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

心理学-认知(73)这个项目的目标是调查NSDL工具和服务是否支持有效地选择用于教育目的的数字资源，以及这些工具和服务是否促进了通过用户认知过程衡量的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，这两个工具的目标是识别和上下文使用资源：NSDL常规搜索和NSDL科学素养地图。该项目由犹他大学进行，提供了有关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。该项目的第一阶段使用实验室研究来考察NSDL工具对任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到实验室，在他们使用NSDL执行一系列教育任务时评估他们的认知过程和结果，第三阶段进入课堂，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。评估材料和协议被公布，以供在其他数字图书馆研究中重复使用。

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.
