I am the learning design lead at Play-i (play-i.com). We build robots to teach kids ages 5+ how to program. I am a cognitive and developmental psychologist. I did my PhD in how early language input from parents affect kids' readiness to learn number and math concepts before a postdoc on applying cognitive science to middle school science education and another postdoc on how 2D and 3D block building affects geometric and spatial cognition and later math performance. I joined my first educational gaming startup in 2011. It imploded within 6 months, but that's another story ;)
