She used special techniques in her teaching to stimulate children's interest in learning, such as playing music for students to listen when students didn’t have distractions, giving extra points for students who intend to learn, using media teaching such as PowerPoint.

Everything the teacher does can make the student not feel bored in this subject. It also urged me to want to teach.
