基于学习共同体的《教育技术学导论》——课程设计初探

文章简要地分析了教育技术导论课程的特点及其在目前的教学中存在的问题,提出以学习共同体作为学习组织形式开展教学,既可以丰富课堂教学形式,也能通过师生及同伴之间的互动,促进学习者独立思考,逐步建构自己对教育技术的理解。     

输煤控制系统硬件结构与上位机监控软件设计

根据工况将不同的设备组合成不同的工作流程，以集散控制技术为基础，应用PLC网络实现了对输煤设备的现场控制、电控室控制和中控室控制。并以FIX软件为工具，通过定义PLC的I/O端口映射表方法，以时间、事件、故障为触发手段，设计了实时监控软件，并实现了输煤量与数据库系统的数据接口。     

中国北方汉族青年ACE 基因I/ D多态性频率分布特征

通过分析与探讨汉族普通人群ACE基因I／D多态频率分布特征，试图为中国优秀耐力运动员的基因选材研究提供中国人相关人群ACE基因I／D多态频率分布的基础数据。选择18-22岁汉族学生216名作为研究对象，观察其ACE基因I／D多态频率分布。结果显示：北方汉族青年的ACE基因I／D多态频率分布，与国内相关研究结果一致，与欧美人群有非常显著差异。研究认为：从种族单一性、样本数量和年龄段的选择等因素考虑．研究结果不仅可以作为北方汉族青年ACE基因I／D多态频率分布的代表，而且对于杰出耐力的多态性标记研究来讲是理想的对照群体。

A pillar of the Youngstown community: The Public Library of Youngstown and Mahoning County engages in the Harwood practice

ABSTRACT

The Harwood Institute arrived in Youngstown, Ohio, in 1999; and today, over 18 years later, its teachings have made a profound effect upon the city. The Youngstown Public Library, through the leadership of Carlton Sears and Heidi Daniel, has wholeheartedly embraced the methods and ideology of the Harwood Institute, helping to reinvigorate and power a city working its way back to prosperity.     

The IR Has Two Faces: Positioning Institutional Repositories for Success

This article describes the ongoing efforts at University of Nevada, Las Vegas (UNLV) Libraries to evolve the role of the institutional repository (IR) and to effectively position it within the context of the Libraries’ collections, research support, and scholarly communication services. A major component of this process is re-examining the fundamental aims of the IR and aligning it to the Libraries and the campus strategic goals. The authors situate UNLV Libraries’ experience within the context of the current literature to provide background and reasoning for our decision to pursue two, at times conflicting, aims for the IR: one for scholarly communication and another for research administration.     

Teaching principles of inference with ANOVA

Analysis of variance (ANOVA) is a test of mean differences, but the reference to variances in the name is often overlooked. Classroom activities are presented to illustrate how ANOVA works with emphasis on how to think critically about inferential reasoning.     

重论"五四"新文化运动兴起的原因及其特质——一个从社会心理学角度的观察

长期以来,人们习惯于从“革命”和“启蒙”两方面去阐述“五四”新文化运动的起源与材质。第一次世界大战后中国特定的时代情绪才是这一运动爆发的直接导火线与触发剂,并以此为出发点重新梳理出“五四”新文学十年我国文学演进的脉络顺序与文学场景。     

More Powerful Tests of Simple Interaction Contrasts in the Two-Way Factorial Design

For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of statistical tests for deconstructing interaction effects when they are of primary substantive interest. Results indicate the general superiority of the modified Bonferroni procedure over Scheffé and Roy-type procedures, where the Bonferroni and Scheffé procedures have been modified to accommodate the logical implications of a false omnibus interaction null hypothesis. An applied example is provided and considerations for applied researchers are offered.
