      abstract = {A study of 1,364 students in 74 senior high school classes  in which geometry proof was taught found equal ability  among males and females to write geometry proofs. These  results held as well for select high-achieving subsamples.  These findings and data from other recent studies suggest  that girls and boys perform equally well even on complex  mathematical tasks if both in-class and out-of-class  exposure to the tasks is equal.},
