Last year, Edudemic published a list of the most essential and popular educational tools used in modern classrooms across the globe. While many of 2013′s contenders retain top spots for 2014, there are a few new and noteworthy tools that made it onto this year’s list, and some of last year’s mentions have shifted in the rankings. We highly recommend taking a look at these “battle-tested” teaching tools; some of them may be a perfect fit for your modern classroom.
