Educational research has clearly defined the characteristics of the optimal introductory astronomy classroom – one where students are actively engaged in the learning process and frequently receiving timely feedback on their learning progress. This CAE/CATS Tier 2 workshop will explore a variety of technologies that enable instructors to engage students and efficiently provide feedback. Instructors will be trained and provided with curriculum materials from multiple NSF grants on computer simulations, computerized databases of Think-Pair-Share questions, and a library of both animated and pencil-paper ranking and sorting tasks. All materials will be disseminated through the web (http://astro.unl.edu) before the workshop and attendees will bring their own laptops with the software already installed.
