统计学专业教学现状与改革的思考

统计学是是一门多学科相交叉的边缘学科,具有很强的应用性。本文通过对美国一流统计学专业教学特点与特色的描述,分析了国内统计学教学中存在的主要问题,最后从教学理念转变、课程计划更新、教材资料优选、应用能力培养四个方面对该专业的教学改革提出了自己的观点。     

关于独立学院统计学课程教学的几点思考

独立学院作为一种新兴的办学模式,主要以应用型人才为培养方向。统计学作为一门应用性极强的课程,在独立学院中广泛地开展。作者结合自身教学实践体会,对独立学院非统计专业的统计学课程教学中存在的问题,从教师队伍、教学过程、考核环节等方面进行分析,提出几点看法,以期促进独立学院统计学课程教学的改进和发展。     

心理统计学教学改革的思考与实践

文章结合心理统计学教学存在的问题和发展趋势,尝试进行心理统计学课程的教学改革探讨,具体包括教学内容、教学方法和评价方法3个方面：教学内容改革主要体现为从应用的角度对教学内容进行取舍;教学方法改革主要涉及在教学形式方面的探索;评价方法改革简述了在形成性评价方面的尝试。结果表明,教改在一定程度上改善了之前教学中存在的问题,提高了学生的相关能力,也促进了教师的发展。     

Unders and Overs: Using a Dice Game to Illustrate Basic Probability Concepts

In this paper, the dice game Unders and Overs is described and presented as an active learning exercise to introduce basic probability concepts. The implementation of the exercise is outlined and the resulting presentation of various probability concepts are described.     

Online homework impact in undergraduate mathematics and business statistics courses

This evaluation examines the impact on student success rates related to changes in instructional programmes in undergraduate mathematics and statistics courses. Success for students taking courses with a computer-based homework component was compared with success of students who took the course in prior semesters without the computer-based component. Graphical and analytical tools are used to compare results. Results come from multiple semesters of each type of homework application, for both pre-calculus algebra and business statistics courses. Students whose performance is utilised in this study are undergraduate students taking introductory level college mathematics or business statistics courses, with mostly no prior instruction at this level. Comparing the success of the intervention group with the success of the baseline control group, findings support that the students using the computer-based homework instruction are just as successful as those using the traditional method of homework instruction. Utilising the online homework applications, provide several important advantages in today’s universities, including the reduced time for faculty grading, consistency of graded assignments across all sections of a course and most importantly, immediate feedback for students.     

Four Perspectives on Flipping the Statistics Classroom: Changing Pedagogy to Enhance Student-Centered Learning

Abstract

The term “flipped” or “inverted” classroom includes a broad range of pedagogical innovations, and has recently received a significant amount of press. Although flipping an entire course might be a more extreme step than most are able to take, we discuss modular ideas for change that can be more easily implemented. This paper offers the perspective of four faculty members at different institutions who have all flipped material in statistics courses that were already highly interactive and activity-based. We share common pitfalls and core ideas that were found among diverse environments.

中国省域碳强度集群的空间统计分析

论文使用空间统计分析中的全局Moran’s I、局域Moran’s I等指数对2001-2012年间我国碳强度的空间自相关性以及集群情况进行分析,发现全国省域碳强度的空间自相关性为正,东部地区内部省域的碳强度空间自相关现象非常明显,西部地区相对不明显,中部最弱。西部地区省份的碳强度多为高-高聚集,以甘肃、陕西、内蒙古3个地区为代表,东部地区多为低-低聚集,以浙江、福建、广东、江西4个地区为代表。论文还进一步结合资源禀赋、能源供需分布、产业结构和收入水平等对上述地区碳强度聚集的原因进行了分析,提出针对性的政策建议。     

方差分析中F统计量计算教学研究

以具体工作中方差分析的两个例子,尝试回答方差教学中经常碰到的两个问题,(1)方差分析能解决什么问题;(2)怎样解释方差分析中F统计量的计算。通过教学过程两种讲授方法的比较,得出从样本数据分布的视角进行F统计量计算的教学方法效果更好。     

时间偏好影响下的海洋牧场蓝碳生态产品价值实现机制

海洋牧场是促进海洋渔业转型升级和海洋生态文明建设的重要举措,其蓝碳生态产品价值实现机制则是将“绿水青山”转化为“金山银山”的关键环节。然而,参与主体单一、生态价值回报不足、跨期价值转换偏差等问题,严重制约着中国海洋牧场蓝碳生态产品价值实现机制的市场化、可持续运作。鉴于此,本文在“政府激励+蓝碳交易”直接机制的基础上融入“蓝碳质押信贷”间接机制,设计了一个涵盖政府、渔企、第三方服务机构（碳交易中心、银行等）3个主体,现期收益与未来收益可转换的海洋牧场蓝碳生态产品价值实现机制,同时将时间偏好引入演化博弈模型,分析了渔企时间偏好对该机制运作的影响。研究结论如下：①渔企时间偏好对海洋牧场蓝碳生态产品价值实现机制存在影响,对3个主体策略行为的影响而言,对渔企影响最大,其次是第三方服务机构、政府。②在直接实现机制中,补贴金额和环境保护税越高,越有利于推动海洋牧场及其蓝碳生态产品市场发展;且相较于补贴,环境保护税这一负激励的推动作用更强。蓝碳现货价格越高,渔企采取海洋牧场模式的意愿越高,但对第三方服务机构开展蓝碳质押信贷业务的意愿产生倒“V”型影响,即先促进后抑制。③在间接实现机制中,信贷风险越低,质押率越高,就越有利于推动海洋牧场及其蓝碳生态产品市场的有序发展;而守信奖励、违约金等信贷奖惩措施应适中,过高或过低均不利于实现海洋牧场及其蓝碳生态产品市场的良性发展。以上结论对完善中国海洋牧场蓝碳生态产品价值实现机制提供了重要的科学依据。
