Xiao Zhong residual leakage, who works in a publishing house, said that he worked as a teacher and a volunteer teaching assistant for several years. He said that the "negative problems" of network communication are mostly arranged in the extracurricular exercises of synchronous teaching in primary and secondary schools (especially primary schools).
"The counseling books that give these questions are mostly to introduce children's yin questions by expanding their thinking and intelligence.
Ms. Cha, a fourth-grade math teacher at Lhasa Road Primary School in Nanjing, said that she had met students asking them similar "negative questions".
Some problem-solving methods are too exaggerated, which makes teachers feel "excessive"
Teacher Ge of Lhasa Road Primary School in Nanjing bluntly said that "Yin problem" has no teaching significance at all, and she does not advocate that primary school students do too many unconventional math problems.
Take the "diamond problem" as an example. Teacher Ge said it was a graphic problem. The correct method to solve the problem must be to transform one figure into one or more figures, and the characteristics of the figures must be in them before it can be called a figure problem. Answering with "1" is not training the so-called "reverse thinking", but worsening the topic, which is a concept of stealing.
Teacher Ge thinks that often doing "dirty questions" may lead to students' obsession.
"Formal teaching should teach students how to solve problems. In order to tell students the method, we often spend two classes discussing a problem.
Step by step, teaching students in accordance with their aptitude is the basic law of education.
Just like every season has different scenery, each age group has its own ability to accept knowledge, understand problems and find problems.
Creative thinking ability, in particular, needs to be developed in advance, but it still needs to be developed step by step and accumulated over time, and cannot be over-developed. "Mr. Ge thinks that the' yin topic' is too abstract, which is not conducive to the cultivation of students' interest and is easy to mislead others' children.
A primary school olympiad math problem was spread on the Internet, and the strange method of solving it made a large number of netizens call it "insidious". Eight matches are placed in two diamonds, only two of them can be moved. How to turn two diamonds into one diamond? Answer: Move the two matches at the bottom of one of the squares and change them to "1" and "ge", which read together as "1".
The negative topic of "1" forwarded by hundreds of thousands of netizens on the Internet comes from the website of Xueersi Online School. In a video titled "Examples of Elementary School Mathematics Synchronous Full-Score Classes", a male teacher named Cui stood in front of the screen with "Weekly Negative Questions" written on the electronic blackboard behind him. In the video, Teacher Cui enthusiastically explained how to solve a math problem by solving a Chinese problem. When she finally got "1", Teacher Cui couldn't help laughing.
After watching this video, many netizens commented that the questioner was too "sinister" and the topic was dubbed "undisciplined" math problem by netizens.
