There are 4 1 students in Class Two, Grade Four. Judging from students' study habits and learning ability, children have improved on the original basis. In the usual study, the vast majority of children can take the initiative to learn, and their homework can be completed seriously and independently on time. It is not difficult to see that students have a certain ability of self-management and restraint, whether they look at the class schedule, extracurricular activities after class or the time of arriving at school in the morning and afternoon. These good habits have a certain influence on children's autonomous learning and exploration, thus promoting the improvement of students' learning ability and learning enthusiasm. But looking at the students' situation, we also found some problems: some underachievers need timely counseling. Due to the differences between students, some students lag behind other students in their studies, which is the distress of students and the worry of teachers. Underachievers are often caused by many reasons, such as poor study habits, not serious study, family influence, children's own quality and so on. Therefore, this semester, we should further carefully analyze the causes of underachievers, formulate corresponding transformation measures, solve problems in a targeted manner, and adopt follow-up, group cooperation, peer assistance, timely counseling and other methods to improve different children at different stages and in different aspects.

Verb (abbreviation of verb) teaching measures
1. Strive to create a democratic and harmonious learning atmosphere for students, so that students can truly become the masters of learning and stimulate their interest in learning mathematics. Continue to strengthen the cultivation of study schedule and study habits, such as the habit of attending classes, finishing homework on time, reviewing after class before class, carefully examining questions and standardizing writing format. Cultivate students' serious and responsible learning attitude and good habits of careful calculation and inspection in the learning process.
In view of the fact that some students in our class don't like doing homework, in the process of homework inspection, we mainly adopt the "division of labor responsibility system" and divide each large group into three groups. The team leader checks the homework of the team members twice a day, and the team leader is responsible for supervising and supplementing the unfinished homework. The group leader's homework will be supervised by the monitor and the study committee, and students with high quality homework will be rewarded, while students with late homework or low quality homework will be criticized and educated. If you fail to meet the requirements for more than three times, let the cadres in each class have a clear division of labor, strengthen supervision, and have clear rewards and punishments to prevent students from forming the habit of defaulting on homework.
2. Pay attention to the training of basic knowledge and skills, control the amount of training and grasp the training density to achieve the best training effect. Pay attention to improving students' computing ability, pay more attention to refinement and practice, and take effective measures to solve existing problems in time to ensure the improvement of classroom teaching efficiency.
In view of the poor computing ability of the students in this class, each student will be required to complete one page of oral arithmetic exercise every day this semester. For students with poor written calculation ability, they will complete three written calculation exercises every day, which will be corrected by their parents to improve their calculation ability. There is a written test once a week. In addition, there is a class ten-minute oral arithmetic contest and a class written arithmetic check contest this semester.
3. Strengthen problem-solving teaching. In the problem-solving teaching of this textbook, the problems are all formed by adding a condition or changing the problems in the two-step calculation application problems that have been learned. In the teaching process, we should pay attention to cultivating students' ability to discover equal relations and cultivate students' ability to analyze and solve practical problems by creating situations. Arrange an article on math diary every week, so that students can observe the mathematical problems around them by remembering math diary, learn to look at some practical problems from a mathematical point of view, and improve students' problem-solving ability.
4. Pay more attention to students' individual differences, respect students' creative spirit and pay attention to the problems students encounter in the learning process. Timely and effective help and guidance should be provided.
5. Communicate with students more, understand their inner world, help students solve various problems in the process of study and life in time, untie the knot in their hearts, and let them feel the fun of learning in a happy and relaxed atmosphere. Appreciate every tiny progress of students at every level, encourage, praise and affirm in time, criticize more, increase their self-confidence in learning and let them feel the happiness brought by learning.
6, pay special attention to the training and make-up work.
(A) Training measures for outstanding students
1, protect the enthusiasm of outstanding students and encourage questioning.
2. Infiltrate extracurricular knowledge in teaching, guide students to study by themselves, and guide students in a planned way after class.
(B) Underachievers counseling measures
1, cultivate the self-confidence of underachievers. Be tolerant of underachievers and blame them less. Be sincere, caring and patient with underachievers.
2. Not only should we pay attention to cultivating underachievers' interest in learning, but more importantly, we should pay attention to cultivating the stability and concentration of their interest, so that underachievers can have perseverance, concentrate on their studies, strive for perfection, seek pleasure from boredom and seek happiness from difficulties.
3, the teacher's counseling should be timely, and the classroom design should be suitable for the problems of underachievers, giving them more opportunities and timely counseling, so that they can experience the joy of success.
4. Underachievers' homework should be corrected in person, and the existing problems should be corrected in time.
5. Carry out "one-on-one" pairing activities.
6. Contact many schools, communicate with parents and communicate information to promote the progress of underachievers.
Sixth, the teaching experiment project plan: how to improve students' computing ability.
(A) the proposal of the topic
Computing ability is a basic mathematical ability and an important basis for learning mathematics and other disciplines. It is an important task to cultivate primary school students with certain computing ability. In primary school teaching, computing teaching runs through the whole curriculum and occupies a considerable proportion in the whole textbook. It is of great practical significance to cultivate students' computing ability. Whether in life or in production, calculation plays a vital role. However, with the development of electronic technology, calculators and computers have entered thousands of households, but students' computing ability has declined. Therefore, how to improve students' computing ability has become an important research topic in primary school mathematics teaching.
(B) the development of training objectives
1. Correct students' learning attitude and cultivate students' good habits of calculation and writing.
2. Cultivate students' calculation accuracy and speed.
3. Let students improve their computing ability in a relaxed and pleasant learning atmosphere.
(III) Main measures
1, fully understand the importance of cultivating computing ability.
Numbers and calculations are the basis for students to learn other mathematical knowledge and even other disciplines. In addition, numbers and calculations are also widely used in daily life, work and study. Therefore, in computing teaching, we should pay attention to creating problem situations, combining computing with life and production practice, and infiltrating with other related disciplines, so that students can deeply understand the importance of computing ability and correct their learning attitude.
2. Pay attention to the cultivation of estimation ability.
Strengthening estimation can promote the development of students' sense of numbers, which plays an important role in calculation teaching, and helps students to find their own deviations in solving problems in time, rethink and calculate, thus preventing and reducing mistakes and improving calculation ability. In addition, in the four operations, if students memorize some commonly used data, such as: 4 χ 25 = 100,
125 χ 8 = 1000, etc. , can better master the calculation skills and help students achieve the requirements of "correct, rapid, reasonable and flexible" in calculation ability.
3. Create various calculation exercises.
Calculation problems are composed of numbers and abstract operation symbols, which makes students easily fidgety and bored. Therefore, teachers should adopt a variety of teaching methods, enrich learning activities, stimulate students' interest in doing calculation problems, thus promoting the correctness of calculation and improving students' calculation ability. For example, games such as driving a train, turning a turntable and finding friends can stimulate students' interest; Treating young trees, you can correct my mistakes by doing it, which can reduce students' mistakes; Small challenges, group competitions and other forms of competition can improve students' computing speed.
