The difficulties in the second day of junior high school often appear in mathematics and physics. It is often heard that "several things are flat and the geometry is good." It means that if you learn plane geometry well, you will basically pass math.
On the one hand, many front-line teachers learned plane geometry well in their second year of high school, and have been good at mathematics since then; I didn't learn plane geometry well in the second grade, and mathematics has been unsatisfactory since then. It is really difficult for girls to learn plane geometry.
On the other hand, learning plane geometry well is the guarantee for us to do a good job of geometry synthesis finale and quadratic function finale in senior three. If we don't learn quadrilateral well, senior three will face great difficulties, and plane geometry is also the basis of analytical geometry and solid geometry in our senior high school. So plane geometry must not be relaxed, especially congruent triangles and quadrilateral.
Teacher Wu of junior high school mathematics
Teacher Wu, the forerunner of junior high school mathematics teaching.
He has devoted himself to junior high school mathematics 10 for many years and is a humorous teacher.
Motto: It is better to teach people to fish than to teach them to fish.
Teaching subjects: mathematics in primary and secondary schools
Teaching Campus: Wuhan Zhongnan Fast Learning Education
Mr. Wu is a humorous and relaxed professor who pays attention to learning methods and problem-solving skills. He always believes that teaching should not only teach learning methods and skills, but also let children learn in happiness and enjoy in learning.
Teacher Wu said: The second grade is prone to what we call "the first grade is neck and neck, and the second grade is high and low". At this time, many students will relax and feel that there is no momentum on the first day. It's easy to get distracted in class, don't understand what the teacher says, or think that what the teacher says is too simple, which will have a great impact on his study, and in serious cases, he will be devastated. In view of this, we must first encourage ourselves, believe that I can do it, listen carefully to what the teacher says, and actively digest and absorb it; Secondly, we must not relax the in-depth excavation of knowledge points, as well as the extension and expansion of knowledge points, and practice more classic questions; Thirdly, learning must not be interrupted at this moment, whether it is tutoring or extracurricular remedial classes, we must keep up with the pace of teachers. Only in this way can we overcome the "syndrome" and usher in our own victory!
Brief introduction of mathematics learning methods in Grade Two;
A. Prepare well before class and take the initiative in class. Everything is established in advance, and it is abolished if it is not foreseen.
B. Listen carefully in class and take notes. You should enter the state in advance in class. The quality of preparation before class directly affects the effect of listening to lectures.
C. review in time and turn knowledge into skills. Review is an important part in the learning process. Review should be planned, not only to review the lessons of the day in time, but also to review all stages in time. I will review, think and summarize what I learned last week, last month and this semester. It is best to use the winter and summer vacations to review and consolidate all the contents before last year or this semester. At this stage of learning, it is best to consult and verify the contents that were not clear in the past. Mathematics is not a particularly outstanding student, and generally lacks confidence in learning mathematics well. If they persist in this way for two to three years, they will gradually perform well in their daily homework and classroom performance, and their confidence in learning mathematics will gradually be established, and their math scores will naturally get better.
D. Finish homework carefully, form skills and skills, and improve the ability to analyze and solve problems. Academician Yang Le, an educational authority, answered the question of how middle school students learn mathematics well in just three sentences: First, practice more on the basis of understanding; Second, accumulate more on the basis of understanding; Third, step by step. The exercise here is to do the problem and finish the homework. The exercises mentioned here, on the one hand, are to do exercises, complete homework and further reflect on the wrong questions, think thoroughly, find 3 to 5 similar questions, and achieve thorough mastery, consolidation and improvement. On the other hand, combined with my own life experience, I use what I have learned to analyze and explain some problems in my life.
