Notas del editor
- Being trained as a kinesiologyst and neuroscientist the general aim of my research is to apply the scientific method and the underpinning research methodology to generate evidence which can then be used to build simulation augmented education programs
- I will do this by first introducing the past med education models that are rooted in the principles of apprenticeshipNext I will introduce SimulationAfter that I will present samples of research that look at the optimization of various components of Simulation. Specifically, I will look at evidence that can help us decide what simulators to use, how we should train the teachers or educators, and how the courses which utilize simulation should be organized.Finally I will talk about a few possible future direction
- For that I will use anon-going study that looked at the use of simulation for the adherence of hand hygiene protocols
- What we normally want to know is wehther our programs impact learning of skills, which then lead to change in behavour, which can be measured in the clinical setting. This is what is known as transfer to practice. However,
- Typically what we assess is whether the learning happened based on what the learners know. When we don’t see transfer to practice, we cannot say whether this failure is due to ineffective education or transfer to practice mechanisms. Using simualtion ….
- … for assessments ofcompetnacy and proficiency at a skill can help us in the understanding of the low transfer to practice phenomenon.
- In this study …..
