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.

They [students] reveal great misunderstandings about the molecular world. So the difficulties and limitations are as a result of not spending sufficient time on getting them to think about this world, and spending too much time on doing. You know, we’ve got to spend some time, but you can’t spend too much time, I think, on a lot of the ideas that we do teach, and doing calculations and things that, really, no one else does. It’s really something that’s done almost like it’s make-work-type stuff.

I started lecturing before I did my Diploma of Education and I would have recommended to all of the lecturers to do it because it really helped me in my teaching.  Mind you, I already had a bit of experience, I don’t know, you know, the chicken or the egg type thing.

We do an awful lot of focus on teaching but realisticly, authentic assessment that actually engages the student, that’s a tougher ask... I set a lot of essay type assignments. I think we ought to do more of that in science.  But when I started doing this I used to get very poor results and it’s taken me a little while to realise that the students weren’t understanding what the questions was.  They didn’t understand what I meant by compare and contrast or discuss or argue for this.  So increasingly now I use workshops to actually spend time with the students unpacking, what is this essay assignment about?  What am I actually asking you to do?  What do you need to think about? And not assuming that they know how to write an essay.

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.

This understanding builds students' knowledge about the basic structure of matter which stimulates them to think in sub-microscopic level that provides the fundamental understanding for further chemistry learning.

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.

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.

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. 

I was thinking about Le Chatelier’s principle and how that’s quite cumbersome in its wording, and so when I teach it, and how I always break that down into language that’s probably easier for students to understand, and Bob tells me that’s called repackaging, and I sort of thought that through all my teaching I do a fair bit of repackaging, a lot of the time, so I guess that was just a trait that I use and has been pretty successful for me, I think.
