公共计算机基础教学改革的新构想

公共计算机基础教学模式和教学方法等问题,已引起人们的关注。根据客观实际,可采用以下几点改革措施:参考学习使用家用电器的方法,学习计算机系统的各种基本操作;对不同专业的学生进行有针对性的办公信息自动化的教学;运用问题驱动式的教学方法,以选修课的形式进行计算机应用技术的教学。使学生学会分析问题、解决问题、扩展知识结构、开展信息处理工作的方法。

In Memoriam: Emeritus Professor Henry Oliver Lancaster, AO FAA 1 February 1913 – 2 December 2001

The death, in Sydney, of Oliver Lancaster marks the end of an era in the histories of the Statistical Society of Australia, which (in its previous existence as the Statistical Society of New South Wales) he helped found in 1947, and of the Australian Journal of Statistics of which he was founding editor (1959–1971). Oliver Lancaster was Foundation Professor of Mathematical Statistics at the University of Sydney (1959–1978), where he spent his life as student and academic. During his academic career, he achieved scholarly distinction in at least four fields: mathematical statistics, medical and public health statistics, the history of medicine and of statistics, and statistical bibliography. With E.J.G. Pitman (1897–1993), M.H. Belz (1897–1975), E.A. Cornish (1909–1973) and P.A.P. Moran (1917–1988) he was part of a cohort of renowned Australian mathematical statisticians who laid the foundation of the glory days of Australian mathematical statistics. This obituary and tribute focuses on some of these aspects, within a broader historical picture.

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

试析语感研究的现状及存在的问题

从语感研究的现状看,关涉语感本身的理论问题得到了比较深入的研究,也取得了很多成果。同时,语感作为我国第八次课程改革《语文课程标准》的核心词汇之一,语感培养问题开始真正走进人们的思维视阈。由于现实上语感实践环节的研究相对薄弱,从而造成语感教学实践成为目前语感研究面临的最大问题,其中既包括语感教学实施也包括切合实际的语感评价指标体系建立。     

视频在IP网络中传输的质量研究

利用MEPEG-4视频TRACE作为输入源,通过分析MPEG-4视频的帧特性,提出了一种针对视频质量的网络传输服务质量保证机制;搭建了视频传输的仿真系统,分析了视频在网络传输中的特性,利用PSNR作为视频质量的衡量标准,在有服务质量保证和无服务质量保证机制的两种网络环境下做了仿真并比较结果,证明了提出的方法能有效提高视频质量．     

Two point priors and Γ-minimax estimating in families of uniform distributions

It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions, a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax. The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified subintervals of the parameter space if a two point prior is least favourable in Γ.     

乡村振兴视域下陶行知乡村幼儿教育思想的当代启示

乡村振兴是一项长期持久的复杂系统工程,全面助力乡村振兴,农村幼儿教育先行。近年来,我国高度重视农村幼儿教育发展,但因多种因素制约,当前我国农村幼儿教育发展急需解决关键问题,突破诸多困境。早在20世纪二三十年代,我国人民教育家陶行知先生就已独到地认识到我国乡村幼儿教育的重要性及其存在的问题,并在实验和探索中形成了著名的乡村幼儿教育思想,这一思想与乡村振兴战略中优先发展农村教育的思想高度契合。乡村振兴视域下回顾陶行知的乡村幼儿教育思想,对于当前我国农村幼儿教育发展及全面实施乡村振兴战略具有极强的现实启示。     

加拿大不列颠哥伦比亚省基于大概念的幼小衔接课程框架及启示——以数学课程框架为例

加拿大不列颠哥伦比亚省的幼小衔接课程框架得益于大概念的统摄。以数学课程为例,对其幼小衔接课程框架进行分析,得到四点启示:幼小衔接课程的开发先要基于全局审视确认其对于立德树人、学生发展核心素养的价值意蕴;幼小衔接课程的纵向衔接要基于课程逻辑提炼大概念,保持综合课程、分科课程间的适度张力;幼小衔接课程的横向落实要基于教与学逻辑,围绕大概念构建知识、能力、传统文化等的学习标准与教学指导纲要;幼小衔接课程的持续完善要基于教育质量监测及时检验幼小衔接成效,为其修订提供决策依据。
