With the advancement of the new curriculum reform, the teaching concept under the new curriculum reform has been deeply rooted in the hearts of the people. In today's teaching, most teachers can change the new curriculum orientation and actively apply new teaching concepts and teaching methods to classroom teaching activities. In actual teaching, teachers should require all students to master basic knowledge and skills, and only top students can master the content of deepening and expanding, and they must never forcibly divide each knowledge point into three goals.

Geography is a basic course in senior high school. In high school teaching, teachers can teach students in accordance with their aptitude through hierarchical teaching. In high school geography class, teachers should set the goal of hierarchical teaching; Do a good job in hierarchical classroom teaching and arrange hierarchical homework. As long as teachers implement the layered teaching method well, it will certainly improve the efficiency of classroom teaching.

With the advancement of the new curriculum reform, the teaching concept under the new curriculum reform has been deeply rooted in the hearts of the people. In today's teaching, most teachers can change the new curriculum orientation and actively apply new teaching concepts and teaching methods to classroom teaching activities. Under the new curriculum reform, students have become the main body of classroom teaching, and teachers no longer only pay attention to individual students in the teaching process. As teachers under the new curriculum reform, in order to implement the requirements of the new curriculum standards and promote the process of the new curriculum reform, we must choose effective teaching methods in classroom teaching. Under the new curriculum reform, hierarchical teaching has been paid attention by teachers. Using hierarchical teaching method in classroom teaching can teach students in accordance with their aptitude on the basis of respecting their individual differences, so that every student can really gain knowledge through classroom learning, thus effectively stimulating students' interest in learning and improving classroom teaching efficiency.

Geography is a basic course in senior high school. However, due to the wide range of high school geography knowledge, many knowledge students have never experienced it. With their own life experience, students will encounter more or less difficulties in geography learning. Therefore, in senior high school geography teaching, teachers can find that students' geographical level is different and there are great differences. In order to make every student participate in classroom teaching activities and promote students' all-round development, it is necessary to adopt hierarchical teaching methods. The author has been engaged in geography teaching in senior high school for many years, and achieved certain results through the implementation of hierarchical teaching method. Next, the author talks about the implementation of hierarchical teaching method in geography teaching in senior high school combined with teaching practice.

First, the development of hierarchical teaching objectives

Because there are individual differences among students, it is inevitable that some students will not be taken care of if the same teaching objectives are adopted. In order to better teach students in accordance with their aptitude, teachers need to set different teaching objectives for students and carry them out according to their actual conditions? Tailored? The more the teaching objectives set by teachers are in line with students' recent development fields, the more they can stimulate students' interest in learning, enable students to acquire more knowledge and help them achieve their teaching objectives. Under normal circumstances, teachers will divide students into three layers according to their situation. A-level students with excellent academic performance can master the knowledge and skills they have learned and explore the knowledge in depth; Grade b is a student with average academic performance, who can master the knowledge and skills he has learned skillfully; Grade C refers to students with poor academic performance. Their basic knowledge is not solid and they lack the initiative to learn. Teachers should set different three-dimensional teaching objectives for students according to their actual situation. After determining the teaching objectives, teachers should carry out teaching activities and conduct teaching evaluation around the set objectives.

In actual teaching, teachers should require all students to master basic knowledge and skills, and only top students can master the content of deepening and expanding, and they must never forcibly divide each knowledge point into three goals. For example, the causes of geological disasters, the analysis of industrial and agricultural location factors, and the memory of the meaning of a geographical thing. There are no goals, but everyone is required to master them. The case analysis of these contents needs to be layered, requiring excellent students to make detailed and appropriate analysis, students with learning difficulties can make a general analysis according to the textbook, and intermediate students require detailed analysis. Aiming at the difficult knowledge such as earth movement, atmospheric movement and isoline interpretation, the target is refined. To do this, teachers not only need to carefully analyze textbooks, curriculum standards and examination outlines, but also need to truly realize that different people have different perceptions of everything.

Second, hierarchical classroom teaching

Classroom teaching is an important way for students to acquire knowledge. In classroom teaching, teachers must teach at different levels. In teaching, teachers should choose suitable teaching methods for students and stimulate students' classroom participation. No matter which teaching method is used, the teacher should take care of all the students. Problem-based situational teaching method is an important method in classroom teaching. Below, the author takes the problem-based situational teaching method as an example to discuss the hierarchical teaching in class. When applying problem-based situational teaching method in classroom teaching, designing effective questions is the key to classroom teaching. Teachers should carefully design appropriate questions for students at each level according to their level. The design difficulty of the problem should be moderate, not too difficult and not too simple. The question is too simple to stimulate students' desire to explore; If the problem is too difficult, students can't acquire knowledge through inquiry, which will also weaken their interest in learning. In order to design reasonable teaching problems, teachers need to make more efforts. When asking questions in class, teachers should leave simple questions to students with learning difficulties, and questions that need to be analyzed to draw correct conclusions to students with excellent academic performance. Only by letting every student participate in classroom teaching can we get the happiness of success. By designing teaching questions for students, it is not only beneficial to cultivate students' autonomous learning ability, but also to improve students' thinking ability and ignite the spark of students' wisdom.

Third, the arrangement of layered operation

Homework is a test of students' learning situation, and it is very important to assign homework. Teachers can only test students' learning effect and help them consolidate their knowledge by giving them homework. When assigning homework to students, teachers should also consider students' situation and assign students different homework. In homework, teachers can divide homework into compulsory homework and elective homework, all students must complete the compulsory homework, and the elective homework requires A-level students to complete, and B-level and C-level students can make appropriate choices according to their own learning situation. Students at the first level can also ask students at a higher level. With the help of students at a higher level, they can finish more homework. Through the arrangement of layered homework, students at all levels can understand their own learning situation, which is conducive to the realization of teaching objectives. Hierarchical teaching is an effective teaching method. Implementing hierarchical teaching in classroom teaching can give full play to students' main role, make students at all levels have learning enthusiasm, improve their learning initiative, let them better participate in classroom teaching activities and improve classroom teaching efficiency.
