1 引 言自八十年代以来 ,高等院校的几乎所有专业 ,无论是理工科还是文科专业均开设了高等数学这门课程 .由近几年来我国高等院校招生人数看 ,每年大约有超过百万的大学生在接受高等数学的教育 .这正是现代社会对人才的要求的体现 ,也是数学重要作用的体现 .关于理工科高等数学 ,各高等院校均花大力气进行了教材、教学等各方面的研究与改革 ,而由于文科高等数学课程开设的时间还不长 ,因此对它的教材、教学等方面的研究还很缺乏 .据统计 ,目前我国接受文科高等数学教育的人数几乎等于接受理工科高等数学教育的人数 .因此 ,对文科高等数… 相似文献

基础学科的教材直接影响学生的基本功,尤其是几乎每个学科都会涉及的数学类教材,如矩阵论.矩阵论是研究生的基础课程,在对学生以后的学术道路有举足轻重的作用.所以选择一本合适的教材,对学生和教师来说都有不小的帮助.然而,对教材的评价而言,不能单单从一个方面入手,因此将模糊综合分析法与层次分析法结合,在矩阵论教材的评价方面建立评价体系,为高校选择合适的教材提供依据. 相似文献

随着我国高等教育的迅速发展,特别是本科教育规模的迅速扩大,高等教育面临着前所未有的机遇和挑战.清华大学萧树铁教授以自己从事数学教学和科研的体会,深刻地分析了"大学数学"教学的现状.要实现高等教育的可持续发展,培养有创新意识和创新能力的高级人才,基础课教学的质量是重点和关键.数学类课程是理工科基础课的基础,随着科学和技术的发展,数学类基础课为适应时代的发展正不断地进行着教学改革,如何改革没有统一的标准.对于普通本科和独立学院的数学类之间联系也没有进行过比较研究.下面结合我院的普通本科和独立学院的数学类基础课程教学进行比较分析. 相似文献

教材是教师教学的重要课程资源之一,教师对教材理解程度、处理方式和加工水平的高低既反映教师学科专业功底的厚薄,也直接关系到课堂教学质量的优劣.新课程将高中数学内容划分为不同模块或专题,但数学是一个不可分割的整体,教师应既"身在"模块又"胸怀"整个数学课程,既基于模块但同时又能"跳出"模块,从课程整体的视角实施教学.本文结合"抛物线的标准方程"(苏教版普通高中课程标准实验教科书选修2-1)一节的教学案例,提出优化模块教学、从教材处理到教学实施的三部曲,即教材的解读要"深化",教材加工要"细化",教学设计要"优化". 相似文献

Under study is the class of ring Q-homeomorphisms with respect to the p-module. We establish a criterion for a function to belong to the class and solve a problem that stems from M. A. Lavrentiev [1] on the estimation of the measure of the image of the ball under these mappings. We also address the asymptotic behavior of these mappings at a point. 相似文献

Let $\mathcal{G}(z):=\sum_{n\geqslant0} z^{2^{n}}(1-z^{2^{n}})^{-1}$ denote the generating function of the ruler function, and $\mathcal {F}(z):=\sum_{n\geqslant} z^{2^{n}}(1+z^{2^{n}})^{-1}$ ; note that the special value $\mathcal{F}(1/2)$ is the sum of the reciprocals of the Fermat numbers $F_{n}:=2^{2^{n}}+1$ . The functions $\mathcal{F}(z)$ and $\mathcal{G}(z)$ as well as their special values have been studied by Mahler, Golomb, Schwarz, and Duverney; it is known that the numbers $\mathcal {F}(\alpha)$ and $\mathcal{G}(\alpha)$ are transcendental for all algebraic numbers α which satisfy 0<α<1. For a sequence u, denote the Hankel matrix $H_{n}^{p}(\mathbf {u}):=(u({p+i+j-2}))_{1\leqslant i,j\leqslant n}$ . Let α be a real number. The irrationality exponent μ(α) is defined as the supremum of the set of real numbers μ such that the inequality |α?p/q|<q ?μ has infinitely many solutions (p,q)∈?×?. In this paper, we first prove that the determinants of $H_{n}^{1}(\mathbf {g})$ and $H_{n}^{1}(\mathbf{f})$ are nonzero for every n?1. We then use this result to prove that for b?2 the irrationality exponents $\mu(\mathcal{F}(1/b))$ and $\mu(\mathcal{G}(1/b))$ are equal to 2; in particular, the irrationality exponent of the sum of the reciprocals of the Fermat numbers is 2. 相似文献

LetT be a positive linear operator on the Banach latticeE and let (S
n
) be a sequence of bounded linear operators onE which converge strongly toT. Our main results are concerned with the question under which additional assumptions onS
n
andT the peripheral spectra (S
n
) ofS
n
converge to the peripheral spectrum (T) ofT. We are able to treat even the more general case of discretely convergent sequences of operators. 相似文献
