Students should [only] be limited by students' curiosity.

The big picture is that in any topic there’re key principles, and if you as a lecturer can get across the key principles, that then sets them up to solve problems and to think about the other principles and how they connect.  But if they don’t, if they’re not prepared to accept the fact that there are these key principles you need to understand then it’s not going to work.

Students see equations and panic. Students struggle to transfer mathematical knowledge to chemical situations. Students silo knowledge and find it hard to relate concepts to actual systems.

So the strategy is to reflect, to change things, to be flexible, to talk to them but not talk down to them, and certainly I would say to any young lecturer don’t be writing the lecture the night before. Know what your course is because then you can jump back and forth as you talk about something.  You can say yeah we talked about this a week ago or something like that, you know. Know what you’re going to talk about, the whole thing, because then you can put it all together as a package.

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.

So the first thing that I really stress that people do, is that they actually go and watch some classes.  I think that’s the most important thing.  When they’re coming straight out of a post doc, or they’re coming straight out of the Research Centre, and then, they’re told they’re going to be lecturing 300 first year students, they’ve got to go and sit in the back of the lecture theatres for a few weeks.... when I came over from the UK to here, and the class sizes are about three or four times as big, it was just a real help to be able to see what worked and didn’t work  – how little time the students were on task in quite a few lectures.  Where the lecturer would just be talking and be oblivious to this.  I think people just learn a lot by seeing good things, but they also learn a lot by seeing quite bad things going on.

It always seems like we're starting from further behind than a lot of the other sciences are because they seem to know less about chemistry when they get here.  If I say ‘think of a famous physicist’ you probably already have thought of three.  Then you could go outside and ask someone to think of a famous physicist and they'd probably think of at least one of the same ones.  You do the same thing with biologists.  If I say to think of a famous chemist … that's within chemistry circles, we can't do it.  We can name one but you know if you go out there and say, ‘Who is this person?’ they've got no idea.  So for some reason … we've never … chemists have never been able to popularise our topic, our content.  We've never been able to make it exciting enough that someone who is not studying it still wants to know about it.  And so I do think we've got a bigger challenge, for whatever reason.  Maybe there's something about chemistry that makes it less enjoyable, I don’t know.  There's definitely been an ongoing issue for us that it's not … people just don't know anything about it... Most people know Einstein's theory of relativity.  You don't see that really in everyday, go, "There's the theory of relativity at work." Newton's Law, sure, you see those and you … but, yeah, everybody knows Einstein.  And a lot of … I'll call them lay people, I don't like the term, but non-science people, could probably give you a hand wave explanation of what the theory of relativity is about, which is a pretty abstract thing.  I mean, if we think of the equivalent types of things in chemistry that are that abstract, nobody has a clue.  We teach them in third year to the remaining hard core people that are left. 

It was a revelation to me in second year when [one of the top professors] said to me, "Buy a model kit." And so now I tell all my students.

In the workshops, the workshop idea as we run them is that you are out and about and amongst the students all the time in those groups, seeing what’s going on in the groups, seeing how they’re answering their questions.  They have set questions on sheets that they work through in groups and the groups of three just get one set.  They’re all working on them together and you’re moving in and out and around among the groups and seeing how they’re going.  In that circumstance you can quickly, having looked at three or four of your eight different groups, figure out where a particular issue would be and then that can be addressed on the board, it can be addressed with models or something like that.

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