 208) ages 6–11 rated sexualized girls as more popular but less intelligent, athletic, and nice compared to nonsexualized girls. These distinctions were stronger for girls and older children, and in accordance with our developmental intergroup theoretical framework, were related to children's cognitive development and media exposure. Study 2 (N = 155) replicated the previous findings using more ecologically valid and realistic images of girls and further explored individual differences in the endorsement of the sexualized girl stereotype. Additional results indicated that the belief that girls should be appearance focused predicted their endorsement of the sexualized girl stereotype. 相似文献

This study examined the neurobiology of maternal sensitivity to children's emotions among mothers involved with Child Protective Services (CPS) and low‐risk comparison mothers (Mage = 31.6 years). CPS‐referred mothers participated in the Attachment and Biobehavioral Catch‐up (ABC) intervention or a control intervention. Mothers' event‐related potentials (ERPs) were measured while they categorized images of children with crying, laughing, and neutral expressions. CPS‐referred ABC mothers (n = 19) and low‐risk comparison mothers (n = 30) showed a larger enhancement of ERP responses for emotional faces relative to neutral faces than CPS‐referred control mothers (n = 21). Additionally, the magnitude of ERP responses to emotional faces was associated with observed maternal sensitivity. Findings add to the understanding of the neurobiology of deficits in parenting and suggest that these deficits are changeable through a parenting intervention. 相似文献

This study aimed at translating the physical activity (PA) guideline (180 min of total PA per day) into a step count target in preschoolers. 535 Flemish preschoolers (mean age: 4.41 ± 0.58) wore an ActiGraph accelerometer (GT1M, GT3X and GT3X+) – with activated step count function – for four consecutive days. The step count target was calculated from the accelerometer output using a regression equation, applying four different cut-points for light-to-vigorous PA: Pate, Evenson, Reilly, and Van Cauwenberghe. The present analysis showed that 180 min of total PA per day is equivalent to the following step count targets: 5,274 steps/day using the Pate cut-point, 4,653 steps/day using the Evenson cut-point, 11,379 steps/day using the Reilly cut-point and 13,326 steps/day using the Van Cauwenberghe cut-point. Future studies should focus on achieving consensus on which cut-points to use in preschoolers before a definite step count target in preschoolers can be proposed. Until then, we propose to use a provisional step count target of 11,500 steps/day as this step count target is attainable, realistic and helpful in promoting preschoolers’ PA. 相似文献

Successful project management can lead to improved effectiveness and efficiency in technical services and large-scale collection management. Using project management as a tool helps academic research libraries find overlapping objectives, maximize staffing resources, and accomplish large goals that would otherwise not be possible given ongoing financial constraints. By thinking creatively about the intersection of short-term projects and long-term needs, librarians will be better able to enhance access to collections in meaningful and timely ways. 相似文献

An analysis of 582 film titles spanning the years from 1980 to 2010 was conducted to examine the attributes and characteristics that predicted both viewership (e.g., box-office revenues) and critical acclaim (e.g., awards, audience ratings). Overall, viewership was highest for action/adventure films and lowest for dramas. In contrast, acclaim was highest for more dramatic fare, and for films that featured dark, contemplative, and emotional themes. The results are discussed in terms of the entertainment gratifications reflecting both enjoyment and appreciation. 相似文献
