What WM is used with Edubuntu?

[Cybe R. Wizard]

Although I have Edubuntu installed, it is over a regular Ubuntu system
with Kubuntu and Xubuntu also installed.  Now I find I can't tell what
window manager/desktop environment is standard for Edubuntu.  I am
trying to 'sell' a  friend on Edubuntu for his kids and found that I
don't know the answer to this.
Can you fine people help?
