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 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.

Chemistry is a different language so I try to approach it that way by explaining the ideas behind symbols.

At the start of every class my standard thing was ‘can you see me, can you hear me, can you see the slide?’ I would always look up the back for someone to put their hand up and always I would never talk to the front row. I’d always talk middle and back row and if someone was talking in the back row I’d pick them up and say ‘hey you, be quiet’ and then they know that I’ve seen them.

So you’ve got to focus on the whole class not just the people at the front - the people at the back as well.  Because sometimes smart people sit at the back as well, not just the dummies who want to get out. You’ve got to make sure you know everyone in the class.  And the surprising thing is that most kids sit in the same place every lecture.

So you can actually recognise where they are and who they are.  You don’t know their names but there’s a pattern in the way they sit.  You’ve just got to be aware of that.  So the trick is to embrace the whole class with your - you know physically, just with your eyes and and the way you talk.  You know, when you wave your hands, wave it to the back row. Make sure they’re involved.

It is vitally important for their understanding of chemistry that they understand that molecules are three-dimensional things and that they have a spatial requirement in that they have a shape of their own and that shape will change.  They can't do higher level manipulations without an understanding of three-dimensional nature of molecules.

The influence has been to stand back and let the students do the learning, rather than for the teacher to be barnstorming them with teaching.

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.

And it’s so essential, if you are in the middle of a discipline, to have a really well developed sense of what your colleagues around you are teaching, so that you can make connections.

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.

Too often I think students and others think that analytical chemistry is just that measurement step.  When you use the AA, when you use the ... and doesn’t take into account, well all of the other stuff, what’s the actual problem you’re trying to solve?  What are you actually trying to do, sampling, measurement, validating your results? Because only then when you’ve got a result, only then does it actually become information.
