You are in a mentoring/training relationship. There is no one right way to handle this situation, and there are no simple answers for HOW to do it effectively.
You might be successful with the advice given here, or you might find some other way to do it. Whatever the case, this is NOT an easy endeavor. It should be taken as a serious part of your daily work, not as some side-task where you can simply apply a few tips and tricks. In other words, it WILL take time out of your day and you must factor this into your other responsibilities. You basically have to carve out significant chunks of time and effort to do this right.
The good news is that training people can be highly rewarding to you personally, to the organization and to the students.
Pedagogy (teaching) requires the teacher (you) to evaluate the students and to take different actions depending on this evaluation. If you haven't taught before now would be a good time to research into it and start practicing this stuff.
There's no magic ratio of "spoon-feeding" to "self-reliance". If you think that your students aren't absorbing the information you're giving them, there could be any number of reasons for that: perhaps they need more practice? perhaps the information was not presented correctly? perhaps they don't have enough context? Whatever the case, you have to find out what the real problem is and address it (and no, the problem is NOT usually that the students are dumb or lazy).
