I see your point students want to know that what they are studying will help them with a test. This is a problem in teaching. We teach to the book not to the out world experience. The point is hands on in actual doing to relate to the outside world in order to make learning engaging for the student. Go out into the world you’re not going to be given a test to pass with a grade. You will be given real world problems you need to solve a test won’t help you with that all it does is reinforce memorization without critical thinking. This is what education lacks, critical thinking. Take a student that knows math add world world applications to the math in order to solve a problem. Student will learn better, more engaged and have confidence that this works even when I’m out of school and can apply it.
