中小学教师教育网络平台调查分析

教师专业发展网络的建设,不仅有利于广泛地共享教育资源、教学思想和教育技术,而且有利于推动素质教育和教育信息化进程。现有的中小学教师教育网络环境主要体现在教师教育网站与教师发展平台上,本文通过调查网站的功能配置、知识的结构、呈现方式和交互特征等方面,分析得出网站设计与开发者对教师学习的特点了解不足,网站知识、资源配置不够合理以及专业发展工具缺失等问题,并提出教师教育网络平台构建的一些建议。     

信息论特征选择算法的改进

特征选择在模式识别技术中起着非常重要的作用，已有多种特征选择的方法，但用信息论的方法进行特征选择还是一个新的课题，MIFS算法和MIFS-U算法都是近似算法，随着输入特征的增加，特征选择性能逐渐下降．本文通过研究这两种算法，提出一种改进方法，在运算量几乎不增加的情况下，提高这两种算法的特征选择性能。     

中国共产党对市场经济道德价值的认识

中国共产党对市场经济的道德价值已经有了辩证的认识:从正面的来看,市场经济的价值目标与共产主义的价值目标是一致的,市场经济是实现人的价值的一种形式;从负面的来看,市场经济确实容易滋生个人主义、利己主义和拜金主义,但是在社会主义的条件下,这种负面道德价值内容被局限在狭小范围内。     

主位-述位、话题-说明和信息结构

关于主位-述位（Theme-Rheme）、话题-说明（Topic-Comment）和信息结构（the InformationStructure）之间的联系有许多的争议,本文试图证明在实际话语分析中只有密切联系语言自身和使用环境,重视说话-受话两个不同的角度,方可认识到问题的关键,并对上述问题做出正确的回答.     

对信息概念的探索

学科信息概念，主要包括通讯、传播及教育领域中的信息概念，用狭义信息论对信息概念所作出的定义，存在着不足之处，在哲学中，信息概念可分为自在信息、自为信息、再生信息之分，应该从系统观的高度来认识信息概念。

A fast commonly-used algorithm of P-III distribution curve and its application

1. Introduction In drawing up the rainstorm intensity formula of a modern town to obtain the datum relation between the rainfall intensity and the rainfall time-recurrence period from original data of rainstorm intensity at different rainfall time, there are two methods: 1) the method of theoretical frequency, 2) adjusting original data with some theories or an empirical frequency curve. The second method is usually adopted based on a great quantity of project practices done by predecessors. …

Academics’ perceptions of the benefits and challenges of self and peer assessment in higher education

Despite compelling evidence of its potential effectiveness, uptake of self and peer assessment in higher education has been slower than expected. As with other assessment practices, self and peer assessment is ultimately enabled, or inhibited, by the actions of individual academics. This paper explores what academics see as the benefits and challenges of implementing self and peer assessment, through the analysis of interviews with 13 Australian academics. Thematic analysis of our qualitative data identified seven themes of benefits and five challenges. Our academics showed strong belief in the power of self and peer assessment as formative assessment, contrary to past literature which has focussed on the accuracy of students’ marking. This paper therefore brings insights as to not only what academics value about self and peer assessment but also identifies potential inhibitors in practice. Recommendations are made about improving the design and implementation of self and peer assessment in higher education.
