Analysis of Mathematics Test Paper at the End of the Sixth Grade Volume I (1) Surface Analysis of Test Paper
In this examination, the examination paper examines students' thinking and problem-solving ability from three aspects: concept, calculation and application, and comprehensively examines students' comprehensive learning ability. The test questions are impartial, not difficult and unfamiliar. They are closely related to students' real life, which increases their flexibility, tests their real grades and levels, and enhances their interest and confidence in learning and using mathematics.
Second, the questions reflected in the test paper mainly include:
The first big question: fill in the blanks. This topic consists of 12 small questions, covering a wide range, comprehensive in content and typical. It comprehensively examines students' mastery of basic knowledge, the formation of basic skills and their flexible application ability of mathematical knowledge in textbooks. Most students can get full marks, but the main individual students who make mistakes have not fully grasped the concept of scores.
The second big problem: judgment. This question includes five small questions, 1, 2, 3 and 5, which show that students have mastered and applied basic knowledge well, and some students have made mistakes because they have not carefully examined the questions.
The third big problem: choice. ***5 small questions, this question is relatively easy, and the fourth small question, some students are easy to read the wrong question and make mistakes.
The fourth big problem: calculation. The correct rate of direct writing is high, reaching about 95%. However, some students are not serious in the calculation process of simple algorithms, and there are not many mistakes in solving equations. Most students have mastered the basic calculation, but they are careless and not serious in the process of doing it.
The fifth question: operation. This topic is to examine students' understanding ability and link it with real life, and to cultivate students' observation ability and life application ability. The students made a serious mistake on this issue. The third question, the students did not carefully examine the question, and most of them misunderstood it.
The sixth question: solve the problem. There are five minor problems with this question. Solving problems is the highlight of the math exam. The students did a good job on this problem, but some students made mistakes in the calculation.
Third, the analysis of students' papers:
1, the mastery of basic knowledge and the formation of basic skills are better.
2. The comprehensive application ability of knowledge is weak. Students fill in the blanks and apply problems, mainly because they have no deep experience of new knowledge during the learning process, and the concepts established in their minds are unclear and unstable.
3. Did not form good study habits. A slightly more complicated problem-solving will have a certain impact on some students with weak ability or poor habits. For example, many simple calculation errors, missing questions and other low-level mistakes on paper.
Fourth, the direction of efforts:
1. In teaching, we should not only base ourselves on textbooks, but also closely connect with life, so that students can learn more about mathematics in life and solve problems in life with mathematics.
2. train students? Apply what you have learned? Knowledge, the level of flexible application.
3. Pay attention to cultivating students' good study methods and habits. Such as: the habit of independent thinking, the habit of reading and examining questions carefully, and so on.
Analysis of the Final Examination Paper of Mathematics in Volume I of Grade Six (II) This Final Examination Paper of Mathematics in Grade Six is divided into nine parts: filling in the blanks, judging, choosing, calculating, looking at pictures to find relationships, doing it by hands, counting in life, practical application and additional questions. Through analysis, I found that this set of papers has three characteristics:
1, while examining students' basic knowledge and skills, it pays attention to the examination of students' comprehensive ability, which fully embodies the purpose of quality education.
2. Paying attention to the assessment of students' two-way thinking is conducive to the flexibility and creative development of students' thinking.
3. Pay attention to the examination of the ability of system analysis and solving practical problems, so that students can fully realize the importance of applying what they have learned.
On the whole, this final exam shows that some students have mastered the basic operation and knowledge well, learned more solidly and calculated more accurately.
Most students answered this question well, and the most wrong topic was (3). Most students can calculate correctly, but they don't write the name of the unit completely. The correct rate of this question is only 35. The main reasons for the mistakes are as follows: First, the exercises arranged in the textbook are in the form of filling in the form of filling in the results directly, which weakens the writing consciousness of the company name; Second, in the test questions? Is the average height recorded as 0? Students mistakenly think that they don't have to write answers.
The correct rate of this question is high, and some students make mistakes because they didn't do well in the exam.
The error rate of this question is low, and a few students (4) make mistakes in the results because of their lack of reasoning ability.
There are many mistakes in writing (3) directly, and all the students who make mistakes are equal to 1. The main reason is that they ignore the calculation order and are eager to achieve success, which leads to mistakes.
The correct rate of most questions in this question is very high, and a few students make mistakes in calculation. The main reasons are: first, students make mistakes in calculation, and second, they ignore the requirements of the questions, which should be calculated in normal order and simplified, resulting in the loss of the whole question.
(5) Look at the picture to find the relationship, (6) Do it by hand, and (7) Calculate in life.
The answers to these three questions are ideal, students can draw and analyze statistical charts accurately, and their hands-on ability has been fully used in the questions.
(viii) Practical application
This set of questions can fully examine students' ability of analysis, judgment, synthesis and reasoning. Among them, the questions 1, 4 and 5 were answered well.
Although the problem-solving theory is not complicated, the conditions are flexible, students lack the ability to solve problems in combination with reality, and students' thinking ability is shallow, which leads to some students' understanding deviation and falling into an intellectual trap. Students have shallow thinking ability, lack flexibility in thinking, ask unclear questions, and fail to understand what they are seeking. There are still some students who can't calculate accurately and can only regret it.
The answers to the three questions can not only test students' intelligence, but also reflect their comprehensive ability to use knowledge. It is the place where this set of questions makes the most mistakes. My analysis of the reasons for this phenomenon is as follows: Among the problems,
Knowledge points are not difficult to understand, but students cannot accurately express the quantitative relationship with line segments. Some students use three lines to express the problem they want, that is, they lack the means to solve the problem.
In short, the test paper basically reflects the real level of students, and the four grades of excellent, good, medium and poor reflect the comprehensive ability of students, which shows that the test paper is objective and reasonable. Through the analysis of the examination paper, we can also see the successes and shortcomings in our teaching work, and make clear the direction of improvement and improvement in the future. First of all, on the premise of a solid foundation, we should broaden students' knowledge; Secondly, we should pay attention to the cultivation of students' two-way thinking and multi-direction thinking in order to improve the flexibility and creativity of students' thinking; Third, we should pay attention to the connections and differences between knowledge, cultivate students' ability to draw inferences from others and learn ten things at a time, so that students can learn and use them flexibly.
I (3) 1 Analysis of the Final Mathematics Examination Paper in the first volume of Grade Six. Overall situation: the reference number of this test is 18, the reference rate is 100%, the average score is 83.94, the excellent rate is 50%, and the pass rate is 100%. The test paper is divided into six parts, with a full score of 108. The highest score of students in the class is 100, and the lowest score is 62. The overall difficulty of the test paper is not great, but it is flexible and changeable, involving many knowledge points, and it is not easy to get high marks.
Second, the answer:
The first question, fill in the blanks, out of 20, the score is about 15, and the fourth question has a higher score. The ratio of the number of cattle and sheep in the animal farm is 3: 5. It can be said that the number of sheep is () times that of cattle? This kind of topic has been practiced many times before the exam, assuming that three cows and five sheep are enough, and many students take the data backwards; Question 7? Draw the largest circle in a square. What is the ratio of the area of this circle to the area of this square? This question examines the inner circle of the foreign party, but no data is given. The child has ideas in his heart and can't get the data. Because this kind of topic is slightly more difficult, in order to encourage students to relax their requirements, write? The calculation results of 4, 157: 200 and 3. 14: 4 are all given points, which is very good to remember. I am glad that three students in this class have written the standard answer of 157: 200. Question 8? When doing math problems, Xiao Ming divides a number by 2/3 and operates according to multiplication. The result is 6 and the correct result is ()? I thought I would lose a lot of points, but the students answered very well. It can be seen that the students have a good grasp of the calculation of fractional multiplication and division.
The second question, judgment, out of 5 points, the score is about 3 points. I feel that the difficulty is very small, but there are few full marks and many points lost 1 question? When a nonzero number is divided by a true fraction, the quotient must be greater than the original number? Some students think too complicated. Question 3? The radius of the circle increased from 3cm to 4cm, and the area increased by 3. 14cm2? Individual students have made mistakes in understanding;
The third question, choice, out of 6 points, got about 3 points, this question lost more points. In the second sub-question, the students' travel map shows that the children made mistakes when observing the coordinates. Option A has no vertical scale, option B does not start from zero, and option D is upside down, resulting in more students losing points. Question 4? A rope, after cutting 1/3, still has 1/2 meters left. Some students didn't find the original length of this rope.
The fourth question, calculation, is out of 33 points. Because each question is correctly applied 1 point, it is out of 35 points, with an average score of about 26 points. The most lost points are to find the shadow area, one is a square plus a semicircle, and the other is a semicircle. In the first calculation, many students did not change diameter 6 into radius, and in the second calculation, they did not divide the area of the ring by 2. In the final analysis, they did not skillfully use the formula and did not carefully examine the questions.
The fifth question, problem solving, out of 36 points, covers fractional multiplication, the application of ratio, fractional division, the circumference and area of a circle, and the work unit? 1? Knowledge points such as questions, locations and directions are difficult, and the score is about 25 points. Question 1: Which page should I read on the third day? Many students did not add 1 on the basis of Grade One and Grade Two, but calculated by subtraction, resulting in losing points; Question 2? Iodine wine used for disinfection is made by mixing iodine and wine at the ratio of 1: 50. Now there is 50g iodine. There are 8 students who can make this iodine solution, and the rest have lost points to varying degrees, or the unit has not changed, or only the water quality is not iodized, or only the quality of iodine is counted. Question 5? There is an oil drum, which is filled with half a barrel of oil, 60% of which is removed and poured into 10 kg. At this time, there is as much oil in the bucket as before. How many kilograms of oil can this barrel hold? Many children interpret the score of 10 kg as 1-60%, which leads to calculation errors.
Additional questions, out of 6 points, about 4 points, not difficult. It's a question of the inside of the outer circle. It needs children to understand that a square is divided into two right-angled triangles along the diagonal. The bottom of the triangle is the diameter of the circle and the height is the radius of the circle. To be sure, it is calculated by the triangle area formula, and some students can directly use the formula deduced from textbooks.
Third, in view of the existing problems and future efforts:
1, to further consolidate students' computing ability, including oral calculation, estimation, off-line calculation, solving equations, finding the area of shadow part, etc. In this test, many excellent students are equally divided in solving equations, finding the area of a circle and even writing directly. Therefore, this kind of strengthening and attaching importance to cultivating this ability is worthy of my reflection in future teaching;
2. Check the problem carefully. Through repeated emphasis and exam training, students have certain inspection habits, but there are still many phenomena of losing points because of carelessness in the exam, such as: fill in the blanks, question 6? Draw a circle with a compass with a diameter of 20 cm. The distance between two feet of a compass is (), and the circumference of a circle is ()? This is a very simple topic, but many students have lost their units, which is a pity;
3. Be sure to always focus on the teaching materials and refine the questions. Textbooks are the basis of teaching, and any important exam is transformed from textbooks. Therefore, in the future teaching, it is very important to screen test questions and do less extra work.
4. Broaden students' thinking and cultivate their independent thinking ability. Try to stimulate students' interest in learning, build students' confidence, broaden students' divergent thinking, make students think hard and think more, give full play to the advantages of study groups, and cultivate students' thinking ability in a pleasant atmosphere.
