sentences:  They gave assessments to the children, their parents, and their teachers in order to determine the children's levels of academic achievement, and the results showed that students who had taken part in a structured after-school program were more likely to have better grades and to perform higher in math and reading tests than those who had not taken part in an after-school program.Similarly, a 2010 study by Durlak, Weissberg, and Pachan showed that both children and adolescents experienced significant academic gains by taking part in afterschool programs.Several other studies (e.g., Morrison, Storino, Robertson, Weissglass, & Dondero, 2000; Tucker et al., 1995) have found that after-school academic tutoring or homework assistance may not result in an improvement in academic performance, but, rather, prevent a decline in performance that is evidenced by many at-risk youth.
