First, students' answers and problems
1. Look at the whole test paper. It's too difficult. Some questions are familiar. They are all problems encountered in the usual study and review exams. It is easy for students to get basic marks, but some students' grades are still not ideal. Failure to examine the problem carefully will lead to mistakes. I didn't develop good study habits at ordinary times.
2, the basic knowledge is not solid, mainly in:
2. 1 multiple choice questions are relatively simple, but they are still unsatisfactory for various reasons. Errors are mainly concentrated in questions 6, 7, 8 and 9. The main reason is that knowledge points are not in place, such as thinking is not comprehensive enough or calculation is not enough.
2.2 The errors in the fill-in-the-blank questions are mainly concentrated in 14, 20 and 2 1 questions. The reason why the accuracy of 2 1 question is low is that students can't interpret the meaning of the question. Comprehensive understanding ability and calculation ability, poor judgment thinking.
Therefore, while grasping the "three basics" teaching, we should focus on the teaching materials and the development of students, and strengthen the cultivation of mathematical thinking ability. Actively implement inquiry learning to stimulate students' thinking and cultivate students' innovative consciousness and ability.
Second, teaching reflection and improvement
1. Optimize the classroom teaching process and strengthen the teaching of concepts and basic knowledge. Although this is a cliche, it is not easy to do it well. Therefore, it is necessary to prepare lessons carefully, prepare teaching materials, students and processes to effectively improve classroom efficiency.
2. The polarization of students' mathematics learning is becoming more and more serious. Give timely care and help to students with learning difficulties, encourage them to actively participate in mathematics learning activities, and try to solve problems in their own way and express their views; We should affirm their small progress in time.
We should patiently guide them to analyze the causes of their mistakes and encourage them to correct them themselves, so as to enhance their interest and confidence in learning mathematics. For students who have spare time to study and have a strong interest in mathematics, we should provide them with enough materials to guide them to read and develop their mathematical talent. Strengthen the communication between teachers and students, and do a good job in cultivating outstanding students, helping middle school students and making up the difference.
3. Guide students to carefully examine questions, analyze specific problems, and try to let students independently reveal the formation and formation process of conclusions. Don't rush to draw conclusions, give students some space and time to think.
4. In the process of solving problems, we should consider problems from different angles, levels and directions. It is necessary to improve students' calculation accuracy, pay more attention to cultivating students' reading ability and understanding ability, and pay attention to logical thinking training. It is necessary to cultivate students' ability of observation, induction and generalization, and improve their ability to deal with emergencies and comprehensively solve problems.
5. Cultivate students' divergent thinking ability, rigor and optimal problem-solving ideas. Pay attention to the calculation of solving problems and the demonstration of reasoning process, so that students can form good problem-solving norms and writing habits. Improve the calculation ability and pay attention to the embodiment and embodiment of mathematical thinking method in the process of solving problems.
6. In teaching, the classroom capacity is large, leaving students less time to think and practice, and students can't really grasp the target requirements. Students need to sum up, think and practice after class.
7. Let students participate in the process of knowledge formation and experience research methods. The formation process of mathematical concepts, theorems, laws and other knowledge often goes through the process of observation, analysis, synthesis, induction, analogy, conjecture and proof. In the process of knowledge formation, it is more important to stimulate the interest in learning and learn the strategies and methods of research than to master the knowledge conclusion itself.
In the exam, there are many examples of being helpless when the situation changes slightly because of rote memorization. Let each student learn mathematics through his own inner experience and active participation.
