In this hands-on 90-minute professional development workshop, teachers will learn how to use CS First, Google’s free ready-to-teach introductory computer science (CS) curriculum for elementary and middle school students. Students follow step-by-step instructional videos that introduce fundamental computer science concepts and build computer programs using Scratch, a block-based programming language. During the 90 minute workshop, teachers will review the CS First curriculum, test drive a CS First class from a student and teacher perspective. Teachers will walk away with a plan of action and strategies for starting to teach CS First in their classrooms. Most importantly, teachers will join the growing community of CS First educators from around the world.
