Examples of typical viewpoints in interview materials.

Role of the interviewees	The topics	Examples of the typical viewpoints
Secondary school students	Autonomous expression	“Express the ideas according to different occasions.” “Some words are more appropriate to say through WeChat or QQ chat software than face to face.” “Hope to express my own unique views, do not like what others say.”
	Problem solving	“I usually solve the problem by myself through the Internet. If I cannot solve the problem, I will ask other students, sometimes I will ask the teachers.” “I’ll ask my mom for school supplies and my dad for money to go out.”
	Behavior regulation	“I make plans for myself.” “Sometimes I search for the information online, but I get drawn away by other information.” “I cannot help playing with my phone.”
Parents of students	Problem solving	“My daughter’s network skills are better than mine, and she would buy gifts for me from the Internet.” “I usually do not have any demands for children’s housework, laundry, and cooking;” “When I’m busy, my child will order takeout and hail a taxi on his own, which I feel relieved about.”
	Security defense	“I am quite confused about the use of the Internet. I hope my children can learn more extra-curricular knowledge through the Internet, but I am afraid that my children may come into contact with bad people or things on the Internet, and I do not know how to prevent and control them.”
	Parent–child relationship	“I had argued with my kids, but she still told me what happened at school when she got home.” “I think the children still care about me. They will ask me what is wrong when seeing me unhappy.”
Secondary school teachers	Autonomous learning	“In class, I advocated students to study independently and let students draw their own mind maps.” “Nowadays, students have a wide range of knowledge. When students answer questions, they cite some examples that I do not understand. They all say that they learned by themselves on the Internet.”
	Relationships maintaining	“Some students often take the initiative to chat with the teacher. When there is no question to ask, they will find other topics and will take the initiative to make fun of the teacher. They are very good at watching the person’s every mood.”
	Problem solving	“Nowadays, few students dare not ask questions, and they have a strong sense of rights protection. If the teacher stayed in other classes for a long time during the evening self-study, they will raise opinions.” “Students with good grades will only listen to what they want to hear in class, will not listen to what they think they can do, and will write other papers.”
