Observation location: Yizhi District
Observation time: random observation
Observation object: Liu X.
Observation process: chopsticks were recently placed in the puzzle area, and the activities of holding objects according to numbers were carried out in combination with the math box in the puzzle area. I play with them in order to instruct the children how to use chopsticks. I said, "I'll clip it first", so I put a small ball in the box of "1" and the other children took it in turn. By the time Zhao arrived, it was the last number "6". I asked, "What is this?" Chen Yuan said "yes 8", the other children said "no, no", and Chen Yuan said "yes 9".
I asked Liu Chang next to me, "Is he right?" Liu Chang blushed and said nervously, "I don't know". So we recited the digital nursery rhymes again. Chen Yuan changed them, and we continued to edit them.
Analysis: Chen Yuan is outstanding in various activities. He has a strong ability to accept and loves to use his head. I wanted to guide Liu Chang, but Liu Chang's concept of logarithm is very vague, so I usually give him more guidance, but I move around in the corner.
I found that Chen Yuan's logarithm (I think he knows it very well) is still vague and confusing, which also shows that some children's understanding of logarithm is not very clear, which is not easy to find in group activities, because children are easy to imitate and follow the crowd in group activities, so that teachers can't fully understand each child.
Measures: strengthen the understanding of numbers in all aspects of life, observe children more in regional activities, guide children to understand the practical significance of numbers, and make effective records. In group activities, fully understand the development level of each child, change materials in the puzzle area, enhance interest and improve children's learning enthusiasm.
