Situating teacher learning in the intersection of the two different school systems, curriculums, and cultures of mathematics learning and teaching in both nations, this volume offers teachers a unique and much-needed perspective on how practices between countries become more and more likely shaped by each other in the emerging global society. Born out of a comparative study project sponsored by the SSHRC, this volume compiles five years' worth of findings from reciprocal partnerships between researchers, teachers, school administrators, and students from both nations. Through the process of reciprocal learning and narrative inquiry, the research described in these chapters illuminates the unknown and shares newly-created mathematics education knowledge. 410 0$aIntercultural Reciprocal Learning in Chinese and Western Education,$x2946-4188 606 $aMathematics$xStudy and teaching  606 $aInternational education 606 $aComparative education 606 $aTeachers$xTraining of 606 $aEducation$xCurricula 606 $aEducation 606 $aMathematics Education 606 $aInternational and Comparative Education 606 $aTeaching and Teacher Education 606 $aCurriculum Studies 606 $aEducation 615 0$aMathematics$xStudy and teaching . 615 0$aInternational education. 615 0$aComparative education. 615 0$aTeachers$xTraining of. 615 0$aEducation$xCurricula. 615 0$aEducation. 615 14$aMathematics Education. 615 24$aInternational and Comparative Education. 615 24$aTeaching and Teacher Education. 615 24$aCurriculum Studies. 615 24$aEducation. 676 $a510.71051 702 $aZhu$b Sijia Cynthia 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910468231203321 996 $aReciprocal learning for cross-cultural mathematics education$92113484 997 $aUNINA
