In this expository piece based on my Haimo teaching award presentation, I share three guidelines that drive my teaching: be informed, be courageous, and have compassion. Becoming an informed mathematics educator requires knowledge about evidence-based teaching practices, which can be acquired via mathematics education research and policy documents. Developing courage to teach with evidenced-based teaching practices entails a trial-and-error approach, and the willingness to ask for guidance from experienced faculty. Having compassion in teaching, requires more investigation, but I flesh out some personal practices that are supported by the literature.
