SIMPLE Science: Image-based learning tools for K-12 education

这个项目对NSDL做出了贡献，它克服了在K-12教育中主流使用图像处理和分析(IPA)的障碍。该系统(1)使主流教育工作者和公众能够接触到IPA，作为一种易于使用的学习工具；(2)使教育工作者能够查阅广泛和可更新的成像数据档案；(3)提供一种教学结构，帮助教育工作者以支持达到特定国家教育标准的方式使用成像数据。该项目创建了一个三层结构，支持学生使用IPA，从如何在科学的各个领域使用成像的基本探索，到对可从档案中获得的数据的原始研究。第一层以教程为特色，指导学生通过案例研究复制由领先的成像科学家进行的研究，并解释成像科学中的关键概念。第二级以在线形式实施现有材料的更新版和基于指导发现方法的新课程。第三级为学生和教师提供了一种结构，以使用档案图像以及来自选定互联网来源的图像进行自我指导的研究。来自美国各地的学校、教师和学区已被招募为该项目的测试员，代表了预计将使用最终系统的教育工作者和学生的各个阶层。可持续性问题的解决办法是制作软件的CD-ROM版本和资源，供在线销售和通过现有经销商销售。对于网站提供的课程和资源，还可以通过“按许可证付费”服务获得额外的在线订阅。所有开发的材料都可以免费提供给NSDL开发人员。国家科学基金会数学和物理科学局的多学科活动办公室正在为这一项目提供大量共同资金，以认识到数字图书馆对支持这一项目的重要性，以便为教师和学生改进工具，采用和生成图像处理和分析资源。

This project develops a contribution to the NSDL that overcomes barriers to mainstream use of image processing and analysis (IPA) in K-12 education. The system (1) makes IPA accessible to mainstream educators and the public as an easy to use tool for learning; (2) affords access by educators to extensive and updateable archives of imaging data; and (3) provides a pedagogical structure that helps educators use imaging data in a manner that supports attainment of specific national education standards. The project creates a three-tiered structure that supports student's use of IPA from basic explorations of how imaging is used in various fields of science to original research on data available from an archive. The first tier features tutorials that guide students through case studies replicating research conducted by leading imaging scientists and explains key concepts in imaging science. Tier two implements, in an online format, updated versions of existing materials and new lessons based on guided-discovery approaches. Tier three provides a structure for students and teachers to conduct self-guided research using archive images as well as images from selected Internet sources. Schools, teachers, and districts from across the United States have been recruited to be testers for the project, representing a cross-section of the educators and students who can be expected to use the finalized system. Sustainability is addressed by producing CD-ROM versions of the software and resources for sale online and via established resellers. Additional online subscription is available through a "pay-per-license" service for lessons and resources provided by the Web site. All of the developed materials are available to NSDL developers at no cost. The Office of Multidisciplinary Activities in the NSF Directorate for Mathematical and Physical Sciences is providing significant co-funding of this project in recognition of the importance of a digital library for the support of this project to enhance tools and adopt and generate resources for image processing and analysis for teachers and students.
