The goal of this series is to use teachers' accounts of classroom
inquiry to make public and explicit the processes of doing research in
classrooms. Teaching is a complex, multi-faceted task, and this
complexity often is not captured in research articles. Our goal is to
illuminate this complexity. Research that is done in classrooms by and
with teachers is necessarily messy, and our stance is that the ways in
which this is so should be articulated, not hidden. Through the chapters
in this volume we learn about the questions that capture the attention
of teachers, the methodologies they use to gather data, and the ways in
which they make sense of what they find. Some of the research findings
could be considered preliminary, others confirmatory, and some may be
groundbreaking. In all cases, they provide fodder for further thinking
and discussion about critical aspects of mathematics education.
