Hourly paid lecturing

[WillowB]

I've seen a post advertised for an hourly paid lecturer (primary teaching)
I haven't lectured before but I'm interested in the role . The hourly rate is £35 to include other duties such as marking etc which I guess when you factor in the extra time spent on those activities doesn't make it particularly lucrative even compared with supply teaching.
I just wondered if anyone with experience could outline a few of the pros and cons? Is it likely to be fairly flexible in terms of not being 9-5 every day?
Thanks

It is on the PGCE course, or a school-based route with you providing the academic input from your university?

The uni offer BEd, PGCE and Teach First.
The ad just states to teach on their undergrad courses and mentions spending time visiting students in placement schools so possibly across all three.

They are quite different route with possibly quite different ways of teaching.

I have worked sessionally in a similar way - I was on two rates of pay: one for observations and teaching, and one separate, much lower, for marking. This was twice-yearly assignments. And I was allocated 90 mins of marking pay for each assignment when they always took longer.

Thank you. This is a fixed rate which I think is intended to cover everything. I was slightly concerned that if it takes a lot of prep and marking then I could end up working for about £4 an hour
I haven't lectured before so have no idea of how long it takes to prepare etc. I think I'll drop them an email later to ask for a bit more info.
