I am the strongest sheriff on the surface

"Oh?" Dong Miao showed a provocative look, and said, "Father Nannan, what do you think I said is wrong, just speak up, and different opinions are allowed in my class."

The surrounding parents all turned their heads to look at Xiao Cheng.

Xiao Cheng sneered, and said, "First of all, I don't think these questions have any practical significance!"

Parents are whispering to each other...

"Ah? What does Papa Nannan mean?"

"I think these questions are good?"

"If you don't answer, you will be angry from embarrassment!"

"Really, who is this? I haven't had a class for a long time, and I just listened to him talking nonsense."

"Yeah, you can do whatever the teacher says, there are so many things to do!"

"..."

Dong Miao on the podium was also somewhat disapproving: "Oh? Papa Nannan, please tell me your reason."

"Okay, I'll explain it to you carefully!" Xiao Cheng said bluntly: "These questions are said to develop children's mathematical thinking, prevent them from developing inherent ideas, and be able to solve problems creatively. The original intention is good, and the topic seems to be fairly novel, but in fact it is just the opposite."

Xiao Cheng's words were resounding: "Not only did it fail to form a good way of thinking for the children, but it solidified their thinking mode and led them all to the wrong path!"

Dong Miao wanted to say something, but Xiao Cheng waved his hand: "Listen to me first!"

Then, ignoring other people's reactions, he continued to say loudly: "First, in terms of problem-solving ideas, whether it is at the current stage, or in elementary school, middle school, university, or even in the future for scientific research, the first thing that comes to mind is to use mathematical laws to solve problems. Solve mathematical problems instead of finding solutions from other disciplines."

"Mr. Dong, look at these questions. Except for the second question, which is normal, what are the other two questions? Brain teasers? Is it possible to cultivate children's correct mathematical thinking?"

"If you don't believe me, think about it. For the first question, which theorem can you use to prove that 1=4? Or do you want to come up with a new mathematical conjecture?"

"There is still a third question. Do we need to use Hanyu Pinyin when solving math problems in the future?"

"And how many children in the class can figure out what you call the correct answer by themselves?"

After speaking, he glanced at Zhuang Zhuang's father.

At this point the classroom was completely in chaos.

"Nannan's father seems to have a point."

"Yeah, what's the use of those two brain teasers?"

"No, let a child who hasn't gone to school do the answer that we adults can't think of. I really don't know what to think."

"But what does he mean by solidified thinking?"

"I don't know, just listen to him."

"..."

The parents have already started to lean towards Xiao Cheng's argument, only Section Chief Wang's face is not healed.

He came up with these two questions, and he has always been proud of them.

Xiao Cheng didn't care about the noise around him, and still said loudly: "Think about it, when children encounter similar math problems in the future, what they think of is not mathematical theorems and formulas, but Chinese pinyin, staff scales, and reading comprehension... How is this so? Horrible thing!"

"The point is, these so-called innovative questions all have a standard answer. Teacher Dong, please answer me as a math teacher. For the first question, is it wrong for Nannan to answer 4=16?"

"What about the second question? Is there something wrong with the distribution method Nan Nan said? Dad plus four children, isn't it fairest for each person and one cake?"

"Even if it's the third question, your standard answer is D, which is sorted by pinyin tones. What if I sort by the equation on both sides?"

"That is to say, there are a total of 7 numbers. I use the number 7 as the middle number. The first three numbers 10, 5, and 2 add up to 17, and two of the last three numbers are 9 and 6. Then I fill in the brackets. 2. If the sum of the three numbers on both sides of the number 7 is 17, then the answer is option B corresponding to the number 2, can you say I am wrong?"

Xiao Cheng's words were deafening, whether it was Dong Miao on the podium or the parents and classmates in the audience, they all looked at him dumbfounded and speechless.

"Yeah, everything has a standard answer, and it's wrong not to answer according to the answer in the textbook. Is this scientific?"

Xiao Cheng spoke more and more vigorously, and couldn't stop at all: "The most outrageous thing is that there is even a standard answer for reading comprehension, which is simply ridiculous!"

"Excuse me, you said that Shi Xian's poems come back after all the money is gone, and I said he is a prodigal son. Can you say that I am wrong?"

"Mr. Lu Shuren said that in my back garden, I can see two trees outside the wall, one is a jujube tree and the other is also a jujube tree. You say that writing like this can create a more monotonous and lonely atmosphere. I He just said that Mr. just wrote it casually, without that meaning at all, can you say that my understanding is wrong?"

"There are too many examples of this. After reading a piece of text, everyone has different experiences and moods, and they will have different opinions. Are they all wrong?"

"Even the author's state of mind at the time of creation, those so-called standard answers, aren't you guessing? Are you the roundworm in someone else's stomach?"

Looking at Xiao Cheng, who was blushing and thick-necked, Dong Miao felt a little helpless: "Father Nannan, you are a bit biased. Besides, aren't you being ridiculous? I can't help you if you insist on saying that."

Hearing what Dong Miao said, Xiao Cheng jumped up.

"What arguing? Isn't every development of science and every progress of human society produced in questioning and arguing? Could it be that they are resting on their laurels and are produced in standard answers?"

"If this goes on, can it be better?"

As for what could be wrong, Xiao Cheng didn't say clearly.

The parents bowed their heads and thought for a while, and they all started muttering to each other...

"Oh, how come the more I listen to Nannan's father, the more reasonable it is?"

"I also think so. If you want to improve, you can't rely on this method."

"Not to mention, I think about it carefully, the little girl's answer just now is really not wrong."

"It's not going to end well this time..."

"..."

Dong Miao on the podium bit her lip and thought for a while, she seemed unable to think of any way to refute Xiao Cheng, but she still said stubbornly: "You say these topics are not good, so can you tell me what mathematics knowledge these preschool children should learn?" ?”

Xiao Cheng was amused by her expression of "you can do it, you can do it": "I said that children of this age should focus on cultivating their interest in mathematics. For example, tell them that the thickness of the ice surface can be calculated. That way they'll know when it's time to go ice skating on the lake!"

"For example, tell them that the reason why airplanes can fly into the sky is that mathematics is indispensable!"

"For example, the cartoons they love to watch, the production process includes the application of mathematics!"

"For example..."

After citing several examples in a row, Xiao Cheng continued: "This is the mathematics knowledge that these children should know, so as to cultivate their strong interest in learning mathematics, instead of the weird standard answers!"
