If the child is doing the wrong question, the most spoken sentence of the parents and the teacher is probably "How is it so careless?" "It must be not serious." Say a few words, let the children remember 'doing homework seriously'." Just because of carelessness, is it really so simple? Let's first open the children's homework and look at a mistake.
Count, there are a few fish in the sea. A total of 9 yellow croakers, 8 octopus and 7 flat carp were painted. In the eyes of adults, this is a simple topic, but there are still a few children who are wrong. There are 5 people with the wrong number of fish, 4 people with the wrong number of flatfish, and 2 people with the wrong number of yellow croaker. The teacher found that a few wrong students also painted a mark similar to the number on the side of the fish. It seems that they are also very serious, saying that they are not serious enough to pass. What is the reason? When correcting the homework, the teacher asked the students: "How can I leak? How can I do it without leaking?" Some said, "I didn't count in order, so a few." Some said, "I am in order. "But I didn't make a mark, so I got more." "Well, I didn't make a mark, so I lost it." "Teacher, I made the mark, but I didn't order it, and it leaked." The teacher helped the students find the cause of the error, which is not the child's counting method. Many teachers and parents encounter such problems, but simply advise students: "Too careless, you have to be careful." Didn't find the reason, just remind or blame, what's the use?
Reason one: the impact of life experience
In the first-year language practice, there is a word-filling question: Mom gave me a piece of clothing, and my mother’s () is really good. Two brackets are required to be filled with "hair" and "hand" respectively. Obviously, this question should distinguish between the "hair" and "hand" glyphs. There should be no difficulty, but there are still children who are wrong.
The teacher called the child who made the wrong question to the side and asked him to read the words "hair" and "hand" first. He read it very loudly, yes, it was correct. Then why is it wrong? The teacher asked him to read the sentence with the words aloud. "Mom gave me a handcloth, my mother's hair is really good." "Do you think it is right?" The teacher asked him, the child looked blank. I don't know where I am wrong.
The teacher pointed to a white sweater he wore and asked, "What is your dress? Hand or sweater?" The child thought for a moment, first shook his head, and then gave the teacher an answer." This is white clothes." The teacher immediately understood that the student did not know what the "sweater" meant. The accumulation of children's life is so rare that even a common word like a sweater does not know! Such an example, but is ubiquitous in the first grade.
Reason 2: Interference with existing knowledge
In the first grade, there is a content of "knowing the renminbi". Some children are always wrong with the conversion of "Yuanjiao": 1 yuan = 60 horns = 60 points? Some parents are worried, so careless, so simple will do wrong, not to mention other topics; some parents are very calm, money problems are not like others, when grown up, who else will not use money What?
The error in the conversion of the Yuanjiao is related to the life experience mentioned above. Allowing children to touch coins and use coins in their lives can improve the ability to convert Yuan Yuan points. But now the small amount of money is too rare. Many children have never used a 1 cent coin. Shopping in the supermarket is also rounded off, not looking for a few cents. The angular conversion component has little practical significance in life. It is reasonable to say that in the above example, 1 yuan = 60 corners should not be wrong. Why do students who frequently use coins in high numbers make mistakes? It turns out that there is already a disturbance of the "time, minute and second" knowledge to the learning "yuan angle". There are many people who disagree with the unit time of the first-grade semester mathematics textbook. I have just finished learning the numbers within 20, I haven't learned the carry-in addition within 20, and arrange the 60-minute time, minute and second, which will bring confusion to the children who just touched the arithmetic: how sometimes it is full of 10 into one, sometimes it is Full 60 into one? These problems are nothing for adults and are very nerve-racking for first-year children. This effect still exists for the "yuan angle" that is learned after a few months. The only way is to strengthen it in life.
