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.

This understanding builds students' knowledge about the basic structure of matter which stimulates them to think in sub-microscopic level that provides the fundamental understanding for further chemistry learning.

We teach way too much stuff.  We teach way too much stuff that we used to teach because students didn’t have the resources available to them that they’ve got now.  I mean if you look at the resources - they’ve got textbooks, they’ve got electronic media, they’ve got Sapling. They can do the problems in their own time in a guided way with something like Sapling. We don’t have to do it, all we’ve got to do is give them the framework to solve the problems.  And I think we often misunderstand how much we should give them because I think we underestimate the value of letting them solve problems in a guided way with things like Sapling.  And I think, you know, in the old days we’d just do problem after problem after problem, which is as boring as anything.

At the start of every class my standard thing was ‘can you see me, can you hear me, can you see the slide?’ I would always look up the back for someone to put their hand up and always I would never talk to the front row. I’d always talk middle and back row and if someone was talking in the back row I’d pick them up and say ‘hey you, be quiet’ and then they know that I’ve seen them.

So you’ve got to focus on the whole class not just the people at the front - the people at the back as well.  Because sometimes smart people sit at the back as well, not just the dummies who want to get out. You’ve got to make sure you know everyone in the class.  And the surprising thing is that most kids sit in the same place every lecture.

So you can actually recognise where they are and who they are.  You don’t know their names but there’s a pattern in the way they sit.  You’ve just got to be aware of that.  So the trick is to embrace the whole class with your - you know physically, just with your eyes and and the way you talk.  You know, when you wave your hands, wave it to the back row. Make sure they’re involved.

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.

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 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.

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.

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.

Chemistry is a different language so I try to approach it that way by explaining the ideas behind symbols.
