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

Victoria A. Roach  Graham M. Fraser  James H. Kryklywy  Derek G.V. Mitchell  Timothy D. Wilson 《Anatomical sciences education》2019,12(1):32-42

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.

定向行走课程与教学专业能力研究     

杞昭安 《现代特殊教育》2020,(2):26-37

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献

Impact of combining data from multiple instruments on performance of patient-based real-time quality control     

Qianqian Zhou  Tze Ping Loh  Tony Badrick  Chun Yee Lim 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(2)

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献   

高职体育教学中学生体育素养和职业能力培养研究     

崔柯 《当代体育科技》2020,(10):137-138

高职教育是我国高等教育的重要组成部分,高职院校专注培养实用型人才,重视学生的实际运用能力,以及实际操作能力,满足社会对实用技能型人才的需求。随着教育体制的改革,传统体育教学中的问题不断凸显,很难培养学生的体育素养,也不利于提升学生的职业能力。高职院校在体育教学中,不仅要教授学生专业的体育知识,也要将学生的身体素质和职业技能作为重要的教学内容,针对学生的专业制定体育项目,促进学生体育能力的多方面发展,为未来的社会工作作铺垫。目前高职院校在体育教学中,忽视学生体育素养和职业能力的培养,需要及时改进,制定合理的措施,提升学生的体育素养和职业能力。  相似文献   

Power training in elite young soccer players: Effects of using loads above or below the optimum power zone

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献   

人本关怀理念下普通高校体育课程改革探究     

戴飞 《体育科技文献通报》2020,(2):45-47

在升学与就业的双重压力下,无论学校、教师还是大学生本人都对普通高校体育课程存在不同程度的忽视心理与忽视行为。从体育课程的教学形式、教学内容、教学时长来看,并没有起到促进大学生综合素质提升的作用,也没有对高等教育体系完善做出应有的贡献。而在教学过程中,大学生的个人意愿、学习的主观能动性也没有得到挖掘与激发。可以说,大学体育课程缺乏以人为本的教学理念。这些问题成为大学体育课程亟待改革的弊端。  相似文献
