While women's participation in math and physical science continues to lag to some degree behind that of men, the disparity is much greater in engineering and computer science. Though boys may outperform girls at the highest levels on math and science standardized tests, girls tend to get better course grades in math and science than boys do.…

The out-of-school time (OST) domain offers a promising resource for enriching young people's experience of science, technology, and engineering. Belief is widespread that OST programs are ideal locations in which to learn science and that youth participation may increase access to science for underrepresented groups, such as girls or minorities,…
