Teaching farms have recently gained popularity, but they are often expensive venues per student credit hour. It is therefore important they are used effectively. This research explored why faculty members use teaching farms, their goals and objectives with regard to the farm, and how they integrate teaching farms into curriculum. Twenty interviews were completed with faculty representing 15 institutions. A combined inductive and deductive approach was used to analyze data. The result was a typology of the roles of teaching farms in achieving educational goals and objectives. Four types of roles emerged: enhancement, competency, exploration, and foundation. Three of the four types reflect one of three models of higher education prevalent in the US. Our research suggests a better understanding of educational theory and pedagogy, combined with a firm appreciation of the different models of higher education could significantly enhance the quality of the learning experience provided on teaching farms. 相似文献

This paper describes an instructional development effort to create effective and compelling instruction for eCommerce students. Results from a small field study inform the development project. Four high school students in an eCommerce course completed the standalone tutorial developed to teach them how to create a web page in the HyperText Markup Language (HTML). The four participants were also interviewed in an attempt to determine what motivates them to learn. Researcher observations of completed web pages indicated that the tutorial helped the four participants learn introductory HTML tags and, except for one revealing instance, they mastered the content without instructor assistance. Future work to develop an automated system for determining and correcting learner misconceptions evident in dysfunctional hyperlinks would provide additional support to learners. Lastly, this paper discusses implications of the field study results for the design and implementation of effective and compelling instruction. 相似文献

This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient Faradaic reactions occurring at the electrodes when a DC-bias is applied. The DC biased AC electric field acting on this gradient generates a fluid flow in the form of vortexes. To understand more in depth the DC-biased ACEK flow mechanism, a phenomenological model is developed to study the effects of voltage, conductivity ratio, channel width, depth, and aspect ratio on the induced flow characteristics. It was found that flow velocity on the order of mm/s can be produced at higher voltage and conductivity ratio. Such rapid flow velocity is one of the highest reported in microsystems technology using electrokinetics. 相似文献

OBJECTIVE: This report describes the cascade of stressful events and secondary life changes experienced by parents in a case of alleged sexual abuse at a day care program. The study evaluated parents' Posttraumatic Stress Disorder (PTSD) symptoms and general psychological responses to the stressful events 4 years after the alleged abuse, and explored predictive factors of parental distress. METHODS: A total of 39 parents were interviewed about stressful events, life changes, and social support. Current distress reactions, psychological wellbeing, and locus of control were assessed with a battery of standardized measures. RESULTS: Hearing about the sexual abuse, testifying in court, hearing the verdict, and being exposed in media reports were all rated by the parents as distressing events. The majority of the parents experienced secondary life changes after the alleged sexual abuse. Four years after the alleged sexual abuse, one-third of the parents reported a high level of PTSD Intrusive symptoms and one-fourth reported a high level of PTSD Avoidance symptoms. There was a significant positive correlation between a measure of psychological wellbeing and PTSD. Secondary life changes and locus of control significantly predicted PTSD. CONCLUSION: This study demonstrates that the alleged sexual abuse of children in day care and the resulting events in the legal system and the media constitute significant and chronic stressors in the lives of the children's parents. These findings underscore the need to expand the focus of trauma-related sequelae from the child victim to their parents and family. 相似文献
