I think it’s a key teaching topic, also because it’s teaching students to look at data and to interpret data, to assess which part of that data is going to get them to the answer and which part is exquisite detail that they can come back to later on. 

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.

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.

I think it’s really important that people mark assessments.  Mark, and see what the students actually end up knowing.  Because they can pretend to themselves that students have understood everything, but if they actually have to mark the exam papers, or the quizzes, or whatever it is, they actually are confronted with the students actual knowledge.  I think that’s really influential.  The second semester of teaching, when you think you’ve explained things well, and then 90% of the class have not got it, then it’s not the students fault at that point, it’s probably your fault.  So I think that assessment is really important.  Not only for the students, but also for the marker.  I think you can learn a lot from marking.

It’s something that needs to be reinforced, it’s not that you taught it in this unit for three weeks, we are over it. It’s something that keeps coming back, and that you can possibly reintroduce it, with not much change to your teaching. Not every single time, but every now and then remind the students, ‘remember, you still have to think about stoichiometry and limiting reagents’.

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 to get the students to straight away mark for somebody else what they’ve just done and then to mark or take part in the marking of two other versions of the same thing is really powerful.  So it’s not so much me directly finding out what they do and don’t understand but using methods by which they can diagnose for themselves.  I haven’t got this, she has, or yep I have got most of that, she hasn’t, and I can see where she went wrong.  Very powerful, very powerful indeed. 

I changed my method of teaching to be a team-based learning approach where in fact as teams they are responsible to each other within the team for their level of engagement or for what they put into that team and if they don’t put in what the team thinks is useful then they get marked on that, their peers mark them on how much they’re contributing to the team’s goals.  So rather than me as the educator saying you need to do this and you need to do that, in fact the system is such that as a team they’re responsible for a certain outcome and the team must achieve that outcome and so they need to work together.  For the students who don’t put in as much as the team expects of them then there is peer pressure to increase their level of input and their engagement and if the students don’t then the team members get a chance to reflect upon that and give them a sort of team work score.

We all spend a certain amount of our class time going through definitions and jargon and getting students up to speed with the basic area and now that’s material which I take out of the class and put online and let students read and understand that in their own time before they come to the class.
