Aging and its effects on a person's quality of life are a growing health concern and burden for many Americans. Recently, studies have shown that adopting certain healthy behaviors may help maintain and or prevent age-related health issues such as cognitive decline. However, many people are unaware of these newfound facts. Furthermore, there is insufficient research evidence to understand how older adults view brain health and the differences between diverse groups of older adults. This study examines brain health knowledge and behaviors among Caucasian and African-American community-dwelling older adults in North Carolina. Findings were significant for level of education and total brain health knowledge scores, though there were no significant differences between races. In addition, there was a significant association between total number of health conditions and total brain health knowledge scores that warrants further study. 相似文献

In an effort to establish a baseline of technology competency among our entering education students, our College of Education began implementing the Assessment of Technology Competencies (ATC) in Fall 2003. This performance-based assessment evaluates word-processing, presentation, spreadsheet, graphic/drawing, and Internet skills. Although students are not required to pass the ATC, failure impacts their final grade in an Introduction to Education course. This paper explores the impact this assessment has had on the students' use and development of technology in subsequent courses. Student perceptions of the ATC and its impact were elicited through a self-reported survey administered in a junior-level education course. Results indicate that the ATC has facilitated technology use among the participants. Respondents also revealed that their high school experiences with technology adequately prepared them for passing the ATC, despite the fact that most students are unable to pass the ATC in the first attempt. 相似文献

This article discusses the development and implementation of a technology-supported student teacher performance assessment that supports integration with a larger electronic assessment system. The authors spearheaded a multidisciplinary team to develop a comprehensive performance assessment based on the Pathwise framework. The team collaborated with a third party vendor to implement and field test these assessments supported with mobile technologies in the field. Twenty supervisors completed the field test using 10 iPAQ PDAs and 10 laptops. Eighteen participated in a posttest survey and eight in a focus group debriefing session. Supervisors were overwhelmingly positive about the experience, the value of the updated assessments, and the ongoing plans to support field observations with mobile technologies. However, issues related to training, support, and trust loom largely for successful adoption, diffusion, and successful use of technology-supported assessments. 相似文献

Abstract Since the publication of the Crowther Report in 1959 there have been seven major proposals for reducing the degree of specialisation in England and Wales and postponing its onset. This article examines the history and nature of these proposals and the reasons for their failure. Its main contentions are that the historical opposition to any central or local control of the school curriculum has made it very difficult to determine what actually was happening in the schools or what external forces controlled the pattern of studies: and that in the absence of any authority controlling the pattern of the curriculum, it was almost impossible that any proposals for change would be implemented. 相似文献
