Book by Brown, Roediger, and McDaniel, Make it Stick: the science of successful learning, The Belknap Press of Harvard University Press: London, England, 2014.
This book describes how to use quizzing, distributed practice, interleaving to increase student learning (or rather, to "interrupt forgetting"). Highly readable, both for teachers and for students.
