Teachers usually explain the ins and outs of knowledge in class, analyze the connotation and extension of concepts, analyze key points and difficulties, and highlight thinking methods. But some students don't pay attention in class, don't hear the main points clearly or can't hear them completely, take a lot of notes and have a lot of problems. After class, I can't consolidate, summarize and find the connection between knowledge in time, but I am busy with homework and confused questions, and I know little about concepts, laws, formulas and theorems.

Mathematics discipline must cultivate the ability of calculation, logical thinking, spatial imagination and the important task of analyzing and solving problems by using the learned knowledge. Its characteristics are high abstraction, strong logic, wide applicability and high requirements for ability. Mathematical ability can only be cultivated and improved through continuous reflection on the application of mathematical thinking methods. The content of mathematics changes greatly, and the learning method is backward. In the process of learning high school mathematics, you will certainly encounter many difficulties and problems. Students should have the courage and confidence to overcome difficulties, be proud of victory, be indomitable in failure, and never let problems pile up and form a vicious circle. Instead, we should seek solutions to problems under the guidance of teachers and cultivate our ability to analyze and solve problems. This is the best understanding.

Learn to find problems and pay attention to questioning students who often see good grades in their studies. There are always many questions to ask the teacher. Asking questions is not only the starting point of discovering true knowledge, but also the beginning of invention and creation. The process of improving academic performance is the process of finding, asking and solving problems. Boldly questioning the teacher is not a manifestation of stupidity, but a manifestation of pursuing true knowledge and being proactive. In class, we should not only "know why", but also "know why", so that problems can continue to arise, and then we can analyze and think about solving problems and make progress in learning.
