Problem: When the Scratch Cat is clicked, it should pace back and forth across the stage. It moves but it flips over -- and walks upside down! How do we fix the program?
The original debugging challenge was created by the ScratchEd Team as part of the Week 1, Day 4 activities for the Creative Computing Online Workshop. It (and other Debug-it projects) are being used in Computer Clubs that I mentor to find out a bit about the kids level of Scratch expertise. We (the teachers and I) are using it as a formative evaluation. My thanks to the ScratchEd Team.
