In a series of experiments carried out more than a decade ago, Arthur Glenberg of Arizona State University "found that children’s reading comprehension improved when they acted out a written text, using a set of representational toys (a miniature barn and horse, for example, accompanied a story about a farm). Glenberg then demonstrated that the same procedure could work on a digital platform: In a 2011 experiment, he showed that having first- and second-grade students manipulate images of toys on a computer screen after reading a story benefits their comprehension as much as physical manipulation of the toys."
Games are also an important learning tool for students and not just for the young ones either; we use games all the time at both the undergraduate and graduate levels. Never make the mistake of thinking that what you're doing is too childish for the students in front of you; they'll love it. Here's a great game described in the article:
"Mina Johnson Glenberg (who is married to Arthur Glenberg and also works at Arizona State, as director of the university’s Embodied Games for Learning lab) is taking the embodied approach even further, designing educational games that engage learners’ entire bodies.
