大学体育课程教学模式设计与动作探讨   总被引:3,自引:0,他引:3  
张炎 《四川体育科学》2003,(4):74-75,78
本丈参照2002年教育部新颁布的《全国普通高等学校体育课程教学指导纲要》,针对目前高校体育发展的现状,围绕“生活体育、体育生活”这一思路,就体育如何真正走入大学生生活及高校体育与社会体育接轨等问题提出新的操作思路,设计了“一年级选项课 二年级课外教学俱乐部 高年级选修课 全方位体育俱乐部”这一模式。旨在为全国大多数尚未启动或即将启动的高校体育课程教学改革提供借鉴和参考。  相似文献

Failure Modes and Effects Analysis (FMEA) is a proactive assessment tool originally created for quality assurance in manufacturing industries. FMEA involves the assignment of rankings for frequency, severity, and detection of errors within a process. Catalogers at ProQuest undertook an innovative project to use FMEA to evaluate MARC record production. This article provides an overview of FMEA for process evaluation and summarizes an application for cataloging. It considers the tool's value for error-proofing in MARC record creation and how FMEA might be applied more effectively in a variable environment.  相似文献

The primary purpose of this research was to examine the construct validity of the Child Abuse Potential Inventory by comparing maltreating and high-risk parents' CAP Inventory abuse scores to their behavior during interactions with their children. A second purpose was to determine the degree to which CAP Inventory scores and parenting behavior were related to several known correlates of abuse, as measured by parent and teacher reports. Participants (n = 41) included abusive and high-risk parents and their children referred to a treatment group. Correlational analyses revealed that CAP Inventory scores and observed parenting style yielded highly related findings, supporting construct validity of the CAP Inventory. However, the CAP Inventory and observed behavior index showed a different pattern of relationships to the risk correlates. Implications for assessment of risk status are discussed and recommendations are provided for continued research.  相似文献

Known as the ‘third polar region’, the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there. Previous studies of birds, animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence. The adaptive processes during the initial phase of highland adaptation remain poorly understood. We studied a human commensal, the Eurasian Tree Sparrow, which has followed human agriculture to the Qinghai-Tibet Plateau. Despite strong phenotypic differentiation at multiple levels, in particular in muscle-related phenotypes, highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years. In a one-month acclimation experiment investigating phenotypic plasticity, we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes. Through population genetic analyses, we identified a signature of polygenic adaptation, whereby shifts in allele frequencies are spread across multiple loci, many of which are associated with muscle-related processes. Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution, shedding light on early stages of adaptive evolution to a novel environment.  相似文献

Although the presence of toys in childhood has remained steady for decades, the types of toys that fill children's toy boxes have changed, especially over the last 10–15 years. Many of today's toys are marked by technological enhancements, from a shape sorter driven by a singing bear to robotic plastic animals designed to match a toddler's favorite television show. Although examining the effects of these changes is still an unexplored area, research to date suggests that there may be costs to the quality of caregiver–child interaction when using these toys together. This leads to two possibilities: (1) the design of the enhancements themselves hurt interactions; or (2) these toys can still be beneficial to interactions, but caregivers simply need to be aware of the potential pitfalls. In this study, we explore whether providing caregivers with a subtle cue about the potential negative impacts of technological toys on caregiver–child interaction affects their behavior.  相似文献
