A century ago a group of educators led an effort to transform American Jewish education to enable it to operate successfully in the 20th century. Today, with American Jews living under very different conditions, a similar effort is needed to reinvent Jewish education for the 21st century. Changes and new initiatives already taking place on the educational landscape point the way toward a set of paradigm shifts that will make Jewish education more learner-centered, relationship-infused, and life-relevant. These changes at the level of educational practice need to be accompanied by a redesign of the educational system itself to make it better able to accommodate learners as "prosumers," helping to create their own educational experiences, and to guide them on lifelong learning journeys. By maximizing the impact of ongoing innovations, by employing "design thinking," and by forging stronger networks and collective impact initiatives across domains and settings, the Jewish educational system can be reinvented to meet the needs and aspirations of 21st century Jewish learners.
