So, it’s helping to bed down analysis, problem solving, doing the sort of detective work to get to an answer. And the students also seem to quite enjoy having material presented to them in that way - here’s a spectrum, what do you think the structure is, because it’s a more active form of learning as well. So I find I enjoy teaching it, and they respond well in terms of, they keep coming in and asking me for additional problems to practise on which is clearly evidence that they feel it’s challenging them.

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. |
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. |
Try to show students that the fundamental form of matter is energy. Then that this can be represented as particles with mass or as waves (wave functions). Then try to show them that we use the model particle/wave that best helps us understand different phenomena. In class I often do this by asking questions about wave mechanics in particle terms. eg. If a 2s orbital has a node how can the electron pass accross it? Then explain to them the limitations and advantages of each approach. |
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. |
[Analytical chemistry] is probably one of the things that’s easiest to tie back to their own experiences. Because it’s very easy to link the idea of the importance of chemical measurement, is actually pretty easy to get across. You just talk about what is sports drug testing, road side testing, when was the last time you went to the doctor to get a path test. These are all forms of analytical chemistry. So I have a significant advantage over some people [teaching other topics] in being able to imbed it in their experiences. Everybody has some kind of experience we can draw on to say, yeah that’s analytical chemistry. The difficulty is of course to ensure that misconceptions don’t creep in. |
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 influence has been to stand back and let the students do the learning, rather than for the teacher to be barnstorming them with teaching. |
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. |
Students see equations and panic. Students struggle to transfer mathematical knowledge to chemical situations. Students silo knowledge and find it hard to relate concepts to actual systems. |
