Exploring Code Smells in code written by Children with Dr. Felienne

Felienne is always learning. In exploring her PhD dissertation and her public speaking experience it's clear that she has no intent on stopping! Most recently she's been exploring a large corpus of Scratch programs looking for Code Smells. How do children learn how to code, and when they do, does their code "smell?" Is there something we can do when teaching to promote cleaner, more maintainable code?
