鲁国君臣的书法——《春秋》书法探讨之一

《春秋》记鲁国君臣事,自有其法,与记他国事有明显不同。约合观之,有称谓有内外之别;记鲁事多有讳语;君臣聘会班次与用语多有讲究;征伐自败不书,他败则书等特点。     

在田径长距离比赛中采用计算机辅助裁判技术的研究

主要阐述了计算机辅助裁判 （简称 Ｃ Ａ Ｊ） 技术在田径比赛中尤其是在终点裁判工作中的重要作用和优越性。在田径长距离比赛中 （２０ ｋｍ 竞走和５０ ｋｍ 竞走项目）, 经常出现记错圈的现象, 采用这一技术可以辅助裁判员准确地完成工作。     

也谈“et al”应用之规范

通过对国内外186种科技期刊目次页和参考文献中"et al"编辑规范问题进行调查研究后发现,国内科技期刊"etal"的编排格式较之国外科技期刊更为混乱.针对该问题进行了分析,并对其规范化问题提出建议.     

从“对手”分析青年教师讲课比赛的策略

讲课比赛授课对象不仅是学生,重要的听众是评委。本文把评委当青年教师讲课比赛中的对手,只有征服对手才能赢得比赛。通过对＂对手＂的分析,归纳了比赛应从选讲内容、授课语言、PPT制作、授课节奏等方面努力来提高讲课效果。     

高保真录音回放攻击取证算法与仿真验证

针对语音认证系统中高保真录音回放攻击问题,开展了录音回放攻击取证的研究,论述了基于信道模式噪声和回放语音MFCC特征参数提取的取证算法;通过labview软件编程进行仿真验证,提取了疑似回放攻击语音和原始语音信道噪声差值频谱图和疑似回放语音MFCC特征值,结果表明通过提取回放语音中信道模式噪声和MFCC特征参数并设计滤波器去噪能够识别原始语音和高保真录音的差异,为语音司法鉴定和语音认证系统的设计提供了理论依据。     

影像记录的优势——纪录片在非物质文化遗产保护传承中的作用

近些年,在国家政策引导下,非物质文化遗产保护传承逐渐升温,各种方式的保护工作广泛开展。纪录片具有"视"与"听"的独特表现方式,使得其在非物质文化遗产的保护和传承方面具有其他手段无可比拟的优势。本文结合时代环境阐述了以纪录片形式保护非物质文化传承所达到的效果。     

Adventures in Flipping College Algebra

Abstract

This paper outlines the experience of a university professor who implemented flipped learning in two sections of college algebra courses for two semesters. It details how the courses were flipped, what technology was used, advantages, challenges, and results. It explains what students do outside of class, what they do inside class, and discusses what students thought of the course based on surveys and course evaluations. It also compares results on a similar final exam to those of a control group.

WebIntera-classroom: an interaction-aware virtual learning environment for augmenting learning interactions

Interaction is critical for successful teaching and learning in a virtual learning environment (VLE). This paper presents a web-based interaction-aware VLE – WebIntera-classroom – which aims to augment learning interactions by increasing the learner-to-content and learner-to-instructor interactions. We design a ubiquitous interactive interface that integrates a pen-and-paper interface with a web-based whiteboard to promote effective learner-to-content interactions. We develop a learning analytics tool that instantly shows learners’ learning interactions, with which instructors can supervise learner-to-instructor interactions. We implement a high-granularity Learning Analytics Engine (hgLAE) to broadcast, record and play a lecture recording. The hgLAE identifies hotspots in a lecture recording and raises students’ awareness of the hotspots when they watch the recording. WebIntera-classroom has been deployed in 11 universities in China. The system obtained high satisfaction in the questionnaires (N?=?464) and face-to-face interviews (N?=?60) conducted with the users from China Jiliang University. We compared the students’ performance, respectively, achieved in traditional classroom and in WebIntera-classroom at China Jiliang University during 2012–2013. The result demonstrates that the students could gain performance improvement by using WebIntera-classroom.
