Developing Guidelines for Using Digital Media Visualization Resources to Support Student Inquiry in Online Laboratory Investigations

跨学科（99）本项目的目标是研究可视化技术在在线实验室学习环境中的有效性，以及一般情况下，将媒体整合到广泛的网络学习工具中。预期成果包括一套指导方针，将可视化整合到一个标准化的在线实验室用户界面中;协助课程开发人员和教师确定在支持学生学习真实科学探究方面最有用的可视化类型;并指导他们在NSDL存储库中搜索适当的可视化资源。该项目侧重于学习经验可以通过提问有效地设计：关于支持学生学习所需的可视化类型;关于每个可视化和伴随活动放置在学习序列中的位置;关于让学习者选择他们是否在查询过程中的特定点被引导到特定可视化，或者是否允许他们自行选择查看哪个可视化。通过制定具体的指导方针，该项目有可能改善将适当的可视化整合到学生的科学调查活动中，支持个性化的学习路径，并适应不同的学习方法。该项目期间制定的指导方针与NSDL技术网络服务组，教师领域或其他NSDL档案的所有最终用户共享。它们提供了更多的描述性元数据，改善了从这些存储库中搜索和选择适当的可视化，并可以作为一个模型，用于改善各种学习环境中的资源整合。

Interdisciplinary (99)The objective of this project is to study the efficacy of visualization techniques in an online laboratory learning environment and, in general, the integration of media into a wide range of cyberlearning tools. The expected outcomes include a set of guidelines for integration of visualizations into a standardized online lab user interface; on assisting curriculum developers and teachers in identifying the types of visualizations that are most useful in supporting student learning in an authentic scientific inquiry; and on guiding their search for appropriate visualization resources in NSDL repositories.This project focuses on the ways in which learning experiences can be effectively designed by asking questions: about types of visualizations needed to support student learning; about the place in the learning sequence where each visualization and accompanying activity is placed; about giving a choice to learners whether they are directed to specific visualizations at specific points in the inquiry process or whether they are allowed to choose which visualization to view at their discretion. By producing specific guidelines, this project has a potential to improve the integration of appropriate visualizations into student scientific investigation activities, support individualized learning paths, and accommodate different learning approaches.The guidelines developed during this project are shared with the NSDL Technical Network Services Group, all end-users of Teachers' Domain or other NSDL archives. They provide more descriptive metadata that improves the search and selection of appropriate visualizations from these repositories and can serve as a model for improving resource integration in a wide range of learning contexts.
