The PDI chart was created for a reason: to clarify the differences in these terms. In 2010, the National Ed Tech Plan defined all three of these terms as they are related to instruction. So in 2013, Kathleen McClaskey and I needed to emphasize the differences: Personalization is learner-centered. The other two, Differentiation and Individualization can be teacher-centered. Yet, in many lessons, a teacher may be addressing all three of these approaches. You may be arriving at this page from our Slideshare page with the PDI chart.
In 2017, Kathleen and I decided to close our business, Personalize Learning, LLC so we could go in different directions. I was receiving so many questions and concerns about the chart and what that meant for their teaching practice. I invited over 100 educators from around the world to be part of a focus group to review the chart and other resources.
I created a new page on the Teaching and Learning Approaches chart and the details here. https://barbarabray.net/2018/05/22/teaching-and-learning-approaches-chart-v1/
