大学数学基础课程三位一体教学范式以建构主义的意义协商、抛锚教学、算法图式和随机进入等四个核心理论为基础.教学范式中,真实的问题情境,激发学生学习的兴趣;精心的教学设计,符合学习心理的规律;丰富的教学形式,提供有效的技术支持;多维的教学目标,提高学生的综合素质.经过十年教学改革研究和实践检验,该教学范式取得明显成效.

利用经验贝叶斯方法研究了在线性损失下指数-威布尔分布参数的经验Bayes检验问题,构造了在历史样本是长程相协样本下的参数经验Bayes检验函数,并证明了所提出的经验Bayes检验函数满足渐近最优(a.o.)性及给出了该函数的收敛速度.

新时代,教育当有新作为.新时代话语的动态性、多样性、即时性和虚实两相性特征为新时期辅导员话语体系的重塑提供了契机,也带来了巨大的挑战.在新时代的复杂语境中,辅导员话语体系面临着四种困境,即情感性话语对宣传式话语的消解、平等式话语对权威式话语的消解、大众式话语对精英式话语的消解以及互动式话语对控制式话语的消解.针对辅导员话语体系的困境,需要通过话语体系的理念创新为辅导员话语体系的重塑提供前提条件;通过内容创新把握辅导员话语体系重塑的核心要求;通过载体重组为辅导员话语体系重塑提供平台保证;通过机制完善为辅导员话语体系重塑提供根本的保障,从而有效提升新时代辅导员话语体系的育人实效性.

在几何中,由一族直线运动所产生的曲面叫做直纹面,这些运动的直线称为直母线.双曲抛物面就是典型的直纹面,并且它有两族直母线.本文通过对双曲抛物面的直纹性进行研究,探索了双曲抛物面在建筑、电力工程、日常生活、宇宙学中的应用,并进一步研究了手工制作双曲抛物面的方法.

教师观的演变可以反映出不同时代教育状况的变更.本文以比较的视野,对传统社会、近代工业社会及后现代视野下教师观中的教师地位、教师作用及师生关系作了比较分析.在此基础上,对当前社会背景下树立新型的教师观作出了相关论述.

在终身教育的时代背景下,高校工会作为高校教职工之家,要努力发展成为学习型工会,与时俱进,不断创新.为适应时代的需求和高校的发展,高校学习型工会建设应注重与教职员工培养相结合、与工会文化建设相结合、与工会信息化建设相结合,以此提升其工作的实效性.

As one of the important public compulsory courses in colleges and universities, advanced mathematics is now facing many problems in actual teaching, such as unsmooth transition and convergence in knowledge, monotonous and boring lectures of theory, weak practicability in teaching efficiency, a lack of deepening and expansion in teaching contents, single teaching methods, etc. All these problems make the teaching efficiency of advanced mathematics not so good. Therefore, teachers are sup-posed to optimize the teaching of advanced mathematics by strengthening the transition and convergence between advanced mathematics and high school knowledge, the integration of ad-vanced mathematics and history of mathematics, and developing the integration of advanced mathematics with the major features and actual application, the convergence between advanced math-ematics and mathematical knowledge for the postgraduate exami-nation, and enhancing the integration of advanced mathematics teaching and multimedia teaching techniques.

In order to reach the target of maximizing overall value on supply,this article studies and explores economic order quantity and cost from multiple aspects.It formulates the mathematical models in different conditions,finds out solution or methods,which is something like solution,analyses the sensitivity of economic order quantity.Through the analysis on practical problems,it further shows the advantages and disadvantages of different purehasing ways and points out the effective methods of supply chain at the stage of purehase and storage.

The paper presents the conception and the circulate mode of the recycle economy-supply china management, the purchase is studied under it. In order to reduce the economic and environment cost of the supply chain, there are two ways on the purchase, one is to select the recycle materials which is in favor of the environment protection; the other is to adopt the united purchase which can reduce the cost of purchase.
