Rater Certification Tests: A Psychometric Approach

Rater training is an important part of developing and conducting large‐scale constructed‐response assessments. As part of this process, candidate raters have to pass a certification test to confirm that they are able to score consistently and accurately before they begin scoring operationally. Moreover, many assessment programs require raters to pass a calibration test before every scoring shift. To support the high‐stakes decisions made on the basis of rater certification tests, a psychometric approach for their development, analysis, and use is proposed. The circumstances and uses of these tests suggest that they are expected to have relatively low reliability. This expectation is supported by empirical data. Implications for the development and use of these tests to ensure their quality are discussed.     

Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

Professional development on fostering students’ academic language proficiency across the curriculum—A meta-analysis of its impact on teachers’ cognition and teaching practices

This meta-analysis aggregates effects from 10 studies evaluating professional development interventions aimed at qualifying in-service teachers to support their students in mastering academic language skills while teaching their respective subject areas. The analysis of a subset of studies revealed a small non-significant weighted training effect on teachers’ cognition (g’ = 0.21, SE = 0.14). An effect aggregation including all studies (with 650 teachers) revealed a medium to large weighted overall effect on teachers’ classroom practices (g’ = 0.71, SE = 0.16). Methodological variables moderated the effect magnitude. Nevertheless, the results suggest professional development is beneficial for improving teachers’ practice.

6周功能性力量训练对优秀女子赛艇运动员身体功能性动作的影响

目的：通过对备战2016年里约奥运会的国家赛艇队12名公开级女子双桨组运动员6周功能性力量训练前后功能动作筛查测试（FMS）成绩进行动作质量的比较，探讨功能性力量训练对运动员身体功能动作质量的影响，以便为今后备战比赛过程中制定提高运动员动作质量和运动技巧的功能性力量训练计划提供参考；方法：选取12名优秀女子赛艇运动员为研究对象，对研究对象在云南会泽高原训练基地训练期间进行6周功能性力量训练干预，并在实验前后对运动员FMS 测试的7个评价身体功能动作的得分进行比较；结果：6周功能性力量训练后，运动员各指标得分平均提高为深蹲0.7分、跨栏架步1.3分、直线弓箭步0.9分和躯干稳定性俯卧撑1.1分，4个动作得分较实验前都显著提高（P<0.05），而肩关节灵活性、主动直膝抬腿、旋转稳定性3个动作的得分较实验前无显著差异（P＞0.05）；结论：6周的功能性力量训练有效地改善了运动员做深蹲、跨栏架步、直线弓箭步和躯干稳定性俯卧撑功能动作等的动作模式，表明采用的功能性力量训练计划科学合理，可为今后备战比赛过程中运动员功能性力量训练计划的制定提供参考。     

Improving cognitive and physical function through 12-weeks of resistance training in older adults: Randomized controlled trial

ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.
