It can be argued that agricultural science is one of the original forms of science education. However, over the past century, agricultural science education has habitually been perceived as an educational venue meant solely for production agriculturalists. When examining modern agricultural education we find it to be a minority within the broader field of science education, contradicting its historically stout scientific standing within the sciences. This educational shift leaves one to ponder the historic development of contemporary agricultural education. To gain deeper insight into these questions we reviewed the historical evolution of agricultural education within the United States. We then examined the professional habitus, or cultural nuances, associated with contemporary agricultural education. Next, we considered potential outcomes associated with the profession embracing post-modern perspectives within mainstream science and community-based education. Finally, we call for critical venues within agriculture education to question the status quo and challenge the acceptance of commonly held views.  相似文献

Gender differences in academic performance and achievement have been of policy concern for decades—both interest in lower performance by girls in the areas of mathematics and science and, more recently, in boys' underperformance in most other academic areas. Much previous research has focused on gender gaps, while overlooking other factors that may play a role, such as ethnicity. This study looks at the gender differences in cognitive assessments at age five across ethnic groups in a sample of English children from the Millennium Cohort Study. While girls generally perform better than boys, general trends mask some differences across ethnic groups. Results show gender gaps at the mean are largest for black and Pakistani and Bangladeshi children and smallest for white children, they are also larger for the teacher‐rated assessments than for the survey‐administered tests.  相似文献

The purpose of this study is to explore the factors that prompt askers to switch from free to paid social question-and-answer (SQA) services. Prior studies have investigated users’ motivations and participation in free and paid SQA services; however, little attention has been paid to askers’ switching behavior. We empirically analyzed the content of qualitative interviews from 64 askers on a well-known SQA platform in China. Based on the push-pull-mooring framework, we identified and classified factors that influenced askers’ to switch from free to paid Q&A services, using the critical incident technique, after which we calculated the entropy weights of the 16 subcategories before and after the switch, using the entropy weight method. The findings suggest that askers’ switching behavior was influenced by push factors (i.e., dissatisfaction with the free SQA service), pull factors (i.e., satisfaction with the paid SQA service), and mooring factors (i.e., social factors, personal factors, situational factors). Moreover, the findings show that the effects of these factors vary significantly before and after a switch. Dissatisfaction with the quality of information from the free SQA service would influence users before a switch, whereas satisfaction with the quality of information from the paid SQA service would influence them after a switch. In terms of mooring factors, the effects of social and personal factors on askers’ switching behavior, especially subjective norms and cognitive lock-in, turn out to be less significant after a switch, whereas the effect of trust is more significant. Besides, the effects of situational factors are more or less the same before and after a switch. To the best of our knowledge, this paper is one of the first attempts to explore factors that affect askers’ switching behavior and to shed light on the managerial strategies of paid SQA services.  相似文献

Despite the rapid growth in the use of computers in organizations, few of the resulting systems have had a significant impact on the way in which management makes decisions. Frameworks are needed which aid in understanding the structure of management information systems, toward providing focus and improving the effectiveness of systems efforts.This paper surveys recent conceptual and empirical work related to development of decision-oriented frameworks for management information systems design, particularly as related to the improving the management of organizations.  相似文献

Faculty of the General College are assigned advising responsibilities in addition to their teaching load. Full-time members, for example, advise 35–40 students per year. When the College initiated an individualized baccalaureate degree program in 1971, little provision was made for consequent changes on the advising function and the academic load. As a result, advisers, faced with the complex and time-consuming matters that adhere to individualized learning programs, felt mounting pressure. Large numbers of evening school students were attracted to the program and sought advice and, upon admission, expected to be assigned a faculty adviser. The College made no formal acknowledgment of the addition of the non-day school advisees to advisers' loads. Strained by the overburden, faculty participated in this study to identify how much real time they spend in advising, with whom, and on what kinds of activities. Evidence from this study was used to support their request for recognition by the College of the changed nature and full scope of their advising work.The author wishes to acknowledge Drs. Paul J. Feltovich and Thomas Brothen for their help with the researching of this paper.  相似文献
