Math anxiety causes trouble for students as early as first grade

William Harms:

Many high-achieving students experience math anxiety at a young age — a problem that can follow them throughout their lives, new research at the University of Chicago shows.
In a study of first- and second-graders, Sian Beilock, professor in psychology, found that students report worry and fear about doing math as early as first grade. Most surprisingly math anxiety harmed the highest-achieving students, who typically have the most working memory, Beilock and her colleagues found.
