We have all at one point or another learned some variation of a mathematical formula involving trains and their timetables. For example: if a train leaves Boston for New York at 7am and travels at 60mph, will it beat a train leaving Providence at 6am traveling 45mph? The idea behind this kind of "story" problem is to engage a student with a real-world example to which they can relate. The thinking follows that that engagement will solidify the mathematical concept. It's one of those conceits that has hung around for seemingly as long as math has been taught. And it may very well be completely wrong.

We first became acquainted with Mrs. Daftari's fifth-grade class earlier this year when they rose to a challenge printed in PopSci by submitting their essays for how they'd change the world. Most recently, they sent us these video responses to our 5-Minutes Projects series. In the second, McKenna Mooney and Madison Wilson replicate Megan Miller's DIY non-Newtonian fluid (otherwise known as slime). And in the first, Kacie Moore and Olivia Johnson present a project of their own: the sound catcher.

If we have learned anything about education in recent years, it’s that the one-size-fits-all mentality of the basal reader just does not work. People learn differently; sexes learn differently. But the research has only gone so far in exploring from where these differences originate. Previously, studies focused only on cognition or brain function.
