Aim. This research explores the use of clinical simulations as a platform for stimulating critical thinking in nursing students. Background. This study takes place in an associate degree nursing program with a clinical group of nursing students. Method. Utilizing a faculty partnership approach, information was presented to the clinical group. Students were divided into small groups to create simulation scenarios. Results. Students were able to appreciate complexity of care and research differential diagnoses as they applied to care and management of changes in client condition scenarios. Conclusions. Use of a small-group teaching method to develop, implement, and critique clinical simulation scenarios facilitated critical thinking and clinical judgment of nursing students.
