By Wendy S. Bray elling children that they can learn from their mistakes is common practice. Yet research indicates that many teachers in the United States limit public attention to errors during math- ematics lessons (Bray 2011; Santagata 2005). Some believe that drawing attention to errors publicly may embarrass error m
