Before reviewing, I carefully studied and discussed the mathematics curriculum standards and notes of the senior high school entrance examination, made a detailed analysis of the examination questions in the past three years, and made some thoughts on making plans, examples, exercise selection, writing examination questions, promoting at different levels, and allocating classroom time. Make a review plan according to the actual situation of our school, and tell the students about the plan, and give them a positive psychological hint-review is planned and measured, and it will be successfully completed. We divide the review into four stages:
(a), the first round of review, review section.
The time is roughly set from March to mid-April, about 7 weeks. The purpose is to make students master the basic knowledge of junior high school mathematics, improve their basic skills, master basic methods, and form a knowledge network comprehensively, solidly and systematically, which is the focus of the general review.
Mainly adopted the following strategies:
1, printed and distributed "Notes for Senior High School Entrance Examination"
The test center requirements and sample questions in "Notes for Senior High School Entrance Examination" are printed and distributed to each student, so that students can review according to the test center requirements, which has strong pertinence and good effect.
2, section review
"Petunia should lead it by the nose", grasp the key points, focus on the textbooks and review the sections. According to the knowledge system of junior high school mathematics, all the contents of junior high school are summarized into the following 10 sections: number and formula, equation (group) and inequality (group), function and its image, statistics and probability, line segment (angle) and triangle, quadrilateral, graphic transformation (figure and coordinate), congruence and similarity, right triangle and circle. It takes about 36 class hours. In the plate review, tell the students the approximate proportion of each plate in the senior high school entrance examination. The selection of examples and exercises is mainly based on the textbook, and the typical examples and exercises in the textbook are adapted and trained. In each knowledge block, some practical application questions and dynamic exploration questions should be infiltrated, which not only improves students' interest, but also reduces the difficulty and burden of the second round of review.
3. Synchronous detection
In close contact with the test center of our unit, based on the notes of the senior high school entrance examination, taking the questions of the past three years as the theme, we select targeted and typical questions for analysis and testing, and pay attention to cultivating students' ideas and methods of learning to solve problems. Each version of the fast synchronization test pays attention to the connection before and after. This unit accounts for 70%, and other units focus on 30%. Volume a 100, volume b 20, 60 minutes. The examination time is usually arranged for self-study in the evening.
Step 4 calculate every day
Errors in calculation greatly affect students' grades, thus undermining their confidence in learning mathematics. At this stage, special attention should be paid to improving students' computing ability. To this end, we add a calculation problem to our homework every day.
5. Teach review methods
The acquisition of review methods will benefit students for life. Ask students to sort out the review content before the teacher reviews it, and teach students the methods of sorting out, such as reviewing the properties and judgments of various quadrilateral and trigonometric functions. Review the related properties, numbers and formulas of circles in the outline; Compare and review multiplication and factorization of algebraic expressions; Review how to solve equations and inequalities by analogy.
At this stage, special attention should be paid to coordinating the use of extracurricular review time in other disciplines to avoid the phenomenon of loose front and tight back.
(2) The second round of review: special review: comprehensively apply knowledge and strengthen ability training.
The time is roughly set at the end of April-mid-May, about 3 weeks. The purpose of review is to improve students' analytical ability and problem-solving ability, which is the extension and improvement of the first round of review.
Mainly adopt the following review strategies:
1, special review, issued in advance.
According to the test paper structure of Luzhou in recent years, eight topics have been determined: filling in the blank, basic operation, basic proof, chart information, reading innovation, solving right triangle, circle and finale. Organize examples and exercises and discuss trade-offs. All special cases and exercises are sent to students one day in advance, so students can answer independently first, which also plays a preview role. When using, it should be noted that each of the first five topics has a class time, and each of the last three topics has no less than two classes, especially the finale. A good class can have four classes.
According to the characteristics of the examination papers of senior high school entrance examinations over the years, we should pay attention to the following topics in special training: application questions; Highlight the development of science and technology and the transformation of information resources; Reading comprehension questions reflecting self-study ability test; Graphic change questions and open questions examine students' adaptability; Induce conjectures and operational inquiry questions to examine students' thinking ability and innovative consciousness; The key basic content of high school learning.
2. One question a day
In order to improve students' problem-solving ability, a topic that is slightly more difficult than the review content (equivalent to the problem-solving difficulty of volume B) is given every day, which is required for upper middle school students to do, and middle and lower middle school students choose to do. Due to the tight time, the classroom comments are not true, so the teacher posts the answers in class, and the students compare and correct them after class. At the same time, the teachers' answers also gave students a good demonstration. Training one question a day is also of great benefit to students' self-confidence.
(3) The third round of review: simulation training to improve test-taking skills.
The time is about two weeks from mid-May to early June. The key point is to strengthen problem-solving guidance, train students' problem-solving strategies, and improve students' comprehensive problem-solving ability and test-taking ability.
The strategy adopted is to select and adapt the test questions from the test papers issued by cities and counties and the test questions of senior high school entrance examinations in various places, and make 2-4 sets of simulated test questions according to the test questions structure, scores and difficulty ratio in recent years. The answer time is generally 120 minutes, which is 30 minutes less than the examination time to train students to solve problems quickly. Pay attention to the whole grade to take the exam at the same time to prevent students from missing questions. In this round of review, you can also print out the original volume of the senior high school entrance examination in the past three years and send it to students for extracurricular practice.
(4) the fourth round of review: review the aftertaste, so as to achieve three "overviews" and one "no drilling"
One week before the middle school entrance examination, return the class time to the students, guide them to go back and review their textbooks, and use the classroom to browse math books at least once; Fault problem set; Go through all the papers in the review stage. At the same time, the problems existing in students' exercises are sorted into aftertaste exercises. So as to consolidate the knowledge points and improve the actual combat ability. At this stage, students must be asked not to delve into deep-seated problems and problems.
Schools with loose time can refer to this timetable. Schools with tight time suggest that the simulation training and thematic training can be compressed a little or the method of "clearing in one spoonful" can be adopted, and the thematic training and simulation training can be included in the section review. No matter how you review, the key is to implement it. Although time is tight, don't tell the students so as not to cause too much psychological pressure.
Second, strengthen teaching and research and give full play to group advantages.
Because the evaluation mechanism plays an important guiding role, the school adopts double complete sets of calculations (subjects and classes are a whole respectively) when formulating the evaluation scheme, which makes the preparation group have to unite and cooperate to fight the whole war. Our preparation team has done the following work:
(1) Insist on preparing lessons collectively. We spend half a day preparing lessons collectively every week. Prepare key points, test sites and difficulties, and prepare teaching methods and learning methods. Discuss the detailed explanation requirements of typical examples, summarize the problem-solving skills, and check whether each test question is appropriate in unit synchronization.
(two), adhere to the activities of listening to each other's lectures and evaluating classes, and promote the improvement of teachers and students.
(3) Concentrate on the requirements of reviewing lessons and papers, and do a good job in each lesson.
Review the to-do list in class:
1, define the review objectives and form a knowledge system; Typical case analysis is in place, and typical cases should have comprehensive and representative problem-solving ideas, methods and skills. These exercises should be carefully selected, refined and evaluated.
2, realize the four modernizations
(1) Basic concepts and theorem exercises
(2) systematization of knowledge structure
For example, the quadrilateral knowledge learned in junior high school is easy to be confused in nature and judgment, which can guide students to sum up the main knowledge they have learned and form a "quadrilateral structure diagram"
(3) Hierarchical training method
Students of the famous mathematician Chen Shengshen asked him: Do you study mathematics? His answer is to learn mathematical thinking methods. During the training, we designed some training modules, such as "basic training", "improvement training", "innovative training", "direct entrance examination" or "challenging entrance examination", to train effectively from easy to difficult. Through training, students can master the mathematical thinking methods and mathematical models commonly used in junior high school. Mathematical thinking methods include: classified discussion, transformation, transformation, combination of numbers and shapes, elimination, reduction, disproof, image, formula, substitution, undetermined coefficient and overall thought. Mathematical models include sum of numbers, equations (groups), inequalities (groups), functions, geometric figures and statistical probability models.
(4) Innovation of problems
In recent years, there are many questions to test students' innovative ability, which should be done in review.
(1) Carefully design questions and give students the opportunity to innovate.
The problem is the core of thinking. Only by asking questions with certain depth can students be aroused to think positively. For example, when ants eat honey, what is the shortest distance from a vertex on the surface of a cube with a side length of 20cm to the farthest vertex? How to solve the problem of turning a conditional "cube" into a cuboid with the same length and width and different heights? The length, width and height are different. How to solve it?
(2) Provide enough time to give students opportunities for innovation.
After asking questions, students must be given time to think independently. Sometimes the questions asked by our teachers are more difficult, for fear that students will not think of them, so they will rush to remind them. In fact, such a reminder is a great interference to students' thinking.
(3) Give students room for free activities.
Innovation needs time and more space. After the question is given, the teacher should try not to patrol below and interfere with the students' analysis.
Pay attention to leave at least 10 minutes at the end of each class for students to review and practice independently.
In a word, no matter how to attend the review class, the key is whether it is student-oriented. Pay attention to students' participation state (first, observe whether all students are involved in learning, second, see whether some students are still involved in teaching, and integrate the roles of teaching and learning), communication state (see whether there are multilateral and diverse information contacts and feedback in the classroom, second, see whether there is a good cooperative atmosphere in classroom interpersonal communication) and thinking state (see whether students dare to ask questions and express their opinions, and second, see whether the questions and opinions are challenging and original). ), emotional state (whether students have a moderate sense of tension and pleasure, and whether students can control and adjust their learning emotions. ), the state of effectiveness (see if the students have done their best and learned something, and feel practical and satisfied; Second, see if students are more confident and relaxed in the follow-up study.
In the review, there are many lectures about examination papers. In order to improve the efficiency of lectures, examination papers should be given as follows:
1, analyze the test paper and understand the obstacles.
Teachers should first analyze the gains and losses of test papers, focusing on the causes of errors and understanding the difficulties and obstacles of students' learning.
2. Send papers in advance and conduct "finding points" training.
Give students papers half a day in advance, let students analyze and correct them themselves, and carry out "finding marks" training, so that students can realize the harm of carelessness in exams, and at the same time, "finding marks" can build students' confidence.
3. Classify comments and acquire skills.
Comments can be divided into problems, knowledge and solutions; It is necessary to comment on the answering skills of various types of questions, such as how much to write, how to score, how to score steps, and even how to score from the marking teacher.
4, "clearly marked", clearly checked wrong.
When students are evaluating classes, they should be clear about the grading standards and common means of finding mistakes to avoid losing points due to negligence. For example, I forgot to check when solving problems, and I forgot to bring my unit.
5. Guide students to sort out the wrong problem sets.
Third, several problems that should be paid attention to in review
1, for all students to review.
Our school is a branch of Lu Xian No.2 Middle School, and the diversion work is very difficult. I'm sorry to say that grade 07 shunt work got 0, and most of them survived. Facing this reality, the only way to comprehensively improve the teaching quality and face all students is to carry out teaching work at different levels and promote it by classification. Specific practices:
(1) Hierarchical requirements: Our school is divided into two classes, the reform experimental class and the English experimental class. The progress of the two classes is unified, and the examination questions are unified, but the class requirements are different. The reform of experimental classes requires less capacity and depth. In the review of each class, the strategy of "low starting point, more induction and quick feedback" is adopted for the underachievers in the class; For intermediate students, strict and serious problem solving is required, so that they will not lose points in regular problems; For top students, they are required to take shortcuts, be creative and keep improving.
(2) Improve training: Make a 16 list of improve training combined with the review content every week, send it to students who are willing to do it every Monday, and check it next Monday. Only when it is finished can you get the next one. Through practice, the effect is obvious.
(3) Group Counseling: Group students with poor foundation, use self-study time for counseling every week, and try to revise the homework.
2. Scientific use of extracurricular materials
Teachers should have more than four kinds of materials, and must learn to integrate and use them. To make students jump out of the ocean of problems, teachers must jump into the ocean of problems. Write exercise groups with selected materials, focusing on the knowledge that students have not mastered. Students should have similar materials for homework, and teachers should boldly delete the repeated training topics that students have mastered or the syllabus does not require students to master. It is important to note that students' homework time should be controlled within 30 minutes every day.
3. Pay attention to reviewing psychological training and answering skills training.
A philosopher said, "Your mentality is your real master." Mentality determines success or failure.
The first is to adjust the mentality psychologically, not only for students, but also for teachers. When reviewing the senior high school entrance examination, avoid the teacher's excessive tension and bring too much pressure to the students.
Most schools are short of psychological teachers. We can download the lectures on exam-oriented psychological training online and post them in the classroom, and give students review psychological guidance and exam-oriented psychological training according to the actual situation of our school. To avoid students' fear of the exam, candidates should take the questions they did wrong in the exam and the questions they don't understand and don't understand as opportunities to exercise themselves again, correctly analyze the reasons, and the more problems they find before the exam, the luckier they are, the more timely they are, and the faster they will improve. In the exam, if you can't afford to do the really difficult questions, such as the last question, you will "reluctantly give up what you love" and ensure that you will do it foolproof. I have to comfort myself. There are still 95 points out of 5. 95 points is a high score.
Third, we should avoid the "plateau phenomenon" of review efficiency; Avoid only talking about the general situation and not writing about the specific "tongue tip phenomenon"; Self-righteous and omniscient "saturation phenomenon"; It is necessary to cultivate the "Valenda mentality". Valenda is a famous American tightrope walker. In an important performance, he unfortunately slipped and died. His wife said afterwards, I know something must happen this time, because he always kept saying before he took office that this time is too important to fail. However, in every successful performance before, he only thought about the tightrope itself and ignored everything it might bring. Later, people called the mentality of concentrating on doing things without losing money "Valenda mentality".
Fourth, review and relax training before the exam to relieve tension.
4. Pay attention to "four more and four less" in the review.
Encourage more and criticize less. More guidance and less indoctrination. More discussion, less explanation. More simple, easy and new, less complicated, difficult and old.
Mathematics review in grade three is short in time, heavy in task and demanding. The above methods are very rough. Because of the time, any good methods are all collective wisdom, which can play a role in attracting jade, and it is my greatest expectation. I hope everyone can combine the reality of our school, grasp the outline, make a reasonable and scientific review plan, lay a solid foundation, improve students' problem-solving ability, cultivate students' good test mentality and easily meet the test.
