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.

In the workshops, the workshop idea as we run them is that you are out and about and amongst the students all the time in those groups, seeing what’s going on in the groups, seeing how they’re answering their questions. They have set questions on sheets that they work through in groups and the groups of three just get one set. They’re all working on them together and you’re moving in and out and around among the groups and seeing how they’re going. In that circumstance you can quickly, having looked at three or four of your eight different groups, figure out where a particular issue would be and then that can be addressed on the board, it can be addressed with models or something like that. |
I know it's hard for them to 'suspend reality' and just accept a concept. They grasp for real life examples or metaphors which make sense to them. Students don't like the concept of something that can shift/change. They like one answer which is set and that's it, right or wrong - not 'shifts to the left/right'. |
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. |
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. |
The culture in the chemistry department was always lots and lots of content. And that’s changed now because you don’t need it, because they can find it another way, but you’ve got to give them the framework to understand the content. |
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 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. |
I find that some students pick up what the mole concept is from the idea of grouping numbers of things that are every day size. |
It now does come down to the quality of the presentation in terms of what you put on the PowerPoint I suppose, cos we all use PowerPoint. But I try most lectures to switch that off and use the visualiser and write things down by hand, where I can see that something is missing on the PowerPoint, or if I think the students haven’t got a particular message, don’t understand a reaction, don’t know about a mechanism. I’m happy to stop, go to the visualiser and write it down at the correct sort of pace, by which they can actually write it down themselves. |
