Alex Shum, a graduate student who is completing his PhD in the field of Applied Math, had shown his gift of teaching since he first joined University of Waterloo in 2008. Students acknowledged his ability to “turn abstract concepts into simply understood yet thought provoking examples”. His well-prepared lectures incorporated with various teaching methods are highly regarded by his students since it turned learning the challenging calculus course into an enjoyable experience. His students also remarked his genuine concern for each student’s progress and cheerful positive attitude. “Alex does not just teach math,” wrote by one of his students, “he creates an understanding of the uses and applications of calculus with examples which has an impact on the rest of our careers.” Alex’s passion and unique ability of teaching is admired by many other teaching assistants and has inspired them to seek for improvement of their own teaching.
