the Videotape Classroom Study The study sample included 231 eighth-grade mathematics classrooms: 100 in Germany, 50 in Japan, and 81 in the United States. The sample was designed to be representative of eighth-grade classrooms in the three countries, although some deviations arose in the implementation of the sample. The findings can be considered representative of the instruction received by eighth grade students in each country. One lesson was videotaped in each classroom at some point during the school year. Tapes were encoded and stored digitally on CD-ROM, and were accessed and analyzed using multimedia database software developed especially for this project. All lessons were transcribed, and then analyzed on a number of dimensions by teams of coders who were native speakers of the three languages. Analyses focused on the content and organization of the lessons, as well as on the instructional practices used by teachers during the lessons. |
