As kids across the country are getting ready to go back to school, one page you may want to bookmark is a free web site called ASSISTments. The site offers students math homework hints that have been crowdsourced from teachers using that particular math curriculum. So far research has shown students answer problems correctly in 58% of cases, compared with 54% for those without access to the hints, according to a forthcoming study. Neil Heffernan, a professor at Worcester Polytechnic Institute in Massachusetts who established the program, says that more importantly is to determine whether the hints help students complete more math homework, rather than giving up when they get stuck.
