First, measures to improve the quality of junior high school biology teaching

First, to develop practical teaching objectives

Under the background of the new curriculum reform, teachers should deeply understand the spiritual essence of the new curriculum standards and formulate practical teaching objectives according to the requirements of the new curriculum standards. The new curriculum standard of junior high school biology is the basis for teachers to carry out biology teaching. In teaching, teachers should use it flexibly, so that it can really play its role and improve students' learning effect. The new curriculum standard focuses on changing teaching concepts, innovating teaching methods, guiding students to carry out autonomous learning, cooperative learning and inquiry learning, giving full play to students' main role and subjective initiative in learning, so that they can flexibly apply what they have learned to practice and truly apply what they have learned. Teachers should formulate practical teaching objectives, carefully design teaching contents and objectives, strive to teach students in accordance with their aptitude, and effectively improve students' knowledge, ability and emotional attitude.

Second, strengthen practical teaching and improve students' practical ability.

After the implementation of the new curriculum standards, teachers should completely change the indoctrination teaching method. In teaching, they should not only look at the exam results, but also pay attention to the learning process. They should try their best to stimulate students' divergent thinking and urge them to master biological knowledge in understanding. In teaching, teachers should leave enough time for students to think and ask questions, and stimulate students' interest in learning by creating teaching situations. In addition, teachers should attach importance to practical teaching, let students learn biological knowledge dynamically and intuitively through experimental teaching and practical activities, improve students' practical ability through practical operation, and let students have a deeper impression and memory of what they have learned through vivid case teaching.

Give full play to the advantages of multimedia teaching

The new curriculum reform advocates the use of modern teaching methods in teaching. Multimedia technology integrates pictures, animations, videos, words and sounds, which can vividly display biological knowledge in front of students and give them vision, hearing and senses in an all-round way, thus stimulating students' interest in learning, mobilizing their enthusiasm for learning and making them actively engage in learning. In teaching, teachers should give full play to the advantages of multimedia technology to improve the teaching effect. Multimedia technology can only play an auxiliary role in teaching. Teachers should not rely too much on and exaggerate the role of multimedia technology, so that multimedia plays a leading role in the classroom and affects students' thinking. When making multimedia courseware, teachers should carefully design, reasonably select pictures and videos according to the teaching content, and add appropriate text descriptions to make the teaching content more concrete and intuitive, so as to attract students' attention, facilitate students to have a deeper impression on what they have learned, deepen their understanding and memory, and further improve the teaching quality.

Fourth, to stimulate students' awareness of inquiry

The new curriculum reform not only requires teaching students more knowledge in teaching, but more importantly, it enables students to master scientific learning methods and make them love learning, be good at learning and enjoy learning. In the teaching process, while imparting knowledge, teachers should let students master certain learning skills, guide students to carry out cooperative learning, autonomous learning and inquiry learning, pay attention to students' growth and development, guide students to inquiry learning through various teaching means and methods, and improve students' ability to ask, analyze and solve problems. For the exam, which is an indispensable part of the learning process, teachers should teach students the necessary ability to take the exam, not to say that they should master more knowledge to get good grades, but to teach students to carefully examine the questions, grasp the key points of the questions, eliminate interference, and correctly answer the questions by finding hidden conditions. In addition, teachers should give correct guidance and encourage students to explore, so as to improve students' exploration consciousness and comprehensive ability.

Fifth, strengthen practice and improve learning ability.

Teaching activities need the participation of teachers and students. In this process, teachers should give full play to their guiding role, completely change the traditional indoctrination teaching method, attach importance to students' dominant position in learning, and let students actively participate in learning, thus improving teaching quality. The main purpose of junior high school biology teaching is to cultivate students' innovative thinking ability, careful observation ability and practical operation ability, which requires teachers to be good at guiding and inspiring, and make full use of classroom teaching time to impart biology knowledge and skills to students in order to improve their learning ability. To achieve the above goals, teachers should not only have rich knowledge and strong organizational expression ability, but also seriously understand the spirit of the new curriculum reform, fully understand students' cognitive rules, acceptance ability, learning foundation and learning interest, and reasonably choose teaching methods, teaching contents and teaching modes in combination with students' reality. In teaching, teachers should highlight the key and difficult problems in teaching, and strengthen students' understanding and memory of knowledge through intensive lectures and more practice. In addition, practice can effectively consolidate knowledge, so teachers should design teaching problems according to the teaching content, and guide students to improve their ability to analyze problems through practice, so as to master what they have learned and improve their autonomous learning ability.

Second, summary

In short, under the background of the new curriculum reform, teachers should constantly innovate teaching methods, change teaching concepts, fully understand the importance of junior high school biology teaching, set practical teaching objectives, improve students' practical operation ability through practical teaching and multimedia teaching, stimulate students' interest in learning and inquiry consciousness, so as to improve the quality of junior high school biology teaching and promote students' all-round development.

Second, junior high school biology teaching thinking abstract: The biggest factor for the success of biology teaching is that teachers fully understand students, correctly guide students according to their learning situation, and adopt flexible and effective teaching methods. Only in this way can we improve students' thinking ability, observation ability and inquiry ability, better display their knowledge and interest in biology, and lay a solid foundation for students to learn biology well.

First, the teaching process should highlight the teaching effect of teacher-student interaction and student-student interaction.

With the advancement of the new curriculum reform, more and more attention has been paid to effective classroom teaching. "Teacher-student interaction, student-student interaction" is the main factor to highlight the effect of classroom teaching, and its fundamental purpose is to correctly guide students' thinking and actively cultivate their thinking ability. In the teaching process, only by making students really move, can teachers understand students' development and their knowledge, and can proceed from students' reality and teach at different levels, thus stimulating students' interest in biology and improving their ability to analyze and solve problems. For example, when studying "cells are the basic unit of life activities", I asked students to observe tiny objects and cells through a microscope. Before observation, I let students know the structure of the microscope and learn the standard operation method. When students operate the microscope by themselves, they show great enthusiasm and interest, listen to the teacher patiently and carefully, and soon master the use of the microscope. The students are very careful in making the epidermal cells of onion scales and the pulp cells on the surface of cucumber, because they are eager to find out what kind of state these vegetables will be under the microscope. I also ask students to form groups and exchange observations, so as to form a good interaction between students. In this good classroom atmosphere, students learned about the different forms and basic structures of plant cells, and achieved the expected teaching effect.

Second, the teacher should be a regulator of students' emotions.

Emotion often directly affects students' attitude and efficiency in class. Studies have proved that when students are in high spirits, all kinds of senses can be mobilized, and they will accept information from the outside world and knowledge from teachers very quickly, and even play beyond their normal level. On the contrary, there will be a phenomenon of being out of state and not knowing what the teacher is talking about. Therefore, experienced teachers pay great attention to adjusting the classroom atmosphere and students' emotions. In this way, students will not be affected by bad emotions, so that their thinking can be completely concentrated in the classroom, thus improving the efficiency of listening to lectures. For example, once in a biology class, perhaps because of the afternoon, the students were depressed and a little sleepy. That class just learned the content of knee jump. I had a brainwave and let each student experience this "magic" knee jump personally. First, let the students sit in chairs. This requirement makes the students excited and full of doubts, and the students don't know the purpose of doing so. Then I mysteriously asked the students to bend their knees and let their calves droop freely. Next, I asked the students to tap the ligament below the knee with the inner edge of the palm. At this time, the students' calves reacted with a quick forward kick, and the students all laughed. In the face of students' excited and curious expressions, I took the opportunity to explain the principle of knee jerk reflex to students, which effectively improved the efficiency of students' lectures.

Third, adopt humorous and relaxed teaching methods.

Biology seems boring, but it is actually very interesting, because it studies plants, animals, bacteria and other organisms, including our own bodies. Biology is very important to human beings. Economic development, social progress and the improvement of human life quality are closely related to biology. So how should teachers guide students to learn biology well?

Bold use of new teaching methods

I think teachers should adopt humorous and relaxed teaching methods in class. In practical teaching, there is not a student who doesn't like humorous teachers. In a relaxed and humorous teaching atmosphere, students will have no pressure in their hearts, and their mood will be very comfortable, which will often get twice the result with half the effort. For example, I will play the role of a student when I meet something I have to master. Students ask questions and I'll answer them. When I recite the content fluently, the students will be full of admiration. Or I'll recite it with the students and see who recites it first. Sometimes I recite my mistakes on purpose, and my classmates will point out my "mistakes" very seriously. Students like this method very much, and they are more willing to be teachers' "marking guests". Over time, students are full of interest in biology, especially in biology classes.

Second, biology teaching should be closely linked with life.

Junior high school students are curious and always like to ask why. In view of this feature, in my biology class, I often contact with real life, such as leaves, flowers, roots and stems of plants in life, and some specimens such as butterflies and bees can be used as life props in class. These energetic props, to a great extent, have stimulated students' motivation and enthusiasm for learning biology, aroused students' awareness of loving life and biology, and better cultivated students' interest in learning biology. For another example, asexual reproduction of plants includes layering, cutting and grafting. When I was teaching this part, I brought the newly listed "Apple Pear" to the classroom, and explained the grafting principle to students with videos, which not only made students feel the wonder of nature, but also enhanced the teaching effect.

Fourth, summary.

In short, the biggest factor for the success of biology teaching is that teachers fully understand students, correctly guide students according to their learning situation, and adopt flexible and effective teaching methods. Only in this way can we improve students' thinking ability, observation ability and inquiry ability, better display their knowledge and interest in biology, and lay a solid foundation for students to learn biology well.
