First, teaching AIDS can improve students' interest in learning.
It is very important to improve students' interest in geography class. Teaching AIDS can stimulate students' curiosity, concentrate students' attention, enhance students' interest in learning and thirst for knowledge, create a pleasant teaching situation, give full play to students' dominant position, and achieve the goal of teachers and students participating in teaching together. Good teaching AIDS, such as the "three-ball instrument", can make students have a panoramic understanding of the three-ball movement of the sun, the moon and the earth, and can clearly see the phenomena such as seasonal changes, alternation of day and night, solar eclipse and lunar eclipse caused by the three-ball movement. Attract students' attention to the teaching content and let them actively participate in learning, so as to tell the knowledge that should be taught incisively and vividly and achieve good teaching results. Conditional schools should also make more use of multimedia and play some pictures or videos related to the classroom content.
Second, teaching helps students form the habit of finding and solving problems.
It is often better to cultivate students' ability to find and solve problems through teaching AIDS than simply textbooks. Because it is easier for students to find substantive problems between entities and words, as the saying goes, "practice is the only criterion for testing truth." When explaining the double helix structure of DNA in biochemistry, the language description can't achieve the teaching purpose. Therefore, in class, we use a rope as a teaching demonstration of double helix structure to stimulate students' thinking, so as to cultivate students to find their own problems and think about how to solve them, form habits and then apply them to life.

Third, teaching can help students experience learning and improve their ability to apply what they have learned.
Teaching AIDS directly or indirectly come from life, which is closer to life than books and makes students feel more intimate. Such as domestic garbage, waste water, statues damaged by acid rain, animal and plant specimens, etc. These things around students' lives let students know that geography is something around them and closely related to life. On weekends or other free time, students can be organized to visit sewage or tap water treatment plants, science and technology museums, museums or other places in the wild to introduce physics teaching AIDS to students, so that students can record their own characteristics and phenomena and write their own feelings. At the same time, the relevant knowledge points are commented and explained in class, so that students can experience, learn and grow in the process of visiting, and teaching AIDS can promote students to apply what they have learned, improve their ability to apply what they have learned and broaden their horizons.

Fourth, intuitive teaching AIDS play a bridge role, and self-made teaching AIDS cultivate students' innovative ability.
Middle school students have a small range of activities, lack of social experience, limited spatial imagination and thinking ability, and many things and phenomena are difficult to understand. Visual teaching AIDS play a good role as a bridge and can effectively improve academic performance. Maxwell said: "The educational value of experiments is inversely proportional to the complexity of instruments. Although the musical instruments made by students often break down, they can learn more than those carefully tuned! " Self-made teaching AIDS are a kind of teaching and research achievement, which can not only supplement the shortage of teaching instruments and save money, but also change the traditional educational concept and backward teaching methods and cultivate the spirit of bold reform and innovation of teachers and students.
To sum up, teaching AIDS are as important as teaching materials in the teaching process. Teaching AIDS have always played a very important role in teaching, especially in the teaching process of geography, physics, chemistry, biology and other disciplines with experiments as the main body. Nowadays, innovative education is very important in the reform of the new curriculum standard education system, and teaching AIDS have played a decisive role. Therefore, increasing the use of teaching AIDS in the teaching process is completely in line with the requirements of the new curriculum reform and should be paid attention to and widely used.
