With the continuous development of social science and technology, Internet technology, communication technology and multimedia technology are widely used in classroom teaching, which changes students' learning and thinking mode and brings great opportunities and challenges to biology teaching in senior high schools.
Network teaching can provide students with a broad learning environment and rich biological resources, but teachers should recognize the advantages and disadvantages of network teaching and traditional teaching, integrate their teaching advantages, and promote the reform and development of biology teaching in senior high schools.
The rich teaching resources and forms of online teaching not only provide a communication medium for teachers and students, but also integrate the teaching content, which can deepen students' learning impression.
The advantages of online teaching are embodied in many aspects. First, online teaching can give full play to students' main role, teachers can organize and guide students' learning, create a good classroom environment for students, and make students improve their interest in biology and innovative consciousness in dialogue and cooperation. Secondly, online teaching can break the restrictions of textbooks on students, expand students' biological horizons and show hierarchical teaching knowledge. Moreover, network teaching is not limited by time and space, which is conducive to the cultivation of students' autonomous learning ability.
The shortcoming of online teaching lies in students' learning ability. Because some students' biological foundation, self-control ability and learning methods are not strong, there will be problems of not knowing what to learn and how to learn without the guidance of teachers, and the quality of students' biological learning can not be guaranteed.
Traditional teaching has spread for thousands of years and has its own unique advantages in biology teaching in senior high schools. In traditional teaching, teachers can tutor multiple students by one person, which reduces the cost of biology teaching and ensures the efficiency of biology teaching in senior high schools. Moreover, the traditional teaching method is convenient for teachers to manage students, improve the controllability and order of biology teaching, create a good teaching atmosphere, and stimulate students' awareness of biology learning in the teaching of teachers, students and students.
The disadvantages of traditional teaching are reflected in the backward teaching concept. Due to the influence of teaching conditions and teachers, it is impossible to guarantee the fairness of biology teaching in senior high schools. The traditional teaching classroom emphasizes the dominant position of teachers, and students can only listen passively, which is not conducive to the cultivation of students' innovative thinking and practical ability. Moreover, traditional teachers use unified teaching objectives and ignore students' individualized learning needs.
To sum up, the advantages and disadvantages of online teaching and traditional teaching are different. Teachers should look at these two teaching methods from the perspective of sustainable development, and integrate them perfectly into biology teaching in senior high schools to complement each other and form a comprehensive teaching effect.
In the process of integration, teachers need to make a scientific teaching plan, use online teaching to explain biological experiments, encourage students to operate, stimulate students' emotions in interactive communication, and build a diversified high school biology learning environment for students.
