Does good math necessarily mean good science? Thank god, help me.
Textbooks for thorough understanding of Chinese. The ideological content of each text should be analyzed, practiced and annotated clearly. Recite famous poems; Usually read a lot; Practice writing as soon as you are inspired. English "has an indomitable spirit in its bones". Chen Xinxin, the top science scholar in Chongqing, has a poor English foundation, which has always been a stumbling block for her. It is with this character that she has defeated her opponents again and again. In order to improve her English, she practices English hard in three classes every day: she teaches herself half an hour in the morning; Do three readings a day during the day (practice reading, cloze); After finishing my normal homework in the evening, I read English magazines, read simple English books and do a lot of intensive reading/extensive reading listening exercises. Usually, she pays attention to the accurate understanding of various knowledge points and grammar, and gives inferences to sort out the context of knowledge. She reviews words, texts and grammar for a week on Saturday and Sunday. After two years of close contact with English, she scored 139 in the college entrance examination in 2005. Mathematics to learn mathematics well must meet the following conditions: 1. We should not only master every knowledge point in the textbook, but also understand every knowledge point in place. 2. Accumulate problem-solving skills of various types of questions. 3. Master several mathematical ideas and thinking skills. 4. Write quickly. Function is the focus of high school mathematics, including important mathematical thinking methods in mathematics; For example, the idea of functions and equations, the idea of combining numbers and shapes, and so on. This is also the focus of the college entrance examination. The number of questions accounts for more than 60% of the whole test questions. The specific requirements for mathematics learning are as follows: 1. Cultivate a good interest in learning 1. Preview before class, 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. Pay attention to the teacher's mathematical thinking when explaining in class, and ask why you think so. How did this method come about? 3. Think about problems, pay attention to induction, and tap your learning potential. 4. Let the concept return to nature. For example, 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, the understanding of concepts will be practical and reliable, and it will be accurate when applying concept judgment and reasoning. 2. Establish a good habit of learning mathematics. Ask more questions, think hard, be practical, summarize again, and pay attention to application. In addition, it is necessary to ensure that there is a certain amount of self-study time every day to broaden the knowledge and cultivate the ability to learn again. 3. Pay attention to mastering concepts and basic knowledge; When doing the problem, we should make clear what concepts and operations are involved in the problem, and then master the basic methods and laws of solving the problem; In the process of learning, understanding, training and application, consciously cultivate their own logical reasoning, abstract thinking, computational space imagination and problem-solving ability. 4. Some suggestions: 1. Take math notes, especially the different aspects of concept understanding and mathematical laws, and the extra-curricular knowledge that teachers have added to prepare for the college entrance examination. 2. Establish a math correction book. Write down error-prone knowledge or reasoning in case it happens again. Try to find the wrong mistakes, analyze them, correct them and prevent them. 3. Memorize mathematical laws and conclusions. 4. Establish a good relationship with classmates, strive to be a "little teacher" and form a "mutual aid group" for math learning. 5. Try to do extra-curricular math problems and increase self-study. It is necessary to develop good habits of calculation and checking calculation, improve calculation ability, and pay attention to the speed and accuracy of mathematical calculation. 6. Repeatedly consolidate and learn to summarize and classify. It can be classified from the aspects of mathematical thinking, problem-solving methods and knowledge application. Most students who have studied physics, especially those who have poor grades in physics, always have such a question: "You can understand clearly in class, but you can't do problems after class." This is a universal problem worthy of serious consideration. In fact, if you want to go from understanding to doing, you should practice more, think independently and sum up frequently on the basis of listening to the teacher's lectures and solving problems carefully-classify and sort out the classroom knowledge in detail, especially the theorem, understand its connotation, extension and scope of application, so as to master its laws and secrets and truly become your own thing. This is exactly where you should study physics hard. The following analysis is divided into several levels. 1. Memory: In the study of physics, we should memorize basic concepts, laws and some basic conclusions, which is the so-called most basic knowledge. To learn the basic concepts, theorems and laws of physics well, you should do experiments by yourself, write experimental reports carefully, and have a clear image foundation. 2. Accumulation: on the basis of memory, we constantly collect a lot of information related to physical knowledge from textbooks and reference materials-examples; Illustrations in exercises; Reading materials and so on. In the process of collecting and sorting out, we should be good at analyzing and classifying different knowledge points and finding out similarities and differences. The process of accumulation is a process of struggle between memory and forgetting. It is necessary to make knowledge more comprehensive and systematic through independent thinking and repeated memory, and to make formulas, theorems and laws more closely linked. 3. Synthesis: The chapters of physical knowledge are both related and different. Therefore, small synthesis should be carried out continuously in the process of physics learning, and systematic synthesis should be carried out after the end of senior three knowledge learning. The contents of chapters are interrelated, and different chapters can be compared with each other, so that the knowledge of force, heat, electricity, light and elements (atomic physics) can be truly integrated, so as to gradually find the connection of knowledge from the synthesis and find the interest in learning physics knowledge. 4. Improve: On the basis of memorizing and accumulating knowledge and carefully synthesizing, improve the ability to solve and analyze problems. For a topic, we should first look at what the problem is-mechanics, heat, electromagnetism, optics or atomic physics, and then make clear the research object, and apply relevant physical concepts and laws in combination with the conditions given in the topic. Sometimes we can use some first-class and second-class conclusions in physics to get a smooth result. Imagine that if the basic concept of physics is unclear, the given conditions or implied conditions in the topic can't be seen, or the formula to be used in solving the problem is wrong, or the primary and secondary conclusions are used, and the original formula is used, then the speed and correctness of solving the problem will be affected. Therefore, this link requires: first, to be skilled in solving problems, second, to be flexible in solving problems, and third, to be innovative in solving problems (including multiple solutions to a problem, and choosing the simplest method from multiple solutions; It also includes multiple solutions to one problem, a method to successfully solve multiple similar problems). Really skilled use, relaxed and comfortable. In the process of physics learning, you should have a physical picture in your mind, which can be transformed into basic concepts, laws and theories, and then into mathematical forms to solve practical problems. According to the cognitive process from simple to complex, this paper compares the six levels of learning: first understanding, then memorizing, practicing and using, gradually mastering, practice makes perfect, being brave in innovation, constantly making progress and making great achievements. High school chemistry is full of details and comprehensive knowledge, so we should pay attention to grasping the foundation, ideas and laws in depth and breadth: 1. Have a solid grasp of basic knowledge and remember what you should remember. The periodic table of elements, typical chemical reactions and theorems should be memorized on the basis of understanding, and their internal relations and laws should be mastered. Only by mastering all the basic knowledge, can we complete all kinds of exercises in the design of teaching materials and supporting exercises, solve some comprehensive and difficult problems and adapt to all kinds of college entrance examination questions. It can be said that the mastery of basic knowledge has prepared the necessary quality for the college entrance examination. 2. Improve class efficiency and take notes. High school teachers should spend a lot of time and energy preparing lessons. The content of preparing lessons is substantial, detailed and extensive, and incisive knowledge can be taught in class and counseling. As long as students listen carefully, take notes carefully and understand and write down everything the teacher says, they will basically master what they have learned. According to the research of psychologists, people's attention can't always be in a state of excitement, and it will cycle from high tide to low tide every 7-8 minutes. Therefore, high school students should cycle their attention three or four times in each class, and students should learn to control their attention and focus on difficult knowledge to adjust their attention in an excited state. Chemistry is a science based on experiments. We must do experiments carefully, master the correct operation methods, observe the phenomena carefully, pay attention to the intermediate process, draw correct conclusions through analysis and reasoning, and understand the basic concepts and principles. By concretizing and visualizing abstract theoretical knowledge with experiments, we can better understand theoretical knowledge. For example, the hydrolysis of salt, the amount of substance and so on. Ask more questions, practice more and learn more. Biology is a subject that correctly understands the body and learns the relationship between man and the environment (plants, animals and nature). First, we should carefully understand the content of the textbook, study hard, and connect with various concepts according to the learning objectives of each unit to understand and remember the basic concepts; Pay attention to the exact meaning and basic points of noun concept; Internal connection or coherence of relevant knowledge; Flexible use of basic principles and laws; Practical application of basic theory; Compare daily language with scientific language, and organize memory after understanding; 2. Correctly grasp the meanings of images, tables and photos in teaching materials; Combine what you have learned with real life to understand; Use charts to express content, reorganize and understand. 3. Do the experiment carefully. Master the purpose requirements, material preparation, steps and methods, observation points and their expression-description or drawing of the experiment, and connect the experimental arrangement with the concept to understand. Correctly understand the structure and usage of the microscope, directly observe and understand the characteristics of various organisms, and form the habit of keeping an experimental observation diary. 4. According to the biological knowledge structure, organize learning in different levels: 1. Molecule-cell-organ-system-individual-population-community-ecosystem-biosphere; 2. Physical health: the relationship between the form-structure-function-system of the eight systems of the human body. 5. Make use of biological characteristics to remember in different ways: 1. Associative memory: For example, the structure and function of protein and nucleic acid should be related by structure and function, and by function and structure. Blood vessels, heart, stomach, kidney and other organs, mitochondria, chloroplasts, chromosomes and so on. 2. Image memory: Use intuitive materials to help consolidate memory. 6. Consolidate what you have learned by solving problems; Always sort out the wrong questions and focus on reviewing before the next exam.
