Miami Dade College Announces 2021 Endowed Teaching Chairs

Miami, Nov. 15, 2021 Nine outstanding Miami Dade College (MDC) faculty have been named 2021 Endowed Teaching Chairs, the College’s highest faculty honor, and will be recognized at an awards ceremony at 5 p.m. on Tuesday, Dec. 14, at MDC Wolfson Campus in downtown Miami.

Donors generously fund Endowed Teaching Chairs through the ongoing work of the MDC Foundation.  Each year, top faculty are selected by their peers for this special award, demonstrating excellence in teaching and commitment to MDC’s mission.

More than 300 MDC faculty have been recognized since the Endowed Teaching Chair Program began in 1992, when MDC blazed the trail nationally with this type of recognition program at colleges. These programs had traditionally existed at universities. Endowed Teaching Chairs receive an annual stipend of $7,500 for three years to explore new teaching methods, develop new projects, and enhance their technological expertise.
