Science Analysis for TIMSS-R Videotape Classroom Study

作为TIMSS-R视频研究的一部分，在五个国家--捷克共和国、荷兰、日本、澳大利亚和美国--收集了具有全国代表性的八年级科学课程的录像带样本。其中前三个国家是TIMSS科学成就测试中表现最好的国家之一。数据的收集已经得到了NCES的资助。我们正在寻求资金来准备、编码、分析和解释这些数据，以便提供第一个关于科学教学的跨国描述。我们还建议，在今后的研究和改进工作中，以最大限度地利用数据的方式开展这些进程。

As part of the TIMSS-R video study, nationally representative videotape samples of eighth-grade science lessons are being collected in five countries--the Czech Republic, the Netherlands, Japan, Australia, and the United States. The first three of these were among the highest performing countries on the TIMSS science achievement tests. Collection of the data is already funded by NCES. We are seeking funding to prepare, code, analyze, and interpret the data in order to provide the first cross-national descriptions of science teaching. We further propose to carry out these processes in a way that maximizes usability of the data in future research and improvement efforts.
