Public relations (PR) research on the teaching of critical thinking shows that PR practitioners must possess the communications skills and social sensitivity necessary to help organizations adapt to their environments. PR students must learn to think critically and to take an active role in learning. Practice in questioning educators' and researchers' conclusions will give PR students the opportunity to transfer critical thinking skills to functional communication situations. Possible critical thinking development exercises include having students: (1) decide which of a series of news releases, brochures, or annual reports are better written, more creative, etc.; (2) analyze PR approaches within campaigns; (3) locate examples of unethical PR materials; (4) explain the role of PR in society; and (5) develop a PR campaign for a dummy corporation. In using PR textbooks, the teacher should encourage students to ask questions about what they read, seek sources of information, examine solutions and suggestions, question their own beliefs, evaluate research findings, and question definitions. Students should be rewarded for trying to improve their thinking skills. (SG)
