Strategy

When they come in I give a very simple quiz which we do using clickers, the sort of anonymous audience response systems, and I just test a few multiple choice questions, just testing their understanding of some of those terms and then when I notice that there’s, well, anything more than 10 or 15% of students who don’t correctly understand those terms then we go through a process of exploring what those terms are and why they apply to what they apply to and then I retest that a couple of weeks later.... I notice at the end of the year some of the students can lapse back into their old habits, so it’s something that I am going to need to think of continuing to reinforce.	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.
The actual curly arrow mechanisms are in a way themselves cartoons, how they map to the reality in the way that a Micky Mouse might map to real life.	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’.
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.	So my approach to teaching is that I want students to be actively engaged with the material throughout the lectures, all the tutorials, all the workshops or whatever, and so I’m not giving didactic lectures, I’m not using lots of PowerPoint slides. I’m giving them information. I’m describing things to them, but then I give them lots of examples and lots of things to do, lots of activities to do.
Many years ago, lecturers only had one style, you know they just wrote on the blackboard, actual blackboard with chalk. That was the only style. They just talked... That’s all I knew so that was fine and so I thought, well I’ll just continue that and the students weren’t understanding what I was saying and explaining and I thought, oh hang on what’s going on here? This is the way I was taught. Come on, it should work. So, yeah I think it would be good if someone told me that at the start, but as I said because I’d end up doing my Diploma of Education that opened my eyes to that and that’s when I started to utilise different strategies and I appreciate that not everyone is going to understand one way of, my teaching way.	Students from high school might understand that vinegar for example is a weak acid compared to hydrochloric acid, but they never knew why. And you could then show them that with equilibrium, this is why. And all of a sudden they’re, 'oh, I’ve always known that I shouldn’t spill HCL on my hand, but I can spill vinegar on my hand and put it on my fish and chips'... Those sorts of moments can really... the students go ‘oh wow.’ Anonymous
You're learning a new language as well as new concepts. There's lots of vocab, so terms like electrophile and nucleophile and many others. So learning the language, learning the code that we use, the curly arrow code, and then starting to apply that in half a dozen or a dozen or so different contexts, different reactions.	We all spend a certain amount of our class time going through definitions and jargon and getting students up to speed with the basic area and now that’s material which I take out of the class and put online and let students read and understand that in their own time before they come to the class.
