The problem of knowledge is a fundamental issue of modern school education.Without knowledge,there is no need for teaching; without systematic scientific knowledge,there is no need for modern education.Knowledge used in teaching is an important way to cultivate students.Its inheritance is also the essential task of teaching.Knowledge inheritance and student developments are mutual purposes and tools.Knowledge teaching is the ladder of human civilization progress,enabling students to walk into history with enriched spirits.Leading students to learn indirect,advanced,and systematic scientific knowledge is the advantage and specialization of teaching activities.Through students’ initiative activities,objective knowledge can be activated and embodied,and become the real power for students’ growth and creation.
