Success:
1, with distinct levels and situational guidance, stimulates children's desire to explore.
2. The operation process has clear guidance, from easy to difficult, and goes deep at different levels to achieve the goal smoothly.
There is a problem:
1. When setting the scene, the imaging problem of the haha mirror is ignored. This problem has been considered when designing this scene, but no better method has been found. I just wanted to apply this principle at that time, but it was not rigorous enough. )
2. When guiding children's operation, the problem of imaging (overlapping) after two plane mirrors are placed in parallel is ignored. Although no child has raised it, as a guide for children, it is still necessary to explain it properly or introduce it briefly.
Through the tempering of this teaching activity, I have a deeper understanding and understanding of the organization of scientific activities, and I will be more rigorous in the process of organizing scientific activities in the future.
