The difference between chemistry as it happens in a flask, chemistry as we show it on paper or in a textbook and helping students to understand that these are representations and they're conceptual frameworks that we use to understand our discipline and so helping them put those two pieces together.

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. |

The big picture is that in any topic there’re key principles, and if you as a lecturer can get across the key principles, that then sets them up to solve problems and to think about the other principles and how they connect. But if they don’t, if they’re not prepared to accept the fact that there are these key principles you need to understand then it’s not going to work. |
Students should [only] be limited by students' curiosity. |

They struggle with the language of chemistry. So we sort of need to teach them the process and how to work out how to do these things. We know that their tendency is just to attempt to memorise reactions. Whereas if we can teach them to derive … find out what the nucleophile and the electrophile is then all they have to do is draw a curly arrow from the nucleophile to the electrophile, rather than trying to work out what the reaction is itself. |
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. |

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. |
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 think for a lot of people, before they started chemistry, especially if they haven't done any chemistry before, they've got no real understanding of the difference between macroscopic things and microscopic and atomic sized things. We all know how important that distinction is. |
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. |
