After more than 40 years in mathematics education, Mr Bob Dengate will retire from the Charles Sturt University (CSU) School of Teacher Education at Bathurst on Sunday 1 March. CSU Deputy Vice-Chancellor (Administration), Professor Lyn Gorman, praised Mr Dengate as a wonderful colleague who has made an exceptional contribution to the NSW HSC Online project since its inception 11 years ago. “Bob was a pioneer in developing online learning materials for mathematics education in the mid-1990s, when the NSW HSC Online website was one of the earliest quality-assured educational websites in Australia. He has contributed immeasurably over the years to fostering good relationships with the NSW Department of Education and Training and the NSW Board of Studies, which has been fundamental to NSW HSC Online becoming a major educational resource for upper secondary students and teachers. He has also made an inimitable contribution to Bathurst community radio 2MCE and to journalism education.”
