Key Takeaways:

When you "tell" your kids how to do something, it doesn't usually go over well, because they can either (1) get defensive, or (2) decide to shut down and not come back to you again when they need help with something
Kids are more receptive and reflective when asked what we call powerful questions: questions that get them thinking about when and how they will get their homework done or study for upcoming exams

Action Steps:

Test out a few powerful questions to ask the next time you're trying to get them to study. Like, "What's one way you will study for that test?" or "How will you know you've learned the information?"
When helping with homework assignments, try asking questions like, "Do you have notes with these types of problems?" to get them thinking back to how the teacher may have explained how to do it in class independently.
If you're feeling confident, consider previewing as a next step: looking ahead to what they have coming up next, so that they can understand the content ahead of time and focus better in class.
