A Web-Based Writing and Peer Review Component in Introductory Earth Science Classes: Adaptation of the Calibrated Peer Review Tool Used in Chemistry

这个概念验证项目正在设计和评估三个原型校准同行评审（CPR）作业，用于地球和环境科学入门课程。CPR是一种技术写作工具，由加利福尼亚的一个机构联盟建立，由大学和学院的化学和生物系使用。这种教学评估工具采用基于网络的交互式方法，允许学生通过撰写及时、相关的主题来提高理解能力。学生们撰写短文，并以一种既省时又有效的方式复习同学们的文章。该CPR项目正在为三个基于地球科学的作业实施数字工具，为学生的输入提供管理审查、分析、评估，并为学生和教师准备报告。目前正在利用Lexis-Nexis新闻数据库，以确定内容丰富且从公民的角度看具有相关性的主题。利用这个可搜索的资源，三个特别相关的主题被使用：地震和板块边界、全球变暖的证据和洪水灾害。目前正在与参与CPR项目的一组教员建立合作关系，以促进pi利用现有的技术基础设施，并帮助开发一种适合全国地球科学部门使用的媒介。该项目正在爱荷华州立大学进行评估，并由社区学院、面向本科的州立学院和一所研究型大学的讲师进行评估。

This proof-of-concept project is designing and evaluating three prototype Calibrated Peer Review (CPR) assignments for use in introductory Earth and environmental science classes. CPR is a technical writing tool established by a consortium of institutions in California and used by chemistry and biology departments at universities and colleges. This instructional assessment tool employs an interactive web-based approach thatallows a student to develop increased understanding by writing about timely, relevant topics. Students develop short essays and review their peers' essays in a manner that is both time-efficient and effective. This CPR project is implementing digital tools for three Earth science-based assignments providing managed review, analysis, assessment of student input, and preparation of reports for both student and instructor. Central to the identification of topics that are content-rich and, from a citizens' perspective, relevant, the Lexis-Nexis news database is being utilized. Using this searchable resource, three topics of particular relevance are being used: earthquake and plate boundaries, evidence for global warming, and flood hazards. Collaboration with a group of faculty involved in the CPR project is being established to facilitate the PIs use of available technological infrastructure and to help develop a medium appropriate for use by Earth science departments nationwide. The project is being evaluated at Iowa State University and by instructors at a community college, undergraduate-oriented state college, and a research university.
