1, the teaching method is conducive to greatly improving the effectiveness and efficiency of classroom teaching.

This teaching method has two special advantages, namely universality and intuition. Teachers' teaching can turn abstruse and abstract textbook knowledge into concrete images and simple and popular things, thus eliminating students' mystery and fear of difficulties and making learning really possible and easy.

2. This teaching method is helpful for students to master the teaching materials comprehensively, profoundly and accurately, and promote the all-round development of students' academic ability.

As the blueprint of the subject knowledge system for students to learn, teaching materials not only collect systematic subject knowledge, but also contain many other valuable contents, such as subject thoughts, thinking methods and emotional factors. However, due to the limitation of written form and other factors, knowledge itself is not easy to be understood by students, and its hidden connotation is not easy to be discovered.

3. Teaching methods are conducive to giving full play to the leading role of teachers themselves and allowing students to get much more than textbooks.

Any truly effective teaching must be dissolved in teachers' own knowledge, cultivation and emotion, and reveal the truth, goodness and beauty in teachers' hearts. Therefore, teaching is not only the output of knowledge and methods, but also the display of teachers' inner world. It influences, infects and cultivates students' minds subtly. It can be said that it is a mirror for students to know life and the world, and it is also an important source of students' spiritual wealth.

Disadvantages:

1, teaching methods tend to make students feel dependent and expecting, thus inhibiting students' independence, initiative and creativity in learning.

2. Teaching methods easily make students produce "pseudo-knowledge", which leads to the disconnection between knowledge and ability.
