Enhancement of Anatomical Education Using Augmented Reality: An Empirical Study of Body Painting

Students in undergraduate premedical anatomy courses may experience suboptimal and superficial learning experiences due to large class sizes, passive lecture styles, and difficult-to-master concepts. This study introduces an innovative, hands-on activity for human musculoskeletal system education with the aim of improving students’ level of engagement and knowledge retention. In this study, a collaborative learning intervention using the REFLECT (augmented reality for learning clinical anatomy) system is presented. The system uses the augmented reality magic mirror paradigm to superimpose anatomical visualizations over the user’s body in a large display, creating the impression that she sees the relevant anatomic illustrations inside her own body. The efficacy of this proposed system was evaluated in a large-scale controlled study, using a team-based muscle painting activity among undergraduate premedical students (n = 288) at the Johns Hopkins University. The baseline knowledge and post-intervention knowledge of the students were measured before and after the painting activity according to their assigned groups in the study. The results from knowledge tests and additional collected data demonstrate that the proposed interactive system enhanced learning of the musculoskeletal system with improved knowledge retention (F_(10,133) = 3.14, P < 0.001), increased time on task (F_(1,275) = 5.70, P < 0.01), and a high level of engagement (F_(9,273) = 8.28, P < 0.0001). The proposed REFLECT system will be of benefit as a complementary anatomy learning tool for students.     

论向子諲的《酒边词》

向子諲的《酒边词》含《江南新词》与《江北旧词》。前者收南渡以后之作,较深刻地反映了现实,以诗为词,多旷放之作,艺术表现上较有生气。后者收南渡以前之词作,内容多写闺情、恋情,艺术上承继欧、晏词风,本色当行,受到选家的重视,然欠创新锋芒。

论量刑程序分立

量刑规范化改革的一个重要方面是程序改革。现行刑事诉讼制度中量刑方面存在多种缺陷,这些缺陷和问题的产生,很大程度上是由于刑事诉讼程序所采用的定罪量刑合一的模式。刑事诉讼制度的体系化特性,决定了量刑改革不可能仅仅依靠程序上的分离,而是需要从整体上对刑事诉讼制度进行调整。在现有体制内进行修正,或将定罪量刑分而治之,是两种不同的改革方案。通过对两种模式的可行性和必要性分析,可以得出结论,将定罪与量刑在程序上分而治之是最佳方案。     

略论刘知几的审读观

人的认识是有局限的,对圣贤、名著既不能全盘肯定,也不能全盘否定,恰当的原则是＂爱而知其丑,憎而知其善＂;一部优秀的书稿,体例要严整,名称与内容要相符。这两点是刘知几审读的重要观点。这种观点对我们今天审读书稿仍有重要的借鉴意义。

Adding immersive virtual reality to a science lab simulation causes more presence but less learning

Virtual reality (VR) is predicted to create a paradigm shift in education and training, but there is little empirical evidence of its educational value. The main objectives of this study were to determine the consequences of adding immersive VR to virtual learning simulations, and to investigate whether the principles of multimedia learning generalize to immersive VR. Furthermore, electroencephalogram (EEG) was used to obtain a direct measure of cognitive processing during learning. A sample of 52 university students participated in a 2 × 2 experimental cross-panel design wherein students learned from a science simulation via a desktop display (PC) or a head-mounted display (VR); and the simulations contained on-screen text or on-screen text with narration. Across both text versions, students reported being more present in the VR condition (d = 1.30); but they learned less (d = 0.80), and had significantly higher cognitive load based on the EEG measure (d = 0.59). In spite of its motivating properties (as reflected in presence ratings), learning science in VR may overload and distract the learner (as reflected in EEG measures of cognitive load), resulting in less opportunity to build learning outcomes (as reflected in poorer learning outcome test performance).     

拟古写真交融奇辞奥旨同辉——韩愈《琴操十首》的审美观照

韩愈的<琴操十首>是我国历代琴操诗的扛鼎之作.它借古鏊今,笞挞现实社会中的佞人专权,表达诗人憧憬圣贤的诉求;它巧妙地化用本事抒怀,展现了诗人的忠君意识、遗弃意识、反省意识和自赎意识相互交织的独特心灵世界;它奇辞与奥旨同辉,生命与意象叠印,以无我凸显自我,从而做到了古今贯通,物我无间,使音乐与诗歌完美地结合在一起,极大地推动了我国音乐文学的发展.
