Interest is the best teacher. Only by fully arousing students' interest can the classroom come alive. At this time, the knowledge base is just a stepping stone, which can better improve the quality of biology teaching. The following is a model essay on the existing problems and improvements in biology teaching in senior high school on 20 17, which I shared with you by J.L.

Abstract: Under the background of new curriculum reform in China, biology teaching in senior high schools is facing higher challenges. The implementation of the new curriculum standards is undoubtedly a powerful medicine for junior high school biology teaching. The implementation of this teaching process requires high school teaching methods to be more scientific and theoretical, thus making the teaching process more targeted and effectively improving classroom teaching efficiency. This paper mainly aims at the requirements of this new curriculum reform, makes further analysis and discussion on biology teaching in senior high schools, and puts forward some optimization countermeasures for your reference.

Keywords: new curriculum reform; Biology teaching in senior high school

Although the high school biology teaching has made some progress and innovation with the implementation of the new curriculum concept, there are still some problems in the high school teaching process. How to adjust and improve this kind of problems is one of the important goals of the current teaching task, and the reform is to analyze and understand the existing problems, find the nodes of the problems in the discussion of the problems, and then put forward efficient solutions through a series of practical processes. According to this basic principle, the author makes a preliminary discussion on how to carry out biology teaching in senior high school under the new curriculum reform, and puts forward some preliminary optimization countermeasures.

First, the new curriculum reform in high school biology teaching problems

1. Teachers' own quality is not high. Whether the teaching content can be vividly presented to students depends on the teacher's careful design of the classroom content. Therefore, if a teacher's personal ability is not strong and he doesn't have a full sense of responsibility, it is easy to do things in a perfunctory way in the teaching process, which seriously affects the improvement of biology teaching level in senior high schools. If senior high school biology teachers do not fully understand the new curriculum reform and further explore its significance, they will not be able to better implement this concept in teaching tasks. However, the times are progressing, and the continuous development and progress of biotechnology also puts forward some higher requirements for the comprehensive professional knowledge level of biology teachers in senior high schools. If teachers are too formalistic in teaching activities, the teaching of knowledge will ignore students' individual research and reflection on learning, thus affecting the implementation and implementation of biology teaching ideas.

2. The classroom teaching method is single. Biology teaching faces nature. For various biological species, understanding and understanding them is one of the important means to cultivate outstanding talents in biology. Nature is so ingenious that students can only get in touch with it in order to understand it more deeply. Biological knowledge without a certain practical foundation is bound to be empty in the teaching process, so biological experiment is an important part of biology teaching in senior high school. However, due to the lack of experimental facilities and projects in some schools, the experimental content can not be fully developed, thus simply making the textbook content a single paradigm for teachers' teaching. Let students' thoughts become paralyzed, so that students do not develop good study habits.

Optimization countermeasures of biology teaching in senior high school under the new curriculum reform

1. Pay attention to cultivating high school students' modern consciousness. It is an effective and important way to cultivate students' modern consciousness through some teaching paradigms and teaching activities. Therefore, in the teaching process, teachers pay attention to cultivating students' modern consciousness on the basis of imparting senior high school biology knowledge, which can improve students' comprehensive biological quality and promote all-round progress. For example, in order to enable students to establish a correct ability to explore biological sciences, it is necessary to strengthen their profound understanding of biological sciences. Multimedia can be used in the classroom, so that students can watch some biological science movies and videos, such as The Origin of Life and the Reform of Modern Biotechnology, so that students can have a sense of modern biological science and arouse their sense of the times, thus cultivating high-tech talents who can adapt to the development of modern biological science.

2. Improve teachers' personal professional quality. The improvement of teachers' own ability is a leap in the quality of biology classroom teaching in senior high school. Personal ability is not only the premise of understanding the teaching content well, but also the challenge to the professional knowledge structure of biology teachers in senior high schools. In order to meet the all-round development needs of each student, we must adapt to the students' scientific theoretical knowledge and practical analysis ability, and constantly improve the quality and level of biology teaching in senior high schools. Teachers can adjust their teaching paradigm in time according to their usual practice classes, and further carry out hierarchical education for each student. In order to deepen the educational reform, we must do a good job in biology teaching concepts required in teaching tasks to meet the needs of the new curriculum. For example, when organizing students to carry out biological experiments, teachers only play a guiding role, mainly to inspire students' self-help ability and independent thinking ability, participate in the operation by themselves, then analyze and discuss in the group, and finally draw scientific conclusions. Such a process of exploring questions and seeking truth is a bridge for students to improve their self-ability and construct their thinking paradigm, laying a solid foundation for better adapting to the implementation of the new biology curriculum reform.

3. Optimize online teaching resources. It is a more constructive teaching paradigm to make full use of network resources in the teaching process of biology courses in senior high schools. Biology, as an experimental subject, how to integrate the relationship between classroom teaching and experimental teaching and optimize classroom curriculum resources is a very critical process. When integrating resources, teachers should change the traditional teaching concept, optimize the network teaching concept, set up teaching objectives, dare to use new technical tools, and go out of the classroom and laboratory for classroom teaching.

4. Stimulate students' interest and improve the classroom atmosphere. Interest is the best teacher. Only by fully arousing students' interest can the classroom come alive. At this time, the knowledge base is just a stepping stone, which can better improve the quality of biology teaching. Biology teaching in senior high school should take students as the main body and aim at stimulating students' enthusiasm for learning and their learning concept of accepting knowledge. Create a classroom atmosphere that is not boring and inspire each student's thinking. For example, we can reduce the pressure on students by reducing homework assessment and adding some interesting teaching activities in the classroom. The solitaire game of biological chain and the simulated competition of intracellular substances can enable students to study consciously and actively in a pleasant classroom atmosphere, and will not produce depression. Under the requirements of the implementation of the new curriculum reform, senior high school biology is a complex comprehensive experimental course. We should try our best to cultivate high school students' modern consciousness so that their thoughts are no longer bound. At the same time, it is necessary to improve teachers' professional ability, carry out some inquiry teaching, and properly integrate some network resources in the teaching process, fully stimulate students' interest, enliven the classroom atmosphere, and actively explore better countermeasures for biology teaching in senior high schools under the new curriculum reform. All this requires unremitting efforts and persistence. Of course, each teacher's teaching content and mode are different, and he has his own unique understanding of some teaching methods. But on the whole, as long as we can improve the teaching methods with effective teaching ideas, the teaching quality will be greatly improved in the end.
