The phrase “mind the gap” has become synonymous with the London Tube. In an underground system with platforms dating back to the 19th Century, it stands to reason not all trains line up perfectly with every platform. As the doors open, passengers are warned to “mind the gap”.
It struck me this phrase also describes the experience encountered by educators when attempting to apply contemporary theory, policy and research to their specific educational contexts. “Trains” of all shapes and sizes seem to pull up regularly at your particular platform without perfect alignment. So mind the gap and make suitable adjustments before adopting new initiatives and selecting specific theories for your context.
