Expanding the Accessibility of NSDL for Mobile Learning

该项目通过建立一个原型服务并评估其对K-12和高等教育中非正式和结构化移动学习的教育影响，重点关注9-14年级(高中和低年级本科生)以及PDA、手机和音乐/视频播放器的使用，解决了与使用小型无线计算设备和NSDL相关的学习者体验的关键用户需求。由于目标是提高不同人群对NSDL的可及性，评估考点包括奥克兰/伯克利的市中心学校和外展项目。该项目(1)为利用移动设备的STEM教育数字资源提供元数据建议；(2)实施和测试用户概况、个性化特征和本地环境的各个方面，以支持小型移动设备与NSDL集合的接口；(3)为小窗口形式的因素和本地环境的各个方面实施个性化的工作空间、搜索和元数据浏览器；(4)在9-12年级和低级大学生的结构化和非正式移动学习活动中测试原型；(5)利用NSDL内容开发符合教学要求的移动学习使用场景；以及(6)根据我们的原型测试和评估，为NSDL社区提供移动设备服务建议。

The project addresses critical user needs around learner experiences related to the use of small wireless computing devices and the NSDL by building a prototype service and evaluating its educational impact on informal and structured mobile learning in both K-12 and Higher Education, with a focus on grades 9-14 (high school and lower division undergraduate) and use of PDAs, cell phones and music/video players. As the goal is to improve accessibility of the NSDL to diverse populations, evaluation test sites include inner city schools and outreach programs in Oakland/Berkeley. The project is (1) providing metadata recommendations for STEM education digital resources that utilize mobile devices; (2) implementing and testing user profile, personalization features and aspects of the local environment to support small mobile devices to interface with NSDL collections; (3) implementing personalized workspaces, search and metadata browser for small window form factors and aspects of the local environment; (4) testing prototypes in both structured and informal mobile learning activities in grades 9-12 and with lower division university students; (5) developing pedagogically-sound use scenarios of mobile learning with NSDL content; and (6) providing recommendations for mobile device services for the NSDL community that emerge from our prototype testing and evaluation.
