Every day we meet, work with, teach, and learn from people who are potential change agents. Just think about your favorite teacher, and the impact that teacher had on your learning, or an attentive and innovative student in your classroom, and how that student took ownership of their learning. As teachers and as learners, our beliefs play a key role in the kinds of action we take. JALT2019 offers an ideal opportunity for meaningful discussions and lively debates about better ways to have a positive impact on learning and teaching. Herein lies the core of the theme for this year – Teacher Efficacy, Learner Agency.
