No, not necessarily.
This completely depends on the wallet used.

If using electrum for example, transactions using the imported private key will send the change back to the original address.
I still think it's a bad practice to import private keys and only spend them partially, especially for a newbie. Until a new user gets the hang of how wallets and coin control work, it's safer imo to transfer the entire balance instead.

I disagree. By transferring less funds, there are fewer bitcoins on the table to lose if they accidentally bork their transactions.

People shouldn't have to know how coin control works or that an address can have many inputs associated with it in order to be able to send from a single address.
