In the past， we just take it for granted that a teacher's purpose is to teach students， he knew and solve all their problems. As a result， students can in this case the MOTOROLA's discretion. As a result， the students gradually lost the ability to learn itself. In addition， they are only equipped with the professor in class for each question， may suddenly appear in the same judgment. Of course， they will find their own knowledge to solve practical problems.
So， now is to change teaching methods. A teacher's goal is to help students to develop， not only the ability of learning， but their own skills， in every aspect of their judgment. That doesn't need to seek help from teachers when meeting with difficulties for students. First of all is to cultivate students' ability to make any problem， correct judgment and overcome the difficulties.
All in all， teaching is the goal of liberation， but MOTOROLA bound to make the right judgment inherent power of students.
