Interpreting and using student ratings data: Guidance for faculty serving as administrators and on evaluation committees

This article is about the accurate interpretation of student ratings data and the appropriate use of that data to evaluate faculty. Its aim is to make recommendations for use and interpretation based on more than 80 years of student ratings research. As more colleges and universities use student ratings data to guide personnel decisions, it is critical that administrators and faculty evaluators have access to research-based information about their use and interpretation.The article begins with an overview of common views and misconceptions about student ratings, followed by clarification of what student ratings are and are not. Next are two sections that provide advice for two audiences—administrators and faculty evaluators—to help them accurately, responsibly, and appropriately use and interpret student ratings data. A list of administrator questions is followed by a list of advice for faculty responsible for evaluating other faculty members’ records.     

高中实验教科书使用情况跟踪调研的实施构想

为了给新一轮高中教科书的修订提供参考,笔者通过评述国内外教科书评价体系的研究成果,尝试提出一种由4个领域、8个维度、99项标准组成的高中实验教科书使用情况跟踪调研框架。在此基础上从调研方式、调研工具、调研样本、调研进度4个方面阐述了跟踪调研的总体实施构想,期待能为新一轮高中实验教科书的修订工作提供具有操作性的建议。     

大幅面绘图仪的使用与维护

大幅面绘图仪是现代工程图档的主要输出设备,在绘图软件的支持下可绘制出复杂、精确的图形,是各种计算机辅助设计不可缺少的工具。以惠普公司的HP Designjet T1100绘图仪为例,介绍大幅面绘图仪的使用和维护技巧。     

从编校视角辨析“的、地、得”的用法

＂的、地、得＂在文稿中出现的频率很高,但许多人尚不能完全准确地使用它们。究其原因,主要是对＂的、地、得＂的词性不清楚、语法特点不熟悉和用法缺乏了解。因此,作者和编辑必须高度重视用词的规范性,加强汉语语法学习,以避免误用。     

跨国技术转移和扩散对国家创新能力的作用机理及相关关系——来自中国的经验证据

跨国技术转移与扩散对国家创新能力的作用日益明显。在理论分析的基础上,以中国为例,实证检验跨国技术转移和扩散与国家创新能力的相关关系。通过研究,得出如下结论:(1)跨国技术转移和扩散与国家创新能力是高度正相关的,加速跨国技术转移与扩散能够有效提升国家创新能力;(2)跨国技术转移与扩散的3个关键要素(国际贸易、外国直接投资、跨国研发机构嵌入)对国家创新能力的促进作用存在相互依赖关系;(3)跨国技术转移与扩散对国家创新能力的作用机理可以以国际贸易、外国直接投资和跨国研发机构嵌入3个要素予以解释,形成了"234"结构的9条提升路径。     

基于彩色图像的可逆数据隐藏评价算法

可逆数据隐藏是继密码学、传统的数据隐藏算法之后的又一项重要技术,主要应用在军事、医学等特殊领域。近几年可逆数据隐藏算法层出不穷,但数据嵌入的核心思想大同小异,算法优劣的比较不是很明显。针对这一问题,文章提出了一种新的关于可逆数据隐藏的算法比较方案,实验证明该方案能够较好地分析出可逆数据隐藏算法的优劣,具有一定的实用价值。     

《红楼梦》中的“没的”研究

《红楼梦》(前80回)中的"没的"的用法与其早期的用法一样,存在"没的1"、"没的2"和"没的3"这三种不同的形式,但与之前的用法也有不少差别。"没的"在《红楼梦》中出现的次数并不多,用法也趋向于单一,说明这个时期的"没的"已经处于衰落期,没有早期的复杂多样的使用情况了。     

Popular with whom? Usage demographics of popular science nonfiction at an academic library

Abstract

There is a large body of nonfiction written for a general audience which is infrequently promoted in popular reading collections at academic libraries. The aim of this research is to look at the usage of nonfiction science literature at a large university library in comparison to the science collection as a whole. This information can help librarians to not only determine how best to prioritize the collection of nonfiction science literature, but it can also be used to provide insight into how popular nonfiction science books can be most effectively promoted to library patrons.     

Marketing Electronic Resources and Services

Summary

In an effort to provide desktop access to information at Texas A&M University, an increasingly greater portion of the University Libraries' budget is being spent on electronic resources and services. This study, a survey of a random sample of the faculty and teaching staff, was designed to determine if these resources and services are being used by the targeted population and, if not, why. The results of the study indicate that a lack of information is the greatest obstacle to the use of electronic resources/services, and they suggest that the Libraries should place greater emphasis on outreach to the faculty and improved marketing strategies.     

The “80/20 Rule” and Core Journals

This column examines the 80/20 rule, also termed a Pareto distribution, and explains these terms' historical origins. The column focuses on this pattern in the use of print serials, downloads from electronic databases, and citations to journals. The rule's relationship to Bradford's Law is explored, and some of the research pertaining to the 80/20 rule is reviewed. The pattern's utility for defining the core collection and serials collection management is discussed, whereas a number of limitations are pointed out. Some questions for further research are suggested. It is concluded that the 80/20 ratio (80% of use is derived from 20% of the titles), when found as an approximate pattern, is a valid method for determining the core concept in journal collection management.
