Using an expanded version of Alexander's (2008) theory of dialogic teaching developed by RojasDrummond, Torreblanca, Pedraza, Vélez, and Guzmán (2013), this case study explored how instructors and students in a hybrid graduate course engaged in the process of dialogic teaching and learning (DTL). In particular, we examined the ways in which scaffolding strategies used in the course supported inquiry-based learning. Our findings suggest that instructors and students engaged in all five dimensions of DTL as defined by Rojas-Drummond et al. (2013), and illuminate the ways in which scaffolding can facilitate inquiry-based learning in interdisciplinary instructional settings.
