数学文化渗透数学课堂教学的探索

高中即将实施的新课标中明确提出要将数学文化融入课程内容之中,课堂是课程的落脚点,数学文化融入课程首先要让数学文化走进课堂.数学文化是以数学学科为核心,不仅包括数学知识、方法、思想,还包括数学精神、数学史、数学审美与数学应用价值,教师不可将数学文化狭隘成数学史.     

关于数学知识育人寓意成分之思考

在我国"应试教育"向"素质教育"转换的进程中,数学教学(教育)不仅要传授知识、技能、思维,还应发挥数学的文化价值.数学素养是数学教育改革的目标,是提高数学教育质量的关键.本文以曲线积分为案例,探索题目的育人寓意:抽象的圆柱螺旋线曲线积分、成长轨迹与抗压弹能力.思考数学教育除培养学生数学理论知识、数学思维外,如何让学生在学习知识、锻炼思维中体会知识所蕴含的育人智慧,并把此作为数学教育的一个人文维度.案例可看作是数学文化与数学课融合的一个范例,仅是呈现数学知识另一功能的一种方式,更多潜在的功能需要不断的挖掘和认知.素质教育的推进重要的是育人理念和数学文化意识的融合.注重数学教学过程中的知识与技能,更注重多科知识与文化的融合,期待创设科学与人文相融合的一种富有生命力的螺旋式教育生态环境.     

隐形的翅膀——“二次函数与一元二次方程”送教下乡教学实录与点评

1 引言数学教学有两条线,一条是数学知识教学的明线,一条是数学思想方法渗透的暗线.数学知识的学习是基础,数学思想方法的形成是基础知识的升华,是将数学知识的学习引向深入.初中阶段学习数学,除了掌握必须的"双基",还要了解数学知识的生成背景和发生过程,深入体会其中的思想方法,从有形的数学知识中探寻无形的数学思想方法,让数学思想方法转化成"隐形的翅膀",完成数学学习中的智慧托举.     

高阶思维是数学可视化教学的重要着力点

教师通过可视化技术开展数学教学是一种重要的教学方式,数学问题的动态可视可以提升教师"教"的效度,还可以帮助学生更好地认识数学知识,数学可视化带来了教学便利的同时,也引发思考:数学可视化教学的着力点是什么?本文以微专题教学案例的形式指出:高阶思维应是数学可视化教学的重要着力点.     

借助现代信息技术手段 促进数学文化融入“大学文科数学”的教改

对于文科学生,在掌握基本数学知识的前提下,大学数学课程"工具"的作用是相对次要的,"了解数学文化,培养理性思维"的作用则是更加重要的.南开大学在加强和改进现代信息技术手段,发挥文科学生擅长形象思维的优势,将数学文化融入文科数学教学方面取得了较好的效果.     

基于广西少数民族文化的小学数学课程资源的开发

以广西少数民族文化为依托,以中小学数学知识为载体,探索了基于广西少数民族文化的小学数学课程资源开发.以《用数学的眼光了解广西》拓展课为实践案例,将民族文化融入数学课程与教学,引导学生在真实情景中发现问题、解决问题.在感受民族文化的过程中领略我国少数民族的智慧,增强民族自豪感.     

核心素养渗透数学课程教学北大核心

本文从画五角星谈起,通过具体的数学教学案例,说明核心素养不是强加于课程之外的额外负担和无病呻吟．而应该渗透在具体数学内容的教学过程中,成为引导学生理解和应用数学知识的指路明灯和导航仪．     

基于“数学思想方法”的“同底数幂的乘法”教学探索

1引言数学思想方法是处理数学问题的指导思想和基本策略,是数学的灵魂.以数学知识为载体揭示其内容中蕴涵的数学思想方法,是帮助学生理解数学、提高思维水平和解决问题能力的需要,是现代教学思想与传统教学思想的根本区别之一.数学思想方法是基于数学知识又高于数学知识的一种隐性的数学知识,而认识隐性知     

数学实验,促进初中数学的知行合一

"实验"在现代汉语中的解释是:为了检验某种假设或理论而进行的某种操作活动.数学实验是指在数学理论的指导和数学思维的参与下,借助实验仪器、实物、三角板、几何模型或几何画板等操作,让学生通过模拟、分析、归纳、概括、交流、总结、推理等实践活动,理解抽象数学知识、检验数学猜想或解决数学问题.相比于传统教学,数学实验可有效地让学生经历知识的生成过程,使学生在"做"与"思考"中获得知识、积淀经验和体悟方法,从而强化学生对数学知识的掌握及对数学的情感体验,促进学生的知行合一.     

Affine-inscribed and affine-circumscribed polygons and polytopes

Five theorems on polygons and polytopes inscribed in (or circumscribed about) a convex compact set in the plane or space are proved by topological methods. In particular, it is proved that for every interior point O of a convex compact set in ℝ³, there exists a two-dimensional section through O circumscribed about an affine image of a regular octagon. It is also proved that every compact convex set in ℝ³ (except the cases listed below) is circumscribed about an affine image of a cube-octahedron (the convex hull of the midpoints of the edges of a cube). Possible exceptions are provided by the bodies containing a parallelogram P and contained in a cylinder with directrix P. Bibliography: 29 titles.

Partitions and pairwise sums and products

A seven cell partition of N is constructed with the property that no infinite set has all of its pairwise sums and products in any one cell. A related Ramsey Theory question is shown to have different answers for two and three cell partitions.     

Linear birth and death models and associated Laguerre and Meixner polynomials

We study birth and death processes with linear rates λ_n = n + α + c + 1, μ_{n + 1} = n + c, n 0 and μ₀ is either zero or c. The spectral measures of both processes are found using generating functions and the integral transforms of Laplace and Stieltjes. The corresponding orthogonal polynomials generalize Laguerre polynomials and the choice μ₀ = c generates the associated Laguerre polynomials of Askey and Wimp. We investigate the orthogonal polynomials in both cases and give alternate proofs of some of the results of Askey and Wimp on the associated Laguerre polynomials. We also identify the spectra of the associated Charlier and Meixner polynomials as zeros of certain transcendental equations.     

Distributive and Multiplication Modules and Rings

We study rings in which every ideal is a finitely generated multiplication right ideal.     

Beliefs and beyond: affect and the teaching and learning of mathematics

The importance of beliefs for the teaching and learning of mathematics is widely recognized among mathematics educators. In this special issue, we explicitly address what we call “beliefs and beyond” to indicate the larger field surrounding beliefs in mathematics education. This is done to broaden the discussion to related concepts (which may not originate in mathematics education) and to consider the interconnectedness of concepts. In particular, we present some new developments at the conceptual level, address different approaches to investigate beliefs, highlight the role of student beliefs in problem-solving activities, and discuss teacher beliefs and their significance for professional development. One specific intention is to consider expertise from colleagues in the fields of educational research and psychology, side by side with perspectives provided by researchers from mathematics education.
