th the thousands of educational apps vying for the attention of busy teachers, it can be hard to sift for the gold. Michelle Luhtala, a savvy librarian from New Canaan High School in Connecticut has crowd-sourced the best, most extensive list of apps voted on by educators around the country. “I wanted to make sure we had some flexibility because there’s no one app that’s better than all the others,” Luhtala said. Some apps are best for younger students, others are more complicated, better suited for high school students. Many apps do one thing really well, but aren’t great at everything. Still others are bought, redesigned or just disappear — so it’s always good to know about an array of tools to suit the need at hand.
