Hello, the movement of the elevator is indeed a translation movement, but the concept of translation has never been touched in the third grade of primary school, so I think the teacher's intention may be to let the children judge whether the elevator is doing horizontal movement, but the two concepts of translation and level are not too confusing, so it is written as translation movement.

So I think the teacher must give a reasonable explanation to this problem. If the teacher is wrong, the teacher should admit that if the teacher has his own ideas, he can also talk about them together, so that children can't have wrong ideas, which is not very good for their knowledge growth.

It is also appropriate for teachers to discuss their own ideas. Admittedly, one of the respondents said it better. "Sitting" in the elevator, the movements of people sitting in the elevator are actually static, relative to the elevator, and the elevator itself is moving. However, this seems a bit far-fetched. The math problem in the third grade of primary school looks a bit like talking about words, and the third grade of primary school has not learned a relatively static one. .......
