The advent of postmethod encouraged much debate over the concept amongst researchers from different approaches. One approach was the concept of "teacher metamorphosis," which posits that teachers should perform different roles and hence, "teacher metamorphosis" is considered a possible remedy for certain criticisms of postmethod. Although this metamorphosis is a solution that seems tenable, there remain many questions regarding its practicality. Considering that those who are most directly connected with the concept are teachers, the present study investigates the practicalities of "teacher metamorphosis" from teachers' perspectives. To this end, ten teachers were selected and interviewed about their beliefs on "teacher metamorphosis." Data analysis reveals that almost all the interviewed teachers agreed that there is a need for "teacher metamorphosis," although they also agree that there are barriers including financial barriers, respect barriers, time-constraint barriers, and incentive barriers that encourage teachers to resist metamorphosis and that, therefore, needs further consideration.
