结合身体形态指标对体育终结成绩的回归评价

】体育教学中的成绩考核与评价是整个体育教学中的一个重要环节,目前学校一般仅仅根据学生通过某一阶段学习后终结考核成绩来进行的评价是不科学、不公平的。笔者采用回归评价的方法将终结成绩与身体形态指标结合起来进行评价,以便充分发挥评价的发展功能

The Media and Educational Testing: In Pursuit of the Truth or in Pursuit of a Good Story?

The measurement community needs to better understand how to interact with the media to effectively disseminate important findings from educational testing efforts. To this end, the current paper will review media coverage of educational testing and related issues and elaborate on areas of concern and opportunities for improved communication between measurement professionals and the media. Common misinterpretations of test results and measurement concepts will be discussed and suggestions for the clearer presentation and explanation of such information will be offered. Also, practical advice and strategies for handling different types of interactions with the media will be provided. The implications of focusing on this topic in the measurement profession and the inherent public value of this focus are highlighted throughout the paper.     

Evaluating the Comparability of Paper‐ and Computer‐Based Science Tests Across Sex and SES Subgroups

As access and reliance on technology continue to increase, so does the use of computerized testing for admissions, licensure/certification, and accountability exams. Nonetheless, full computer‐based test (CBT) implementation can be difficult due to limited resources. As a result, some testing programs offer both CBT and paper‐based test (PBT) administration formats. In such situations, evidence that scores obtained from different formats are comparable must be gathered. In this study, we illustrate how contemporary statistical methods can be used to provide evidence regarding the comparability of CBT and PBT scores at the total test score and item levels. Specifically, we looked at the invariance of test structure and item functioning across test administration mode across subgroups of students defined by SES and sex. Multiple replications of both confirmatory factor analysis and Rasch differential item functioning analyses were used to assess invariance at the factorial and item levels. Results revealed a unidimensional construct with moderate statistical support for strong factorial‐level invariance across SES subgroups, and moderate support of invariance across sex. Issues involved in applying these analyses to future evaluations of the comparability of scores from different versions of a test are discussed.

Validity Issues in Test Speededness

Speededness refers to the situation where the time limits on a standardized test do not allow substantial numbers of examinees to fully consider all test items. When tests are not intended to measure speed of responding, speededness introduces a severe threat to the validity of interpretations based on test scores. In this article, we describe test speededness, its potential threats to validity, and traditional and modern methods that can be used to assess the presence of speededness. We argue that more attention must be paid to this issue and that more research must be done to set appropriate time limits on power tests so that speed of responding does not interfere with the construct measured.     

不同运动等级青年男子乳酸阈、心肺功能的比较研究

选取体育专业足球队学生（专业组）、非体育专业不运动学生（对照组）和体育锻炼持续一年以上的学生（锻炼组）为实验对象，采用德国h／p／cosmos跑台和美国MAX-Ⅱ心肺测试系统等设备测定其在运动过程中心肺功能各指标及血乳酸浓度的变化并进行综合评价。结果显示，专业组和锻炼组达到乳酸阈时的跑速、血乳酸浓度高于对照组；乳酸闽和最大吸氧量（VO2max）时的摄氧量（VO2）、氧脉搏（O2P）、每分通气量（VE）、跑速等指标均高于对照组。     

统筹发展视野下“城乡教育”辨析——成都城乡教育统筹度评估体系研究（一）

文章从区域空间、受教育主体、价值取向三个角度,对“城乡教育”予以辨析。在此基础上,就城乡教育统筹实现度测评体系构建提出以下建议：应当根据教育的分布特征确定有区别的城乡教育划分标准;应当将城乡统筹过程中的农民工子女、留守儿童作为特殊人群予以关注;应当在测评中突出农村特色学校的价值。
