Andrew Rate

My formal credentials include M.Sc. in Chemistry from The University of Canterbury in New Zealand, and a Ph.D. in Soil Chemistry from Lincoln University, New Zealand. I have worked at the University of Western Australia since 1995 as a Lecturer and Senior Lecturer. My research and teaching discipline is best described as Environmental Geochemistry, with expertise in the application of aquatic physical chemistry and surface chemistry to a range of fundamental and applied research problems. My main current areas of research interest and achievement are: Understanding the behavior of trace and rare-earth elements in soils, sediments, water, and regolith; sulfidic sediments and acid sulfate soils; urban soils and sediments. I teach mainly in Environmental Science, covering soil physics and chemistry, environmental assessment, and environmental statistics.

In the rest of my life I'm a husband, a dad to 2 great girls, science and geochemistry geek. Love (in no particular order): being outdoors, doing field work, doing multivariate statistical analysis, making sciencey maps, hanging out with my family, getting good data, my church, encouraging and teaching students, environmental and social justice, prog rock/metal, playing guitar, poetry, cycling to work, movies, coffee, . . .

Succinctly (but, to a purist, likely to be inaccurately) I consider myself an experiential teacher with social constructivist leanings. I believe in learning by doing, especially in the context of environmental science, and learning in a community where the 'teacher' is also one of the learners, and where the teacher's authenticity and character help to maintain an effective community of learners.

More specifically, I have been influenced by these books (among others):

Kahneman, D. (2011). Thinking, Fast and Slow. Farrar, Straus and Giroux, New York, NY, USA.

Palmer, P.J. (1998). The Courage To Teach. Jossey-Bass, San Francisco, CA, USA.

Siegel, D.J. (2013). Brainstorm: The Power and Purpose of the Teenage Brain - An Inside-Out Guide to the Emerging Adolescent Mind, Ages 12-24. Jeremy P. Tarcher/Penguin, New York, NY, USA.

My best teaching practices are inspired (but imperfectly implemented!) by the Learning Community model of Parker Palmer (Palmer, 1998). The other books are not really about teaching, but I think they're extremely useful for informing my teaching practice. Kahneman (2011) discusses the main categories of thought processes in humans, and his ideas on inherent bias are highly relevant to teaching science. This is especially relevant given that human brains are not mature until the age of about 24 (Siegel, 2013); older than most of the students we teach!
