Senior high school chemistry review plan

Part 1: The essay review plan for the senior high school entrance examination

I. Review plan
The review plan is generally a three-stage review method. which is:
The first stage is a chapter review. According to the order of chapters written in the textbooks, different small units are divided according to the content of each chapter for review. This phase will end on April 20th, about 8-9 weeks.
The second stage is a special review. According to the knowledge system written in the textbook, different knowledge topics are designed and reviewed according to different knowledge topics. This phase will end on May 20th, about 5-6 weeks.
The third stage is the simulation test. According to the format and standard of the middle test questions, design the test for the test, and carry out the training for the test. This phase will be completed by June 5th and will last for about 2 weeks.
Second, review strategy
(1) Review of chapters - a longitudinal review based on the textbook.
This is the basic review stage, which is the basic part of the review of the senior high school entrance examination, which determines whether the quality of teaching can be improved on a large scale. Chapter review should be based on the understanding of the basic knowledge, help the principle of improving the quality of teaching on a large scale, reduce the focus of teaching, and comprehensively review the basic knowledge for all students. Through chapter review, it is necessary to achieve accurate memory, thorough understanding and flexible application. Its guiding ideology is: basic, comprehensive, systematic and solid.
1 basis. That is, based on the foundation. First, based on the textbooks, it is necessary to review the textbook chapters from front to back, showing the progressive process of knowledge from easy to difficult, so that students can further understand the formation process of knowledge and further understand the knowledge in the cognitive process of revisiting knowledge. Connotation and extension, so that students' understanding can further enhance the analysis and application ability in the new cycle. Second, based on the outline, according to the basic requirements of the syllabus, more than 80% of the students can master the standard, design corresponding review or training content for each knowledge point, do not blindly raise the height or design difficult test questions, so as not to affect the students' review enthusiasm. .
2 comprehensive. That is, comprehensive coverage. First, in terms of breadth, it is necessary not only to find every knowledge point in the textbook, but also to miss any knowledge points, but also to pay attention to the links before and after the knowledge points, as well as the presentation and examination angles in the actual application. Detailed variation training; second, in depth, we must carefully analyze the outline and test descriptions, and clarify the basic requirements for each knowledge point examination. In addition, we must analyze the actual examination level of each knowledge point against the middle examination questions, and adapt to the mining or expanding knowledge. Connotation, according to the basic requirements and the actual design of the corresponding examination depth.
3 systems. That is to establish a system. First, it is necessary to establish a knowledge system, to summarize and sort out the unit knowledge points, to find out the relationship between each other, and the knowledge points related to this unit, which can break the textbook chapters, continuously integrate and contrast, and make students form better and better. The second is to form a method system. The examination of knowledge points is presented through exercises. In the process of knowledge combing or exercise training, it is necessary to continuously extract knowledge rules and problem solving methods, so that students can master the methods of constructing knowledge and master the law of knowledge existence. Master the ideas or methods for solving problems and form a complete system of knowledge and methods.
4 solid. That is to do a good job of implementation. First, grasping the implementation of knowledge, the basic knowledge must not only be memorized accurately, understand thoroughly, accurately grasp the connotation and extension, but also be able to skillfully analyze or apply; second, grasp the implementation of training, and strengthen the correspondence or variant of knowledge. Sexual training, through training, enables students to understand knowledge from multiple angles, grasp the examination methods from multiple angles, master the problem-solving ideas or methods, and improve the ability to analyze and solve practical problems.
(2) Special review - horizontal review based on knowledge points
This is the comprehensive review stage, which is the key link in the review of the senior high school entrance examination, which determines whether the quality of teaching can be greatly improved. The topic review should be based on the principle of conducive to consolidating the foundation, improving the comprehensive ability, strengthening the connection and contrast between knowledge, strengthening the integration and application of knowledge, and improving students' ability to comprehensively analyze and apply. Its guiding ideology is: consolidation, improvement, integration and improvement.
1 consolidation. That is to strengthen the foundation. The topic is the horizontal classification of textbook knowledge. In the process of knowledge classification, each knowledge point still needs to be involved. The degree of understanding of each knowledge point will inevitably affect the understanding of knowledge relationship and affect the effect of topic review. It is necessary to promote students' understanding of the basic knowledge through the analysis and contrast of design knowledge points.
2 perfect. That is to perfect the system. The first is to sort out the relationship. The topic is a kind of knowledge. It is a knowledge system that summarizes the related knowledge from the perspective of the overall textbook. The knowledge system is widely distributed and the relationship is not clear. The classification process is not knowledge. Simple listing, but the re-combination of knowledge, not only has a clear classification standard or classification basis, but also a clear combination relationship, therefore, through the combination of knowledge, students will further understand the organizational standards and organizational relationships of knowledge, so that The formation of a special network with specific content and a combination of relationships. In addition, each topic is not independent, and there is a certain integration between the topics. In the process of combing the topic knowledge, it is necessary not only to strengthen the knowledge within the topic, but also to strengthen the relationship between the topics, so that the entire textbook knowledge can Form a more systematic knowledge network. The second is to improve understanding. In the first round of review, the knowledge points are relatively small, the knowledge connotation is not fully explored, and the knowledge understanding still remains on the surface. Therefore, on the original basis, further expand and extend the knowledge connotation and knowledge. Into the background of the topical knowledge, let students further understand the connotation and extension of knowledge in a new perspective or height, and improve the degree of knowledge.

Chapter 2:

In order to effectively improve the pass rate and excellent rate of the government and reduce the low score rate in this year's senior high school entrance examination, the school's chemical preparation team has developed the following review work plan to help students make progress and breakthrough in the final stage. painting:
First, in the beginning of March and mid-April, the first round of review will be carried out. The unit will be integrated with the theme for review, and the problems exposed by the students during the review process will be investigated and leaked. The knowledge points will be consolidated to lay the foundation for the next round of review. Classroom teaching has clear teaching objectives and content arrangements, and it is necessary to highlight the foundation and strengthen the basic knowledge. In the classroom, we use the students to summarize knowledge points, the teacher induction system, and to test in the form of unit exercises and small dictation after class. For the current situation of parallel students in our school, we have the most basic requirements for the more difficult and abstract four, five, nine, ten, and eleven units, and give confidence to students through the first, second, third, and twelfth units. Mobilize student enthusiasm. We strengthen the study of the effectiveness of the work, ensure that there are exercises in the classroom, the teachers in the group allocate two to three units of basic knowledge points, and supplemented with the corresponding exercises, one per unit, in the classroom, do the class Receive, timely approval, targeted and timely evaluation. And to ensure that students at different levels after the class have homework to do. The amount of homework or practice should be appropriate, and the assignments or exercises should be arranged with corrections and comments. In addition, teachers should care for each student, do not easily give up any one student, respect and trust the students, win the trust and love of the students with the true feelings, make the students happy to learn, and the teachers also teach.
Second, mid-April-May-May, the second round of review, combined with block review and chapter review, is divided into four parts: basic concepts and principles, elements and compounds, chemical experiments, chemical calculations; In the process of “elements and compounds”, the chapters are again combined to strengthen and consolidate. In this round of review, in order to cultivate students' ability to summarize and self-review, teachers are properly guided; using selected middle-level exam questions and a small number of comprehensive questions to assess the improvement of students' comprehensive ability after review, and timely make recommendations for students at different levels. Corresponding adjustments and processing.
3. From mid-May to the end of the year, conduct comprehensive test questions and test papers in recent years, and combine the recent trends of the senior high school entrance examinations to conduct a series of special review questions such as information questions and ability inquiry questions. According to the situation, timely analysis, timely trapping, improve students' ability to test and hotspot analysis, so that they can learn the balanced processing of all parts of knowledge to improve the excellent rate of our school; for some temporary undergraduates, let them firmly grasp the basic knowledge The understanding and application of the knowledge and basic concepts, grasp the basic points in the Chinese test paper, and comprehensively improve the average score and pass rate of our school.

Chapter three:

In the current year, our school's chemistry started on the basis of the second day of the second grade. From the beginning of spring, it entered the review stage. In the process of reviewing, how to let students grasp the knowledge system of chemistry in the whole country, accurately grasp and flexibly use various knowledge points, form a strong ability to analyze and solve problems, how to grasp content and time, time and efficiency, and sort out knowledge and The relationship between innovation ability, etc., based on the course standard and exam description, the review plan is as follows:
First, the guiding ideology
The new chemistry curriculum standard states: "The chemistry curriculum should highlight basic, universal and developmental, making chemistry education accessible to all students and achieving a valuable chemistry for everyone; everyone can acquire the necessary chemical knowledge; different People have different developments in chemistry." Therefore, the chemistry review should be aimed at all students. It is necessary to make all levels of students have a better grasp of the basic knowledge, basic skills and basic ideological methods of the country, and to make as many students as possible to form a good thinking quality and strong Comprehensive ability, innovation awareness and practical ability.
Second, the basic principles
1. Adhere to the whole nature. The review period is short and the task is heavy. At this stage, we must handle the relationship between the whole and the part, pay attention to the foundation, and start from the last one to achieve a high rise.
2. Emphasize the comprehensiveness of the review. Carefully sort out the knowledge system, distinguish the key points, allocate the time reasonably, pay attention to the penetration of knowledge, and use the point to match the line to help students build a complete knowledge system.
3. Focus on planning. Develop a detailed plan, and deal with the three stages, the classroom and practice, the foundation and ability, the foundation and the innovation in the review stage, step by step, step by step.
4. Focus on improving ability. On the basis of systematic review, we attach importance to students' ability to analyze and solve problems, explore sexual ability, and expand students' thinking space.
Third, analyze the test sites and clarify the review ideas.
The first stage: chapter review, a total of nine weeks and 54 class hours.
According to the textbooks, we will review the knowledge points and conduct a longitudinal review to build a unit knowledge network diagram. In recent years, many questions in the exam questions originated from textbooks. Prototypes can be found in textbooks. Some of them are processing, combining, extending and expanding textbook prototypes. Therefore, it is necessary to closely follow the textbooks and lay a solid foundation in reviewing. This is the basic review stage. It is the basic link in the review of the senior high school entrance examination. Review should be aimed at all students and reduce the focus of teaching. Through chapter review, the memory is accurate, the understanding is thorough, and the flexibility is applied. Keep a record of the nature and use of common substances. Especially the common chemical equations. At this stage, we must have three good customs: memory, basic methods, and basic skills.
The second phase, the topic review, totals 24 lessons per week.
Review should focus on the key points, firmly grasp the basic knowledge, and carry out knowledge networking, systematization, deepen understanding, and strengthen memory. Students are required to pay attention to those who repeatedly mention and re-emphasize the repeated presentations and tutorials in the textbooks. At the same time, the memory method is summarized and the memory ability is cultivated. During the review process at this stage, the teacher follows the principle of intensively speaking and doing a good job of speaking-practicing-combination. It is necessary to teach students to solve problems and help students understand the connection between the topic and the topic. At the same time, it also strengthens the training for the middle school entrance examination questions, so that students can use it flexibly in answering questions, and they can be used as a reference. When doing the questions, ask the students to mark the questions they don't, and the different mistakes should be represented by different symbols. After discovering the problem, return to the textbook in time to find the corresponding knowledge points and strengthen the memory understanding. This stage is the key link in the review of the senior high school entrance examination. Through review, the problem-solving ability is effectively improved.
The third stage, comprehensive training, a total of three weeks and 18 hours.
At this stage, the focus is on improving students' comprehensive problem-solving skills. Train students' problem-solving strategies, strengthen problem-solving guidance, and improve test-taking skills. The practice is: select certain questions from the test questions collected by the city, county, and school, and splicing into high-quality test questions for comprehensive training. Each test requires students to complete independently, and the teachers promptly correct and emphasize. At the same time, it breaks through the inference questions, and explores comprehensive questions such as experiments and calculations. Investigate the lack of traps, through self-improvement, master the ability to do comprehensive questions, improve the accuracy, flexibility, and standardization of problem solving. Improve the resilience of the exam.
The fourth stage: return to the textbook, a total of 6 lessons a week.
One week before the senior high school entrance examination, all the time is given to the students, so that they can look back at the comprehensive stage and the wrong questions in the previous questions, find the problem and the corresponding knowledge points on the textbook, and finally clear the blind spots.
Fourth, review methods and measures
1. Learn the curriculum and syllabus, and make a unified understanding.
Seriously study the spirit of the curriculum standard, the syllabus and the provincial senior high school entrance examination seminar, sort out the knowledge points, and grasp the quasi-sense. What should be made for students to understand, what should be flexible for students, and which aspects should be integrated and improved. Teachers should be aware of the content and requirements of the review, so that they can control the whole process of review and improve the quality of review.
2. Strengthen teaching research and give play to group advantages.
Adhere to the collective preparation of lessons, focus on the key units and key sections of knowledge, to accurately grasp the knowledge points and test sites.
Concentrate on collective wisdom, carefully compile and simulate the test questions, strengthen the review content, learn from each other's strengths, and improve together. In each review stage, the person in charge is responsible for the topic, collective discussion, revision, finalization and release, to select the test questions, so that students are freed from the sea of ​​questions.
Exploring the mode of review class, to the quality of the classroom
3. Deal with the relationship between class and extracurricular, speaking and practicing
In the classroom, we must pay attention to the comprehensive and systematic knowledge, facing all students. Pay attention to highlighting basic knowledge and basic abilities, and guiding students to improve their thinking and analysis methods. It is forbidden to talk about the generation of students, to practice the school, and to ignore the low. Extracurricular exercises should be carefully designed. It is necessary to digest the knowledge and methods learned. It is necessary to leave room for thinking, so that students can improve their understanding and improvement of knowledge and methods in practice, and the amount of exercises is moderate.
4. Strengthen communication with students and establish a good relationship between teachers and students. Fully mobilize the initiative and enthusiasm of students, individual counseling for students with difficulties, pay attention to psychological training, reduce the psychological burden of students before the exam, so that students can play the best level.
In short, the content of junior high school chemistry review is extensive and has a lot of knowledge. Through review, students can master the knowledge points learned by the middle school chemistry, form basic skills, improve problem-solving skills and problem-solving skills. I believe that through the joint efforts of all the teachers in our chemical group, we will achieve excellent results in the 2019 exam.

Chapter 4:

For the third-year students, with the release of the final exam scores in each district and the last winter vacation, the time for self-study can be said to be gone. How to plan and implement the spring study of chemistry in such a tough situation? Let's share with you the experience of combining the previous third year and the spring study plan of 2019.
First, the new course solution and acid-base salt of the learning solution and the acid-base salt part are the concentrated sources of difficulties in the chemistry discipline of our whole country. Therefore, it is always the requirement of this stage to study this part of the new course completely and precipitate it. Although this part of the new class will be closed at the end of March, we can't completely digest it in the corresponding time period, which will lead to the students not being able to use it effectively after learning, so in the follow-up review, the solution And acid and alkali salts should be intensively practiced as a key content.
Second, complete the first round and the second round of review for the first round of review:
Pass the memory off. It is necessary to remember and remember all the formulas, natures, uses, etc. If the students want to test better schools, such as the National People's Congress, the Fourth Middle School, the Tsinghua University, and the 101st, they must add extra relative atomic mass and simplification. After the solubility table is also back, without accurate memory, there is no good result.
The basic method is off. For example, the intersection method writes the chemical formula, the parity method balances the chemical equation, determines whether the metathesis reaction can occur, and the like. After the basic calculation: the proportional method to find the proportion or mass fraction of the elements in the chemical formula, the total mass method to find the solute mass fraction of the solution, etc., this part must not be lost.
Pass the basic skills off. For example, if you give a question, you find its solution method, that is, know what method to use, then you have the ability to understand the problem. Do it for each question to know its test sites. The basic purpose: systematization of knowledge, practice specialization.
Second round review:
The first round of review is mainly to sort out the knowledge points in the order of textbooks, and to carry out longitudinal review, so that candidates can build a complete knowledge framework in their minds. In the second round of review, it became a comprehensive review of the topic, requiring candidates to connect knowledge points in tandem and form clear problem-solving ideas in their minds. Because the distance between the senior high school entrance examination is very close, the candidates should seek to improve on the basis of maintaining stable performance.
The second round of review calls for a strong focus and a solid grasp. On the basis of summarizing the teaching materials and grasping the basic knowledge, the requirements are raised accordingly, the system is sorted and digested, the key points are grasped, the understanding is deepened, and the memory is strengthened. Students are required to pay attention to those who repeatedly mention and re-emphasize the repeated presentations and tutorials in the textbooks. At the same time, the memory method is summarized and the memory ability is cultivated.
The second round of review is directly related to the effect of the senior high school entrance examination. This requires teachers to prevent simple repetition during the review process at this stage, and to oppose all aspects, but to follow the principle of intensive and comprehensive, to achieve a combination of - training - evaluation. It is necessary to teach students to solve problems and help students understand the connection between the topic and the topic. At the same time, it also strengthens the training for the middle school entrance examination questions, so that students can use it flexibly in answering questions, and they can be used as a reference.
Although the second round is a special review, but the time is already very tight, candidates can not simply do special exercises, to improve their ability to integrate knowledge through comprehensive questions. At this time, there is no need for candidates to find their own questions. It is enough to do the exercises specified by the teacher. When doing the test papers, the candidates should mark the questions that they would not, and the different errors should be represented by different symbols. After discovering the problem, return to the textbook to find the corresponding knowledge point in time, and then mark it out after the solution to enhance your sense of accomplishment.
Third, attacking inferential, exploratory experiments, calculations and other comprehensive problems I believe that many teachers have encountered such situations in class: calculation questions and inference questions, no matter how difficult it is, students only need to be light and frown. Directly on the two words "No!" In fact, we must change the interest of students, build confidence through simple questions, and gradually pass the physical characteristics through the students' summary and reaction to simple questions. The familiarity of chemistry, from the direct relationship between the reaction relationship and the reaction relationship, to the final use of the material when the proficiency is used, so that the inference problem is small, but the problem of students' minds still needs to be different. Type of questions to complete.
The calculation problem is nothing more than an analysis process. Whether it is data analysis or unknown transformation, it is to analyze the required result from the known. It is nothing more than the difference method to find the gas and then transform it into the specific problem in the equation; the other is to find The mass of a substance in the solution is divided by the total mass of the solution after the reaction, and the mass fraction of the solute is determined. Generally speaking, an equation problem usually has one or two traps inside. The two equations need to be summed or evaluated after the solution is completed. This requires the students to understand the problem.
In April-May, these difficult questions will be solved. In the remaining days, there will be no big mistakes in the 20% problem. Solve these problems. One of the three essential links for chemistry pursuit It is the most crucial one.

Chapter 5:

In 2019, the senior high school entrance examination is about to come. In order to help more ninth grade students to better cope with the chemistry exam, the reporter specially interviewed the chemistry teachers of the University of Education. The teachers have carefully studied and developed the next two for the students. Mid-month review plan.
First: return to the textbook and get through the concept.
In the ninth grade chemistry textbook of 2012, new reforms have appeared. The knowledge chapters in the textbooks of the ninth grade have changed. The third chapter first learns the knowledge of material composition. The fourth chapter learns the water in nature, which is more in line with the students. The cognitive law of knowledge. During the review process, students should return to the textbooks, sort out the knowledge points and basic concepts in the textbooks, and further modify and improve some of the concepts in the new textbooks. This requires students to be more careful in the process of learning. The concept must be understood word by word. For example, in a textbook, a molecule is defined as "a substance composed of molecules, a molecule is one that retains its chemical properties."
During the teaching process, many students only remember that the molecule is the one that keeps the particles with the least chemical properties, so that mistakes occur frequently in later learning. The reason is very simple. Everyone ignores the basic particles that make up the substance, including the molecules. , ions, so the chemical properties of those composed of ions are not maintained by molecules. Therefore, I hope that in the last two months, the students will be able to calm down and study the textbooks carefully to understand the textbook knowledge.
Second: Strengthen the understanding of chemical terms.
In chemistry, there are many proper nouns, such as molecules, atoms, ions, chemical formulas, valences, relative atomic masses, elemental symbols, chemical reaction equations, etc. These are the most important tools for learning chemistry. Students are confused when they first come into contact with these terms, and they are prone to the mistakes of Zhang Guan Li Dai. Therefore, in the later studies, students should link these chemical terms with specific chemical substances, find the connections, and deepen their understanding of the meaning of chemical terms.
Third: pay attention to the knowledge of elemental compounds.
The ninth grade students are unskilled in the writing of chemical reaction equations, and even in the writing of basic chemical formulas, the valence is not proficient, which directly leads to equation errors. In the ninth grade of chemistry, everyone systematically studied the knowledge of carbon and carbon oxides, metal and metal materials, acid-base salts and other basic elemental compounds, and involved more knowledge points. Students felt that they could not Good grasp of the key points. Students are advised to read through the textbooks, use the experiments set in the textbooks, open the catalogue during the review, and use the way of independent recall to understand the internal connections between the knowledge points in each chapter, so that the knowledge is systematic.
Fourth: strengthen experimental learning.
Chemistry is an experiment-based science. In the ninth grade textbooks, many simple and interesting experiments are designed. On these aspects, students can intuitively acquire basic knowledge and operational skills. On the other hand, they can train students to observe and Experiments are especially important for the ability to explore independently. Students should learn to summarize in the review, for example, in the preparation of carbon dioxide, in the form of experimental inquiry, to cultivate students' ability to design experiments independently. You can link the methods of gas preparation you've learned in the ninth grade to find ways to design and collect devices when making general gases.
Fifth: pay attention to social hotspots.
Chemistry is a science that is very practical and practical. It is closely related to reality. Chemical knowledge is infiltrated in all aspects of real life. Learning to use, linking the learning textbook knowledge to real life is a basic application, so students should pay special attention to the relevant social hot issues in the textbook, such as the problem of air pollution, the basic method of water purification principle, greenhouse effect, acid rain Hazard and so on. It is possible to combine the basic theoretical knowledge of textbook learning with relevant solutions to solve practical problems.
Finally, I hope that the students will know each other in the process of reviewing. In the process of practicing, they can carefully analyze the intent of the questioner and find out what the basic test sites are, so that they can use the knowledge they have learned to solve the exercises. After completing the exercises, you should learn to summarize, find out your weak links, and strengthen them in time. Carefully add your heart, deepen your memory on the basis of understanding, and learn to apply. I believe everyone can achieve good results in the final exam!
