Constructivism is a learning theory widely used in the 21st century, which emphasizes learner are active and social interaction play an important role in leaning(Bruning, Schraw,&Norby,2011).
The development of Constructivism
The development of Constructivism is divide two periods, the first stage called First wave constructivism, which is announced by Piaget(1896-1980), a famous psychologist.Piaget’s psychological(cognitive) constructivism concern about individual perspective, and Piaget believed in the logical and construction of universal knowledge that can not be learned by environment(Mlller,2011), moreover, Piaget believes in social transmission is an essential part but could not affect people deeply(Moshman,1997), and the first wave constructivism can expand on “Radical constructivism”- knowledge is assumed to be the individual’s construction, it cannot be judged right or wrong(Woolfolk,2016).
The second stage called “Second wave constructivism” which mainly is consisted of “Vygotsky(1896-1934)’ s social constructivism”. “Vygotsky’s social constructivism” believed in development and learning are shaped by social interaction, culture tools, and activities. It could bond physical constructivism and social constructivism, for example, “The zone of proximal development” is an area that children could solve the problem with help from who it is more capable of knowledge ,and is also a place culture and cognitive interact with each other(Cole,1985).
The student-centered teaching method in constructivistivism
There are various types of learning theories in the constructivism, however, they still get focal characteristics influences all learning on the constructivist model , which are displayed in Figure 1 (Brunning, Schraw, & Ronning,1995).

The student-centered teaching method is one of constructivist theories, which is the mainstream view in the pedagogy recently, it could give students kinds of a chance to learn, because Student-centred class is dynamic construction of knowledge and students could learn it from social interactions by culture tools.
In constructivism, the student-centered classroom could build “Complex learning environments”-“problem and learning situation that mimic the ill-structured nature of real life(Woolfolk,2016)” for students and give them authentic tasks to accomplish. Then, students could learn knowledge from peers or teachers via social negotiation-one of social interactions. It also emphasizes making students build awareness of active learning role.

I like the idea of student-centered education very much. Students are the main body of learning and should be guided and educated by paying attention to the different talents of each child. Traditional education is too depressing and burdensome for students. Learning should be a pleasure thing rather than a pain thing. I think. Being student-centered allows students to see more possibilities for themselves and learn happily.
