At the beginning of the twenty-first century, there is a dramatic change in society. Teachers and educators are confronting the challenges of more accountability to fulfill the increasing demands of multicultural education in urban areas. Wise (2000) and Freire (1993) declare that society requires the development of an especially flexible, critical spirit when it begins to transit from one epoch to another. Teacher educators are becoming the change agents of critical thinking. The concepts of inference (abduction, deduction, and induction) and change agentry "ABCD" (Adopters, Black box, Change agents, and Domain) can be implemented in teacher education. Furthermore, teacher candidates can be encouraged to employ intellectual freedom to innovate and utilize new strategies with their students in the classroom. Inference expands teacher candidates' potential for critical thinking in a society of transition. Change management skills in ABCD keep them on the right track as change agents.
