在新课程改革的浪潮冲击下，教育观念、教学方式、教学行为有了新的诠释。在这种情况下，教师也应该转变自身的角色。文章主要从教师成为学生学习的促进者、成为平等合作者、成为终身学习者、成为教育研究者这四个方面对教师角色的转变进行论述。 Under the impact of the new curriculum reform, the educationalconcept, teaching method and teaching behavior have a new interpretation. Inthis case, teachers should also change their role. This article mainly discusses thetransformation of teachers’ roles from four aspects: teachers become facilitatorsof students’ learning, equal collaborators, lifelong learners and educationalresearchers.

本文探讨了对于数学基础相对薄弱的商科类学生统计学教学的特点和方法。商科类学生面临运用数理统计方法解决经济、管理中的实际问题，但是统计学要求有一定的数学基础、数学思维方法，这对于商科类学生来说是一个挑战。本文试图说明如何在教学中运用适当的方法让学生掌握统计学思想、理论和运算方法。 This paper discusses the characteristics and methods of Statistics Teaching for business students whose mathematical foundation is relatively weak. Business students are faced with using mathematical statistics to solve practical problems in economy and management, but statistics requires certain mathematical basis and mathematical thinking method, which is a challenge for business students. This paper attempts to explain how to use appropriate methods in teaching so that students can master statistical thinking, theory and calculation methods.

统计学具有高度的客观性和系统性，是一门实践性和应用性都很强的 综合性学科。要让学生掌握统计学知识，把统计学方法和思维运用于实际，最 好的方法之一就是实行情景模拟教学，使学生在有限的时间内接触实践活动的 真实模拟，提高学生解决实际问题的能力。 Statistics has a high degree of objectivity and systematicness, and it is a comprehensive subject with strong practicality and application. In order to let students master the knowledge of statistics and apply the statistical methods and thinking to practice, one of the best methods is to carry out situational simulation teaching, so that students can contact the real simulation of practical activities in a limited time and improve their ability to solve practical problems.

在认真研究电源网格结构的基础上，介绍了一种电压降分析的新方法。 这种基于概率统计的方法能够快速简便的估计出电压降的概率分布情况。这种 利用概率统计分析电压降的方法在一些电源网格（包括一些工业处理器）中得 到了较为理想的结果。 With a thorough research on the structure of power grid, we put forward a new kind of approach to the IR drop problem. This approach is based on probability and statistics, which can give us an outlook of the probability distribution of IR drop. The analysis was carried out on a number of grids, including the power grids of industrial processors and we can see that this approach is very effective.

决策是管理学中很重要的内容。本文以决策前的市场预测、决策中方 案的选择、决策后方案评估和反馈这三个方面为背景，阐述了统计学技术在管理决策中的应用，同时指出其缺点，并说明 了统计技术是管理学自身得以完善的有益工具。 Decision making is a very important content in management. In this paper, based on the three aspects of market prediction before decision-making, scheme selection in decision-making, scheme evaluation after decision-making and feedback, the application of statistical technology in management decision-making is described, its shortcomings are pointed out, and it is shown that statistical technology is a useful tool for management to improve itself.
