If you could peer into a classroom in a foreign country, what would you see? If you could see multiple lessons from that country, what patterns would emerge?

However, the authors of this article, as part of the Third International Mathematics and Science Study (TIMSS) 1999 Video Study, were able to participate in the endeavor described above -- albeit via video, rather than in personIf you could peer into a classroom in a foreign country, what would you see?
