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. We needed to emphasize the differences: Personalization is learner-centered. The other two, Differentiation and Individualization are teacher-centered. Personalization or Personalized Learning means the learner is driving their learning. When the learner takes responsibility for their learning, teaching and learning changes. The roles of the teacher and learner change. We welcome you to share the PDI chart and use it for action research, professional learning, and to go deeper and clarify the terms so learning is deeper, relevant, and engaging.
The initial PDI Chart was published in January 2012. Version 2 was a revision about the differences between these three terms distinguishing that personalization begins with the learner who drives and owns their learning. The other terms are teacher-centered where the teacher provides the instruction, support, and assessments for the learners.
Kathleen McClaskey and I updated the chart to version 3 from your feedback. We needed to focus on Assessment AS, FOR, and OF Learning.
- Individualization involves assessment OF learning. This is where summative assessment is grade-based and involves testing to confirm what learners know and do not know.
- Differentiation involves assessment FOR learning and OF learning. This assessment involves time-based testing where teachers provide feedback to advance learning.
- Personalization involves assessment AS learning, FOR learning, and a minimal OF learning. This is where teachers develop capacity so learners become independent learners who set goals, monitor progress and reflect on learning. Assessments are based on mastery.
Now Kathleen and I are doing more on our own. If you plan to make multiple copies of this chart or use it in a publication, you can email me directly at firstname.lastname@example.org for permission.
