Xiong Wang has recently defended her doctoral dissertation at the University of Alberta. Before pursuing her doctoral study at the University of Alberta, she had been a mathematics teacher and an associate professor in China and a research fellow in Singapore. Her research interests focus on teachers’ professional learning, online learning and assessment in mathematics education. Supervised by Dr. Elaine Simmt, her dissertation aims to examine the nature of the relatively new phenomena of mathematics teacher professional learning through social networks (e.g., Twitter and blogs) based on complexity thinking.
