Hi, You have a great research: simple yet meaningful. I came across this one model (which I did while researching for a friends' research also) which I think, you can use. Find the Continuum of Knowledge Acquisition Model (Jonassen, McAleese, & Duffy, 1993). Since you can associate the 9 levels of instruction in teaching pediatric nursing, you may use this as your theoretical framework. Best Regards!
