对大学实验教学若干问题的厘析(续)

实验教学改革是新一轮高等教育质量工程中教学改革的重点和热点。本文上一部分从厘析大学实验教学的目的和原则出发,对当前实验教学改革中出现的一些新概念、新名词进行剖析,以弄清楚各类教学实验的内涵与功能。这一部分着重讨论各类实验的实施及需注意的问题,为进一步深化实验教学改革提供有益的参考与指导。     

庐山植物区系的特征和植被的分布

本文通过对庐山植物区系成分的分析，指出庐山植物区系特征是：以亚热带植物成分为主，还有热带和温带植物成分的亚热带低山植被，具有古热带和冷北极两大植物区系成分的相互渗透、相互交融的一种过渡性自然景观．在植被分布上，明显地反映出亚热带低山植被的垂直地带性分布规律．     

大厦与电气接地

通过对几种低压配电接地型式的比较、分析,提出适合大厦的低压配电系统的接地型式及建筑物的共用接地装置和等电位连接的措施与设计方法。     

投射与语体分析

本主要讨论小句复合体中投射现象与英语语体的关系。投射是指小句间一种逻辑语义关系。而语体是指语言在具体语境中的实现形式，是指语言的功能变体。投射在语篇中的出现并非偶然，而是与一定的语体相联系。不同的英语功能变体呈现出不同数量的投射句。因此，投射结构的选择受到语体类型的制约，同进，投射小句的数量或出现频率也呈现一定的语篇类型。

在线网络文学批评类型探析

批评文章首发于网页上是在线批评区别于非在线批评的一大标志。由于在线匿名特性和无编辑把关带来的自由和在线即时评论,在线网络批评以俏皮、调侃、幽默的话语点评,啸聚网民,营造出旺盛的人气,其所具有直觉性、特指性、明晰性、生活化、短小犀利、批评客体边缘化等特征,推动了网络写作的兴旺和网络原创文学的发展。     

The skeletons in our closet: E‐learning tools and what happens when one side does not fit all

In the anatomical sciences, e‐learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual‐kinesthetic learning modalities are scarce. The study examined how a visual‐kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two‐dimensional (2D) e‐learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual‐task study to: (1) investigate if a dual‐task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them. Students were assessed using knowledge scores, Stroop task reaction times, and mental rotation test scores. Results demonstrated that the dual‐task paradigm was not an effective tool for measuring cognitive load across different learning modalities with respect to kinesthetic learning. However, our study highlighted that handing physical specimens yielded major, positive impacts on performance that a simple commercial e‐learning tool failed to deliver (P < 0.001). Furthermore, students with low spatial ability were significantly disadvantaged when they studied the bony joint and were tested on contralateral images (P = 0.046, R = 0.326). This suggests that, despite limbs being mirror images, students should be taught the anatomy of, as well as procedures on, both sides of the human body, enhancing the ability of all students, regardless of spatial ability, to take anatomical knowledge into the clinic and perform successfully.
