This workshop will provide you with a variety of research approaches, methodologies and instruments to help you understand the effect that your teaching with games is having on your students and their learning. Together, first, we’ll look at some typical (now stale) game-based language teaching projects and pull out and examine the thermometer(s) that were used. We’ll scowl angrily and “tut-tut” condescendingly at all the vocabulary tests and surveys about motivation or opinions from students and teachers. Next, we’ll gleefully break out the really cool research projects and research thermometers that we will borrow from the Ludic Language Pedagogy community kitchen. We’ll all “ooo and aah” at the mounds of shiny stuff: concept maps, gameplay transcriptions, debriefing sequences, stimulated recall protocols, student-created “best play” videos, evidence-driven reflections, textual and media analysis, ethnographic gameplay fieldnotes, transfer tasks, carefully chosen/created tests, open-ended interviews, and whatever else we can grab before the conference. You’ll receive on-the-spot training about how each gadget works (what questions it can answer and how best to use it) and learn how to stick a bunch of these things all over and in your Ludic Language Pedagogy (before, during, after, post) in order to clearly and comfortably get a hi-definition image of what effect your methods, materials and mediation (MMM!) have on your students and their learning. You’ll leave the talk/workshop with as many thermometers as you can cram into your inventory, and be ready to go back to your classroom. You will be able to use these tools to evaluate how well your own LLP is cooking and to make minor tweaks to it (iterate! try your recipe again!) the next time around (ala “good teaching” or action research) and you’ll be able to use the information and skills to more formally research your teaching and submit your projects to conferences and journals interested in teaching with games (*cough* https://llpjournal.org/ *cough*).
