In this article, the authors reflect upon, revisit, and rethink the original guidelines for using digital technologies to prepare social studies teachers in an effort to facilitate theoretical and practical discussions that may serve as a foundation from which to approach the preparation and development of social studies teachers over the next few years. The authors revisit the guidelines for using digital technologies in light of current scholarship and current contexts. They conclude that 15 years ago they focused on the Internet and the materials accessible online. Since then, the authors have seen the emergence of more advanced technologies. All of these developments have played into the concept of 21st-century classrooms. As a result, they see great value in supporting teachers to develop the critically aware dispositions that enable them to be ready and engage with online professional learning sites.
