Next Generation Preschool Math

在这个完整的研究和开发项目中，教育发展中心和SRI国际的学习科学家和媒体研究人员团队将与WGBH的教育媒体制作人合作，开发，测试和完善课程补充（一项动手技术），（1）促进儿童对数字的理解（计数、比较和排序）和公平共享（均分）;（2）在新兴的手持平台上使用交互式媒体（触摸屏平板电脑），将新的多点触摸活动与现有的动手活动相结合;（3）通过与成人导游和同龄人分享使用互动媒体，增加学习机会;以及（4）为学前教育工作者提供专业和技术支持材料。 该项目调查了是否以及如何参与媒体丰富的课程补充活动，提高低收入幼儿的早期学习数量和均分。该项目以关于学习轨迹的健全研究为基础，编写促进幼儿学习的材料。 此外，该项目还将产生新的研究成果，说明参与媒体丰富的课程补充中的活动如何改善低收入儿童的学习。 该项目使用混合方法（民族志观察和访谈以及HLM分析）来回答研究问题。 该项目解决了开发高质量幼儿数学课程的迫切需要，特别是针对低收入学生的课程。该项目涉及两个重要内容领域。 无论是内容还是授课方式，都对课程的开发和研究做出了重大贡献。这个项目可以提供有关如何有效地利用技术来改善学生学习的急需的见解。

In this full research and development project, a team of learning scientists and media researchers at Education Development Center and SRI International will collaborate with educational media producers at WGBH to develop, test, and refine a curriculum supplement (a hands-on technology) that (1) promotes childrens' understanding of number (counting, comparing, and ordering) and fair sharing (equipartitioning); (2) uses interactive media on an emerging handheld platform (touch screen tablets), integrating new multi-touch activities with existing hands-on activities; (3) enhances opportunities for learning with interactive media through shared use with adult guides and peers; and (4) provides professional and technical support materials for preschool educators. The project investigates if and how engagement with activities in a media-rich curriculum supplement improves low-income young childrens' early learning of number and equipartitioning. The project builds on sound research about learning trajectories to develop materials for fostering young childrens' learning. In addition, this project will generate new research findings about how engagement with activities in a media-rich curriculum supplement can improve low-income childrens' learning. The project uses use mixed methods (ethnographic observations and interviews and HLM analyses) to answer the research questions. This project addresses a critical need to develop quality early childhood mathematics curriculum, particularly that aimed at low-income students. This project involves two important content areas. Both the content and the mode of delivery make major contributions to curriculum development and research. This project can provide much needed insights about how to effectively use technology for improving student learning.
