1. Hearing AIDS, mainly recording, CD, language lab, etc.
This kind of teaching aid can provide standard pronunciation and intonation for students to imitate and play an exemplary role in English learning.
2. Visual teaching AIDS, mainly physical objects, models, wall charts, pictures, stick figures, projectors, etc.
Visual teaching AIDS can reproduce objective things intuitively, vividly and realistically, so that students can establish a direct connection between teaching content and objective things.
3. Audio-visual AIDS, mainly including TV, video, VCD, DVD, etc.
This kind of teaching aid can create a real language teaching situation and make students feel immersive. The effective use of this teaching aid can improve students' interest in learning and improve teaching efficiency.
4. Interactive teaching AIDS, mainly multimedia computers, computer networks, digital televisions, etc.
This kind of teaching aid can control the learning content according to the students' learning level. The effective use of this teaching aid can make students actively participate in behavior and emotion.
Reasonable and correct use of teaching AIDS can play the following roles:
(A) to attract students' attention and stimulate interest in learning. In teaching, we must find ways to attract students. As the saying goes, "it's not sweet to twist a melon", and it's the same for teaching. As a teacher, it is impossible to force knowledge on students, so we can only do it ourselves. As long as they are attracted, interested and eager to learn, the rest will be much easier. Teaching AIDS have such an effect.
(2) Cultivate students' observation and inspire students' thinking. People often praise a person as "really smart". This "smart" means "hearing and seeing", which means that intelligence includes the level of observation based on perception. Reasonable selection and use of teaching AIDS in our teaching can effectively guide students to train their observation ability, mobilize their inspiring thinking, help them save trouble and understand better, and become really smart.
(C) to promote students' perception of image and understanding of knowledge. The knowledge to be taught to students is the essence of human long-term accumulation and the result of high generalization and abstraction. If we only rely on the language that is also in the form of abstract symbols to teach, it is basically abstract to abstract, which will confuse students. If the teaching AIDS are used properly, the abstraction can be transformed into intuition, which is convenient for students to perceive and form concepts, so as to better understand abstract knowledge.
(4) Optimize the classroom teaching structure and improve the teaching efficiency. Every class has the same taste from beginning to end, and the teaching activities are just the same, and there is no change. Even good students sometimes sit still. Therefore, properly interspersed with teaching AIDS, your teaching activities will become colorful, not just your one-man show, then the classroom teaching structure will become rich, and students will no longer feel boring. At the same time, the ways and channels for students to receive information stimulation have also increased correspondingly, and their emotions have been adjusted, which will also help you improve the efficiency of classroom teaching invisibly.
