浅谈新课程标准下数学课堂教学的优化

新课标重在培养学生的自学能力、动手能力及实践探索能力,对教师的教和学生的学都提出了新的要求。为了较好的贯彻新课标的要求,要在课堂教学中下功夫,进行课堂教学优化设计。文章结合具体的教学经验,提出了数学课堂进行教学优化设计的具体方法和措施,以及提高学生主动性和创新性的方法。     

由《多面体欧拉定理》教学案例试探数学史的教育价值

数学文化不仅指数学知识,还指数学精神、数学思维方法、研究方法等,数学所具有的独特文化内涵,对学生的思想,道德和观念的发生、发展有着重大的影响,本文从《多面体欧拉定理》这节课出发探讨了数学史的教育价值:纯真自然的教育价值,思想方法的教育价值,积极的情感教育价值。     

Anxiety disorders,major depressive disorder and the dynamic relationship between these conditions: treatment patterns and cost analysis

Abstract

Objective: To determine the treatment pattern and impact on healthcare costs of anxiety disorders and major depressive disorder (MDD), and influence of their concomitance and subsequence.

Methods: A retrospective cohort study was conducted using a US reimbursement claims database. Adult patients with an incident diagnosis of anxiety or MDD (index date) were included. Their sociodemographic data, diagnoses, healthcare resource use and associated costs were collected over the 6 months preceding and 12 months following index date.

Results: A total of 599,624 patients were identified and included. Patients with phobia or post-traumatic stress disorder had the highest 12-month costs ($8,442 and $8,383, respectively). Patients with social anxiety disorder had the lowest costs ($3,772); generalized anxiety disorder ($6,472) incurred costs similar to MDD ($7,170). Costs were substantially increased with emergence of anxiety during follow-up in MDD patients ($10,031) or emergence of MDD in anxiety patients ($9,387). This was not observed in patients with both anxiety and MDD at index date ($6,148).

Conclusion: This study confirms the high burden of costs of anxiety, which were within the same range as MDD. Interestingly, the emergence of anxiety or MDD in the year following a first diagnosis of MDD or anxiety, respectively, increased costs substantially. Major limitations were short follow-up and lack of absenteeism costs.     

数学建模融入课程教学的探讨

数学类主干课程是工科院校中的重要基础理论课,随着高等教育日益趋向大众化,课程的课堂教学出现了前所未有的问题与挑战,教学改革势在必行。在重新审视大学主干数学类课程的特点和教学任务的基础上,对数学建模思想融入课程教学、数学建模内容融入课程的方式和嵌入点等进行了讨论,并提出了一些相应的教改设想。     

A Course in Economic Forecasting: Rationale and Content

This note shows that the impact of an increase in product price on factor demand in the typical textbook depiction is overstated to the point of indicating that competitive firms demand factors even when marginal product is negative.     

常用预测方法的模糊综合评判模型

高职楼宇智能化专业毕业综合实践环节的教学改革尝试

楼宇自动化（BA）系统课程实训的核心任务是以实验室里的中央空调模拟系统为对象进行BA监控系统的设计，并撰写设计报告。原有实训的内容设计比较枯燥乏味，与毕业后所从事的实际工作环境脱节，学生缺乏竞争压力，创造力难以发挥体现。因此，引入工程招投标机制，模拟竟标环境，让学生充分调动所学知识，亲历竞争场景，从而得到锻炼和提高，这是楼宇智能化专业毕业综合实践改革的有益尝试。     

工程图样中的模糊表达方法浅见

本文针对工程图表达过程中存在的一些"模糊"现象,提出模糊的图示方法,认为"模糊"表达不但可行,而且是图学表达领域的一块活跃领地.     

模糊数学在标准评估中的应用

简述了如何将模糊数学方法应用于对标准进行综合评估的过程;分析了各种类型标准及处在各阶段的标准所具有的特点,提出应选择的评判因素,并结合实例叙述了标准评估的步骤。使用此方法可将各方专家的模糊评价语言进行数学处理,实现了对标准的多方面、多层次的综合定量评估。
