Educational Software Components of Tomorrow: A Testbed for Suitable Development of Reusable, Interoperable Object for Middle School Mathematics Reform

小行星9804930 大多数NSF资助的教育技术项目都为特定的主题目标创建了一个单一的软件程序。 这些项目为在科学和数学教育中适当使用技术提供了宝贵的知识基础。 然而，它们通常还没有解决扩大规模或可持续性问题。 因此，太少的产品，这项研究是广泛提供的软件市场或已与新的课程，以满足系统的改革的挑战。 在这个项目中，我们关注的不是单一的软件需求，而是更广泛的问题，即软件创新如何积累、整合和扩展，以满足K-12数学和科学教育系统改革的需求。 未来教育软件组件（ESCOT）项目通过利用新兴的强大力量（交互式媒体，网络社区和组件软件技术）的融合来解决这个问题。 总之，这些力量有可能重塑教育软件开发的基础设施，产生一个新的网络经济，旨在满足国家对教育软件的需求，具有更高的效率，创新和增长的能力，以及对质量的竞争动力。 我们的假设是，这些力量的汇合可以为K-12系统性改革软件的可持续发展提供基础设施。 ESCOT将追求四个研究目标：（a）形成一个实验测试平台-一个由教师、研究人员和开发人员组成的分布式网络，使用共享的软件资源来调查这一假设;（B）在基于标准的改革工作的技术需求和可行的软件模块之间建立映射;（c）确定使用互联网促进分布式、自组织一体化团队的方法;以及（d）分析用于实现教育软件组件之间的互操作性的机制和设计模式。 ESCOT测试平台支持最初的NSF课程开发战略，开始以现有的基于标准的中学数学课程和实施工作为基础，旨在构建知识和范例，为K-12数学和科学的政策和实践提供更广泛的信息。 在形成和研究ESCOT测试平台时，SRI国际将与斯沃斯莫尔学院、马萨诸塞大学达特茅斯分校、科罗拉多大学博尔德分校合作，并与五个NSF支持的中学数学课程项目和密苏里州大学的附属实施中心协调。 ***

9804930 Pea Most NSF-funded educational technology projects have created a single software program for a specific subject matter goal. These projects have yielded a valuable base of knowledge about the appropriate use of technology in science and math education. Yet they typically do not already address scale-up or sustainability. Thus, too few products of this research are widely available in the software marketplace or have been integrated with new curricula to meet the challenges of systemic reform. In this project we focus not on a single software need but on the broader problem of how software innovations can accumulate, integrate, and scale up to meet the needs of systemic reform of K-12 mathematics and science education. The Educational Software Components of Tomorrow (ESCOT) project addresses this problem by leveraging an emerging convergence of powerful forces: interactive media, networked communities, and component software technologies. Together, these forces have the potential to reshape the infrastructure for educational software development, resulting in a new network economy that will be designed to meet national needs for educational software with greater efficiency, capacity for innovation and growth, and competitive drive toward quality. Our hypothesis is that the confluence of these forces could provide an infrastructure for sustainable development of software for K-12 systemic reform. ESCOT will pursue four research objectives: (a) form an experimental testbed-a distributed network of teachers, researchers, and developers using a shared collection of software resources-to investigate this hypothesis; (b) develop a mapping between the technology needs of standards-based reform efforts and feasible software modules; (c) identify ways of using the Internet to catalyze distributed, self-organizing integration teams; and (d) analyze mechanisms and design patterns for achieving interoperability among educational software components. Paralleling the initial NSF cur riculum development strategy, the ESCOT testbed begin with existing standards-based middle school mathematics curricula and implementation efforts, with the aim of building knowledge and exemplars that inform policy and practice more broadly across K-12 mathematics and science. In forming and studying the ESCOT testbed, SRI International will team with Swarthmore College, the University of Massachusetts-Dartmouth, the University of Colorado-Boulder and coordinate with the five NSF-supported middle school mathematics curriculum projects and affiliated implementation center at the University of Missouri. ***
