Science, Technology, Engineering and Mathematics (STEM) education has continued to attract attention and sizeable funding worldwide. Given the important role that teachers play in the provision of quality STEM education, this chapter provides an overall landscape of STEM teacher education in China and Hong Kong. The chapter presents an overview of policies, practices and research in teacher education and professional development in STEM education that have been and continue to be implemented in Mainland China and Hong Kong for the purpose of supporting teachers to effectively implement STEM education. Literature from a range of sources, including discussion and research papers, government reports and policy papers with respect to STEM teacher education in Mainland China and Hong Kong have been selected. The analysis of policies and practices is useful to provide a review of what has been done and to inform new directions for teacher education for STEM education.

This research linked 47 Hong Kong and 35 Canadian teacher candidates in a new participatory culture project within the theoretical framework of new media literacies. This paper reports the qualitative data with quantitative descriptions of participants' social interactivity within the cross-border communities of practice. Besides the constraints of the designated online forum, findings relate that participants' engagement in the new participatory culture contributed to their knowledge- and awareness-building of harnessing online participation, new media technologies, and cultural/linguistic diversity in education. The paper concludes with implications of cultivating communities of practice buttressed by new media literacies for teacher professional development.
