Emeritus Professor Stephen M. Ritchie is passionate about enabling learners to achieve success. Searching for new ways to engage learners so they may develop essential literacies for the real world has been his focus. Accordingly, he has led several nationally funded research projects on the emotional engagement of students for learning science and the emotional experiences of beginning science teachers. He was the Editor-in-Chief of the internationally ranked research journal: Research in Science Education from 2008 to 2012. Before becoming a teacher educator, he was a science teacher for 12 years. He was the Dean of Education at Murdoch University, Australia from 2013 to 2018, and Acting Provost for more than one of those years (2015-2016).
