1, has a good interest in learning.
More than 2,000 years ago, Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy." It means that it is better to love something than to do it, to know it, to understand it, and to enjoy it than to like it. "Good" and "happy" mean willing to learn and enjoying learning, which is interest. Interest is the best teacher. Only when you are interested can you have hobbies. If you like it, you have to practice and enjoy it. With interest, we can form the initiative and enthusiasm of learning. In mathematics learning, we turn this spontaneous perceptual pleasure into a conscious and rational "understanding" process, which will naturally become the determination to learn mathematics well and the success of mathematics learning. So how can we establish a good interest in learning mathematics?
(1) preview before class, and have doubts and curiosity about what you have learned.
(2) Cooperate with the teacher in class to satisfy the excitement of the senses. In class, we should focus on solving the problems in preview, regard the teacher's questions, pauses, teaching AIDS and model demonstrations as appreciating music, answer the teacher's questions in time in class, cultivate the synchronization of thinking and teachers, improve the spirit, and turn the teacher's evaluation of your questions into a driving force to spur learning.
(3) Think about problems, pay attention to induction, and tap your learning potential.
(5) Let the concept return to nature. All disciplines are summarized from practical problems, and mathematical concepts are also returned to real life, such as the concept of angle, the generation of polar coordinate system and the generation of polar coordinate system are all abstracted from real life. Only by returning to reality can the understanding of concepts be practical and reliable and accurate in the application of concept judgment and reasoning.
2. Establish a good habit of learning mathematics.
Habit is a stable and lasting conditioned reflex and a natural need consolidated through repeated practice. Establishing a good habit of learning mathematics will make you feel orderly and relaxed in your study. The good habits of high school mathematics should be: asking more questions, thinking hard, doing easily, summarizing again and paying attention to application. In the process of learning mathematics, students should translate the knowledge taught by teachers into their own unique language and keep it in their minds forever. In addition, we should ensure that there is a certain amount of self-study time every day, so as to broaden our knowledge and cultivate our ability to learn again.
3. Consciously cultivate your abilities in all aspects.
Mathematical ability includes five abilities: logical reasoning ability, abstract thinking ability, calculation ability, spatial imagination ability and problem solving ability. These abilities are cultivated in different mathematics learning environments. In the usual study, we should pay attention to the development of different learning places and participate in all beneficial learning practice activities, such as math second class, math competition, intelligence competition and so on. Usually pay attention to observation, such as the ability of spatial imagination is to purify thinking through examples, abstract the entities in space in the brain, and analyze and reason in the brain. The cultivation of other abilities must be developed through learning, understanding, training and application. Especially in order to cultivate these abilities, teachers will carefully design "intelligent courses" and "intelligent questions", such as multi-media teaching such as solving one question, training classification by analogy, applying models and computers, which are all good courses to cultivate mathematical abilities. In these classes, students must devote themselves to all aspects of intelligence and finally realize the all-round development of their abilities.
First, cultivate interest. A strong interest in learning will make students in a positive mental state, with keen observation, quick understanding, strong memory and rich imagination, and at the same time, they will have a positive enthusiasm for exploration. Interest in learning chemistry is the driving force to learn chemistry well, and interest in chemistry is the premise to learn chemistry well. Interest is the best teacher.
Second, have good study methods and form good study habits.
2. Listen carefully, take notes, listen carefully in class, think positively, and learn to listen. For example, the teacher talks about chemical reaction equations and listens to the teacher to analyze the reaction process, so we can't just remember the results. The teacher does demonstration experiments and carefully observes the operation methods and experimental phenomena of the demonstration experiments. When the teacher talks about calculation, he should listen to the problem-solving ideas, master the problem-solving methods, learn to standardize the problem-solving steps, temporarily put aside what he doesn't understand, and then ask the teacher to answer the remaining questions after class. There are many knowledge points in chemistry, so it is very important to take notes in class. There are some simple notes in the book and some detailed notes that are not in the book. Key points, difficulties and details. Take notes and attend class at the same time. You can't just listen without taking notes, and you can't just take notes without listening to lectures.
3. Review in time to avoid learning confusion. Review is not just a simple review of knowledge, but a process of summarizing and sorting out what you have learned in your own brain and forming a knowledge network. Deepen the understanding and mastery of knowledge through review, and avoid learning confusion. For example, after learning isomers, we will compare them with homologues, allotropes and isotopes when reviewing, and find out the differences between the four concepts, so as to deepen our understanding of the concepts.
4. Standardize problem solving to ensure the quality of homework. When you do your homework, you should read a book first, organize your notes, and then do your homework. Homework should be carefully standardized, done in the required format, and not sloppy. After finishing, we should carefully check whether there are any mistakes, consciously be strict with them, and finally summarize the questions answered to cultivate a rigorous learning attitude in solving problems.
5. Do some exercises, draw inferences from others and sum up the rules. Doing problems is an important way to understand, digest and consolidate knowledge. Choose targeted exercises and don't fall into the tactics of asking questions. We should aim at mastering problem-solving methods and skills, pay attention to induction and summary, and master the skills of drawing inferences from others. For example, the skills to solve the problem of inorganic block diagram reasoning are: characteristic physical properties cut-in, trial and error, computational reasoning, logical reasoning, and high-frequency information cut-in. The commonly used technical methods in chemical calculation include: conservation method, difference method, estimation method, average method, cross method, relationship method and so on. 6. Insist on summing up, form a habit, and develop a good habit of summing up. Regular self-summary is an important part of learning chemistry well. Through summarization, knowledge is organized, systematized and networked. The forms of summary include chapter knowledge summary and special topic summary. The summary includes knowledge points, problem-solving methods, error-prone points and so on. The methods of summary include the networking of knowledge points, skillful problem-solving methods and clear mistakes. For example, the knowledge summary of elemental compounds takes knowledge points as clues to form a knowledge network. The knowledge summary of iron and its compounds can build a knowledge network. The summary of chemical calculation can take the problem-solving method as a clue and summarize the problem-solving skills. Common methods include relation method, conservation method, difference method, estimation method, crossover method and average method. In this way, if you persist in summing up and form habits, your academic performance will continue to improve.
7. Pay attention to the cultivation of multiple abilities in chemical experiments. Chemical experiments are divided into four categories: demonstration experiments, experiments while talking, experimental classes for students and experimental exercises. Demonstration experiments are operated by teachers, and the last three are conducted by students. Teachers' demonstration experiments can help students understand the physical representation characteristics, material change conditions, phenomena and laws, help students form concepts smoothly and be convinced of the authenticity of theories, cultivate students' observation, analysis and comprehensive abilities, and also show students' correct experimental operation, rigorous scientific attitude and working methods. Students' hands-on experiment means that students independently use what they have learned to carry out experimental operations, observe experimental phenomena and make experimental records, so as to observe experimental phenomena more carefully, have a deeper impression on the obtained substances and their changes, and thus have stronger knowledge. No matter what kind of experiment, we should pay attention to it. In the experiment, we should see more, do more, think more, think more and ask more why, so as to know what it is and why, and cultivate the ability of observation, experiment and analysis.
8. Establish a question bank for learning and reflection. Put the exercises and test papers issued by the teacher in the self-provided exercise bag for easy search. At the same time, correct the wrong exercises with a red pen. For each mistake, carefully analyze the reasons for doing it, whether the knowledge points are not remembered, or the questions are wrong, or the knowledge is not applied, or sloppy. You can't simply write the answer. Write the wrong reason in red pen as a warning. After a period of accumulation, you will find yourself having problems in your studies. If the knowledge points are not accurate, we should strengthen our memory. If you are careless, you should be careful in the future. Do more questions if you can't use them. Take out the wrong questions and redo them every once in a while. After such a change, you will be deeply impressed, so that you won't even make such mistakes in your future study.
9. Learn to remember skillfully and get twice the result with half the effort. There are many things to remember in chemistry. It is difficult to learn by rote. Even if you remember it temporarily, it will be blurred after a long time. Therefore, it is very important to remember skillfully. Commonly used memory methods include: understanding memory, inductive memory, formula memory, comparative memory and so on. For example, the hydrolysis of salt can be compiled into a formula, "If there is no weakness, it will be hydrolyzed, whoever is weak will be hydrolyzed, the weaker it will be, and the weaker it will be, the more neutral it will be." The naming of alkane system can be compiled into the formula "choose the main chain and call an alkane;" Digital position, fixed branch chain; Substituent, written in front, marked position, short line connection; Different bases, simple to complex, same base, combination. "The writing of alkane isomers can be compiled with the formula of" main chain from long to short "; Branching from whole to dispersion; (of branches) from the center to the edge; Carbon (atom) satisfies four bonds; Don't repeat the calculation. " Learn to remember skillfully, get twice the result with half the effort.
10. read textbooks and extracurricular books to expand your knowledge. There are many knowledge points and memories in chemistry. Be sure to read books after class, master concepts and memory properties through reading, and have at least one chemistry reference book.
