Thank you for bringing up this topic! Indeed, technology is a great tool for implementing personalized learning, though it is an additive and doesn't replace great teaching in the classroom.
I would like to share with you a brief handbook (only 12 pages) called "Personalized Learning: A New ICT-Enabled Education Approach", published by the UNESCO Institute for Information Technologies in Education.
It is a thought-provoking document with practical examples of personalized learning. However, what caught my attention was the section on the benefits and risks of personalized learning.
Please have a look What is your opinion about it?
