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.

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.

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.

I want them to get the big picture about what analytical chemistry is about in terms of solving an analytical chemistry problem.  They need to know the big picture rather than just focussing on the measurement step.

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. 

I don’t like to be in a position where I’m stood at the front talking for 50 minutes. I like to be a in a position where I’m engaging with students, where they’re engaging with each other, where there’s a buzz, where there’s things happening, and it’s an active environment.

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.

Ions and ionic chemistry are essential to life and just about everything they will run across.

So, just to make them do some work, and made them think about the ideas themselves.  Talk amongst themselves about it.  I think that just too much of me in the lecture just washes over them after five to 10 minutes.  So they just need to have a break, think about the problem, do a couple of problems, talk amongst themselves... that seems to help, with both the variety of students in the class, but also just keeping them engaged.  Keeping their attention.

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.
