Shortly after the election of the new Western Australia (WA) Government in March 2017, the new Premier, Mark McGowan, announced the first round of Machinery of Government changes to the WA public sector. The structural changes were promoted as creating collaborative departments focused on whole-of-government objectives and for delivering services in a more efficient and effective way. Part of these changes was to move the State Records Office of Western Australia under the State Library of Western Australia. The Australian Society of Archivists Western Australia Branch Committee discusses this act and the implications for the independence of the State Records Office. 相似文献

结合计算机绘图的特点改进《机械制图》教学 总被引:1,自引:0,他引:1

目前,传统的机械制图教学模式与现代计算机绘图技术新要求的种种接轨问题、融合问题日益凸显出来,《机械制图》教学模式一味地固守老的传统模式,势必会造成学生掌握计算机绘图技术的不适应,也很容易导致学生在《机械制图》学习过程中走弯路。本文提出《机械制图》教学应结合计算机绘图的特点进行改进。 相似文献

Since their inception, a dominant characteristic of higher education institutions has been their reliance on the advantages conferred by geographic and political boundaries. However, emerging technologies and growing consumer power are challenging the status quo. The application of Internet-based information and communication technologies in education—e-learning—is now making it possible for education to transcend space, time, and political boundaries. In e-learning, content and mode of delivery are increasingly defined by external groups: students as well as employers. The emergence of e-learning is weakening the dominance of traditional providers of higher and continuing education—nonprofit colleges and universities—and they are being challenged by a proliferation of alternative institutions and providers with the skills and attitudes required to succeed in the new educational marketplace. Partnerships will allow traditional suppliers and intermediaries to contribute from their respective comparative advantages. In a common emerging model, traditional universities provide the intellectual capital, content, and content support; evaluate student performance; and award appropriate degree credit or certification. Intermediaries contribute in such areas as hardware and software provision, instructional design for the Web, website and communication for maintenance, record keeping, teacher training, and technical support for courseware development and marketing. Although this trend is not yet well advanced in the Asia Pacific Region, there are already a few pioneers, and interest is strong and growing among the major stakeholder groups—traditional academic institutions, traditional students, emerging intermediaries, professionals with a need for continuing education, and private sector corporations with the need to provide educational opportunities for their workforce. The Asia Pacific Regional Technology Centre (APRTC) is an example of an emerging intermediary organization. Its primary focus is on providing continuing educational opportunities for agricultural professionals throughout the Asia Pacific. It relies almost exclusively on e-learning for educational delivery and carries out its work through multisectoral partnerships. Initial experience indicates that the approach works in the region and is cost effective and that all partners and the clients can and do benefit from the collaboration. 相似文献

Studying political economics could improve the students' ideological standards and professional qualifications, so we must insist on and strengthen teaching and study of political economics. The unscientific orientation, lacking of the high-level textbook and lagging behind practice are the main reasons, which cause the difficulties in the teaching of political economics. In order to solve the existing problem we must re-recognize the theoretical system of political economics, deepen the goal and direction of the teaching reform of political economics, and deepen the practice of the teaching reform of political economics. 相似文献
