The fact that she "scared them" in this way bothered me easily, as I wanted to try teaching in a regular class. However, on the other hand, I was happy (and I felt good about it) that even students from the standard group ("from the less gifted group") can enjoy mathematics and are able to work continuously. Even after the lesson, I was pleasantly surprised that I didn't mind at all that there was another person in the class who was still watching me teach.
