Is there an educational advantage to NSDL? Assessing impact on cognitive processes and learning outcomes during resource selection and use.

这个项目的目的是调查NSDL工具和服务是否支持为教育目的而有效地选择数字资源，以及这些工具和服务是否通过用户的认知过程来促进这些资源的成功学习。预期结果包括与两个主要的NSDL工具相关的学习结果的详细分析，这些工具的目标是资源的识别和上下文使用：NSDL通用搜索和NSDL科学素养地图。这个项目由犹他大学进行，提供了关于数字图书馆工具如何通过网络上的分布式学习对象促进有效学习的关键数据。项目的第一阶段使用实验室研究来检查NSDL工具对职前教师搜索和使用教育数字资源的影响，第二阶段将在职教师带入实验室，评估他们使用NSDL执行一系列教育任务时的认知过程和结果，第三阶段转移到教室，评估NSDL工具对学生思维和学习的影响。该项目的更广泛影响是更好地了解NSDL技术和资源的教育有效性，并就更有效的工具和服务设计提出建议，以促进对学习过程和结果的积极影响。评估材料和协议已发布，供其他数字图书馆研究重用。

Psychology - Cognitive (73)The objective of this project is to investigate whether NSDL tools and services support efficient selection of digital resources for educational purposes and whether these tools and services promote successful learning with these resources as measured by users' cognitive processes. The expected outcomes include a detailed analysis of the learning outcomes associated with two major NSDL tools that target the identification and contextual use of resources: NSDL General Search and NSDL Science Literacy Maps. This project, conducted by the University of Utah, provides critical data about how digital library tools can promote effective learning with distributed learning objects on the Web. Phase 1 of the project uses a laboratory study to examine the influence of NSDL tools on pre-service teachers as they search for and use educational digital resources, Phase 2 brings in-service teachers into the lab, assessing their cognitive processes and outcomes as they use NSDL to perform a series of educational tasks, and Phase 3 moves to the classroom, assessing the impact of NSDL tools on student thinking and learning.The broader impact of this project is a better understanding of the educational effectiveness of NSDL technologies and resources as well as recommendations on more effective tool and service design to promote positive impact on learning processes and outcomes. The evaluation materials and protocols are published for reuse in other digital library research.
