Rongjin Huang examines teachers' knowledge of algebra for teaching, with
a particular focus on teaching the concept of function and quadratic
relations in China and the United States. 376 Chinese and 115 U.S.A.
prospective middle and high school mathematics teachers participated in
this survey. Based on an extensive quantitative and qualitative data
analysis the author comes to the following conclusions: The Chinese
participants demonstrate a stronger knowledge of algebra for teaching
and their structure of knowledge of algebra for teaching is much more
interconnected. They show flexibility in choosing appropriate
perspectives of the function concept and in selecting multiple
representations. Finally, the number of college mathematics and
mathematics education courses taken impacts the teachers' knowledge of
algebra for teaching.
