They [students] expect to either succeed or fail immediately or very quickly on particular problems. They do not see the process as a learning process.

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. |
We do an awful lot of focus on teaching but realisticly, authentic assessment that actually engages the student, that’s a tougher ask... I set a lot of essay type assignments. I think we ought to do more of that in science. But when I started doing this I used to get very poor results and it’s taken me a little while to realise that the students weren’t understanding what the questions was. They didn’t understand what I meant by compare and contrast or discuss or argue for this. So increasingly now I use workshops to actually spend time with the students unpacking, what is this essay assignment about? What am I actually asking you to do? What do you need to think about? And not assuming that they know how to write an essay. |
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. |
[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. |
It’s something that needs to be reinforced, it’s not that you taught it in this unit for three weeks, we are over it. It’s something that keeps coming back, and that you can possibly reintroduce it, with not much change to your teaching. Not every single time, but every now and then remind the students, ‘remember, you still have to think about stoichiometry and limiting reagents’. |
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. |
So into the lectures I put kind of ad breaks, I suppose, short 'meet the scientist' breaks. So we would have a photograph and fun facts about a scientist and various places we would have a stop, and I have told them that all of that information wasn't on the exam, so they knew that they could stop and just take a breather and then pick back up on the chemistry afterwards. So that, I think helped, especially the ones that were just finding it all a bit kind of overwhelming. |
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. |
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. |
