Based on students' preferences, they were assigned to use standing desks during the experimental study. According to the authors, quoted by Science Daily:
"Test results indicated that continued use of standing desks was associated with significant improvements in executive function and working memory capabilities," Mehta said. "Changes in corresponding brain activation patterns were also observed."
Wow! That almost deserves a standing ovation! On the blog in the past I've reported on a number of studies that demonstrate the cognitive benefits of exercise on learning and memory and the corresponding enhancement of attitude and motivation that getting students up and moving around produces.
Even if your school is not set up with stand up desks, you can at least get students on their feet occasionally, not just for pronunciation but almost any in-class activity (as I'm sure many of you do already.) One of my all time favorites is the "Talkaboutwalkabout!" in fact.
