To further advance the notion, P21 created a Blogazine to "connect the dots between 21st Century skills and deeper learning outcomes".[20] The blog articles are written pro bono by major educational writers who advocate for the paradigm shift to Deeper Learning as well as by a balance of school leaders, teachers, professional learning specialists and others who are incorporating deeper learning practices into their curricula, instruction, assessment and system change plans. In its second year, the no-fee online P21 Blogazine expanded into a three times weekly online journal.
