On teaching about the coefficient of variation in introductory statistics courses     

David Trafimow 《Teaching Statistics》2014,36(3):81-82

The standard deviation is related to the mean by virtue of the coefficient of variation. Teachers of statistics courses can make use of that fact to make the standard deviation more comprehensible for statistics students.  相似文献

Assessments to evaluate bilinguals: The overdue discussion of the deaf and hard of hearing student population in the United States     

Leala Holcomb  Gloshanda Lawyer 《Psychology in the schools》2020,57(3):426-442

Assessment is a major part of the United States schooling system. Legal requirements make assessment a large part of practitioner responsibilities. The significance of assessment is, even more, the case for special populations such as bilingual hearing and Deaf and Hard of Hearing students, groups that are often the target of concern for English language development delays, differences, and/or disorders. In this article, we discuss the issues around assessing the language of Deaf and Hard of Hearing bilingual students in the United States. We highlight parallels between Deaf Education and hearing bilingual education in regard to language assessment, as well as discuss important distinctions such as the placement of Deaf Education within Special Education and working with two or more language modalities (e.g., signed, spoken, and written). In addition, alternative language assessment practices are discussed. We close this article by proposing ways for practitioners to satisfy legal and field mandates to assess Deaf and Hard of Hearing students while also applying best practices for assessing language skills in bilingual populations.  相似文献

国际乒联频繁修改规则的批判性反思     

王翾  梁勤超  李林 《武汉体育学院学报》2020,54(10):88-94

采用文献资料等方法，梳理国际乒联21世纪以来的规则改革，反思其存在的问题。21世纪以来，国际乒联在器材、技术和赛制等方面进行了一系列的改革。一系列规则改革在技术上使得运动员技术选择和使用随意性增大，比赛胜负的偶然性增大；在国际乒坛秩序上产生了正、反两方面影响，一方面改变了中国队"一家独大"的局面，国际大赛的奖牌分布趋于多元化，另一方面，使得运动员打法逐渐呈现单一化趋势。同时国际乒联频繁修改规则还存在规则修改程序正义性、规则相对稳定性，以及权力行使过于随意等问题。要维系国际乒坛秩序的良性发展，国际乒联还需出台具体的规则改革制度，保证竞赛规则的相对稳定性，并合理行使规则修改的权力。  相似文献

体育侵权:自甘风险还是过失相抵     

李鼎 《武汉体育学院学报》2020,54(5):56-60

自甘风险和过失相抵是体育侵权案件中最常见的抗辩方式。前者将会免除加害人的赔偿责任,而后者只能按比例减少加害人的赔偿责任。虽然法律后果存在巨大差异,但目前对于体育侵权案件适用自甘风险,还是适用过失相抵,没有一个明确的标准,没有建构一套稳定的规则。从美国法的经验来看,通过对自甘风险进行分类来解决自甘风险和过失相抵的竞合问题,并不是一个成功的范例。实际上,自甘风险和过失相抵的主要区别在于受害人能否认知风险的存在。通过运动类型、违规程度、年龄和精神状况、参与的自愿性、专业程度等五个要素的综合考量,法官可以推知当事人的意思,进而从参加体育活动的行为来判断是否构成自甘风险,最终正确适用法律。  相似文献   

《放妻书》与现代离婚声明:塑造“人设”的媒介     

刘若衡  李晓愚 《传媒观察》2020,(5):51-58

《放妻书》是唐代敦煌地区出现的一种特别的离婚协议形式,它所反映的是一种唐代特有的"和离"制度,男女双方以"两愿离"的方式和平离婚。通过对《放妻书》文本的分析,本文阐明了《放妻书》可能的形成条件及其折射的唐代社会风貌。同时,基于对《放妻书》的分析,本文将探讨其与现代离婚声明之间的联系,并进一步提出,无论是《放妻书》还是现代离婚声明,它们都是发布者塑造和维护自身"人设"的媒介工具。  相似文献   

Value for learning during this time of transformation: the first-year students’ perspective     

Shalini Dukhan 《高等教育研究与发展》2020,39(1):39-52

ABSTRACT

Formal education was used by the apartheid government to prepare black South Africans for manual labour, thus there was little curricular focus on the development of higher-order cognitive skills. With the abolition of apartheid in 1994, the education system was re-valued and re-evaluated to provide wider access to quality education; the focus of education policies moved towards the development of self-regulation and higher-order cognitive skills for all learners. There is now a generation of learners who have experienced their schooling in the transformed education system, and it would be useful to understand, from their perspective, what they value in their development of learning within the higher education space. This study answers the question ‘Post-apartheid, what learning methods and resources do first-years perceive to be valuable to their learning when they enter university?’ Participants included 344 students taking a Biology course provided to medical science students at a South African university in 2018. Two questionnaires were administered towards the end of a six-week lecture period, responses were evaluated quantitatively and qualitatively. The first survey, comprised of Likert-style questions, was conducted to determine the students’ views on the mechanisms which they used to support their learning. The second questionnaire comprised open-ended questions and focused on the students’ perception of their learning experience in the course. The findings show that there was a significant (p?<?.001) percentage of first-years who thought that rote-learning would suffice for examination preparation at university, and preferred to engage with their peers and the textbook before they engaged with their lecturers when navigating challenging concepts. Schwartz's model of social values is used to show that more needs to be done for the development of higher-order thinking and self-regulation when students enter university, and to mitigate alienation between students and staff.  相似文献
