The purpose of the ADL Mobile Learning (mLearning) Guide is to provide a universal resource on all topics pertinent to mobile learning. This resource is intended to provide you with an introduction and will explore the following topics about mobile learning: the basics, planning, learning content, development options, and design considerations. This app was developed by the Advanced Distributed Learning (ADL) Initiative's Mobile Learning Team. ADL is sponsored by the Office of the Under Secretary of Defense for Personnel and Readiness (OUSD P&R). This is an official app of the U.S. Government ADL Initiative.
