Understanding Classroom Interactions Among Diverse, Connected Classroom Technologies

该项目与德克萨斯仪器、Palm和诺基亚这三家主要合作伙伴一起，研究配备交互式计算媒体的廉价手持设备网络对日常课堂教学和学习的影响。了解这种大规模课堂连接的影响非常重要，以便为以下方面的迭代改进提供信息：(1)支持学习的技术和课堂实践；(2)教师发展和支持结构的设计。PI及其同事正在与8-12年级普通教室的教师合作，这些教室配备了学校标准的图形计算器和相互之间以及与教师工作站无线联网的新设备。(1)评估：定期、有原则地诊断学生对精心设计的探针和问题的反应，并将其提交给教师进行分析和采取行动。(2)学习：新的学生活动结构包括(a)师生和学生之间的挑战，以及(b)学生对共享和公开展示的结构的贡献。(3)教学：教师课堂管理支持，分发和收集学生作业，查看和注释学生屏幕，管理连接课堂中的信息流。

Together with three major corporate partners, Texas Instruments, Palm, and Nokia, this project is investigating the impact on everyday classroom teaching and learning of a network of inexpensive hand-held devices equipped with interactive computational media. The effects of this massive classroom connectivity are important to understand in order to inform iterative improvement of i) technologies and classroom practices that support learning and ii) the design of teacher development and support structures. The PI and colleagues are working with teachers in ordinary grade 8-12 classrooms equipped with school-standard graphing calculators and newer devices wirelessly networked to each other and to a teacher's workstation. Three areas of impact are under exploration: (1) Assessment: regular, principled diagnoses of students' responses to carefully designed probes and problems submitted to the teacher for analysis and action. (2) Learning: new student activity structures involving (a) teacher-student and student-student challenges, and (b) student contributions to shared and publicly displayed constructs. (3) Teaching: teacher classroom management support for distributing and collecting student work, viewing and annotating student screens, and managing the flow of information in the connected classroom.
