I have one slide where I'm first demonstrating how we use curly arrows and that shows an arrow going in a particular direction from a nucleophile to an electrophile and emphasising that the arrow shows electrons moving - so it's got to start from where they are. There has to be some electrons there for them to move. So the whole screen goes black and comes up with a little orange box of 'never do this' which is an arrow starting from an H+, which has no electrons. The dramatic emphasis that the whole room goes dark and then it's just up there.

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. |
The concept of a continuum is, I think, really important in chemistry and… what I see is that students come up with this issue of things being black or white. They struggle with this concept of the in between stuff. |
Chemistry is a different language so I try to approach it that way by explaining the ideas behind symbols. |
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. |
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. |
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 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 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. |
