Last year I bought my first math app ever, Motion Math, and reviewed it in a blog entry. A friend just sent me an article, "Proof in Study: Math App Inproves Test Scores (And Engagement)", talking about an independent study in which Motion Math "showed that fifth graders' fractions test scores improved an average of over 15% after playing Motion Math for 20 minutes daily over a five-day period, a significant increase compared to the control group." It also showed an increase in their overall liking of fractions. Although I think my son does show a natural affinity toward fractions, we seem to be cruising through our fraction curriculum at breakneck speed... Maybe his exposure to Motion Math helped?
I find this all very interesting. I wonder where apps in education are headed...? Do you use math apps in the classroom or with your homeschool student?
(And I don't work for Motion Math or get any kickbacks, btw. I even had to plunk down the .99 for my own game! :)
