Teaching Experience:

2001 Lead Ecology Instructor, Columbia University’s Biosphere 2 Center,
Earth Systems Field School I (six-week ecology & geology field course for undergraduates).

2001 Graduate Teaching Assistant, University of Arizona (Animal Sexual Behavior, for non-science majors)
1997-1998 Graduate Teaching Assistant, University of Arizona (Ecology, Systematic Botany)
1994-1995 Graduate Teaching Assistant, University of Arizona (Intro Botany for non-science majors)
1978-1980 Graduate Teaching Assistant, Department of English, University of California at Berkeley

Educational Philosophy:

My approach to teaching science is to coach the students in teaching themselves through active learning (performing tasks and analyzing results), using demonstration and lecture only when necessary. Apart from being effective, this approach teaches students that science is a cycle of planning, trying, analyzing and then planning again, rather than a matter of absorbing endless facts and concepts. Even in a lecture-based class, examples can be presented as intriguing detective stories, with the instructor not revealing the outcome until they have asked the students to speculate on what was found. It is especially important to constantly remind students of how little is known, and how much more there is to discover about the natural world. Traditional lecture courses have the insidious and deadly effect of convincing the student that everything worth knowing has already been discovered. Stressing the unexplored generates excitement and raises the hope in the student that they themselves can make new discoveries, and that they do not have to wait until they are a professor to do so.

Another crucial task of science education is to teach students the difference between facts, opinions, and theories. Confusion about these distinctions are a large part of the understanding gap between the public and the science community. How a teacher approaches this depends on the stage of learning in the students. For example, students in the early stages of learning who see the world as right and wrong, are confused and annoyed by being presented with conflicting but potentially valid theories. Unless they are explicitly taught the distinction between fact and theory, they will jump to the conclusion, shared by many people in the public sector, that scientists never actually figure anything out, and that experiments simply generate conflicting evidence.

When I teach, I provide my students with feedback on how they are doing, and on how they can improve, throughout the course, so that the final grade is not a surprise. I also actively solicit feedback from them on how I am doing, so that I can correct shortcomings and oversights as early as possible. Unless it is an advanced course, I also try to spend at least some time teaching them how to be a better student in general. Amazingly, the study skills that are crucial to success in the academic environment are seldom taught. Most students figure out how to study by trial and error, but even those who are gifted with good concentration and memory can learn to more efficient and effective in their studies. When I taught the lab section for an Intro Botany course to a class of non-science majors, I included a brief "study tip" at the beginning of each lab -- how to take notes, how to read to remember, how to review material, including one of my favorite learning techniques: take a chunk of reading or lab work and turn it into a potential exam question.

Apart from the few who become scientists, most people only encounter real-life science in the classroom. That experience will color their impression of science from then on. The facts may fade, but if you teach them how scientific knowledge is created, how hypotheses are tested, and the difference between suggestive and definitive results, they can rely on that understanding for the rest of their lives.
