Comparison of four teaching methods on Evidence-based Practice skills of postgraduate nursing students.

The aim of this study was to compare four teaching methods on the evidence-based practice knowledge and skills of postgraduate nursing students. Students enrolled in the Evidence-based Nursing (EBN) unit in Australia and Hong Kong in 2010 and 2011 received education via either the standard distance teaching method, computer laboratory teaching method, Evidence-based Practice-Digital Video Disc (EBP-DVD) teaching method or the didactic classroom teaching method. Evidence-based Practice (EBP) knowledge and skills were evaluated using student assignments that comprised validated instruments. One-way analysis of covariance was implemented to assess group differences on outcomes after controlling for the effects of age and grade point average (GPA). Data were obtained from 187 students. The crude mean score among students receiving the standard+DVD method of instruction was higher for developing a precise clinical question (8.1±0.8) and identifying the level of evidence (4.6±0.7) compared to those receiving other teaching methods. These differences were statistically significant after controlling for age and grade point average. Significant improvement in cognitive and technical EBP skills can be achieved for postgraduate nursing students by integrating a DVD as part of the EBP teaching resources. The EBP-DVD is an easy teaching method to improve student learning outcomes and ensure that external students receive equivalent and quality learning experiences.
