High school is a good time to let go of the idea of "teaching" everything. What's important is that the students "learn". Sometimes that will mean finding self-teaching curriculum and allowing them to learn without your help. But sometimes "not teaching" really means letting go!
If your child loves something, and you see that it is your child's area of specialization, then you don't have to have control over it. Let your child experience and enjoy learning about the thing that interests them. You don't have to test, or have them write papers about it, or require an outline, or develop a learning plan. Let them just experience it! If they produce something, save it in your records. Perhaps they will make a short video or drawing for fun - don't test them to see what they know about shading or plot! Just save the item, rejoice that they are learning for fun, and don't stress about it! As they are learning for fun, think about what they used and keep track of it. It may be book titles you can save, but not always. It may be plays they went to, computer tutorials they viewed, or instruction manuals they read. You can save those ideas to include in a course description. It still doesn't mean you have to control what they do when they are learning! You're just writing down what they did while they were learning on their own.
