Brown and Chronister, of the University of Akron, seek to determine whether nursing students who received high-fidelity human simulator (HFHS) experience along with a didactic ECG course would have improved critical thinking and self-confidence compared to students who only received didactic content. Bennerâ€™s novice to expert theory provides the theoretical framework for this study. The researchers measured their hypothesis with a â€œcustomized, computerized, multiformat examâ€ and a researcher developed tool (p. 46). Operational definitions of critical thinking and self-confidence are provided. Ultimately, critical thinking was not significantly increased from the control group, but self-confidence increased after HFHS experiences. Yet, numerous limitations require that these results be considered carefully.
