ACCORDING TO THE GLOSSARY OF EDUCATIONAL REFORM, THE TERM PERSONALIZED LEARNING REFERS TO A DIVERSE VARIETY OF EDUCATIONAL PROGRAMS, LEARNING EXPERIENCES, INSTRUCTIONAL APPROACHES, AND ACADEMIC-SUPPORT STRATEGIES THAT ARE INTENDED TO ADDRESS THE DISTINCT LEARNING NEEDS, INTERESTS, ASPIRATIONS, OR CULTURAL BACKGROUNDS OF INDIVIDUAL STUDENTS.
Notice that it never mentions a specific way that you must do this or that you must use technology!
The way I see it, you only need to do 2 things to personalize learning: 1. Engage students 2. Use formative assessments to differentiate instruction
