A Network-Based Interactive Distance Education Program in Mathematics For Students And For Teacher Enhancement in Rural And Inner-City

佩雷西尼9353689这项建议是对国家科学基金会早先的一项建议(国家科学基金会-ID-9353689)的应邀修订，该建议“利用计算机网络为农村和市中心高中的教师提供交互式大学微积分教学和在职技术培训”，减少了预算和活动范围。在过去的四年里，一个连接伊利诺伊大学和大约25所农村和市中心高中的基于现代的网络和远程互动教学策略已经发展起来，能够以教育上合理和成本效益高的方式向这些学校提供大学学分、基于电子文本的微积分课程《微积分与数学》。当局现正作出安排，由一九九六至九七学年开始，继续采用这种不依赖补助金的授课模式。直接教学成本，包括网络成本，将由参与的学区和学生分担，而行政成本将由大学承担。这项建议寻求拨款，以扩展和加强这一现有的网络试验平台：1)实施和评估两种新的联网模式，这两种模式基于ISDN或T-1线路连接，不仅能够加强互动课程的教授，而且能够向参与学校提供互联网教学资源；2)设计、实施和评估教师增强活动(现场和电子)，以发展一个校本人员社区，其成员有能力在其学校以技术为基础的数学和科学教育方面提供领导；3)在我们的网络和其他正在向高中提供数学和科学资源的网络之间建立适当的联系，包括由NSF资助的芝加哥城市系统倡议。该项目的评估计划将是形成性和终结性的，并将体现：1)新模式在当前模式下的授课表现；2)教师强化活动的有效性；3)项目所导致的参与学校的教学环境的变化。最终目标将是开发一种可持续的(即不依赖赠款)、具有成本效益的互联网网络模式，将大学与参与的高中联系起来，以便提供课程、加强教师能力活动和获取教学资源。***

Peressini 9353689 This proposal is an invited revision of an earlier NSF proposal "Using computer networks to provide interactive university calculus instruction and in-service technology training for teachers in rural and inner-city high schools" (NSF-ID-9353689) with a reduced budget and scope of activities. During the past four years, a modem-based network connecting the University of Illinois to approximately twenty-five rural and inner-city high schools and a distance interactive instructional strategy have evolved that are capable of delivering a college- credit, electronic text-based calculus course, Calculus & Mathematics, to these schools in an educationally sound and cost effective manner. Arrangements are now being made to sustain this model for course delivery independent of grant funds beginning with the 1996-97 school year. The direct instructional costs, including network costs, will be shared by the participating school districts and students, while the administrative cost will be borne by the University. This proposal seeks funding to expand and enhance this existing network testbed by: 1) implementing and evaluating two new networking models that are based on ISDN or T-1 line connections and that are not only capable of enhanced interactive course delivery, but also the delivery of Internet instructional resources to the participating schools; 2) designing, implementing and evaluating teacher enhancement activities (on-site and electronic) to develop a community of school-based personnel whose members are equipped to provide leadership in technology-based mathematics and science education in their schools; 3) establishing appropriate linkages between our network and other networks here and elsewhere that are delivering mathematics and science resources to high schools including the NSF-funded Urban Systemic Initiative in Chicago. The evaluation program for the project will be both formative and summative, and will ad dress: 1) course delivery performance of the new models with the current model; 2) effectiveness of the teacher enhancement activities; 3) changes in the instructional environment in the participating schomls resulting from the project. The ultimate objective will be to develop a sustainable (i.e. grant-independent), cost effective Internet-based network model linking the University and the participating high schools for the purposes of course delivery, teacher enhancement activities, and instructional resource access. ***
