Exploring perceptions and attitudes towards teaching and learning manual technical drawing in a digital age

This paper examines the place of manual technical drawing in the 21st century by discussing the perceived value and relevance of teaching school students how to draw using traditional instruments, in a world of computer aided drafting (CAD). Views were obtained through an e-survey, questionnaires and structured interviews. The sample groups represent professional CAD users (e.g., engineers, architects); university lecturers; Technology Education teachers and student teachers; and school students taking Scottish Qualification Authority (SQA) Graphic Communication courses. An analysis of these personal views and attitudes indicates some common values between the various groups canvassed of what instruction in traditional manual technical drafting contributes towards learning. Themes emerge such as problem solving, visualisation, accuracy, co-ordination, use of standard conventions, personal discipline and artistry. In contrast to the assumptions of Prensky’s thesis [(2001a) Digital natives, digital immigrants. On the Horizon 9, 5. NCB University Press Retrieved Oct 2006 from http://www.marcprensky.com/writing/Prensky%20-%20Digital%20Natives,%20Digital%20Immigrants%20-%20Part1.pdf; (2001b) Digital natives digital immigrants, Part 2: Do they really think differently? On the Horizon 9, 6. NCB University Press retrieved Oct 2006 from http://www.marcprensky.com/writing/Prensky%20%20Digital%20Natives,%20Digital%20Immigrants%20-%20Part2.pdf] of digital natives, the study reported in this paper indicates that the school students apparently appreciate the experience of traditional drafting. In conclusion, the paper illustrates the perceived value of such learning in terms of transferable skills, personal achievement and enjoyment.     

基于 Tweedie 类分布的广义可加模型在车险费率厘定中的应用

分析广义线性模型和广义可加模型的理论基础和特点,从Tweedie类分布的独特视角归纳保险索赔额数据的分布规律。基于此建立了GLM—Tweedie和GAM—Tweedie索赔额拟合模型,以一组汽车保险损失数据为样本进行车险费率厘定和索赔额拟合的实证分析,识别“车、人、地”不同因素对费率不同的影响程度,助推我国车险费率厘定市场化改革精算技术的提升。     

浅谈AUTO CAD新技术在矿山测量中的应用

在20世纪80年代之前,矿山测量工作一直沿用传统的手工计算和绘图方法。而在80年代之后,随着计算机的应用和发展,AutoCad制图软件的普遍使用,矿山测量应用ActiveX Automation技术对AutoCad进行了结合矿山测量应用的编程语言二次开发,集成矿山测量CAD辅助绘图系统,从而解决了矿山测量数字化的问题。
