In the teaching content of each unit, this textbook is equipped with practical problems and practical activities, and the presentation form is real and interesting.
In addition, three special activities were arranged, namely "Knowledge in Numbers", "Passion Olympics" and "Laws in Numbers", to enable students to comprehensively apply what they have learned to solve practical problems.
(5) sorting and reviewing.
Including review (1), review (2) and general review.
Second, the analysis of learning situation
The fourth-grade students have moved from middle grade to senior grade, and their thinking has also begun to transition from concrete image thinking to abstract thinking. Their understanding of things around them has risen to a higher level than before, and they have been able to understand things and solve problems by inductive methods. Students have already possessed the elementary knowledge of mathematics, which has laid a good foundation for learning this textbook well.
After three years of study, students have basically mastered the learning methods of the first phase of primary school, and the relationship between teachers and students has changed from unfamiliar to familiar. Most students have a good study schedule, like learning mathematics, have a good grasp of what they have learned, and initially learn to use what they have learned to solve practical problems in life. However, students' psychological characteristics and thinking development are inconsistent, which requires teachers to pay more attention to teaching students in accordance with their aptitude while facing all students.
Fourth, teaching measures.
1. Create more learning scenes related to students' real life, boldly let students learn by themselves, solve problems and develop students' personality. Strengthen the education of learning purpose, fully tap the potential of students and give full play to their main role.
2. We should make full use of the connection between old and new knowledge, and link new knowledge points with students' original knowledge system for teaching and learning through knowledge transfer, analogy, comparison and expansion.
3. Stimulate students' interest in learning mathematics, pay attention to cultivating students' awareness and habits of autonomous learning, respect students' individual differences, encourage students to choose their own learning methods, and guide students to learn to learn in practice.
4. Enhance students' practical ability and cultivate students' spatial concept.
5, pay attention to strengthen the connection between mathematics and real life, so that students can solve mathematical problems in life, feel, experience and understand mathematics.
6. Strengthen individual counseling to improve the performance of students with learning difficulties. For example, students with learning difficulties should be more concerned and cared for, and the requirements for homework should be appropriately reduced.
Summary of Mathematics Teaching in Grade 4 of Beijing Normal University Edition 2 After this semester's teaching work, the group leader of this grade has also helped me a lot. He often discussed teaching with me and listened to each other, which also put me on the right track of mathematics teaching soon. A semester is about to pass. Let's talk about the gains and losses in teaching this semester.
First, to be strict with students, we must first be strict with ourselves.
Teachers should set an example by asking students to do what they want, and they should set an example first. Pupils are good at reading samples. He is very concerned about what the teacher does. We often hear students say that "the teacher broke his promise and failed to do what he promised us".
Yes, teachers may neglect their students because of busy work or other reasons, but such things can't happen too often. You should keep your promise and keep your word. Of course, don't relax the requirements for students. The completed homework must be completed within the specified time, and students must not have bad study habits of procrastination.
1. We should further study the theory of education and teaching, update the concept of education and teaching, guide our own practical work, and form a teaching model with our own characteristics as soon as possible through our own continuous efforts.
2, strengthen the education of students' good study habits, so that students can finish their homework in time.
3. Try to create a relaxed and harmonious learning situation for students in classroom teaching, and leave enough time and space for students to explore new knowledge, find problems and solve problems in the process of exploration.
4. For all students, for their all-round development, pay attention to students with learning difficulties, give them corresponding guidance and encouragement, let them find their own mutual aid groups to study in the competition, and encourage them to establish confidence in learning mathematics well. After I used them later, the effect was still very good.
5. Strengthen communication with students, learn about students' learning situation in time in classroom teaching, so as to adjust their teaching behavior in time.
Secondly, I think the classroom can't effectively stimulate students' interest in learning.
Mathematics class itself is a very rigorous science, and there must be no falsehood, no matter what it is. Our problem is that we dare not let students think in class. Some problems need to be studied cooperatively, and then discussed and summarized. We lack enough time and space for students. Because we are worried that if they are allowed to do it, they will talk about unimportant things too freely, which will lead to the failure of teaching tasks.
In fact, the correct way is to give them time and space, so that students can "learn by doing" and "learn by doing", which is also conducive to improving students' enthusiasm for learning. Because I know that children are active by nature and like to "play", sometimes it doesn't prevent students from "playing" math.
Third, strengthen the training of students' computing ability.
1, strengthen oral arithmetic learning.
Through oral arithmetic practice for three minutes before class, let students practice in their favorite way in various forms, and hold a "fast arithmetic hand" competition from time to time to stimulate students' enthusiasm. Improving students' oral arithmetic ability is also a kind of promotion and help for written arithmetic.
2. Strengthen the multiplication and division method of three digits.
Grade three students have learned to multiply and divide into two digits. On the basis of the original knowledge and understanding of the rules, I ask students to strengthen consolidation exercises to prevent students from making calculation mistakes due to carelessness. However, in the process of implementation, it is found that students' computing ability is not good, especially division, and even the multiplication formula of individual students can't.
So in addition to teaching, I let students practice several calculation problems every day. Calculation problems also include simple calculation, and students' progressive calculation ability is even worse, especially multiplication and division.
Fourth, unit testing.
According to the usual test results, I did better in the two units of numeration and multiplication this semester. In the graphic transformation and division unit, students have difficulties in learning and poor test scores. A considerable number of students have poor understanding of spatial graphics and weak spatial imagination. Division operation method and related operation rules are not well mastered.
Verb (abbreviation of verb) problem solving
Application problem has always been a major difficulty for students, but it is even more special for the fourth grade. Most students have a poor understanding of application problems. In view of this situation, I ask students to practice more, think more, ask more questions, and gradually improve their ability to analyze problems from quantity to quality, so that students are no longer afraid of applying problems as before.
Increase practical activities and cultivate students' awareness of mathematics application. Design some activities that are closely related to students' lives and contain mathematical problems. Let students feel, experience and understand mathematics by solving problems in activities, which is also conducive to cultivating students' awareness of discovering mathematical problems from daily life.
Sixth, we have done the following work in cultivating outstanding students and underage students:
Cultivate individual gifted students, give full play to the advantages of gifted students, and make them better. Educate poor students to improve their learning enthusiasm and make them better. According to the requirements of the school, work with purpose, organization and content, consolidate your learning foundation, teach at different levels, and teach according to the different characteristics of students.
1, hierarchical teaching, excellent students focus on improving, poor students focus on consolidating basic knowledge.
2. Teach students learning methods, explore students' potential and stimulate students' interest in learning.
3, often give some thinking exercises and ability-based training, let students think and cultivate their innovative spirit.
4. Use the classroom and recess time for counseling to ensure the learning time and quality. Design some in-depth questions in class to make students think.
5. Always give ideological education to gifted students and talk with poor students to improve their interest in learning.
6, to carry out "one-on-one" activities, let gifted students help poor students, so as to take care of the development of individual poor students.
One semester's teaching has ended, and students' grades have improved, but there are still some problems. However, in the future teaching work, we will continue to work hard with students and achieve greater results.
Summary of Mathematics Teaching in Grade Four of Beijing Normal University Edition 3 This semester, I was fortunate to be a member of the Mathematics Teaching and Research Group. After attending the teaching and research activities, I feel that the teaching and research group is like a big family, warm and harmonious. With the help of my teacher, I successfully opened a "vertical and horizontal parallel" teaching and research class. I benefited a lot from the teaching and evaluation of this course.
I teach fourth-grade mathematics this semester, and the school guidance office trusts me very much. Responsibility urges me to do a good job, and I don't regret it. During the period, I was discouraged, but I had more courage to go forward. A semester is coming to an end, so it is necessary to sum it up.
I. Summary of experience
1, change the way students evaluate.
The traditional evaluation method is a test paper, a score and a comment. It is obviously not comprehensive to evaluate students qualitatively and quantitatively. Now I have set up "eloquence award", "cooperation award", "subject award" and "homework award" in my class, trying to find a simple, operable and multi-faceted method to evaluate students. In addition, I often contact my parents.
2. Not limited to textbooks.
According to the actual situation of students, we should use teaching materials flexibly and reorganize teaching materials appropriately.
3. Introduce childlike interest into the classroom.
Due to the small number of students, it is difficult to organize. If students' favorite fairy tales, stories, riddles and games are introduced into the classroom, their enthusiasm for learning will be greatly stimulated. For example, there are many illustrations in the current textbooks, but they are all dead and can't speak. If teachers give them contents and sounds in class, they can be vividly displayed in front of students, thus arousing students' interest and stimulating their enthusiasm for learning.
Second, lack and confusion.
1. Teaching new textbooks for the first time has a great impact on old ideas. Although I have participated in many trainings and read many books on curriculum reform, I know what to do in theory, but it often changes in practice. Although open-minded, bold to try new teaching methods, but in the classroom organization seems helpless, chaotic, students in the teacher's drive, do everything they can, even the best teaching design can not be implemented.
