1. Analysis of academic situation: There are 40 senior two students this semester, and their final grades last semester were not very good. Most students study hard, finish their homework on time and listen carefully in class. However, some students are not serious in class and are prone to small moves, which leads to poor academic performance. There are very few students who study well in this class, and most of them are poor in self-motivation, so they lack self-motivation in learning. This semester, we should pay attention to the guidance of methods, establish correct learning goals and develop good study habits.
Second, the teaching objectives

2. Eugenics: design interesting learning materials and activity scenes for children in teaching to stimulate students' strong interest and motivation. Try to choose and design realistic and open learning activities, so that they can think independently and communicate with each other through activities and understand the meaning of mathematical knowledge. By observing the operation, discussing and communicating, and exploring ways to solve problems, we will provide them with sufficient creative and exploration space and release their creative potential.
3. Training for poor students: Based on students' experience, provide students with familiar life scenes and help them understand mathematical concepts. Through a large number of rich activities such as observation, operation and games. Enrich students' perceptual knowledge. Pay attention to finding and asking simple questions from life. We should fully respect students' ideas, encourage them to think independently, express their opinions, communicate with others to make them interested, consciously participate in learning, and experience the joy of participating in learning and achieving success.

Situation analysis: 45 sophomores. After a year of mathematics study, their basic knowledge and skills have been greatly improved, and they have a certain understanding of mathematics study. Hands-on operation and language expression have been greatly improved, and the awareness of cooperation and mutual assistance has also been significantly enhanced, but there is a clear gap between students. Because this is the class I just took over, I don't know much about the students in all aspects, but I think their enthusiasm for learning mathematics is still very high. Therefore, in this semester's teaching, we should pay more attention to the cultivation of students' learning interest and learning methods, so that different students can get different development.
Teaching measures
1, we should grasp the teaching objectives as a whole. Not only by experience, but how to mention it in the past and how to mention it now; Can't transfer textbooks. All the contents in the textbook should obey the unified teaching requirements, but should be adjusted appropriately according to the syllabus and teaching situation. It is necessary to prevent increasing students' learning burden.
2. Respect students and pay attention to the infiltration of learning methods. In learning, teachers should leave more time for students to explore, communicate and practice in class.
3. Pay attention to cultivating students' mathematical generalization ability and logical thinking ability. Pay attention to students' thinking process of acquiring knowledge.
4. We should pay attention to cultivating students' computing ability and ability to solve practical problems, and also encourage students to use what they have learned to solve simple practical problems in their daily life and study. Stimulate students' interest and cultivate the consciousness of applying what they have learned.
5. Pay attention to the proper infiltration of some mathematical ideas and methods, which is conducive to students' understanding of some mathematical contents.
6. Pay attention to the openness of teaching and cultivate students' innovative consciousness and practical ability. The arrangement of some examples and exercises in the textbook highlights the thinking process. In teaching, teachers should guide students to expose their thinking process and encourage them to think from multiple angles.
7. Carefully design lesson plans and pay attention to the application of multimedia, so that students can learn happily, easily and solidly.
8. It is necessary to infiltrate moral education and pay attention to cultivating students' good study habits and the spirit of independent thinking and overcoming difficulties.
Tisso
The teaching contents of teaching material analysis's textbook are as follows: 1. A preliminary understanding of multiplication; Second, table multiplication (1); Third, the preliminary understanding of the angle; Fourth, table multiplication (2); Fifth, the preliminary understanding of division; 6. Direction and position; Seven, the table teacher; Eight, the general review. The emphasis is on table multiplication and division, which is the basis of learning one-digit multiplication and division and multi-digit multiplication and division.
1, select vivid and interesting materials closely related to students' lives.
According to children's age characteristics and life experience, this textbook selects familiar, novel, interesting and close to students as materials, aiming at guiding students to know themselves, their families, their schools, society and nature in a planned way. Enable students to observe and associate the close relationship between mathematics and life, and make mathematics learning have practical significance.
2. Close the relationship between the subject materials to form a "situation string" and put forward a series of questions to form a "question string".
According to the teaching content and teaching objectives of the unit, several theme situations are designed. Thematic situation is a "information package" containing multiple information, and its presentation form is to divide the practical activities that students are interested in into several plots and arrange them into "story strings", thus leading to relatively independent questions; It can also be a complete reflection of all aspects of a real activity, which leads to a series of logically related problems-"problem string".
3. Construct an open "plate" arrangement with a certain thinking span, leaving as much thinking space as possible for teaching and learning.
4. Pay attention to cultivating students' problem consciousness, initial application consciousness and problem-solving ability.
5. Advocate diversified learning methods and attach importance to students' personality development.
The "cooperative exploration" part of each part is divided into two levels. The first level is to guide students to carry out cooperation and exchange activities on the basis of independent exploration, show their potential, and embody diversified methods and personalized learning. At the second level, using the knowledge and methods learned initially, through exploration activities such as association and reasoning, I independently solve the problems I am interested in in the comprehensive situation map, incorporate new knowledge into my cognitive structure, and initially master new knowledge. At the same time, learn problem-solving strategies and experience the fun of exploration.
6. Pay attention to the diversification of evaluation methods.
Analysis of learning situation
There are 27 students in Class 2, Grade 2, Senior High School, among whom 30% are excellent students, 50% are average students and 20% are poor students. These students are lively and active, respect teachers, love labor and consciously abide by classroom discipline. Most students can bear hardships and stand hard work, study hard, have a correct attitude towards learning and have a certain enthusiasm for learning mathematics. They have a solid grasp of what they have learned before. However, some students have not developed good study habits, poor classroom discipline, casual speech and poor academic performance.
This semester, we should teach students in accordance with their aptitude, give full play to the advantages of top students, and we can achieve success at a higher level. At the same time, do a good job in counseling and transforming students with difficulties, so that they can become top students as soon as possible and improve the teaching quality on a large scale.
