This looks like a valuable free professional development course for teachers interested in incorporating Scratch into their curriculum.
“The Scratch Course” is a free, six week, online workshop style course for teachers interested in learning more about programming with Scratch. Originally created through funds from Google’s CS4HS program, this course has served over 1000 teachers from around the world in the last five years. We are preparing to offer our fall 2019 section of the course starting on Monday, September 16. For more information about the course and to pre-register, visit: https://csed.uni.edu/scratch-intro/
