Neuroanatomy education is a challenging field which could benefit from modern innovations, such as augmented reality (AR) applications. This study investigates the differences on test scores, cognitive load, and motivation after neuroanatomy learning using AR applications or using cross-sections of the brain. Prior to two practical assignments, a pretest (extended matching questions, double-choice questions and a test on cross-sectional anatomy) and a mental rotation test (MRT) were completed. Sex and MRT scores were used to stratify students over the two groups. The two practical assignments were designed to study (1) general brain anatomy and (2) subcortical structures. Subsequently, participants completed a posttest similar to the pretest and a motivational questionnaire. Finally, a focus group interview was conducted to appraise participants’ perceptions. Medical and biomedical students (n = 31); 19 males (61.3%) and 12 females (38.7%), mean age 19.2 ± 1.7 years participated in this experiment. Students who worked with cross-sections (n = 16) showed significantly more improvement on test scores than students who worked with GreyMapp-AR (P = 0.035) (n = 15). Further analysis showed that this difference was primarily caused by significant improvement on the cross-sectional questions. Students in the cross-section group, moreover, experienced a significantly higher germane (P = 0.009) and extraneous cognitive load (P = 0.016) than students in the GreyMapp-AR group. No significant differences were found in motivational scores. To conclude, this study suggests that AR applications can play a role in future anatomy education as an add-on educational tool, especially in learning three-dimensional relations of anatomical structures. 相似文献

新课改以来,由于对课改理念的僵硬化解读,学校精细化管理制度带来的压抑与控制,以及盲目模仿带来的伤根性移植,师生教学行为出现了异化现象:教学资源开发异化为材料的堆砌,教学方法选择异化为学生盲目的探究,教学环境营造异化为缺乏深度思维的"热热闹闹",教学评价异化为盲目赞扬。对课改理念进行个性化解读,学校积极营造创造性教学氛围,以及唤醒师生主体意识是教学异化行为矫正的重要路径。 相似文献

中文电子病历的分词及实体识别研究 总被引:1,自引:0,他引:1
[目的/意义]健康医疗大数据是我国重要的基础性战略资源,本研究对中文电子病历分词与实体识别的探讨与实证较好地完成了医疗数据的信息抽取任务,对今后医疗大数据在语义层面的应用发展具有重要意义。[方法/过程]本研究首先融合权威词表、官方标准、健康网站数据及其他医学补充词库构建了词语数量级达到10万的医学词表;然后对电子病历的字段进行分词,对比了jieba工具、导入词典后的jieba、无监督学习及AC自动机4种模型的分词效果;最后,以自动分词和人工标注结果为语料,实现基于条件随机场的电子病历实体识别研究,并比较不同实体类别以及不同文本特征下的实体识别效果,选出最优模板。[结果/结论]分词结果显示,AC自动机的效果最好,F值可达82%;实体识别结果表明,"检查"和"疾病"实体的识别效果最好,而"症状"的识别效果不太理想。 相似文献

Virtual microscopy (VM) is a widely used teaching method in Medical Education in many developed countries. In Brazil, however, this is not the case for most medical schools, considering Brazilian social inequality and uneven access to technology. Recently, the Covid-19 pandemic has also challenged Universities to seek and make a transition toward more effective methods of full-time online education. Thus, the main goal of this work was to verify student's perception and academic performance, assessed upon VM implementation in a Brazilian Medical School. Ribeirao Preto Medical School students answered a 26-question survey with regards to optical microscopy (OM) and VM. Academic performance was compared between participants that were (year of 2019) or were not (year of 2015) exposed to VM. Taken the results together, subjective impressions such as handling, suitability, learning effectiveness, and pleasure using the tools, have shown a higher score for virtual microscopy (median = 29), when compared to optical microscopy (median = 24) with a P-value < 0.001 by Wilcoxon rank test, upon measurement using an ordinal scale. Regarding academic performance, no statistically significant differences were found between groups (P-value = 0.38, Cohen's d = 0.19). Therefore, VM proved to be adequate to the Brazilian medical education in light of Brazilian social contexts and Covid-19 pandemic. 相似文献

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy. 相似文献

重理论思辨、轻实践研究,研究方法简单粗糙,是当前课程与教学论主流研究范式的两大缺陷。欠缺科学精神、方法意识薄弱、评价机制不健全,是造成当前主流研究范式缺陷的主要原因。基于此,应从六个方面改善课程与教学论主流研究范式:关注对实践问题的微观研究和行动研究;加强方法意识,融入科学精神;建立课程与教学论的方法论体系;转变研究思维方式;改善现有评价体系;加强研究生培养过程中方法意识的培养和方法训练。 相似文献

对于什么样的"课"是"好课",历来有多种说法,可谓仁者见仁,智者见智。然而,这些所谓"好课标准"都是成人所构建的。课堂生活是孩子们经历最多、体验最深的一种生活方式。教育现象学研究要求关注教育情境中师生的"生活体验(世界)",关注教育的实际发生领域,关注生活的意义。由此,本研究旨在用教育现象学的方式倾听孩子们内心的声音,用描述性的语言勾勒出孩子们心目中的"好课堂"。 相似文献

This article takes as its focus Lefebvre's trialectic of conceived, perceived and lived spaces as a lens through which to scrutinise the 2013 English Literature Curriculum, and to explore the extent to which creative spaces might exist within that curriculum. The article analyses how the curriculum is envisaged by policymakers and how it might be expected to be translated into practice, utilising the wording of the policy document to facilitate an exploration of what its underlying intentions might be. The author's experience of teaching a poem from the new curriculum is used in order to provide illustrative examples of the ways in which teachers’ and learners’ experiences of the curriculum might, in practice, diverge from the direction envisaged by policymakers as teachers negotiate creative spaces within their classrooms. 相似文献

本文从建构主义课程观的视角,分析了目前藏族教育中藏汉双语课程所存在的不足,并就构筑建构主义的藏汉双语课程阐述了自己的观点,认为藏族学生是建构藏汉双语课程的主体者;双语教师是学生主动建构意义的帮助者、促进者;社群中的相关人士在藏汉双语课程中起着不可低估的"话语"作用。在藏汉双语课程的教学中应努力发挥以上三方面作用,并使之形成合力,探索出一条行之有效的教学模式。 相似文献
