How do you comment when a teacher makes a mistake in a public class?

You can write on the evaluation slogan that the teacher needs to pay attention to accuracy in very few places to ensure that the quality of the class is infinitely close to perfection.

Generally speaking, you can refer to the following to comment on the shortcomings of open classes:

The atmosphere in the entire class is not very active, students are not very excited, and they are a bit reluctant to let go in class.

In classroom teaching, the teacher did not set up a situation suitable for students to learn, resulting in an incoherent teaching process, with few teacher demonstrations and no opportunity for students to show off.

Teachers did not promptly help students solve safety problems that occurred during exercises.

In terms of the content arrangement of this lesson, it is best to reduce the content of the lesson by one activity, otherwise the teaching time will be a bit tight.
