I'm starting to focus on studies about the involvement of interactive games for preschool/primary students in the building of pre-literacy and pre-math skills, given some mounting evidence that this is an underutilized area in education.
The latest: THE Journal reports on a study from the Educational Development Center that suggests preschool students learn pre-literacy skills better in an environment with repeated exposure to interactive games. The specific skills were letter recognition, letter naming, letter sounds, and understanding story concepts.
Take this study with a grain of salt. I'm not convinced of the methodology, as the comparison group was a science curriculum, not a literacy curriculum, and it was commissioned by PBS, which while I admire their overall work in helping students learn, they still have a vested interest in seeing a positive correlation.
Best news though is that it is leading to further studies. Given available technology that is more accessible to young students than ever before, this will lead to more purposeful game development for that age, with a better tie-in to the Iowa Core.
