A few thoughts:
1. I schedule a time about half way through the rehearsal period when I expect everyone to be off book with cues, then a couple of rehearsals later, off book without cues. I explain to them that it is embarrassing and annoying to stand up on stage without a clue, but I'd much rather they go through that pain now than later on in front of an audience.
2. I have always found that having understudies, and actually using them, will provide the push an actor needs to study.
3. I survey every new bunch of actors I work with about their favorite memorization strategy. Some can only memorize on their feet, preferably on stage. They run it, go back, and run it again.
Some read a script to themselves, over and over.
Some make a recording and play it back over and over.
Some work best with a partner, preferably a mean one, who will drill them over and over.
Some write the whole script out, several times.
Some use a combination of styles.
The one thing that all memorization styles have in common is that they have to be repeated.
I remind actors that the french word for rehearsal is
répétition.
4. I like telling young actors that lines are to acting as gas is to a car. You might look good, but you aren't going anywhere without it.
