Short version: This week I had a couple of students in the lab for work experience, and it reminded me how much I enjoy teaching. Some thoughts.
One of the joys of my education was being repeatedly challenged to answer questions that I didn’t know the answer to. I found this an incredibly powerful way to learn both information and problem solving skills. It requires capable teachers with time to be able to explore each student’s individual thinking, as well as confident students.
Students are used to being tested on content they ought to have learned, being praised for preparing and chastised for a lack of practice. Thus it can be disquieting for them to be confronted with a question they have not prepared for. Post-education this is not very useful when working in science, where questions need to be answered that have not been answered before.
A wonderful example of taking relatively common experiences and following a path of questions and answers is “Fun to imagine“, an armchair conversation with Richard Feynman.
Science through fresh eyes
There is an XKCD comic for many situations, and one such specific situation is that there will always be many people who have yet to learn something you take for granted. In the lab, my team and I get to take for granted the understanding of many scientific concepts. However, through the eyes of inexperienced students the mundane becomes new. This is easily seen as a weakness of the students, but it is also joyful to see tools and ideas I take for granted be seen as exciting and new.
A good example of this is Pendulum Waves, which was demonstrated at the Cowley Carnival (see below).
If you play these games of asking and attempting to answer questions, often your guesses will be wrong. In order to persist and learn you must enjoy the game, and therefore you must be able to enjoy being wrong. CGP Grey summaries it well: “if you want to always be right, you have to always be prepared to change your mind”.
