Knowledge Networks in Focused Teaching and Learning Communities: Promoting Successfull, Sustainable and Scaleable Educational Improvement

刘易斯9811907 全国各地的学院和大学都对招收反映全国人口的种族和语言多样化的学生团体越来越困难感到遗憾。 加州的209号提案、德克萨斯州的霍普伍德决定以及其他州（密歇根州和华盛顿州）日益增长的立法趋势进一步集中讨论了谁能够上大学。 随着高中文凭市场价值的下降和劳动力日益多样化，其中三分之一是少数群体成员（SCANS，报告，1992年），必须重视所有族裔群体的大学教育。 在过去的一年里，兰德公司和AVID公司一直在合作开发一种名为AVIDnet的新型网络资源。 他们已经进行了调查，焦点小组和初步设计的系统，将使用技术提供一个基础设施的支持，扩大AVID计划。 这一努力代表了其同类的第一次试验，以证明如何丰富，网络互动媒体可以直接服务于公立学校的教学和学习社区的需要在初中和高中高年级水平。 本规划补助金和未来大规模研究中提出的设计、实施和评估的目的是从AVIDnet开发经验中实时提取宝贵的经验教训。 预计研究结果不仅将为今后使用AVIDnet提供信息，而且还将支持其他方面通过有效使用这些新媒体加强教学的努力。

9811907 Lewis College and universities nationwide lament the increasing difficulty of enrolling ethnically and linguistically diverse student bodies that reflect the population of the nation. Proposition 209 in California, the Hopwood Decision in Texas, and the growing trend toward such legislation in other states (proposed in Michigan and Washington) have further focused the discussion of who is able to attend college. With the decreasing market value of a high school diploma and an increasingly diverse workforce, one third of whom are members of minority groups (SCANS, Report, 1992), a premium must be placed on a college education for all ethnic groups. For the past year, RAND and AVID had been collaborating on a new model of networked resources called AVIDnet. They have already produced surveys, focus groups, and preliminary designs of systems that would use technology to provide an infrastructure of support for expanding AVID Programs. This effort represents one of the first trials of its kind to demonstrate how rich, networked interactive media can directly be made to serve the needs of the public-school teaching and learning community at middle and senior high grade levels. The purpose of the design, implementation, and evaluation proposed in this Planning Grant and in future larger-scale research, is to extract valuable lessons in real-time from the AVIDnet development experience. Results of the research would be expected not only to inform future uses of AVIDnet but also to support efforts undertaken by others to enhance teaching and learning through effective use of these new media.
