Digital Module 16: Longitudinal Data Analysis

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module begins with a nontechnical overview of longitudinal data analyses drawing distinctions with cross-sectional analyses in terms of research questions to be addressed. Nuances of longitudinal designs, timing of measurements, and the real possibility of missing data are then discussed. The three interconnected components of the LME model—(1) a model for individual and mean response profiles, (2) a model to characterize the covariation among the time-specific residuals, and (3) a set of models that summarize the extent that individual coefficients vary—are discussed in the context of the set of activities comprising an analysis. Finally, they demonstrate how to estimate the linear mixed effects model within an open-source environment (R). The digital module contains sample R code, diagnostic quiz questions, hands-on activities in R, curated resources, and a glossary.     

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.     

体育经纪人管理体制与运作机制研究

与国外体育经纪人管理体制比较，我国的体育经纪人立法管理“供给不足”。国外体育经纪人管理机构主要是国际和国家体育组织、国家和地方政府机构，以及体育经纪人行业协会。我国体育经纪人管理主要由国家体育总局各运动项目管理中心，以及地方体育和工商行政管理部门。目前的主要问题是：1)国家体育经纪人管理法规缺损；2)体育经纪资格征书的互认问题；3)体育经纪人培训考核规范问题。适合国情的立法体系是：“国家统一法规” “地方或行业配套法规”。管理体系是：“政府委托的协会监督” “行业自生的商会自律”。

<体育与健康课程标准>实施进程研究

经过反复的调查和对文献资料的分析，初步提出：体育与健康课程模式的多元化，是新“课标”由目标理念向操作化进程的有效途径。课程模式多元化，要以单元为基础，构建模块组合；以新“课标”为母体，构建子项模式；以新“课标”为依据，完善结构体系；以模式为中介，超越课程模式。     

中外体育保险之比较及我国体育保险的发展前景

随着桑兰在友好运动会严重受伤,王择秀在训练中意外死亡等事件的发生,体育保险逐渐成为体育行业的热点问题.虽然体育保险在中国还是新事物或新现象,但在体育发达国家中,对保证运动员的运动和生命安全起着极其重要的作用.通过资料的翻译和整理,以及数据分析,采访实际运作的公司和政府相关管理部门,描述了体育保险和保险经纪在中国的现状,以及在国外的发展状况.最后提出体育保险经纪在中国的发展前景.     

田径运动技术模式的研究

田径运动技术是指田径运动中符合人体运动科学原理、能充分发挥人体潜在能力,能有效地完成动作的合理方法、技能和手段,田径运动技术系统包括外在技术、身体技术、心理技术、社会技术和场地技术等几个部分,每个部分又包含不同的构成元素,各元素之间不同形式的联系形成了不同的田径运动技术模式.     

Implementing Problem-Based Learning in Principal Training： The First Pilot Program in China

In designing and implementing the pilot program of serving principal training, the author of this paper learnet the experience from what E. Bridges and E Hallinger did but didn＇t imitate fully, rather, created several new strategies because Chinese principals faced different situation from their American counterparts. The pilot program introduced and implemented the Problem-Based Learning （PBL） approach. The outcome of this pilot program shows： （1） PBL is a promising approach to serving principal training in China in casting off the traditional ＂chalk and talk＂ lecture approach. （2） The actual learning of trainees will happen prior to the classroom sessions if a trainer lets trainees participate the process of problem identification in pre-training stage. （3） PBL approach is much welcome and strong supported by local government and policymakers when the focal problem is related to implementation of current local nolicv.
