Of Frogs & Rhetoric: The Atrazine Wars

In a scientific dispute over the effects of atrazine on amphibians, chemical industry–funded and publically funded scientists present stunningly contrasting constructions of atrazine's environmental concentrations, persistence, and potential to harm. Considerable scientific uncertainties and variable ranges allow authors to construct preferred versions of the story of atrazine. These incommensurate rhetorical constructions, more the result of competing economic and environmental interests than of any paradigmatic misalignments, have prolonged the dispute not only over atrazine's effects but also over whether its sales should be banned.     

高校学生党支部工作的几点思考

我们该怎样做研究——对课程与教学论主流研究范式的反思

重理论思辨、轻实践研究,研究方法简单粗糙,是当前课程与教学论主流研究范式的两大缺陷。欠缺科学精神、方法意识薄弱、评价机制不健全,是造成当前主流研究范式缺陷的主要原因。基于此,应从六个方面改善课程与教学论主流研究范式:关注对实践问题的微观研究和行动研究;加强方法意识,融入科学精神;建立课程与教学论的方法论体系;转变研究思维方式;改善现有评价体系;加强研究生培养过程中方法意识的培养和方法训练。     

信息技术与新型教学模式的构建

随着信息技术的进步,结合传统教学、实践教学和实验教学模式进行的新型教学模式出现,各种媒体被先后运用到了教学中,使教学变得灵活多样,丰富了课堂教学方式,提高了教学质量。以计算机为中心的互联网、多媒体技术的崛起,给现代教育注入了新的生命,在教育体制、教育方针、教育模式等各方面带来巨大的变革。从理论与现实的角度对信息技术在教学模式中所起的重大作用做出梳理,并指明新型教学模式实现的途径。

An NCME Instructional Module on Data Mining Methods for Classification and Regression

Data mining methods for classification and regression are becoming increasingly popular in various scientific fields. However, these methods have not been explored much in educational measurement. This module first provides a review, which should be accessible to a wide audience in education measurement, of some of these methods. The module then demonstrates using three real‐data examples that these methods may lead to an improvement over traditionally used methods such as linear and logistic regression in educational measurement.     

Exploring Developmental Appropriateness of Multitouch Tables in Prekindergarten: A Video Analysis

This study explored how developmentally appropriate practices influenced the affordances of a multitouch surface in an early childhood classroom. Children, ages 4 to 5 years old, were videotaped while engaged in a storymaking application on a multitouch table. As a result of the study, we found that some challenges with the functionality undermined children's autonomous control. The researchers observed numerous instances of issues with control of the medium, including height of the table, sensitivity to multiple types of touch, and limited instructions and prompts. Implications for future research and practice are discussed.     

影响山西高职高专田径队发展的因素研究

A Process for Reviewing and Evaluating Generated Test Items

Testing organization needs large numbers of high‐quality items due to the proliferation of alternative test administration methods and modern test designs. But the current demand for items far exceeds the supply. Test items, as they are currently written, evoke a process that is both time‐consuming and expensive because each item is written, edited, and reviewed by a subject‐matter expert. One promising approach that may address this challenge is with automatic item generation. Automatic item generation combines cognitive and psychometric modeling practices to guide the production of items that are generated with the aid of computer technology. The purpose of this study is to describe and illustrate a process that can be used to review and evaluate the quality of the generated item by focusing on the content and logic specified within the item generation procedure. We illustrate our process using an item development example from mathematics drawn from the Common Core State Standards and from surgical education drawn from the health sciences domain.
