I. Basic information of students: There are 82 students in Grade Three, all of whom took the exam with excellent results. The average score of this math final exam is 9 1.5, 80 students passed, the passing rate was 97.6%, 72 students were excellent, and the excellent rate was 87.8%. Score 100, the lowest score 14.
Second, the specific content analysis: the knowledge coverage of the third grade mathematics test paper is complete, and students' mastery of what they have learned and their practical application ability can be examined from many aspects. Generally speaking, this paper focuses on the examination of basic knowledge, with moderate questions, basically no partial questions and problems, flexible questions, and closer to the actual life of students.
There are five major questions in this paper: The first major question: Fill in the blanks. (***28 points) Error rate The third question, "The experimental primary school playground runway is 200 meters per lap. Xiao Ming runs twice a day after arriving at school, which is () meters, and then () meters is 1 km. " Some students filled in "1", and some students filled in "3". Obviously, many students lack life experience. This shows that mathematics is closely related to other life experiences. In the usual mathematics teaching, we must emphasize the connection between mathematics and life and stimulate students' awareness of life. The second big question: multiple choice questions. (*** 10) 5 Two of the questions are about multiplication, and one is about length units. Personally, I think the knowledge coverage of this topic is relatively narrow, and we should also increase the knowledge of perimeter, possibility, reasoning, observation object and so on. The third big problem: calculation. (***26 points) Among them, 1 topic "direct writing" and the second topic "vertical calculation" are classic and moderate in size. The fourth topic: draw a picture (***6 points). This topic focuses on the practical ability of students, and the students have done well. Only item 1 draws a line segment of 5cm and 6mm. Rectangular and square students will of course draw different shapes, which is good. The fifth problem is to solve the problem. (***30 marks) This topic is ***6 small questions, and the knowledge covers multiple problems, score problems, normalization problems and perimeter problems. The questions are general, the difficulty is not great, and the amount of questions is moderate. Among them, the third question is more flexible and difficult, but the questions about perimeter are usually done a lot, and the questions are always the same, and most students are not stumped.
Through this final exam, many problems are reflected: First, students lack the ability to examine questions, and their reading of words is not in place, which leads to mistakes. Secondly, it is careless to cultivate students' good study habits. The title will be copied wrong; Simple verbal calculation will also be wrong; After the calculation, the result will be copied by mistake; The rest will be missed; Wait a minute. Third, students do not have a solid grasp of mathematical concepts, so they should memorize these conceptual things on the basis of understanding. Fourth, students can't analyze problems in combination with reality, and can't make good use of the given information to solve problems. Fifth, passing this test also reflects a very common problem among students, that is, students' ability to examine questions and their habit of checking and calculating are relatively poor.
Third, improvement measures: In view of these problems, I will pay attention to the following points in future teaching:
1. Pay attention to cultivate students' good habits of careful examination and analysis. Read the questions before you get them, understand the known information and requirements, and then study, analyze and answer them. When solving problems, we should also pay attention to the analysis of quantitative relations, so that students not only know how to do it, but also know why to do it.
2. Continue to cultivate students' good study habits, pay attention to quality for 40 minutes, give timely feedback from the last student, make up the difference in time, and make it public. Some basic concepts should be memorized on the basis of students' understanding.
3. Cultivate students' ability to analyze questions. Especially for some problems with long topics and many words, first clear your mind and analyze sentences.
4. We should also strengthen the calculation. Through the actual situation, first understand the calculation law and take various forms to carry out special calculation exercises.
5. Strengthen contact with parents, communicate in time, make joint efforts, and teach according to the different characteristics of students to improve their comprehensive quality.

First, the overall situation This paper covers a relatively comprehensive range, which can examine students' knowledge and practical application ability from many aspects. Generally speaking, this paper focuses on the examination of basic knowledge, with moderate questions, basically no off-topic and difficult problems, flexible questions and close to students' lives. But the students didn't do very well. The excellent rate is only 20%, and the passing rate is 8 1%.
Second, the examination paper analysis
This proposition is divided into seven major questions. The following problems in this test are analyzed one by one:
Question 1: Fill in. (*** 18) 50% of the students made mistakes within 5 points. The eighth question of error rate, "Four small squares with a side length of 5 decimeters are combined into a big square with a circumference of () and an area of ()". Many students have asked about the perimeter and area of the small square, and some are even more outrageous, with an error rate as high as 97.5%. Secondly, the fourth question, "A 36-cm-long iron wire encloses a square, and the area of this square is ()", has different answers. About 90% of the students made mistakes because they didn't master the method, didn't understand that 36 cm was the circumference of a square, and then calculated the side length and area according to the circumference. Again, the second question is unit conversion, with six spaces. Most of them have an error in length unit, area unit and mass unit, and most of them have an error in conversion of area unit, mainly because the work of this piece is different, which is easy to be confused and leads to errors. Thirdly, the fifth question is to fill in the appropriate unit name, and the four spaces are generally wrong. There is a seventh question, "Estimate, the fastest is to draw' ○' in (), and the slowest is to draw' △' in ()". The main reason for the mistake is that I didn't read the requirements carefully.
The second question: judge a sentence. (***5 points) 25% of the students got it right, and the most mistakes were questions 2 and 3: If the side length of a square is three times, its area is three times. Many students did it right without careful thinking. Students can't use the area formula for analysis, and they don't use the example method well. Question 3: When three digits are divided by a non-zero digit, the quotient may be two digits. First, students didn't look at the problem seriously, and second, they didn't seriously think about the difference between "possible" and "yes" here.
Question 3: Choose one (5 points). 10% of the students are fine. The error rate of the fifth question is as high as 75%: a rectangle with a length of 15cm and a width of 8cm is cut into a new square, and the area of the square () is wrong, which is the area of the rectangle directly calculated. Secondly, the problem 1 is a square land with a side length of () meters and an area of 1. Ha. Unexpectedly, 50% of the students chose 1000, and they didn't have a good grasp of this basic knowledge.
Question 4: Calculate (***32 points) 1, and write directly: 75% of the students get full marks, most of the other students make one mistake, and very few make two mistakes.
2, vertical calculation of 50% of the students get full marks. The main causes of errors are carelessness, such as: there is a remainder in the calculation result, the remainder is not written when writing the answer horizontally, the result is not written after calculation, the number is copied incorrectly when writing the result, and the dividend written by the result should be checked. When calculating 750÷3, some of them are equal to 25, indicating that students have not mastered the algorithm of division with 0 at the end of quotient.
3. Out of step, 39% students get full marks, 1/3 students who make mistakes make more than two mistakes. Mainly because the calculation is not careful.
Question 5: Draw the symmetry axis of the graph (***4 points). 93% of the students got full marks. The main reason for the mistake is that there is no painting, and one painting is wrong one after another.
Question 6: Mobile filling (6 points) 27% of the students get full marks, mainly because the number of squares is not good when translating.
Question 7: The correct rate of solving problems (***30 points) 1, 2 and 4 is high, and the reason for individual mistakes is carelessness. Question 3: The main reason for students' mistakes is that the application area of planting 3 Chinese rose flowers per square meter is multiplied by 3 instead of division. There are many mistakes in the fifth question, mainly because it will not be combined with practical analysis to solve the problem. The sixth question is the most, mainly because there is a lot of information in the question and there are many problems to be solved, so students can't choose information well.
Third, through this test, the problems reflected:
(A), students' computing ability is relatively lacking, and they can't follow the order of elementary arithmetic well. Simple addition, subtraction, multiplication and division are also prone to errors.
(2) It is careless to cultivate students' good study habits. The title will be copied wrong; Simple verbal calculation will also be wrong; After the calculation, the result will be copied by mistake; The rest will be missed; Wait a minute.
(3) Students' grasp of mathematical concepts is not solid. For example, they don't know that the square area with a side length of 100 meters is 1 hectare. Let students recite and memorize these conceptual things on the basis of understanding.
(d) Students can't analyze problems with practice, and can't make good use of the given information to solve problems.
(5) Passing this test also reflects a very common problem among students, that is, students' ability to examine questions and their habit of checking and calculating are relatively poor.
Four, the future teaching measures should pay attention to the following points:
(1) Cultivate students' good habit of examining questions, carefully examine questions and carefully analyze them. When you get the topic, browse it first, understand the known conditions and requirements, and then study and analyze the answers. When solving problems, we should also pay attention to the analysis of quantitative relations, so that students not only know how to do it, but also know why to do it.
(2) Some basic concepts should be memorized on the basis of students' understanding.
(3) Cultivate students' ability to analyze topics. Especially for some problems with long topics and many words, we must first sort out our thinking and analyze them carefully.
(4) We should strengthen the calculation, first understand the calculation law through the actual situation, and take various forms to carry out special calculation exercises. To achieve 20 words: strengthen oral calculation, teach correctly, stick to the rules, train in place, and form habits. .
(5) Teaching students in accordance with their aptitude to improve their comprehensive quality.
(6) Further do a good job in preventing poverty and prevent polarization and aging.
In the usual teaching, we should try not to give up any student and let every student meet the most basic requirements, which really requires teachers to pay more efforts, love and patience.
Tisso
First, the basic situation of the test scores: 24 people in the class took part in this test. Excellent number 17, qualified number 23.
Test analysis:
This math test paper has various forms and comprehensive contents, which is in line with students' cognitive level. On the whole, this exam is moderately difficult, focusing on the basics, the content is closely related to the actual life, and it pays attention to fun, practicality and innovation. Highlight the characteristics of the subject, conceive propositions with ability, and embody the spirit of mathematics curriculum standards. It is helpful to inspect the mastery of mathematics foundation and basic skills and to guide and cultivate teaching methods and learning methods.
1, closely related to the textbook, comprehensive and focused.
From the content point of view, the test is what is taught in the textbook, and what students are required to master is not deviated from the textbook at all. Formally, every big test question appears in the textbook and is familiar to students. The whole paper contains the most basic questions, as well as application questions, to cultivate students' problem-solving and comprehensive ability. The content of the exam basically covers what is taught.
2, close to the reality of life, reflecting the application value.
"Everyone learns valuable mathematics" is a basic idea of the new curriculum standard. According to the requirements of the new curriculum standard, this test puts forward the theme from students' familiar life, makes boring knowledge live and situational, and makes students experience and feel the necessity, practicability and application value of learning mathematics knowledge through filling in the blanks, selecting topics and solving problems.
3. Pay attention to the examination of various abilities.
Through different mathematical knowledge carriers, this exam comprehensively examines students' computing ability, observation ability and judgment ability, as well as their ability to comprehensively use knowledge to solve life problems.
Second, the analysis of candidates' answers;
1. Fill in the blanks: This question mainly examines students' mastery of using book knowledge to solve problems in daily life. Many students can't handle problems flexibly according to the knowledge in books. The questions with more mistakes are questions 6 and 8.
2, true or false: this question ***5 small questions, 5 knowledge points. Among them, 2 or 5 small questions made the most mistakes, and the students didn't think seriously.
3. multiple-choice questions: actually, it's very simple. The key is that students don't use their brains and look at the questions carefully, which leads to mistakes in some simple questions. Some students don't quite understand the conceptual knowledge and need the teacher to explain.
4, oral calculation, calculation questions: oral calculation of 8 small questions, estimation of 4 small questions, students make fewer mistakes. With vertical calculation, students learn the calculation method better. The main reasons for the mistakes are: students are not careful in writing and the same numbers are not aligned.
5, integrated into life, ***5 questions, of which the second and third questions are more wrong, and the second question, many students do not understand the meaning of the question, and there are many calculation processes, and the students are not careful; The third question requires students to take a boat. Although some students solved it, they ignored the point that when there are not enough people on the boat, the boat is a boat. It seems that teachers should pay attention to cultivating students' ability to solve problems in real life in future teaching.
Three, in the future teaching, we should pay attention to these aspects to be improved.
1, students' oral calculation and estimation ability needs to be strengthened to improve accuracy.
2. In teaching, consciously train and improve students' thinking ability.
3. In teaching, improve students' ability to solve problems by using mathematical knowledge.
4. In view of students' poor ability of analysis and understanding, students should be trained to think from many aspects and angles in the future application teaching, so as to apply what they have learned. Educate them to use what they have learned flexibly to solve practical problems in life.
5. Teach students in accordance with their aptitude and improve their comprehensive quality.
