In the age of educational games and the Big Data they generate, we have more information than ever about what 
students  are  doing  and  how  they  are  thinking.  But  the  sheer  volume  of  data  available  can  overwhelm  traditional  
qualitative and quantitative research methods. Quantitative Ethnography is a set of research methods that combine 
ethnographic techniques with statistical tools—a way to go beyond looking for arbitrary patterns begin generating 
meaningful insights about learning at scale. This talk provides an overview of the science of Quantitative Ethnography 
and a preview of two key tools that researchers can use to assess complex thinking.
