I am so happy to be able to follow this Getting Unstuck activity. much of the science I got.
I teach ICT courses at SIT Darul Abidin. We use scratch in the ICT teaching curriculum at our school. We used scratch within a year, but we've got a lot of experience in it. Hope I am more expert in using scratch. Ohh... Can't wait to meet with my students to teach me what I've got here.
