If you take into consideration Vygotsky's theories of cognitive development, you will understand that children have various ZPD. As children develop their affinities and as they build their own experiences they become more capable of connecting to content being taught. Because no two children (or people for that matter) are exactly alike, no two children will learn and benefit from exactly the same kind of care. While incorporating many different methods of care, learning and development would increase and so would the likely hood of achieving excellence. Don't forget to use Bloom's Taxonomy & look into Mel Levine's research of neurodevelopmental constructs. --Best of luck on the hw!
