This multiple case study involved five high school science teachers participating in a...

Effect of an Adaptive Thinking Training Methodology on Critical Thinking Disposition Using Human Patient Simulators: A Catalyst for Preparing Advanced Nursing Students

Robert Joseph Fitkin Jr.
Critical thinking decision making is the foundation for effective, safe, nursing practice. Nurses have to assess patient issues rapidly regardless of whether it is emotional, psychological, or physical, and then sort through "rapid fire" questions resulting in invisible sorting, discerning, and drawing of conclusions. Doing this "invisible sorting" well requires practice. Nursing education provides practice through preceptors or scenarios-driven human patient simulators to practice critical thinking. This study examines Adaptive Thinking Training Methodology with simulation...
