Charles Schwahn: Mass Customized Learning (MCL) is actually a very descriptive label. From a learner’s perspective, MCL means that “every day when I go to school, I am met at my individual and personal learning level, I am able to learn in my most powerful learning modes, I am motivated to want to learn with content that is of interest to me, I feel a sense of challenge, I am successful, and I look forward to returning to school tomorrow.”
