Reflections on a Wrong Question of Position and Direction (1)+Unit math diary Sharing
? In today's exercise, I found that many students fell into this problem. Because they corrected and commented immediately, they didn't look carefully, thinking it was just difficult to determine the child's orientation. After I found that many children made the same mistake, I stopped to analyze the reasons for the mistake. It turned out to be a child's mindset, and I didn't look at the problem carefully. I also decided to solve the problem in the direction of "up north, down south, left west, right east" on the general plan.

? In class, I specially chose the homework of these two students to show. The following is a class clip:

? Teacher: Children, these two students have done something wrong. Can you analyze them? Why did they do something wrong? Talk at the same table after thinking.

(Not long after the communication, several schoolmasters in the class have their hands in the air, and these hands are usually left and hung by me in class, so I give as many opportunities as possible to middle school students or students with learning difficulties, and most of them play a supplementary or corrective role. )

? Slowly, more than half of the children raised their hands, and I invited Yu Huang and Hong Kai.

?

? Hong Kai: I can see the problem at a glance. The title says that Qi's back is east, so his front is west, his left is south and his right is north. They made a mistake because they didn't look at the topic and directly decided that the direction was "up north, down south, left west, right east". This is our idea. Do you have anything to add?

? After the whole class shook their heads, they applauded automatically!

? Teacher: What do you want to remind other students from this question?

? Yang Xinda: We should carefully examine the questions.

? Hong: Not all directions in every question are "going north, going south, left west and right east". It should be analyzed according to the question type.

? Teacher: It seems that these two students know each other very well! Yes, it is very important to examine the questions. Maps are usually made according to "up north, down south, left west, right east", but not all directions of every problem are like this. We need to read the questions carefully and make sure.

? Thinking after class:

? The biggest reason for the high error rate of this question is that students are influenced by thinking patterns. First of all, students' mastery of typical problems is not rich enough to be "well informed", so they generalize familiar problems and blindly apply them, which leads to mistakes in solving problems. Secondly, students are not flexible enough to think and seek the opposite sex, so they can't analyze specific problems, which leads to wrong judgment.

? In the future teaching, we should closely follow the requirements of Curriculum Standards, rely on "team learning", let students think more, talk more and ask more questions, truly implement the "student-oriented classroom" and make students' thinking come alive. In terms of homework design, we should pay attention to less but better, and the topic thinking content is big, avoid mechanical memory problems, and strive to "reduce the burden and improve the quality"!

? Let's share the math diary (1) of the students in the position and direction of this unit:

? This is the first time that the children in the class have written about math diary. When I mentioned math diary to my children yesterday, everyone shook their heads assiduously, which shows that writing is not a happy thing for most children. I specially found several articles about math diary on the Internet to share with my children, emphasizing that I only need to write my own gains and feelings, and the number of words is not limited.

? It is still a surprise to put it away today! Although most children are just imitating the contents of online diaries shared yesterday, as Teacher Xiao Chen said, "Just start", if you persist in doing one thing, you will always get something.
