How to review senior three mathematics effectively under the new curriculum standard.
In the review class, it is of great significance to face the new curriculum reform under the new situation: in the face of this new "college entrance examination rule", people are concerned about whether the future college entrance examination mathematics questions are relatively stable or full of changes. Is it to keep the traditional style or to further transition to the new curriculum? How to embody and consolidate the achievements of educational reform? As a senior three teacher and student, how to study and review effectively and keep pace with the times? I think we should consider the following aspects: First, we should fully understand the characteristics of the new curriculum reform concept. The characteristics of mathematics textbooks under the concept of new curriculum standard are that they should not only reflect the foundation, times, typicality and acceptability, but also have affinity, questions, thoughts and connections. The change of presentation mode of teaching materials promotes the change of learning mode, so we should also start from the following aspects in the review process: 1, emphasizing background, thinking and application. We should not only attach importance to the background of knowledge and law discovery, but also restore the process of mathematical knowledge and concept discovery, so that students can feel that the development of knowledge is natural, natural and cordial; Instead of imposing it on others. We should grasp the core mathematical concepts and important mathematical thinking methods in a spiral way; Grasp the essence of mathematics and ensure its scientificity; Emphasis on mathematical thinking and reasoning training. By solving the problems of real background, students are guided to gradually understand the role and strength of mathematics in the current society, as well as the direction of development and application. 2. Emphasize problems and inspiration, and guide the change of teaching and learning methods. Follow the cognitive law, guide learning with questions, reflect the process of mathematics knowledge and students' cognition, urge students to explore actively, and cultivate students' innovative consciousness and application consciousness. In the review of senior three, students' inner vitality and passion can be fully mobilized, so that students' thinking flexibility, divergence and creativity can be fully brought into play, and the review effect will be more obvious and effective. Teaching AIDS can only suppress students' personality, wisdom, imagination and creativity, while "teaching freedom" can fully mobilize students' inner vitality and give full play to students' flexibility, divergence and creativity, which will produce unexpected results. 3. Emphasize the foundation, attach importance to general methods, and downplay special skills. Adhere to the "three basics" and lay a solid foundation for students' lifelong development. The exam notes clearly point out that the proportion of easy, medium and difficult questions is controlled at about 3: 5: 2, that is, the middle and low-grade questions account for about 80% of the total score, which determines that we must grasp the foundation and persevere in the college entrance examination review. Only when the foundation is laid and the concept is clear, the middle and low-grade questions will be handy, and the thinking will be clear and the operation will be accurate when dealing with difficult comprehensive questions. Orientation of new content: basic and acceptable, reflecting and consolidating the achievements of educational reform. Treatment of the original content: reform the teaching requirements and treatment methods, focusing on inheriting the advantages of traditional textbooks, pruning and adding leaves. 4. Strengthen contact and highlight the guidance of mathematical thinking methods. Understand the application of mathematical science knowledge in life, production and scientific and technological development. Be able to correctly use general mathematical thinking methods to analyze and solve problems. Second, we should have the general idea of reviewing and preparing for the college entrance examination under the new curriculum concept: accurately grasp the teaching requirements and step by step. Under the new curriculum standard, the main purpose of mathematics review is not only to enable students to consolidate and deepen their understanding of the learning content stipulated in the new curriculum standard, but also to cultivate and improve various abilities, especially to enable students to reach a new height in exploration, practice and innovation. To do this, we should do: 1 in review, instead of "walking fast, looking back more, reflecting more and gaining more" in one step. It is basic and important for periodical libraries to classify and query periodical articles, and try to use "inductive formula" to let students experience the generalization process of concepts and the formation process of thinking methods. "2. Pay more attention to the exploration of core concepts and mathematical laws. Construct a knowledge system with prominent main lines and reasonable structure. The teaching materials of each module are developed around a certain main line, and the presentation order of knowledge content is determined according to students' cognitive rules, forming a reasonable knowledge system. To "understand" teaching materials in various ways and improve the efficiency of classroom learning. The main knowledge such as function, vector, probability, solid geometry and analytic geometry is still the focus of the proposition, but the examination questions may shift from the examination of a single knowledge point to the comprehensive examination of multiple knowledge points. When reviewing, we should pay attention to the knowledge connection between compulsory and elective textbooks, but pay attention to the difficulty of elective parts, such as linear regression parts. 3. On the basis of laying a solid foundation, pay attention to the cultivation of ability, and be comprehensive and meticulous, so that students can build a new knowledge network in the process of applying knowledge and discover the internal vertical and horizontal connections between various knowledge points. Grasp the intersection of related knowledge, cultivate the ability of knowledge transformation and migration, extract and process information, cultivate the understanding of mathematics and improve the scientific literacy of mathematics. Advocate the cultivation of inquiry ability, pay attention to the knowledge points required by the examination syllabus, omit the parts that are not required in the mathematics examination syllabus, don't cover everything, and don't add the contents deleted from the new textbook at will, such as plural parts. Third, the college entrance examination preparation strategy under the new curriculum concept: 1. Let the students know the requirements, scope and key points of the college entrance examination. Today's college entrance examination questions have changed from "knowledge view" to "ability view", striving to embody the concept of new curriculum in ordinary high schools, the overall requirements of mathematics curriculum standards, paying attention to the examination of mathematics literacy and ability, paying attention to the times and practicality, and promoting the implementation of quality education. It is necessary to deeply analyze the distribution of test sites and scores in several provinces that have entered the new curriculum reform in the past three years, and it can be concluded that the contents of the college entrance examination in the past three years are basically stable, and many contents have been tested for two or even three consecutive years. But the score proportion of each module is important, the main knowledge; Important ways of thinking are still the focus. Multiple choice questions, fill-in-the-blank questions and solution questions can be classified and combined with training methods. 2. Correctly grasp the direction of college entrance examination review: With the implementation of the new curriculum, a standard textbook with multiple versions has emerged. In teaching, we study the textbook carefully and master the basic knowledge of the textbook according to the textbook version, exam outline and explanation used by students. Therefore, in order to grasp the direction of mathematics review in college entrance examination, it is necessary to study the examination instructions carefully and make clear the nature, requirements and proposition direction of mathematics problems in college entrance examination. Learning the national examination syllabus, the examination instructions of this province, the teaching requirements of this province and the teaching suggestions of this province is conducive to grasping the key and difficult points of teaching and review, aiming at the direction of college entrance examination, strengthening training, truly implementing teaching tasks and improving the teaching and review effect. 3. Review should focus on science and efficiency: focusing on science mainly refers to the scientific construction of knowledge system, the scientific planning of review at various stages and the scientific training in the implementation of college entrance examination review. The review of basic knowledge should be understood and grasped at multiple levels and angles; At the same time, we should classify knowledge, build a knowledge network, grasp the relationship between knowledge and improve students' basic skills. 4. Pay attention to production and life, reflect the new curriculum concept in connection with the actual test questions, closely connect with the actual production and life, human health and environmental protection, which is full of the flavor of the times and is often reflected in the college entrance examination questions in recent years. The ability to analyze and solve practical problems by using the knowledge learned. To improve the application ability and innovation ability, the new curriculum concept of "paying attention to the connection with real life" has more topics. Because the proposition background of this kind of test questions comes from the actual production, it is convenient to comprehensively examine the relevant knowledge of mathematics, and it can also make students feel that life is knowledge. By paying attention to life, it can guide students to establish a correct outlook on life and cultivate a good lifestyle. 5, give full play to the role of teachers' personality charm in preparing for the college entrance examination: (1), in order to let students learn mathematics well, we must first give students confidence, but how can we give students confidence? First of all, teachers should be dedicated and have a serious and responsible attitude. In addition, we must be proficient in business, have a strong teaching level and have a high ability to control the classroom. Let students know that learning from you can improve their grades, and students can convince you from the heart, so your review work can often achieve twice the result with half the effort. (2) To guide students to make a review plan, we should systematically sort out what we have learned according to their actual level and situation, find out the weak links and dig their roots. If there is any problem in knowledge understanding, we should read the textbook repeatedly, understand the context of the concept word by word, and deeply understand the analytical thinking, problem-solving methods and connotation extension of the textbook exercises. If you have problems with your study attitude and study habits, you should look for those non-intellectual factors that interfere with you, find out the main contradictions and secondary contradictions, and rule them out one by one. If there is a problem with the method of solving problems, we must carefully select the exercises, strive to be precise and concise, and understand the ways and methods of solving problems, so that we can draw inferences from one example to another. (3) Pay attention to the cultivation of psychological quality and improve the ability to take exams. The psychological quality of students has a great influence on the preparation and improvisation of college entrance examination. Especially in the liberal arts mathematics exam, multiple-choice questions are arranged at the end of the whole volume. Through psychological counseling, students can reduce excessive anxiety, eliminate distractions, lighten their psychological burden, establish their beliefs, and answer every question seriously, meticulously and meticulously, which is conducive to improving the results of college entrance examination.
