TeachEngineering: Expanding and Sustaining Curriculum Access for K-12 Teachers

科罗拉多大学博尔德分校的TeachEngineering(TE)数字图书馆在K-12工程教育界享有声誉，是免费的、经过课堂测试的、基于标准的课程的高质量教师资源。作为46个工程授权者原创K-12工程课程的传播者，该藏书每年有230万用户访问，年增长率为50%。TeachEngineering课程和活动及其周围的互动社区论坛支持教师在课堂上达到新的基于工程的标准。吸引更多、更多样化的学生学习工程学，为未来的职业和满意的生活奠定基础，培养年轻人的雄心壮志，同时为改善和维持国家的经济未来奠定基础。拟议的战略改进和以用户为中心的研究确保了TeachEngineering的持续相关性和可持续性。这项为期三年的计划的目标包括使用户体验具有互动性和社区基础，扩大集合规模和使用，使课程与不断发展的K-12 STEM标准保持一致，实现后端架构的现代化，以实现可持续性和响应性，以及评估课堂影响。活动和方法包括通过设计和/或实施基于社会、社区和众包的特点，大大扩大K-12教师群体的直接参与。这一用户参与产生的丰富的新信息源将有助于显著改善用户体验，并有助于为集合编制索引，以便更好地自动搜索、推荐和标准匹配设施。将采用的方法包括与NAE的LinkEngineering社区合作，创建一个更完整的集合元模型，实施模型-视图-控制器框架，以及对教师如何在课堂上使用TE进行定量和定性研究。

The TeachEngineering (TE) digital library, at the University of Colorado at Boulder, has attained a reputation in the K-12 engineering education community as a high-quality teacher resource of free, classroom-tested, standards-based lessons. As the disseminator of original K-12 engineering curricula from 46 engineering grantees, the collection is accessed by 2.3M users annually, realizing 50% annual growth. The TeachEngineering lessons and activities and the interactive community forums around them support teachers in meeting new engineering-based standards in their classrooms. Attracting more, and more diverse, students to engineering for future occupations and satisfying lives cultivates ambitions in the young while setting the stage for improving and sustaining the nation's economic future. The proposed strategic improvements and user-centered research ensure TeachEngineering's ongoing relevance and sustainability.The goals of this three-year initiative include making the user experience interactive and community based, expanding collection size and usage, keeping curricula aligned with evolving K-12 STEM standards, modernizing the backend architecture for sustainability and responsiveness, and assessing classroom impact. Activities and approaches include significant expansion of direct involvement of the K-12 teacher community through the design and/or implementation of social, community based and crowdsourced features. The rich new source of information generated by this user involvement will serve to significantly improve the user experience and help index the collection for better and automated search, recommender and standards alignment facilities. Methods to be employed include partnering with the NAE's LinkEngineering community, creation of a far more integrated metamodel of the collection, implementing a model-view-controller framework, and conducting quantitative and qualitative studies on how teachers use TE in the classroom.
