The award honors free, user-friendly websites that encourage educational creativity, active participation, innovation and collaboration. Science NetLinks was recognized in the award's content resources category.
Donna Baratta, chair of the AASL committee that chose this year's winners, said the wining sites "will support inquiry and project based learning while immersing students in learning."
"We are honored to have been recognized by AASL and proud to develop innovative teaching resources that engage the 21st-century learner, and encourage the budding scientist," said Suzanne Thurston, the AAAS project director for Science NetLinks.
Content from Science NetLinks, which debuted in 1997, is also featured on the Verizon Foundation's Thinkfinity.org  site, which provides free, Internet-based educational resources and an online community for educators. Science NetLinks receives more than 250,000 visits each month.
The site was revamped in 2011 to provide new options for exploring its hundreds of lesson plans, online tools, special resource collections and after-school activities for K-12 teachers, students and families. Science NetLinks also features two AAAS news feeds: Science for Kids , which offers student-friendly stories based on reports from the journal Science, and ScienceNOW , the journal's daily online news section.
