Curriculum reform is a change in learning methods and teaching methods. It changes the tendency that the curriculum pays too much attention to knowledge transmission and emphasizes the formation of positive learning attitude, making the process of acquiring knowledge and skills a process of learning to learn and forming correct values. [1] The curriculum reform in senior high school is different from that in primary and secondary schools, which is mainly reflected in: the curriculum reform in senior high school implements the credit system, and the curriculum is divided into compulsory courses and elective courses, so that students can choose courses across classes, which is not mentioned in the curriculum reform in primary and secondary schools. In addition, the school also puts strengthening moral education at the top of all educational work, which shows that the state attaches importance to students' ideological and moral education. [2] The curriculum reform in senior high school is based on the curriculum reform in primary and secondary schools. While absorbing the advantages of curriculum reform in primary and secondary schools, due to lack of experience, some problems will inevitably appear in the promotion process.

First, high school curriculum reform is inevitable

1. Teachers' understanding of the new curriculum concept

Because teachers have adapted to the traditional teaching concept of "teacher-oriented and student-centered", it is difficult for most teachers to have a systematic and profound understanding of the new curriculum reform, teaching reform and examination reform in a short time, which may lead to teachers' inadaptability to teaching and thus affect the teaching effect. The new curriculum reform puts forward higher requirements for teachers' knowledge literacy, organizational ability and ideological morality, but whether teachers can really do this in the actual curriculum reform remains to be considered.

2. The new curriculum reform gives students the feeling of "seeing flowers in the fog and the moon in the water"

By investigating senior high school students' feelings about the new curriculum reform, we know that students generally think that the textbooks in senior high school have a wide range of knowledge, and the new textbooks involve a lot of knowledge, but there is no deeper explanation, which makes students' understanding of knowledge only superficial, and it is often difficult to form a complete context of knowledge after learning, and the teaching progress is too fast, and students often have not fully understood it, but the next class has already begun. Students also report that there are too few exercises after class, and there are no exercise books matched with textbooks, which not only brings many difficulties to teachers' teaching, but also affects students' learning and development.

3. Teachers' ability to apply modern technology is questionable.

The new curriculum reform requires teachers to have the ability to apply modern technology and skillfully use multimedia technology. However, in actual teaching, some older teachers have some shortcomings in the application of modern technology, which can not adapt to multimedia teaching well, resulting in boring classroom teaching content, lifeless classroom, low students' learning enthusiasm and unsatisfactory learning effect. This will undoubtedly bring a series of problems to the teaching of new curriculum reform.

Second, the causes of problems in the new curriculum reform in senior high schools

1. Analyze from the macro level.

First of all, the ultimate goal of the reform is to let more students receive better education and really promote students' learning and development. However, in the specific practice of implementing the curriculum reform, there are problems in the implementation process because the state only makes rough principles and regulations on the curriculum reform plan and lacks specific operational implementation rules. Secondly, due to the traditional teaching concept, it is difficult for principals, teachers and parents to have a new understanding of curriculum reform. In the process of implementation, it is difficult to change the teacher-centered teaching method in the classroom. Students are still completely passive, and the classroom is still a stage for teachers alone. Therefore, under the influence of traditional ideas, there are problems in the implementation of curriculum reform. Finally, in the new curriculum reform, the investment of school funds, the expansion of teaching facilities and equipment, the promotion of related reforms and the introduction of supporting policies can not keep up with the pace of the new curriculum reform in senior high schools. As the saying goes, haste makes waste. The high school curriculum reform, which pursues speed but ignores quality, has affected the development of the new curriculum reform.

2. Analyze from the micro level.

First of all, in the new curriculum plan, it is required to change from emphasizing teachers' "teaching" to emphasizing students' "learning". The new curriculum advocates teaching for students' learning, but in traditional teaching, teachers say that teachers lead students and students revolve around teachers. In the long run, students get used to passive learning, and the subjectivity of learning gradually disappears. As a result, students can't quickly adapt to the fact that they are the protagonists in the new curriculum reform, which further makes students lack enthusiasm and initiative in the classroom and affects the further development of the new curriculum reform. Secondly, the relationship between parents and teachers seems to have been controlled and dominated for a long time. No matter how important parents are, it seems that no one is not afraid of teachers, which leads to the apparent harmony and actual conflict between parents and teachers. [3] Therefore, in the new curriculum reform, teachers and parents lack communication, and it is difficult to sit on the educational problems arising from the business curriculum reform. Therefore, teachers and parents are not good at cooperation in curriculum reform, which is also an important reason for the problems in curriculum reform. Finally, there is differentiation and opposition between the research of educational researchers and teachers' educational practice. People who specialize in curriculum reform recommend their ideas to teachers and force teachers to act according to their own intentions, so that many theories are just written on paper and many suggestions cannot be implemented. For this reason, some experts began to accuse teachers of not doing their own teaching work well, which led to the disagreement between teachers and experts on curriculum reform, which caused the disconnection between educational theory and educational practice and affected the progress of curriculum reform.

Third, the problem-solving strategies in the new curriculum reform of senior high school.

1. In the new curriculum reform, teachers and students should cooperate and learn through cooperation.

In the new curriculum reform, teachers should become students' learning partners, guides and participants. Because the teaching process is an interactive process of communication and development between teachers and students, it means that teachers and students should have equal dialogue, and teachers should change from condescending authority to "equal chief". Teachers should not only pay attention to students' learning, but also understand students' lives in order to truly become students' mentors and friends.

2. In the new curriculum reform, teachers should change the traditional teaching concept.

In the new curriculum reform, teachers should change into the curriculum teaching concept of serving students for further study. Because students' mission is not only to get into a good university, but also to learn to be a man, teachers must establish the curriculum teaching concept of paying equal attention to knowledge education and quality education, so that students can develop morally, intellectually and physically in an all-round way.

3. Teachers should have modern educational technology in the new curriculum reform.

In the new curriculum reform, teachers must master modern information technology and make it serve education and teaching. Teachers who master modern information technology will show the teaching content to students more intuitively and clearly, so that students can see the new course content at a glance and increase their enthusiasm for learning. Therefore, we should give full play to the advantages of information technology and provide students with rich and colorful course contents and convenient learning methods.
