Zorin OS Education includes apps for teaching in preschool/kindergarden all the way up to tertiary/university level.
You can install any Linux-compatible apps in Zorin OS Education, as well as many Windows apps with the help of Wine. There’s a large library of apps you can install from the built-in Software store, which uses the Ubuntu & Zorin OS repositories as well as the Snap store by default. You can also enable the Flathub (Flatpak) repository to install apps from there by following these instructions: https://flatpak.org/setup/Zorin%20OS/
The operating system has been translated into over 50 languages, and most apps should work in at least the most common languages such as Spanish, Italian, French, German, Portuguese, and of course English.
