The presenter will provide an up-to-date overview of Hong Kong's diverse, multidimensional literature. She will focus on the lesson and learning study definitions, mapping of the process(es) and aspects that take priority. In light of this, she will offer a characterization of the research. Discussion will then focus on the implications of the research in terms of ultimate purposes and values, and emerging research trends and future directions. Not only will this be a discussion of the Hong Kong learning and lesson study research literature, but it will also provide a forum to nurture global dialogue.
