(1) subject change: Compared with Grade One, Grade Two begins to add geometry and physics, both of which require strong thinking training, directly serving for entering a higher-level subject or employment.

(2) Changes in discipline thinking training: All disciplines in Grade Two put forward higher requirements than Grade One in terms of concept evolution, reasoning requirements, comprehensiveness, profundity, rigor and creativity of thinking.

(3) Internal changes in thinking development: From the perspective of thinking development psychology, thinking development has entered a new stage, that is, it has entered the peak of the fifth leap period violently and sharply. Whether this "leap" cycle will be shortened and whether the quality of "leap" is ideal depends on two conditions: first, the careful guidance of teachers; Second, students' unremitting efforts.

(4) Changes of external interference factors: The second day is the age when the pace of personality stereotypes is accelerated and the fantasy is heavy, which is often manifested as psychological state and emotional instability, such as rebellious emotional development. This creates conditions for the temptation and interference from outside to take advantage of it and take advantage of it. Don't let these prevent students from receiving the guidance of teachers and parents normally; It destroys the normal psychological state of students to concentrate on their studies. We should learn to be "calm" and "self-restrained" and put abundant youthful vitality into learning activities.

The second day is indeed an important period. The mastery of knowledge at this stage directly affects the results of the senior high school entrance examination. However, learning is not absolutely "easy". If you want to finish the learning task of senior two relatively easily, you can start from the following aspects:

Second, the second stage of learning focuses on clear priorities.

First, prioritize. Mathematics, Chinese, English and physics should be arranged as key points. In addition to listening carefully in class, 70% of the energy after class should be spent on these main courses. In the second day of junior high school, every main course should have an extra-curricular book, so it is necessary to do some exercises after class. In the second half of the second semester of Grade Two, geography and biology will be finished, so you can listen to the class well and master the necessary knowledge. History is an open-book exam. Besides textbook knowledge, we should also pay more attention to current events.

Second, we should arrange the study time reasonably. People have the best memory in the morning and are suitable for reading English and memorizing words. During the day, self-study classes are arranged for mathematics and physics, and the efficiency of solving problems is higher at this time. The rest of the time will be reserved for Chinese, so you can read more extracurricular books. When you meet good articles and paragraphs, you should copy them down and accumulate materials, so that writing will be easier. When reviewing at night, don't be tired. You can listen to music, do some less intense indoor sports, relax, and your learning efficiency will be greatly improved.

Third, enter each prepared class and listen to the class with interest, questions and purpose. Prepare what? That is, according to the course arrangement, preview the weak courses in a targeted manner. When previewing, we should make clear the content of the next class, which is clear, which is vague and which is not understood, so as to determine the focus of listening. Summarize after class, summarize the framework of knowledge, and then do related exercises.

Fourth, get rid of the embarrassing feeling, communicate with classmates more, and find other people's good ideas, methods and mentality in the discussion. This kind of close communication will make you integrate with everyone and reduce the psychological pressure of learning. At the same time, relax your learning attitude, and the effect of attending classes will be improved quickly.

Fifth, learning, the role of "learning" determines whether the result of learning has a good effect. After each class, read some related materials and do some related exercises. There are many materials now, which one is better? Which is suitable for your situation? I glanced at it in front of the information shelf in the bookstore, and which one you feel comfortable with. If you still feel uncertain, you can substitute for the teacher.

Sixth, carefully arrange review, develop good study habits and prepare more notebooks at ordinary times. Write down the questions you don't understand and the problems that are easy to make mistakes in time. In this way, review can be targeted and orderly.

How do senior two students avoid polarization?

There is a saying in junior high school teaching: "The first day is evenly matched, the second day is polarized, and the third day is harmonious." According to the annual statistics, there is a serious trend of two-level differentiation in mathematics learning for students entering the second grade of junior high school, and the proportion of underachievers is large, which directly affects the improvement of mathematics teaching quality. The reasons for the difference in Grade Two are as follows:

1, lack of interest in learning mathematics and weak will to learn are the main internal psychological factors that cause differentiation.

2. The knowledge and skills are not systematic, and a good mathematical cognitive structure has not been formed, which cannot provide the necessary cognitive basis for continuing learning.

3. The way of thinking and learning methods can't meet the requirements of mathematics learning.

There are several ways to avoid differentiation and really learn mathematics well:

(1) Learn the trilogy, complete the preview in advance, pay attention to the lectures in class, and review in time after class.

Before accepting new knowledge, you should complete the preview in advance. In addition to studying other courses in advance, you should preview the knowledge of the next day every night, so that you can listen better in class and get high-level gains. The cultivation of mathematical ability is mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek the correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. Finish your homework carefully and be diligent in thinking. In a sense, you shouldn't create a learning style of asking questions if you don't understand. For some problems, it is difficult to solve them for a while because you are unclear. You should calm yourself down and try to solve them as much as possible. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system.

(2) Do more questions appropriately and develop good problem-solving habits.

If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to solve problems and master the general rules of solving problems. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, enter the best state, and use it freely in the exam. Practice has proved that at the critical moment, your problem-solving habit is no different from your usual practice. If you are careless and careless when solving problems, it is often exposed in the big exam, so it is very important to develop good problem-solving habits at ordinary times.

(3) Adjust the mentality and treat the exam correctly.

First of all, we should focus on basic knowledge, basic skills and basic methods, because most of the exams are basic topics. For those difficult and comprehensive topics, we should seriously think about them, try our best to sort them out, and then summarize them after finishing the questions. Adjust your mentality, let yourself calm down at any time, think in an orderly way, and overcome impetuous emotions. In particular, we should have confidence in ourselves and always encourage ourselves. No one can beat me except yourself. If you don't beat yourself, no one can beat my pride.

Be prepared before the exam, practice routine questions, spread your own ideas, and avoid improving the speed of solving problems on the premise of ensuring the correct rate before the exam. For some easy basic questions, you should have a 12 grasp and get full marks; For some difficult questions, you should also try to score, learn to score hard in the exam, and make your level normal or even extraordinary.

Recommend several good memory methods

Practice reciting. Some things that can be memorized by hand can be practiced, tested and experimented by yourself to enhance the memory effect.

Skeleton memory method remembers the general outline first, and then gradually remembers every detail, from coarse to fine.

Contrastive memory method can compare two things and find out the similarities and differences when remembering similar things.

The classified memory method outlines the content to be memorized, sorts it out, and then memorizes it.

The key memorization method memorizes the formulas, theorems, conclusions, basic concepts and important sentences in the whole content as a "chain" of memory.

To understand the mnemonic method, only the knowledge with deep understanding can be firmly remembered.

Inferential memory method uses one thing to lead to a close thing or a causal thing to remember.

If the network memory method can connect all the knowledge points learned into a line, form a surface and weave a network, then the differences between the various parts of knowledge will be clearly visible.

However, there are no shortcuts to learning, and some so-called shortcuts often make you take many detours, so you still have to work hard on your own!

How to improve memory?

Students often complain that they have poor memory, forget what they have just learned and have low reading efficiency. In fact, this is mostly caused by improper learning methods. Some students have no idea about what books to read and what tasks to accomplish today, and the result can of course be imagined. In an experiment, two classes were asked to answer a simple question: How many steps are there in the school building? Students in Class A and Class B have to go through the same ladder in class and class. As a result, no one in Class A answered because they didn't assign tasks in advance. The students in Class B got it right because they assigned this task. This experiment has given us great enlightenment, that is, learning should have clear goals. The so-called goal learning method means to have clear goals and specific learning tasks in the learning process.

Taking Chinese learning as an example, we can target, concretize or quantify the learning task of each text and complete it in several units. Might as well have a try.

In the first unit, I will learn punctuation marks in the text and find out the function and usage of each punctuation mark in the text. If you don't understand, you can break through the knowledge of punctuation in a short time by asking the teacher or looking up information.

The second unit time, the goal is to master the pronunciation, strokes and body structure of new words in the text.

The third unit is devoted to drawing words, beautiful sentences and idioms to understand their meanings and the source of words, which not only consolidates knowledge, but also expands knowledge.

Unit 4 time can be the structure of the article, summarizing the center of the paragraph and the full text, learning and summarizing the thinking method. Unit 5 Time is used for reading and reciting texts.

In this way, the knowledge of a text is broken one by one, and the effect of getting twice the result with half the effort is achieved.

This target teaching method is also applicable to other disciplines.

Let me introduce some of my experience in reciting for your reference.

First of all, I divide the text into many small paragraphs. A short paragraph is a meaning or a complete event. In short, it is divided according to the method you are familiar with, and you don't have to stick to the form.

Then break through these small pieces one by one. Understand the overall meaning of each paragraph first, and then recite it sentence by sentence. Look at the sentences and say them out loud. After each sentence is finished, try to say the whole sentence out loud with your back to you. Then compare it with the original text to see if there are any mistakes. In this way, after reciting each paragraph, you can try to recite the whole article. The process is the same as reciting a paragraph. If an article is too long, consider dividing it into several large pieces, and treat each piece as the whole article mentioned above.

The above is just taking reciting the text as an example to introduce my reciting method to you. In fact, there are many good methods, each of which is suitable for different people. You need to learn from other people's methods and find the one that suits you best. At the same time, please remember that memory needs constant exercise. As long as you keep reciting, your memory will get better and better.
