First, the analysis test paper has seven major questions, which basically cover all the knowledge points that students learn and reflect the questions that students are most prone to make mistakes. The number of questions is too large and difficult. Many of these knowledge points are repeated assessments, which increases the number of questions. For example: 1, 2, 3, 5 in the blank; 2, 3 of judgment; The five small questions selected are all about the composition of students' logarithm and their mastery of numbers. It doesn't need to appear repeatedly, which is a bit cumbersome and gives people a feeling of being crowded and heavy. In addition, the form of the question is not vivid enough to meet the age characteristics of the first-year students.
Such as multiple choice questions and optional serial numbers. It's boring. It should appear in the form of coloring, checking and drawing circles. Problem solving is also all in the form of words, monotonous, which does not meet the age characteristics of freshmen. In addition, the topic is more difficult, and five questions solve three difficult problems. But on the whole, it can be said that this paper largely reflects the children's learning situation and the teachers' teaching situation.
2. Analyze students
Judging from the overall situation of students' papers, the failure rate of students is around 10%. It should be said that students have a good grasp of what they have learned in this half semester, but we can also see many problems from the test paper, mainly including:
1, hasty calculation
Students' oral arithmetic We have been training students in oral arithmetic from last semester to this semester, but there are still some children who fail in oral arithmetic, mainly because they are careless in calculation, and some mistakenly regard addition as subtraction, or subtraction as addition, which shows that the cultivation of students' habit of writing homework seriously and carefully at ordinary times still needs to be strengthened.
2, the problem of solving the problem of reverse thinking will not be solved.
Because when we first taught our children to solve simple problems last semester, we always guided them to add up the two parts, take them away, remove them, and so on, all of which were calculated by subtraction, so children always habitually used inertial thinking to solve problems when solving reverse thinking problems, such as solving the fourth problem (Lulu sent cards to eight students, each of them 1 card. After delivery, there are still seven cards left in my hand. How many cards did Lului take? Several students wrote: 15-8=7. This concept needs to be revised for a long time in the usual teaching, and combined with specific examples to help students change.
3, the exam is not serious and not careful
For example, there are three conditions and two questions in solving five small questions, and students are required to choose the conditions according to the questions, but some students don't look at the questions carefully or listen to the teacher carefully, which leads to mistakes and loss of points. In addition, it is also caused by students' low literacy and difficulties in examining questions.
4. The roll surface is not neat enough.
The low score rate of test paper shows that the writing quality of students is not good enough, and teachers should pay attention to the cultivation of students' writing habits in peacetime.
Third, the examination situation is analyzed one by one:
(1) Numbers are written directly
Students are basically fine. Only a few students' carelessness or poor intelligence lead to mistakes.
Please fill in this form.
1, 2, 3, 5 Small questions: It's all about the composition and meaning of numbers.
Cause of error: Very few students failed to grasp the meaning and digits of two digits, resulting in losing points.
4 small problem: individual students did not grasp the adjacent number of integer ten.
6 Small problem: 15 is bigger than () 1, and 6 is bigger than () small 8.
Reason for error: the topic is difficult, and some students can't reach their own ideas because of reverse thinking.
7 Small question: Between 55 and 95, the number with the unit of 5 is () () ().
Error: The students didn't pay attention to the range, or didn't pay attention to writing a number with ten digits of five.
8, 9, 10, 1 1, the students are basically fine.
13 angle is in 12 small problem ○ 1 yuan 3 angle,
Reason for error: Individual students can't compare and don't master the rewriting between names and numbers.
14 small problem: 2 yuan can change () sheets 1 angle; () Zhang 2 corners; () Zhang 5 jiao
Cause of error: Because students didn't learn multiplication formula, it was difficult to solve this kind of problem and lost a lot of points.
(3) judge right or wrong.
The number 55, a small problem, has the same meaning as the number 5 in the unit and the number 5 in the tenth place. ()。
Causes of errors: the narrative is boring, students' thinking cannot be extrapolated, and their understanding ability is poor.
4, 5 small questions: the wrong reason, students do not have a good grasp of the concept of a much larger number.
(4) easy to choose.
Cause of error: the topic requires serial number, and the students have never learned English. All the requirements of this question do not meet the age characteristics of students. It would be better to change the form.
(5) The following picture was cut from the above picture and connected one by one.
The students are basically right.
(6), tell the location of all kinds of graphics.
Error: Some students are not clear about the concepts of rows and columns.
(7) Solving problems
Error: 1 is the students' poor understanding ability, so you can't draw inferences.
2. Students are not careful in examining questions and thinking seriously.
Third, the presentation form of the topic is too abstract, which does not meet the age characteristics of students.
Fourth, the topic is difficult to understand, and the text narrative is around the mouth.
Fourth, diagnose teaching according to the test results:
Judging from the scores alone, the students' grades are average, but from the point of view of the number and difficulty of questions, the students' basic knowledge is still very good, and some basic skills have been formed, which shows that the teachers' teaching and students' learning are still in place. However, students' ability to use knowledge flexibly to solve practical problems and their flexible thinking by analogy need to be improved.
Judging from the students' test papers, teachers pay more attention to the teaching of students' basic knowledge and the cultivation of their basic abilities, but not to the cultivation of students' practical innovation ability, mathematical thinking and problem-solving ability. Teachers' teaching methods are basically effective and suitable for different students to get different degrees of development. Teachers can basically keep up with the pace of teaching reform, take students' lifelong development as the starting point of teaching, and constantly improve their teaching level. However, students' answers also reflect some problems, that is, students' ability to take exams and methods of doing problems are not fully mastered, and the writing of numbers is not very standardized.
Verb (abbreviation of verb) efforts and improvement measures:
1, contact with real life, creatively use teaching materials, and improve the effectiveness of teaching.
2. Implement open teaching, dilute mode thinking, and cultivate students' flexibility and openness in thinking. 3. Pay attention to hierarchical teaching, promote overall optimization, and let different students get different degrees of development.
4. Strengthen practical activities, strengthen application awareness, and improve students' mathematical thinking and problem-solving ability.
5. Pay attention to the cultivation of students' good study habits, such as listening carefully, examining questions carefully, answering questions carefully, writing regularly, being diligent in thinking, being willing to learn and asking questions, etc.

1, test paper characteristics: The mid-term test paper of junior one mathematics fully embodies the characteristics of taking textbooks as the main part. The content of the exam shows all the contents of the textbook in the students' papers in a simple way, focusing on examining the students' mathematical ability to learn to live and learn flexibly. Pay attention to the testing of basic knowledge and skills. At the same time, students can fully feel the happiness of "applying what they have learned" in their answers.
In addition, this paper focuses on the development of students. Judging from the scores in the test paper, it is difficult for students to get high marks without good study habits.
2. Question:
(1) Fill in the blanks 12 Students lose more points; The reason for the problem is that students have poor independent reading comprehension ability. Among the numbers filled in, () is the closest to 100. Many students filled in 99, reflecting their lack of ability to understand similar feelings.
(2) The small animals in the queue lost the most points; The scoring rate was 75.2%. Cause of error: Students don't know the location deeply and can't tell right from left.
(3) There are many points lost in the fourth question, and the scoring rates are 68.4% and 75. 1% respectively. Error reason: Students can't read the stem of the question carefully, trying to figure out the meaning of the question carefully, and their awareness of answering questions is not clear enough. The topic let me go to the () plane and the () grid. Some students didn't understand this well, so they made mistakes.
(4) There are fewer errors in calculation questions, and the correct rate is over 90%. The students seem to have a good grasp of simple calculations.
(5) Comprehensive application: 1 the scoring rate of the question is 20. 1%, and the loss rate is yes. Badminton racket 65 yuan, table tennis racket is much cheaper than badminton racket, table tennis racket may be 2 1 yuan, while many students from 80 yuan and 60 yuan chose 60 yuan. It seems that students' estimation ability needs to be improved. The error rate of the fourth question of the application problem is also relatively high, and the analytical ability of students to solve practical problems needs to be trained in the usual teaching.
Improvement measures:
(1) Strengthen students' mastery of basic knowledge, and use classroom teaching and exercises to consolidate students' solid level of basic knowledge.
(2) Strengthen the cultivation of students' ability, especially the cultivation of hands-on analysis and practical application.
(3) Cultivate students' good study habits, including careful examination of questions, timely inspection, careful observation and concrete analysis of specific problems.
Tisso
There are three types of questions in this paper, all of which focus on the training of basic knowledge. The whole paper embodies the concept of "mathematics is life", which allows students to solve various mathematical problems in life with their mathematical knowledge. Generally speaking, 3 1 person took the exam in this edition, with an average score of 94.3. Pass rate100%; The excellent and good rate was 80.6%. Judging from the students' questions, I can work out the first one. Except for a few students' calculation mistakes, few students lost points. I'll fill in the second question. * * * There are 10 minor questions, 1, 2, 4, 6, 7, 8, 9, 10 minor questions are all right. The most mistakes are the third and fifth questions. The reason why the third question is wrong is that students are too careless when counting. So the count is wrong.
Question (3) The fifth small question, only two students in the class did it right, and some of them were unclear, which was related to the carelessness of the students. The third big problem, look at the picture formula. Well done, only a few students didn't look at the picture carefully, so they made mistakes.
For some difficult problems, it reflects that students' ability to analyze problems independently and solve problems flexibly is poor, which has little to do with usual training. In the future teaching, we should grasp the knowledge system of teaching materials, seriously study the new curriculum concept, grasp the combination of knowledge in teaching materials and curriculum reform, let students learn mathematics in life, and actively do a good job in cultivating outstanding students after class. Make up lessons for students in time, find their bright spots, establish their self-confidence and let them catch up as soon as possible.
