In the past, the three-dimensional goals of teaching were: knowledge and skills, process and method, emotional attitude and values. Now the four-dimensional goals are: knowledge and skills, mathematical thinking, problem solving and emotional attitude. It should be said that moral education is the first, the cultivation of innovative ability is the second, and the knowledge process and method are the foundation. A person's realm determines his development, his ability determines his performance, and his knowledge determines his adaptability. People with brains, knowledge and ability are needed by society. I believe you will become a pillar of the country.
