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, there are not many such exercises in teaching, and students have not mastered them thoroughly. The error rate of this question is also very high.
The knowledge coverage of this test paper is complete, covering all the knowledge points of this textbook. Students' knowledge and practical application ability can be examined from many aspects. On paper, the test questions can be roughly divided into three parts. The first part is the basic knowledge, with 66 points. Including fill-in-the-blank, oral calculation, pen calculation, off-line calculation, column calculation and judgment. Choose several types of multiple-choice questions, including 20 points for fill-in-the-blank questions, 36 points for calculation questions, 5 points for judgment and 5 points for selection.
4. The second part is comprehensive application. The sentence contains two kinds of songs: hands-on operation and problem solving, with a score of 34. The third part is an additional question, accounting for 20 points. Judging from the test questions, the difficulty of the test questions is moderate and flexible, and students' ability to understand the test questions and grasp the body is not strong. So on the whole, the students didn't do very well. The excellent rate was only 1.37%, and the passing rate was only 58.90%.
5. Students don't master the basic knowledge very well, and they are careless in doing problems, so they can't guarantee the correct rate of calculation, and their calculation ability needs to be improved. Some students don't know the operation order in offline calculation, and some students can't list the comprehensive formulas in calculation. Some students list comprehensive formulas, but don't write off-line calculation process, which loses a lot of points. From the problem of drawing vertical lines on the sidewalk, it can be seen that students have poor flexibility in using spatial and graphic knowledge.
