Use of one dreamweaver license in multiple computer

Creative Cloud apps can be installed and activated on up to 2 computers -- home/office or desktop/laptop.  But only one device may be used at a time.  And your plan is for a single user only.  No sharing allowed.  Adobe does not offer family plans at this time.

For personal use it is allowed to install on 2 computers. The student version requires a student ID from a high school or university since they have to be 13 to purchase and it has to be by the student.  

If you are trying to teach code, I don't know whether DW is your best option for doing this. Personally, I would consider looking into the free Visual Studio Code ( https://code.visualstudio.com ).  There is a Mac and a Windows version and it's all about code. If you are doing web coding you can always install a MAMP/WAMP solution to have a server on your local machine to do that.
