A Personal Learning Environment (PLE) it is a combination of tools (usually digital) and resources chosen by the learner to support different aspects of the learning process, from goal setting to materials selection to assessment. The importance of PLEs for teachers lies in their ability to help students develop autonomy and prepare them for lifelong learning. New technologies are making the creation of PLEs easier and their use more effective. Although PLEs can be created without the aid of technology, in this article, author Hayo Reinders, Professor and Director of the online doctoral TESOL program at Anaheim University, considers their use mostly in the context of online resources. Here he also discusses PLEs' use for language learning and looks at ways in which teachers can use them to help students take responsibility for their own learning.
