实效性是数学课堂的生命——毫米、分米的认识教学例谈

课堂教学是一种目的性和意识性很强的活动,通过教学要使学生掌握知识,习得技能,发展智力,形成态度和相应的品质.学生学到什么?得到什么?这是任何教学改革都必须首先追问和考虑的问题.课程改革进行到今天,人们更加关注课堂实效性研究.从某种意义上说,实效性是课堂教学的生命.那么怎样提高小学数学课堂教学的实效性呢?笔者以人教版三年级上册第一单元第一课时毫米、分米的认识教学为例谈几点看法.     

数学作业的新尝试

数学课程标准非常关注学生在情感、态度、价值观和一般能力等方面的全面发展.笔者认为有必要改革教师出题,学生做习题的作业老形式,初步尝试了"数学周记"这种新做法.     

创新生物数学教学模式

本文根据医学院校教学教育特点和多年来本教研室教改经营，从理论与实践结合上提出了医学生数学素质培养的教学新模式刍形，并从构建优化课程结构体系，建立合理的教学运行机制，课程内容设置，教学实施策略等方面剖析了模式的内涵要素，对深化发展生物数学的教学改革进行了思考与探索。     

暮年而无暮气

我认定老年是天赐之福。前几天有个年轻人问我：老了有什么感觉。我吃了一惊,我还没想到我老了哩!他见此状马上不好意思了。于是我圆场说他提的问题很有趣,我会思考一番再答复他。     

Old Advice for New Researchers

In this paper, I offer advice to new researchers on how to conduct a successful research project in educational psychology. I break the research task into three parts: creating a research question, creating a research methodology, and creating a dissemination plan. The criteria for creating a research question include personal interest, educational relevance, theoretical grounding, and empirical testability. The criteria for creating a research methodology include that the method provides relevant evidence, is feasible, and is as simple as possible. The criteria for creating a dissemination plan include basing your argument on research evidence, presenting your argument in coherent style that links your main findings with theoretical and practical implications, and seeking the best possible peer-reviewed publication venue.     

一节数学课这样上好不好

在学校组织的“一节好课”中，我和教研组的同事一道听了一位青年教师的课，课题是：用公式法解一元二次方程。课从一元二次方程的一般形式ax^2＋bx＋c=0（a≠0）入手．用配方法得到求根公式。教师讲解得很严谨，注意到了二次项系数不为零、判别式要大于或等于零。     

From Biology to Mathematical Models and Back: Teaching Modeling to Biology Students,and Biology to Math and Engineering Students

We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge that they find difficult. To give students a sense of mastery in each area, several complementary approaches are used in the course: 1) a “live” textbook that allows students to explore models and mathematical processes interactively; 2) benchmark problems providing key skills on which students make continuous progress; 3) assignment of students to teams of two throughout the semester; 4) regular one-on-one interactions with instructors throughout the semester; and 5) a term project in which students reconstruct, analyze, extend, and then write in detail about a recently published biological model. Based on student evaluations and comments, an attitude survey, and the quality of the students'' term papers, the course has significantly increased the ability and willingness of biology students to use mathematical concepts and modeling tools to understand biological systems, and it has significantly enhanced engineering students'' appreciation of biology.

Math for the Benefit of Society: A New MATLAB-Based Gen-Ed Course

Abstract

Responding to a call for national reform of mathematical education, as well as a college-wide revision of general education (GE) requirements, we describe a new entry-level, GE course focused on the humanitarian utility of mathematics. This includes a detailed overview of how we taught the course using a Humanitarian MATLAB Lab Manual developed collaboratively with undergraduate students within an applied math program. A PRIMUS edition of this manual with complete MATLAB materials for a GE course is included as an Appendix for interested readers. A variety of social justice issues including peace-building after modern civil wars, continued cancer risk after Chernobyl, gang reduction, various dimensions of human trafficking, the use of a tractor and herbicide in subsistence farming, equitable resource distribution during the Syrian refugee crisis, and access to HIV vaccines are included in this special edition of the manual.     

加强现代数学的渗透建立工科数学教学内容新体系

本文围绕如何在工科数学教学内容改革过程中加强对学生数学素质的培养问题,结合教学改革以及教学改革试点班的教学实践,论述了了工科本科生数学教学、硕士生与博士生数学教学的课程设置以及教学内容改革方面的问题.     

新课标下中学生物探究性学习初探

运用探究性学习指导中学生物教学，教师在切实把握好教材内容的情况下，建立起民主宽松的探究性学习氛围，设计好探究性学习的问题，既可以优化课堂教学，又可以实现对学生进行创新精神的培养和实验能力的锻炼，对全面提高学生的整体素质，着眼于学生的长远利益起到了很好的作用。     

新课程背景下数学课堂的重构

要达成基础教育数学课程的目标,课堂是主阵地,必须改革传统数学课堂的弊端,重构新的数学课堂.     

新课标下中学生物课堂教学的构建

新课程标准下的中学生物课堂教学,应从学生的生活、活动出发利用各种与教学相关的媒体来构建.     

解读广告创意中的破“旧”求“新”

创意是广告的灵魂，表现独特、新意怡人的广告．能给人们留下深刻印象。广告创意是对设计者能力的挑战,它要求设计者要遵循一定的创意原则，通过分析创意的法则和特性、创意中的“新关系”，力求找到新的创意点。以达到向人们传递信息的目的，通过新关系表现新意义。     

"喜新厌旧"

“喜新厌旧”是人类的本能和天性,与之相近的词汇有“与时俱进”、“升级换代”等。“与时俱进”是近年来,在人文社会领域出现频度极高的词汇。
