If you’re confused in school now, you can use that confusion to become a better teacher later. You can write detailed notes about what you’re confused about and and why. Doing this may help you to figure things out now, and it will definitely help you to teach well in the future.
Teaching is hard, and teaching beginners is often harder. Knowing a subject well isn’t the same as knowing how to teach it. Teachers need to be able to explain things in a way that will make sense to beginners. They also need to be able to figure out why students are getting confused, and find ways to help them understand. This is much easier said than done.
Right now, you’re probably confused about some things that will feel completely obvious in a year or two. Many things that are hard to master feel completely natural once you’ve learned them. It can be hard to understand why something that has come to feel completely natural to you is confusing to your students.
As a student, you’re likely confused about your subject; as a teacher, you are likely to be confused about your students. If you write down what you’re confused about as a student, you will be doing your future self a huge favor. The notes themselves may be helpful when you teach. Beyond that, writing notes about yourself as a student can help you to start thinking from a teaching perspective. The sooner you get into the habit of thinking about your subject with teaching in mind, the better off you’ll be in the long term.
Short version: If you’re confused in school, you can use your confusion to be a better teacher in the future. Consider writing down what you are confused about and why. In the future, you will have students who are confused. Understanding your own confusion now can help you to understand theirs later.
