Hi Hannah,

Thank you for sharing your views about interactivity. You have emphasized the importance of student interactivity. Mere teacher-student interaction is not enough for students to master all the knowledge. Students can not make sure whether they have acquired everything taught by the teacher. By contrast, through interaction with peers, we can find out our weaknesses in learning, learn many different perspectives, and also absorb new learning approaches. Such a process is also meaningful and can compensate for the original teacher-student interaction.
