I consider that most of my education and reason why I can live comfortably comes from constructionism and free software! That being said, it's not a silver bullet, it sits on top of a heavy infrastructure both material and social that made it work :)
I wouldn't define any software as constructionist, but rather certain usage as constructionists.

I think the graphical nature of the language might make it more approachable [citation needed] by giving you some visual hints about you how you can combine the grammar's atoms.
What's for sure is that Scratch is meant to teach you programming by letting you play with programs other people created before allowing you to see and modify what's under the hood via the "remix" feature.
