高职文秘专业考试制度初探

进行以"实践能力测试"为核心的考试制度改革就是要摒弃以往传统的考试制度,侧重对学生的实践能力考察,并引导学生重视知识运用能力、分析和解决问题能力、自我评价和评价他人能力及心理素质、协作精神、职业道德等。这种理念主要是培养出适应现代需要的,具有更强实践能力、创新能力和创业精神的现代化文秘人才。     

微信红包随机金额生成算法模拟及应用

构造了微信红包随机金额的模拟算法,并验证了模拟算法的有效性。通过模拟算法,产生了大量微信红包随机金额数据,分析这些数据表明:(1)微信红包随机金额呈正态分布,是在红包份数较少的情况下,表现出的一种巧合,在红包份数较多的情况下,随机金额并不符合正态分布;(2)对一个微信随机红包,概率上,每个人抢到的红包金额是相等的,即抢红包的先后次序对抢到金额的多寡没有影响;(3)对一个微信随机红包,越晚产生的随机金额,其波动范围越大,即先抢红包的人,抢到平均金额的可能性比较高,后抢的人,要么抢到较小的金额,要么抢到较大的金额。     

基本建设单位工程预付款业务处理的分析与思考

作为一个基本建设单位，在开展工程建设过程中，经常会发生预付工程款业务。本文通过对该类业务核算常用的两种会计处理方法的分析，指出这两种方法各自存在的不足及其对基建报表数据编报的影响。并在上述方法的基础上提出了一些处理问题的新设想，以期提供较真实、完整的财务资料和财务信息。     

浅析复杂材料的提取练习效应

提取练习效应具体指学习某一内容后,进行测试比再次学习的记忆保持效果更好,即使测试后没有反馈也依然存在。研究发现对词语、篇章及技能等类型的学习都存在提取练习效应。但近年来一些研究发现复杂材料不存在提取练习效应。本文综述了有关复杂材料不存在提取练习效应的实验,并讨论了复杂材料没有出现提取练习效应的内部原因。     

Enhanced teaching and student learning through a simulator-based course in chemical unit operations design

This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.

论建设单位在工程实施阶段的造价管理

在工程实施阶段,虽然节约投资、降低造价的空间不大,但浪费投资、增加造价却有极大的可能性,因此,在此阶段必须组织工程招标,加强工程合同管理,强化施工过程管理,严格控制工程变更,提升工程结算水平,从而切实有效控制该阶段的工程造价,以确保建设单位的投资效果。     

Learning styles in engineering education: the quest to improve didactic practices

This article discusses a dilemma that engineering educators encounter when attempting to develop pedagogical methods: that of finding efficient and scientifically valid didactic practices. The multitude of methods offered by educational consultants is perplexing. Moreover, the popularity of commercially offered solutions such as learning styles testing makes them appear attractive. The study presents one case of application of learning styles, the consequent problems and evaluation of results. It concludes that the use of learning styles is not supported by current pedagogical theories. Practices to foster interdisciplinary understanding between learning sciences and engineering are proposed in order to improve engineering education, most notably collaborative projects between university departments.
