The "Think Aloud" seminar is a group teaching method to assist pediatric nurse practitioner students to develop critical thinking and clinical reasoning skills. Seminar proceedings simulate the iterative clinical reasoning process that occurs in an actual clinic or office visit. Students' requests for subjective and objective data must be followed by the rationale as to why the information was requested. This method is effective for teaching and evaluating students' skills in differential diagnosis and management of common illness in children. The process will be demonstrated with the presenting symptom of a sore throat followed by a description of the procedures that are used. J Pediatr Health Care.
