myTE: About Us

About Us

Despite the value of feedback, in clerkship alone, 70% of teachers do not receive feedback (MD Program, University of Toronto, Nov. 2022 newsletter). Dr. Esther Bui has been working to help teachers who face the feedback dilemma by developing an innovative evaluation platform for the fast-paced, clinical teaching environment. Dr. Bui believes that good teachers teach well, but great teachers learn well, especially when they receive timely, constructive feedback in an environment that sees and enables their full potential.

myTE is a simple, secure, universal platform that captures any teaching, anywhere, any time. In 30 seconds, teachers can open real-time pathways for meaningful, confidential feedback. myTE has 1200+ registered users globally and has enabled 10,000+ evaluations. As people learn about myTE, its utility is expanding to non-clinical (research) teaching, as well as to surgery, anesthesia, dentistry, nursing and allied health.

In 2022, myTE Professional was launched with significant improvements such as auto-generated QR codes, direct links and notifications, as well as portfolio creation tools and teaching metrics dashboards. These enhancements take on the administrative heavy lifting of the teaching dossier process to enable educators to simply teach and learn from timely and meaningful feedback
