大学生体测结果关注与锻炼坚持性关系的研究

探索大学生体测结果关注与锻炼坚持性的现状及其相互关系。通过文献法与访谈法对体测结果关注的概念及维度进行界定,自编大学生《体测结果关注问卷》,并修订大学生《锻炼坚持性问卷》,运用这两个问卷对1 219名在校大学生进行调查。通过方差分析、相关分析和回归分析,发现大学生的体测结果关注与锻炼坚持性在性别、年级方面存在显著差异,体测结果关注与锻炼坚持性显著相关,体测结果关注可以预测锻炼坚持性。其中,体测自较关注是预测锻炼坚持性及努力投入与情感体验因子的主导因素,《标准》评价关注最能预测锻炼行为。研究发现了体测自较关注对锻炼坚持性的重要意义,建议在实践教学中不仅要通过结果性评价满足学生对《标准》评价的关注,更要重视通过体质增值评价提高学生对体测自较的关注,进而有效促进学生的锻炼坚持性。研究为大学生体质健康促进的教学干预提供了理论依据。

Superior short-term learning effect of visual and sensory organisation ability when sensory information is unreliable in adolescent rhythmic gymnasts

Rhythmic gymnasts specialise in dynamic balance under sensory conditions of numerous somatosensory, visual, and vestibular stimulations. This study investigated whether adolescent rhythmic gymnasts are superior to peers in Sensory Organisation test (SOT) performance, which quantifies the ability to maintain standing balance in six sensory conditions, and explored whether they plateaued faster during familiarisation with the SOT. Three and six sessions of SOTs were administered to 15 female rhythmic gymnasts (15.0 ± 1.8 years) and matched peers (15.1 ± 2.1 years), respectively. The gymnasts were superior to their peers in terms of fitness measures, and their performance was better in the SOT equilibrium score when visual information was unreliable. The SOT learning effects were shown in more challenging sensory conditions between Sessions 1 and 2 and were equivalent in both groups; however, over time, the gymnasts gained marginally significant better visual ability and relied less on visual sense when unreliable. In conclusion, adolescent rhythmic gymnasts have generally the same sensory organisation ability and learning rates as their peers. However, when visual information is unreliable, they have superior sensory organisation ability and learn faster to rely less on visual sense.     

一个带协变量调整多响应比较的高效方法及其在基因组数据中的应用

目前在文献中有很多关于多响应比较的研究方法,但是对带协变量调整的非参数检验的研究较少。一种直观的想法是将数据先投影到协变量的正交空间中,然后再利用秩和检验、调整的秩和检验或最大值检验方法。但是,功效普遍不高。在调整的秩和检验和伪F检验两种方法基础上,构建MIN2检验。大量模拟和实际数据表明,MIN2检验的效果优于现有的非参数检验方法。

Pre-service teachers' implicit and explicit beliefs about English language learners: An implicit association test study

Pre-service teachers' attitudes and beliefs about English Learners (ELs) are especially critical as they enter their professions among an increasingly diverse student population. This study uses an Implicit Association Test to explore implicit and explicit beliefs and attitudes of pre-service teachers about ELs. Pre-service teachers from a Southeastern U.S. university hold generally positive implicit beliefs about ELs and express positive expectations for working with ELs and school support. Implicit association test measures have potential as tools for preparing pre-service teachers and evaluating the impact of interventions that seek to improve teachers’ readiness to serve this population.     

Difference score reliabilities within the RIAS-2 and WISC-V

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided.
