"Differentiated Instruction is teaching with the child in mind rather than adopting a standardized approach to teaching and learning that seems to presume that all students of a given age are at the exact same place academically. DI is responsive teaching."
A great website for information, research and tools is Tech4DI.
Another great resource can be found on Cool Tools for 21st Century Learners. It is a presentation that provides planning tools as well as tools for differentiation.
Technology is an integral part of students' lives.
Experience has enlightened us to know that relevancy affords for student interest.
I cannot think of anything more relevant than technology: Tablets, computers, apps and more!!!!
