How to improve junior high school students' interest in biology?

Interest is the greatest motivation for learning and seeking knowledge. A strong interest in learning can enhance students' autonomy in learning, cultivate research spirit, develop creativity and attach importance to the cultivation of students' interest in learning, which is one of the important ways to mobilize students' enthusiasm for learning, develop students' non-intellectual factors and improve teaching quality. Today, in the 2 1 century, life science and biotechnology have developed into a multidisciplinary and comprehensive high-tech field, and become one of the three pillars of high-tech development in the 2 1 century, which has received more and more attention and development in China. However, because it is not a senior high school entrance examination subject, our students and parents generally do not pay much attention to this subject, and it is easy to regard it as a "minor course" or "bean sprout course". If this situation continues, it will inevitably affect the development of biology teaching and life science and technology economy in middle schools in China in the future. There are many factors involved in changing this state. But for junior high school teachers, it is very important to play the leading role of teachers and mobilize students' interest in learning biology. How to improve students' interest in learning?

First, cultivate students' awareness of attaching importance to life science and improve their interest in learning biology.

Behavior is determined by consciousness. To stimulate students' interest in learning biology, we must first cultivate students' awareness of attaching importance to life science.

1, teachers should confidently publicize the importance of life science. Seize every opportunity and use various occasions and means to expound the importance of life science from all aspects of its influence and significance on human society. The author uses the first few minutes of class to introduce some latest developments in life sciences, and uses students' curiosity about biological sciences to improve their interest in learning.

2. Use circuitous propaganda strategy to arouse students' attention to life science. If the biology teacher only talks about the importance of biology, students may not believe it all, because they all have a point: every teacher says his subject is the most important. However, if there is a third party to talk about the importance of biology, such as the class teacher, it will be more convincing to use radio and television (CCTV's science and technology fair, science world and other columns), newspapers and magazines. If a lie is repeated a hundred times, it will become the truth, then the truth will become the absolute truth if repeated a hundred times.

3. Combine the vital interests of students. Students' personal experiences in daily life, industrial and agricultural production, medicine and health, environmental protection, etc. It can be used to make students understand the importance of learning biology well. Try to combine the local actual situation in class: use local examples, names and some inappropriate local living and eating habits.

Second, create a good learning environment and stimulate interest in learning biology.

Middle school students are in a period of long body and long knowledge. They have a strong thirst for knowledge, but their attention is not easy to concentrate, and they are easily influenced by external environmental factors, resulting in the phenomenon of partiality and even weariness of learning, especially biology, which is more easily ignored by students. Therefore, how to create a good learning environment for students is very necessary to cultivate students' interest in learning biological knowledge and stimulate their curiosity about biological knowledge.

1, learn the first lesson well and stimulate students' interest in learning. A good beginning is half the battle. The success or failure of the first class teaching will play a decisive role in the follow-up teaching. Therefore, the teaching of the first class must strive to leave an unforgettable impression on students. For example, when I was "exploring the mysteries of biology" in the first day of junior high school, I listed some biological phenomena that students were generally exposed to according to the characteristics of content structure in the teaching process. At the same time, according to the epidemic situation of SARS and bird flu in the local area, I asked, "Why are SARS and bird flu easy to spread in spring and winter? Why did everyone go to crowded places and eat less poultry food during this time? " . In recent years, the local SARS and avian influenza epidemic has caused casualties and many social rumors. Therefore, questions can not only attract students' attention, but also stimulate students to explore questions, thus stimulating students' desire to learn biological knowledge.

2. Wonderful new lesson introduction can make students excited. The introduction of classroom teaching, like the "introduction" of opera and the "prologue" of film and television drama, has the task of brewing emotions, concentrating students' attention, infiltrating themes and bringing situations. Well-designed lead-in can grasp students' heartstrings, arouse students' doubts and interests, promote students' high spirits and enter an exciting state of curiosity. There are many ways to import, such as asking questions, discussing, setting questions, choosing stories, etc. , which can be used flexibly according to the characteristics of the content. For example, when introducing the structural hierarchy of animals, we can ask the following questions: (1) Why can people recognize warmth, distinguish things and complete various actions? (2) Adults generally weigh more than 100 kg, but how can they be composed of a cell that can only be observed under a microscope? Whether it is nested like building a house in the countryside. In this way, students can distract their thinking and think about problems with interest: cells >；; Tissue > organ > system > human body. On the contrary, it can't inspire students' thinking, nor can it inspire students to think positively. Students don't know how to learn. What should I study? Therefore, it is essential to doubt the introduction of the new curriculum. But we should pay attention to the way of asking questions, with vivid examples, interesting questions and thoughtful thoughts.

3. In the whole process of biology teaching, teachers must be full of passion and love. People are emotional animals, and being emotional and energetic is an important magic weapon for teachers to mobilize students. Teachers must be full of passion and enthusiasm in the whole teaching process, so that students can feel their love for biological science, education and life, let students feel their optimistic, positive and enterprising attitude towards life, and have a strong appeal and shock to students. Love is the source of power to promote the educational process. Teachers should be full of love for each of their students, care for them from the aspects of ideology, study, life and physical and mental health, help them, always think of them, let them get the love of their teachers, and they will love their teachers. As the saying goes, "love me, love my dog", students naturally like students' things.

Third, attach importance to experimental teaching, carry out extracurricular scientific and technological activities, and stimulate interest in learning biology.

There is a sign on the wall of the Washington Children's Museum: "If you hear it, you will forget it; if you see it, you will remember it; if you do it, you will understand it." In teaching, I found that students like experiments, especially those who can do experiments by themselves. Meeting the urgent needs of students is also an effective way to stimulate students' interest. Therefore, it is necessary to do a good job in each experimental class, especially in the first experimental class, and ask students to divide their work reasonably on the basis of observing discipline. Teachers should not only do experiments, but also be proficient in them. Before the experiment, they should explain the purpose and steps of the experiment to arouse students' interest. In the process of experiment, we should care and encourage students, find students with difficulties, give patient guidance, and correct mistakes and omissions in the experiment in time. But we can't arrange students to do experiments instead of students, and we can't criticize students casually, so as not to affect their enthusiasm for doing experiments. After the experiment, each student is required to write an experimental report, stating the observation results, and then the teacher marks it. This not only improves students' interest, but also improves their operational ability. The second classroom provides a place for students to continue to study and study biological knowledge after class, and also provides a lot of experimental materials for experimental teaching. Extracurricular interest activities are not only a concrete form of second classroom teaching, but also an important way to improve and develop students' interest in learning. In teaching, students who have a strong interest in biology can organize biological interest groups, and take them as the backbone to carry out a wide range of extracurricular activities, such as biological story meetings, biological lectures, biological competitions, biological extracurricular experiments, biological field practice, scientific research projects and so on. The development of extracurricular activities is not only conducive to mobilizing students' enthusiasm, changing passive learning into active learning, improving and developing students' interest, but also conducive to broadening students' horizons, cultivating students' ability and improving students' quality in an all-round way.

Fourth, strengthen the guidance of teaching method exploration and learning methods, and maintain the interest in learning biology.

Experienced teachers know that it is not too difficult to stimulate students' interest, but it is very difficult to maintain this interest in learning for a long time, especially if the grades have not improved after a period of serious study. On the contrary, if teachers teach well and students learn well, then students will learn relatively easily, and the learning effect will be good, and students will be satisfied and happy from learning. Because the sense of success can be continuously strengthened, the enthusiasm and enthusiasm for learning can be maintained for a long time. Therefore, it is very important for teachers to explore teaching methods and strengthen the guidance of students' learning methods in the teaching process to mobilize students to learn biology well. On the one hand, in teaching, we should make use of rich language arts and vivid and emotional examples, highlight key points and difficulties, pay attention to two-way communication with students, give full play to students' main role, adopt various visual teaching AIDS and multimedia technologies and other modern educational technologies for heuristic teaching, combine teaching with practice, strive to solve problems in class, pay attention to quality in 45 minutes, and reduce students' learning burden after class; On the other hand, do a good job in guiding students' learning methods, including how to make a study plan and how to master all aspects of learning skills (reading skills, memory methods, methods of summing up knowledge, skills of asking questions from teachers, etc.). ) and how to plan the time. When students master the learning methods, they will be active, relaxed and targeted, the learning effect will naturally be greatly improved, and their enthusiasm will be mobilized to the maximum extent.

Through practice, I deeply realize that in the contradiction between teaching and learning, we should not only give full play to the enthusiasm of teachers, but also pay attention to mobilizing the enthusiasm of students. Only by organically combining the two passions can the ideal teaching effect be achieved. Let's remember Spencer's educational advice: keep children interested.
