Measures of Effective Teaching Longitudinal Database

The Measures of Effective Teaching (MET) project is the largest study of classroom teaching ever conducted in the United States. The University of Michigan compiled the MET data and video files into a rich research collection called the MET Longitudinal Database. Approved researchers can access the restricted MET quantitative and video data using secure online technical systems. The MET Longitudinal Database consists of a Web-based application for searching the collection and viewing the videos with accompanying metadata, and a Virtual Data Enclave that provides secure remote access to the quantitative data and documentation files.

有效教学度量（MET）项目是美国迄今为止进行的最大规模课堂教学研究。密歇根大学将MET数据及视频文件汇编成名为MET纵向数据库的丰富研究资料库。经批准的研究人员可通过安全的在线技术系统访问受限制的MET定量数据和视频数据。MET纵向数据库包含一个基于网络的搜索应用，用于检索资料库并查看附有元数据的视频，以及一个提供对定量数据和文档文件安全远程访问的虚拟数据堡垒。
