I like to approach chemistry as a different language, because it used symbols to convey ideas across, but they are not the reality.  When we draw a little stick structure, alcohol does not exist as I’ve just drawn it, it’s a representation.

I find it [teaching] enjoyable, and I think that if you’re enjoying teaching something then your passion and desire and enjoyment gets transmitted to the students.  It’s not necessarily easy to teach, but it’s satisfying and generally we want to inspire them to increase their level of intrinsic motivation to want to continue to study chemistry.

I find that some students pick up what the mole concept is from the idea of grouping numbers of things that are every day size. 

When they come in I give a very simple quiz which we do using clickers, the sort of anonymous audience response systems, and I just test a few multiple choice questions, just testing their understanding of some of those terms and then when I notice that there’s, well, anything more than 10 or 15% of students who don’t correctly understand those terms then we go through a process of exploring what those terms are and why they apply to what they apply to and then I retest that a couple of weeks later.... I notice at the end of the year some of the students can lapse back into their old habits, so it’s something that I am going to need to think of continuing to reinforce.

A lot of it is from colleagues.  Conferences are fantastic.  You know, your chemical education conferences.  I do go to a lot of those.

Ions and ionic chemistry are essential to life and just about everything they will run across.

This understanding builds students' knowledge about the basic structure of matter which stimulates them to think in sub-microscopic level that provides the fundamental understanding for further chemistry learning.

So you shouldn’t be rigid, you shouldn’t be rigid in what you’re going to do.  It’s always stunned me that people say you should know where you start a lecture and where you’re going to finish, and if you get to that point and you finish ten minutes early you then should just finish.  I’ve never worked on that principle.  I never know where I’m going to start because I never know where I’m going to finish, right.  So where I finished the lecture before is where I start the next day, I haven’t got a set content.  If a student asks me an interesting question and I get the feeling that they want to know that answer I’ll go off for five or ten minutes or three or four minutes answering it, and if I don’t get to the end of where I thought I was going to get to, too bad I’ll do it next time.  So you go with the flow, you don’t go with a rigid thing ‘I’ve got to get through these 15 slides today and if I don’t the world will end,’ because it won’t.

I want them to get the big picture about what analytical chemistry is about in terms of solving an analytical chemistry problem.  They need to know the big picture rather than just focussing on the measurement step.

I remember when I was taught this, that the only definition we were given was Le Chatelier’s actual definition, or his principle, and I remember reading that language and going geez, that’s really hard to follow as a student, so I used to always try and present that and then break it down in to a more simple sort of version that I thought would be easier to understand.
