These three kinds of experimental operation popular science education activities are mainly aimed at preschool children's experimental operation activities, which are divided into two stages according to children's age: 0-3 years old and 3-6 years old.
The first stage: 0-3 years old, it is very important to guide children to operate or help them to operate, which is very important for developing children's hand control ability, eye-hand coordination ability and intelligence, allowing children to establish some basic life feelings and let children develop healthily. For example, how to use spoons and chopsticks, how to operate pens to draw, open caps, build blocks, operate plastic knives to cut cakes, play with mud, water, sand and toys. , are children's operational activities during this period.
The second stage: 3-6-year-old experimental operation plays a vital role in children's knowledge and experience accumulation and intellectual development, which can greatly satisfy children's desire for exploration and cultivate children's interest in science. Piaget pointed out that the construction of children's knowledge and experience must be completed by children through their own operational activities. He also believes that children's intelligence originates from material activities, and children's intelligence is actively constructed through the interaction of individuals, environments and materials, and gradually establishes a more accurate intellectual structure.
The significance of experimental operation to children goes beyond this. The goal of children's science education activities points out that the real purpose of children's activities is to cultivate and improve children's scientific literacy. Therefore, as teachers, what we have to do is to guide children to experience and feel the inquiry process, experience the inquiry method, and let them enjoy the fun brought by science in this process, and cultivate children's love for science, which is more important and essential than acquiring scientific knowledge.
