第9届健美操世锦赛中国队与冠军队三人操项目编排对比分析

对第9届健美操世界锦标赛中国队与冠军队三人操项目的编排对比分析表明：中国选手在难度动作分布的均衡性和难度级别在成套动作中出现的顺序不够合理,难度动作的级别也较低;动力性配合动作的编排较简单,配合时间短,没有空间体位的变化,缺乏亮点;托举动作的类型单一,缺乏创造性。     

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.

General and Specific Factors in Reading Comprehension

One explanation for why many students routinely choose to do their homework with a radio or TV operating is that this distraction facilitates studying. To investigate the validity of this explanation, the authors carried out two experiments with sixth-grade students who worked on two difficulty levels of individualized mathematics assignments (N = 12) and reading assignments (N = 9) under three distraction conditions: quiet; self-selected, self-regulated radio; and self-selected, self-regulated TV. The data yielded no evidence of sizable distractor effects on students' time spent studying, computational accuracy, reading comprehension, or reading rate. These results generally are consistent with the theoretical conceptualization of attention as flexible and adaptable.
