线性离散系统的H∞开环迭代学习控制器设计

针对线性离散系统,研究了开环动态迭代学习控制律的设计问题.首先给出了闭环系统的收敛充分条件,然后把迭代控制转化为H∞设计问题,最后利用线性矩阵不等式（LMI）方法求解迭代学习控制器.通过仿真实例表明了设计方法的有效性.     

基于网络环境下协作学习模式的构建和实践

随着信息技术的发展，网络环境已成为学习者学习的重要环境之一。基于网络环境下的协作学习，能够激发学习者的学习动机，消除学习的孤独感，有利于培养学习者之间的合作交流能力和创新能力，增强互助意识，提高学习效率。文章从协作学习的概念和特点入手，介绍了协作学习的四个基本要素，分析了协作学习的几种模式，探讨了基于网络环境下协作学习的教学设计和实施。     

影响与促动:科学思潮与"五四"小说的启蒙话语

科学知识的广泛传播以及科学救国风尚的盛行,引发了"五四"科学思潮的勃兴.当时崇尚科学的浓厚文化语境,既促发了"五四"小说家们利用民主思想对民众进行启蒙,又注重运用科学的精神与方法来达到启蒙的效用.提倡科学理性精神,以科学为武器消除民众愚昧落后的思想意识;唤其觉醒,而建立新的社会文明,是科学思潮对"五四"小说启蒙话语影响的重要体现.     

Nonscience majors learning science: A theoretical model of motivation

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

实验教学改革的新思路—"导师制"

“导师制”人才培养方案是一种集科研和实验教学为一体的开放式实验教学。是一种以探索性为主体的主动性学习。它有利于发掘和提高大学生的综合素质,推动高校全面素质教育改革的深入。因此它十分适合于如生命科学等理科学生的人才培养。     

齐国兵学文化与《孙子兵法》

齐国大地军事家辈出,兵法著作内容宏富,孙武生长于泱泱大国的古老齐国,齐国是中国的兵学发源地,先秦的主要兵书出自齐地,孙武的兵学思想上承源远流长的齐国兵学传统流脉,深深承受于地域文明滋养,深深打上了齐文化的印痕。在中国兵学发展历史上,从姜尚到孙武再到其后的孙膑,形成了源远流长而又一脉相承的齐国兵学文化传统。     

多维视角中的学习不良研究

目前的学习不良现象的研究,理论视点多集中在心理学和教育学领域。而在急遽变动的多元化社会中,对学习不良现象的研究需要建立多重分析框架,从情境视角、互动视角和反思视角等不同的视角来进行。     

How do university teachers combine different approaches to teaching in a specific course? A qualitative multi-case study

Teaching approaches in higher education are at the general level well researched and have identified not only the two broad categories of content-focused and learning-focused approaches to teaching but also consonance and dissonance between the aspects of teaching. Consonance means that theoretically coherent teaching practices are employed, but dissonance occurs when two broad approaches are combined. Previous studies researched teaching approaches at the general level, whereas the present study, researched approaches to teaching at the course level. Three university teachers were interviewed in depth about their teaching approach to one particular course. Data were analyzed using qualitative content analysis. While previous studies have found that dissonance occurs between different aspects of teaching, this multi-case study revealed that dissonance can also be found within a single aspect. The present study suggests that neither content- nor learning-focused approaches to teaching are mutually exclusive and therefore may co-exist in individual teachers’ practices.     

英语教学中如何实施文化背景知识教学

语言有着丰富的文化内涵。在英语教学中,文化主要指英语国家的历史,地理,风土人情,传统习俗,宗教信仰,生活方式,行为规范和价值观念等。针对忽视文化背景知识所造成的英语教学和教材中的问题,本文将从听、说、读、写、译五个方面浅谈如何在英语教学中灌输英语国家文化背景知识,而不是简单地教授语言知识和技能,从而实现跨文化交际教学法。只有这样学生才能在英语学习中具有全球视野,不仅学到英语语言知识,而且学到文化背景知识。     

构建课堂教学管理学的几个理论问题

从管理角度对课堂教学进行探讨的历史由来已久 ,只是未曾提升到学科认识的高度。时代的发展使教师的课堂管理职能愈来愈突现出来 ,因而构建课堂教学管理学渐趋必然。该学科不同于教学论 ,亦有别于学校管理学 ,它将以独立的学术地位和独特的结构体系展示其存在价值
