Purpose: This study aimed to explore how a group of Chinese primary mathematics teachers learned through conducting an online cross-cultural lesson study between China and Australia. Design/methodology/approach: An expansive learning theory was adopted to examine teachers' learning through collective activities across different activity systems.…

The major premise of this project is that teachers learn from the act of teaching a lesson. Rather than asking "What must a teacher already know in order to practice effectively?", this project asks "What might a teacher learn through their activities in the classroom and how might this learning be optimised?" In this project,…

This study examines how mathematics teaching research specialists mentor practicing teachers during post-lesson debriefs of a lesson study in China. Based on a systematic, fine-grained analysis of 107 h of videotaped mentoring meetings of 20 groups of teachers and teaching research specialists from different elementary schools, this study reveals…

Reports that teaching elementary mathematics requires a much deeper mathematical knowledge than most experts have believed and that teachers must receive the training, textbooks, time, and support needed to develop this knowledge. Notes that U.S. mathematics teachers' knowledge is not nearly as robust as that of Chinese mathematics teachers, and…

Chinese researchers investigated how mathematics teachers in two elementary schools in northeast China adapted the national curriculum. One school was in a very poor, mountainous area, and the other school was in a very large city. Both used the national curriculum and the same set of teaching materials. Researchers used ethnographic methods to…
