Keynote speaker Dr. Marina Umaschi Bers is a professor and chair at the Eliot-Pearson Department of Child Study and Human Development and an adjunct professor in the Computer Science Department at Tufts University, where she heads the interdisciplinary Developmental Technologies (DevTech) research group. Dr. Bers will present an overview of her interdisciplinary research program by using the metaphor of playgrounds vs. playpens to understand the role of technology in children's lives. She will provide examples using the two environments she created, the Scratch Jr. programming language and the KIBO robotic kit. The talk will cover ideas from her recent book "Coding as a Playground" where she argues that coding should be seen not only as a technical skill but as a new literacy - a new way for children to express and share their ideas. As a literacy, it carries power to change the world.
