PREDICATE Project: Targeted Research on Teacher Creativity at the Intersection of Content, Student Cognition, and Digital Media

这个有针对性的研究项目正在调查一种方法对K-12数学教师专业发展的影响，这种方法依赖于通过制作简短的解释性视频来明确培养教师的创造力，以帮助学生学习数学概念。所有视频都是可重复使用和共享的，使用符合nsdl的标准，这样它们就可以随着时间的推移积累成大量的和可共享的个人资源集合。这项研究的基础是一种新兴的个性化学习社区理论，以及在美国国家科学基金会计算机与信息科学与工程理事会和教育部教育科学研究所的支持下开展的试点工作。本研究的对象包括初高中数学教师、本科师范教育和数学教师；各类学习科学、数学教育、政策及创意研究团体的成员；以及个人在专业发展政策和决策中的作用。该项目的智力价值源于其潜在的理论基础，包括课堂动态的先前研究，当前关于数字图书馆资源与教师专业发展整合的试点工作，以及对数字图书馆影响的系统研究。该项目正在发挥更广泛的影响，为教师参与NSDL的资源收集、适应和生成以及某些类型资源库的可用性提供以创造力为中心的方法。此外，这种影响延伸到其对本科数学系职前教师教育的潜在影响。

This Targeted Research project is investigating the impact of an approach to K-12 professional development for mathematics teachers that rests on the explicit cultivation of teacher creativity in producing short explanatory videos to help engage students in learning mathematics concepts. All videos are reusable and shareable using NSDL-compliant standards so that they may accumulate over time into substantial and sharable personal resource collections. Underlying this research is an emerging theory of personalized learning communities and pilot work carried out with support from NSF's Computer and Information Science and Engineering Directorate and the Department of Education's Institute for Education Sciences. Target audiences for this research include middle and high school mathematics teachers, undergraduate teacher education and mathematics faculty; members of various learning science, mathematics education, policy and creativity research communities; and individuals in professional development policy and decision-making roles. The project's intellectual merit stems from its underlying theory base involving prior research in classroom dynamics, current pilot work on the integration of digital library resources with teacher professional development, and a methodical approach to research on digital library impact. The project is exerting broader impacts by contributing creativity-centric approaches to teacher participation in resource collection adaptation and generation to NSDL and to the usability of certain types of resource libraries. Additionally, this impact extends to its potential influence on pre-service teacher education in undergraduate mathematics departments.
