Science Analysis for TIMSS-R Videotape Classroom Study

作为TIMSS-R录像研究的一部分，正在捷克共和国、荷兰、日本、澳大利亚和美国五个国家收集具有全国代表性的八年级科学课录像带样本。 其中前三个国家在TIMSS科学成就测试中表现最好。 数据收集工作已经得到了国家统计和普查局的资助。 我们正在寻求资金来准备，编码，分析和解释数据，以提供科学教学的第一个跨国描述。 我们进一步建议在未来的研究和改进工作中最大限度地提高数据的可用性。

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.
