MassCAN (the Massachusetts Computing Attainment Network) is offering a free workshop for middle-school teachers on February 16-18, 8:00AM-3:30PM on Project GUTS — Growing Up Thinking Scientifically.  GUTS is a STEM program for middle-school students that is working with Code.org to deliver four instructional modules and professional development for the introduction of computer science concepts into middle-school science classrooms within the context of modeling and simulation (see curriculum here).   This workshop will be held at the Education Development Center, 43 Foundry Ave. in Waltham.  It will be followed by three half-day meetups for educators to review curriculum, answer questions, and share experiences.  Teachers will be paid a
stipend for their participation and implementation.  Register online.  Bring a laptop.  For more information, contact Kelly Powers at kpowers@edc.org or 617-618-2818.
