It takes real specimens, models and pictures as carriers, transmits teaching information and carries out specific teaching activities, emphasizing that classes should be full of pictures and books should be accompanied by illustrations. The presentation of visual AIDS should be placed at a reasonable distance in front of students, so that students can see the whole first, and then distinguish the various parts, so as to attract and keep students' attention as much as possible. The essence of intuitive teaching is an intuitive technology to impart observation experience, which attaches importance to the selection and application of intuitive teaching AIDS and teaching materials, but ignores the design, development, production, evaluation and management of teaching materials.
The types of intuitive teaching include: object intuition, model intuition and speech intuition.
(1) physical intuition
View is an intuitive way to directly perceive actual things. For example, observing various physical specimens, demonstrating various experiments, and visiting factories or rural areas are all intuitive. The advantage of physical intuition is that it gives people a sense of reality and intimacy, and the perceptual knowledge obtained is closely related to the actual things, so it is conducive to stimulating students' interest in learning and mobilizing their enthusiasm for learning, which can play a role in real life quickly. Its disadvantage is that the essential and non-essential attributes of physical intuition are related to everything, and because of the limitation of time and space and sensory characteristics, the characteristics and connections of many things are difficult to be directly perceived in physical intuition. Therefore, it is not the only way of intuition, there must be other kinds of intuition.
(2) The model is intuitive
Modeling is the simulated image of things. The so-called simulated intuition is an intuitive way to directly perceive the simulated image of things. For example, the observation and demonstration of various pictures, charts, models, slides, teaching films, televisions, etc. Its advantage is that it can eliminate some irrelevant factors artificially and highlight the essential elements; According to the observation needs, the visual range can be expanded by means of size change, dynamic and static combination, virtual and real exchange and color contrast. , not limited by physical intuition, improve the visual effect and expand the visual range. Therefore, it has become an important means of modern teaching and an important content of modern educational technology research. However, because the model image is only a simulated image of things, it has a certain distance from the actual things. Therefore, in order to make the knowledge gained through the model image play a better directional role in students' life practice, on the one hand, we should pay attention to comparing the model image with what students are familiar with, and at the same time, we should combine the model image intuition with the physical intuition as much as possible.
(3) Intuitive speech
Speech intuition is an intuitive form formed by students' perception of language material forms (pronunciation and glyphs) and understanding of semantics under the influence of visualized language. The advantage of intuitive speech is that it is not limited by time, place and equipment conditions, and can be widely used; At the same time, we can also use harmonious and vivid examples to stimulate students' feelings and stimulate their imagination. However, the representation produced by language intuition is often not as vivid, complete and stable as physical intuition and model intuition. So if possible, try to match the intuition of the object and the model.
