In my opinion, without any interaction or any kind of debate about subject between students and
among the student and teachers, lesson can be think as a raw fruit since its quite important to be in a interaction among students during the lessons. It will improve their thinking strategies while debating on any topic.They will share their own ideas with friends. So it will improve their friends point of view in a good way.Constructivist approach is the way we can apply students and take feedback from them. The more they participate interaction with other peers, the better they will start to learn and understand the concept of that day's topic.They will complete their blanks by evaluating and having interaction among their self.
On the other hand , constructivist approach may be a negative effect on a students who is introvert person since he or she don t want to have a conversation with other student and want to do his or her study their self by applying without any sharing method. This can restrict their ideas and approaches on any topic. When I become a teacher, I can apply constructivist approach to my classroom since some students can have advantages of it ,however,I don't want to push some students to have this method.
