1. Generally speaking, students have a good grasp of basic knowledge, but they are not flexible enough.
In particular, questions 5 and 9 of the fill-in-the-blank questions require pi to be calculated by 3. Because students are too skilled, "pi is usually calculated by 3. 14", and it is calculated directly without looking at the questions, which leads to the correct method and wrong answer. From this phenomenon, we can not only see that students are not careful when doing problems, but also show that students do not understand mathematical concepts thoroughly enough, which is also the deficiency in my usual teaching.
2. Students' ability to solve practical problems by using basic knowledge of mathematics has been greatly improved, but the ability of middle and lower grade students is obviously insufficient.
Especially the second problem of operation, "A cone with a base diameter of 5 decimeters and a height of 12 decimeters is known. Please draw a cylinder with the same volume. " Because it is the teaching content of the last twelve volumes, such exercises are not practiced much in teaching, and students still don't have a thorough grasp. The error rate of this question is also very high.
Where improvements are needed:
1, continue to strengthen the teaching of basic knowledge. Continue to implement the spirit of curriculum reform in teaching and arouse students' initiative and enthusiasm in learning.
Strengthen the teaching of mathematical concepts, especially let students feel and improve themselves. Strengthen calculation teaching and cultivate students' calculation ability.
2. Strengthen the close connection between mathematics knowledge and real life, so that students can use what they have learned to solve practical problems and cultivate their practical ability.
This is the weakest place for students, and it is also the place that needs to be improved most.
