Abstract:

Critical thinking pedagogy offers a supportive environment for teaching ethics in the professional communication classroom. Four important aspects of critical thinking which particularly encourage ethical thought and behavior are identifying and questioning assumptions, seeking a multiplicity of voices and alternatives on a subject, making connections, and fostering active involvement. Focusing on these behaviors allows an ongoing incorporation of ethics into many different aspects of the classroom.
