Huang Aihua: The Key to Implementing "Big Problem" Teaching
Mr. Tao Xingzhi said: "Life is about big problems." The "big problem" teaching we advocate is put forward after paying attention to the big problems such as mathematics teaching, teaching methods, education behind teaching behavior and development trend, focusing on the overall situation and exploring in depth. In teaching practice, we have gradually formed the connotation expression of "big problem" and the key to implementing "big problem" teaching.

Tip 1: study the text to help "big problems" sprout. The big problem that points to the subject refers to adopting certain teaching strategies according to students' specific psychological characteristics, learning experience and learning confusion, and systematically dealing with curriculum relations, problem guidance, learning methods and other aspects, so as to break through the main contradictions in teaching to the greatest extent, such as high quality, extensive extension, wide topic coverage, precise quantity and strong challenge. In the teaching of "big problems", the emergence of big problems is a difficult and important point. Only by studying the text carefully and grasping the core vocabulary can the "big problem" come to the bottom.

Tip 2: In-depth dialogue leads to "big problems". The teaching of "big questions" is not simply to answer questions according to the teaching plan. The teaching of "big problems" should ensure that students' subjectivity is highlighted. Dialogue in teaching is not only a conversation between the two parties, but also an opening of their inner world. They sincerely listen to and accept each other, and realize the blending of wisdom and emotion in the process of mutual acceptance and listening. The teaching of "big problems" in mathematics is a dialogue based on mathematical thinking and centered on speculative confrontation and wisdom growth. In-depth dialogue around "big problems" is a thinking process to guide students to observe, analyze, summarize, analogize, abstract and generalize, and it is also the teaching focus to guide the implementation of "big problems".

Tip 3: Give up the podium and make room for "big problems". In order to give students more autonomy in learning, we advocate giving the podium to students and let them be "little teachers". Advocating to cultivate the discourse system of "Mr. Xiao"; Please listen to me; What I want to tell you is ... what I want to emphasize in particular is ... Do you have any questions for me? This systematic language not only does not deprive students of their autonomous position on the podium, but also helps them find words, choose useful words and interact with other students successfully. The big space of "big problem" teaching is "let" by teachers and supported by teachers' firm beliefs. Only by maintaining scientific teaching beliefs can we better make room for the teaching of big topics.

Tip 4: Infiltrate ideas and show the charm of "big problems". Let students study big problems in the classroom, and teachers' teaching should give big space and present a big pattern. If the pattern of education is really to be enlarged, we should focus on the height of human growth. Education is the education of people's spiritual consciousness. It is not a simple teaching strategy and method, but more importantly, the consciousness of spiritual consciousness and the meaning of life. This determines that education is a difficult, laborious, complex and long-term job. We are increasingly emphasizing that education needs lasting attention and patient waiting, so that students can understand where they are going and where the teacher will lead me. This is not only the enlightenment of knowledge, but also the enlightenment of thought.
