Video games could dramatically streamline education research

September 19, 2014 9:12 am | by C. Brandon Chapman, Washington State Univ. | News | Comments

Washington State Univ. professor Rich Lamb has figured out a dramatically easier and more cost-effective way to do research on science curriculum in the classroom, and it could include playing video games. Called “computational modeling,” it involves a computer “learning” student behavior and then “thinking” as students would. Lamb, who teaches science education, says the process could revolutionize the way educational research is done.
