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.

“I'm just not that great at science”: Science self-efficacy in arts and communication students     

Eileen McBride  W. Wyatt Oswald  Lindsey A. Beck  Amy Vashlishan Murray 《科学教学研究杂志》2020,57(4):597-622

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment.  相似文献   

瑞士法框架下体育仲裁“裁决修正”探讨     

熊瑛子 《武汉体育学院学报》2020,54(6):39-45

瑞士联邦最高法院将裁决修正适用于国际仲裁的先例，使得这一原本属于瑞士国内法上的救济手段可以适用于国际仲裁中，体育纠纷大多属于国际仲裁的范畴。结合孙杨案件，对瑞士法框架下的体育仲裁"裁决修正"进行了探讨。研究认为，在瑞士法院的司法实践中，仲裁程序涉及刑事犯罪或裁决作出后发现新的民事证据，当事人均可申请瑞士联邦最高法院或其他各州地区法院修正仲裁裁决。刑事犯罪由于具备较强的司法公信力，容易在"裁决修正"中受到法院青睐，应当坚持刑事证据优先的原则。针对发现新的民事证据，需要满足时限条件、勤勉义务、重大影响和法律利益四项条件；同时排除一些禁止性规定才可能得到法院的支持。孙杨案件若以裁决修正理由继续上诉，获得胜诉判决的可能性基本为零。  相似文献

拟定中国绿色设计标准通则          下载免费PDF全文

刘怡君  陈思佳  黄远 《中国科学院院刊》2016,31(5):499-507

国内外现行与绿色设计相关的标准,普遍存在着数量小、覆盖范围窄、标准涉及层次单一以及未形成统一和通用的标准体系等问题。基于此,文章提出了包含从范围到对象、再到原则的三维绿色设计标准目标框架。其中,范围指绿色设计的七大重点行业:能源、钢铁、有色、制造、交通、建筑、化工;对象指绿色设计的层次:宏观、中观、微观;原则指绿色设计的方法:生命周期、循环经济、产业生态学、社会网络分析和人因分析理论。基于三维目标框架,最终拟定了《中国绿色设计标准通则(草案)》。  相似文献
