Gagne's nine steps of learning was criticized because it is insufficient for self-learning and ineffective in adult teaching. Do you agree with this statement? Why/why not?

I don't think in that way just because of his military purpose. I think Gagne's nine steps of learning is really successful. All steps are really good for the instruction. However, recording the characteristic of the learners is the most effective way of learning for the students because different students have different intelligence. So by knowing them, instructors can be more expericenced  and they can know how to teach students in a controlled manner. Thus, I believe this Gagne's conditions of learning should not be named as a insufficient and ineffective.
