I think we’ve all sat in lectures and gone, that was dreadful, so we learned quite a lot from understanding how not to do it as well as how actually to do it.  And of course the key is preparation and organisation..... whenever I go into a class knowing that I am beautifully organised, that gives you that extra confidence to project and to present, and you come away with that feeling that you know that the class has gone well and you’ve got the information across to the students in the way that you wanted. 

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.

I think personally the quicker the students can see that holistic approach to chemistry the better... Because that’s when they start to realise how cool it is.

We teach way too much stuff.  We teach way too much stuff that we used to teach because students didn’t have the resources available to them that they’ve got now.  I mean if you look at the resources - they’ve got textbooks, they’ve got electronic media, they’ve got Sapling. They can do the problems in their own time in a guided way with something like Sapling. We don’t have to do it, all we’ve got to do is give them the framework to solve the problems.  And I think we often misunderstand how much we should give them because I think we underestimate the value of letting them solve problems in a guided way with things like Sapling.  And I think, you know, in the old days we’d just do problem after problem after problem, which is as boring as anything.

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.

In the lab it comes out in a variety of ways.  It comes out most commonly when the student gets to actually start doing their calculations and you ask them to relate that back to what they’ve actually physically measured.  And when they start doing those sorts of things you realise there’s a bit of a misplaced idea here or a misconception that you can deal with there.

I use a lot of eye contact. The people in the back row are not anonymous, you know.  Make sure you’re talking to them and make sure that you see them.

The culture in the chemistry department was always lots and lots of content.  And that’s changed now because you don’t need it, because they can find it another way, but you’ve got to give them the framework to understand the content.

And it’s taken me a long time to discover what sort of teacher I actually am.... I had a colleague who said to me, ‘oh you’re a narrative teacher’.  I said, ‘I’m a what’? ..... I tell stories, essentially.  I tell stories.  I turn everything into a story in some way... and again, analytical chemistry lends itself to that.  That you can link it to stories that are in the media, personal experiences, my own personal research experience.  The student’s own experience.  So it’s shared.  So while I thought I was a straight forward didactic teacher, you know I just stood there but I’m not, I asked students, ‘alright who’s got experience of this’, and then I use a narrative form to get that across, and it seems to work.

But if you’re honest, they’ll be honest right.  And I think that’s really important. If you b*gger something up and you really do make a blue or even a little blue, tell them.  Say ‘oh look this was wrong, you know this is what it should be’.  So that’s important - to be honest, to be upfront.  Recognise that we’re dealing, in 2015 or 2014, we’re dealing with OP1 to maybe 14. Recognise the breadth of that class. Don’t teach the top, don’t teach the bottom, teach somewhere in the middle, but try to make sure that you don’t lose the top ones and lose the bottom ones, which is very difficult to do and you only do it with experience.
