You're learning a new language as well as new concepts. There's lots of vocab, so terms like electrophile and nucleophile and many others. So learning the language, learning the code that we use, the curly arrow code, and then starting to apply that in half a dozen or a dozen or so different contexts, different reactions.

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.

Difficulties are having to relearn something that they thought was true from school and not understanding the evolving nature of science. New knowledge is easier to assimilate than changing old knowledge.

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

It’s continuous learning.  I mean, what I used to try to say to students when I taught the acid-base stuff I’d say ‘look there are only about six types of problems and if you can solve one of them you can solve them all because they’re all the same.’ But what you’ve got to be able to do is look at the question and say to yourself ‘this is one of those types of questions therefore this is the way I should think about approaching it.’  So take the question, dissect it, decide what you’re being asked to do, decide what information you’re given, and then say ‘yeah that’s one of those types of questions, this is the way I should go about solving it.'  If you can get that across to them, that it’s not a new universe every time you get a question, it’s simply a repeat universe of the same type of question... But many students tend to look at each problem as a new universe and start from the beginning again.  Many students don’t see that there is a limited number of problems that can be asked on a certain topic.

So I think we just, I used to give them, perhaps, 10 minutes to work on a problem, now I probably only give them two or three minutes.  I find that concentrates them and prevents them just talking about the State of Origin or whatever it is that’s on their mind.  We just need to keep changing the activity, rather than have extended activities... we want them to chat, but I think human beings won’t sit and chat about quantum mechanics for more than two or three minutes, they’ll get onto what they want for lunch.  So it’s that balance.

I don’t like to be in a position where I’m stood at the front talking for 50 minutes. I like to be a in a position where I’m engaging with students, where they’re engaging with each other, where there’s a buzz, where there’s things happening, and it’s an active environment.

So, it’s helping to bed down analysis, problem solving, doing the sort of detective work to get to an answer.  And the students also seem to quite enjoy having material presented to them in that way - here’s a spectrum, what do you think the structure is, because it’s a more active form of learning as well.  So I find I enjoy teaching it, and they respond well in terms of, they keep coming in and asking me for additional problems to practise on which is clearly evidence that they feel it’s challenging them.

The difference between chemistry as it happens in a flask, chemistry as we show it on paper or in a textbook and helping students to understand that these are representations and they're conceptual frameworks that we use to understand our discipline and so helping them put those two pieces together.

[Analytical chemistry] is probably one of the things that’s easiest to tie back to their own experiences.  Because it’s very easy to link the idea of the importance of chemical measurement, is actually pretty easy to get across. You just talk about what is sports drug testing, road side testing, when was the last time you went to the doctor to get a path test.  These are all forms of analytical chemistry.  So I have a significant advantage over some people [teaching other topics] in being able to imbed it in their experiences.  Everybody has some kind of experience we can draw on to say, yeah that’s analytical chemistry.  The difficulty is of course to ensure that misconceptions don’t creep in.
