Embry-Riddle Aeronautical University's Bruce A. Rothwell Center for Teaching and Learning Excellence (RCTLE) provides professional development to the Worldwide campus’ majority adjunct instructor population. The RCTLE utilizes four professional development initiatives specifically geared towards adjuncts: required training for new hires and returning faculty, workshops and just-in-time microlearning, one-to-one consultations with instructional developers, and virtual faculty learning communities (FLC). These initiatives are intended to boost the quality of instruction in online courses, create an inclusive environment for adjuncts, and provide students with better support from faculty who are confident about teaching and use effective practices for learning.
