College lecturers, please help me land a dream job!

[MaudLebowski]

I've got an interview for a lecturing position, it's part time, doing hnc, hnd and foundation degree level.
I have a secondary pgce obtained many years ago, loads of academic qualifications and industry experience, but I'm fretting about the microteach I have to do at interview.
20 minutes at that level is causing me problems, as I'll have to rush if I'm assuming little prior knowledge to get to the bit they're interested in. If I assume prior knowledge they might get totally lost and I'll look like a fool!
My dH is a secondary teacher, he says I should do something basic and get the students to do an activity rather than lecture as such, but that feels too school to me, surely college is more lecture-y, I know uni was very much 'lecturer goes on for an hour- students listen'. Dh says too much talking is frowned on by ofsted.
What would you do? Is college like school or like uni?
Any idea what the microteach is looking for, apart from me not to throw myself out of the window in a panic, which currently feels increasingly likely?
Any advice at all greatfully received!

I agree you need to have student involvement. An absolute mistake to stand up at lecture for 20 minutes. IMHO.

Gosh, great ideas above. Incase it helps spark you own ideas

Could you present a few lines of code and get the students to tell you what it would do? Keep to a simple example,

Important things will be (as someone above has already covered better than i can describe) how you introduce the topic, set up the activity, get feedback and ensure that the key learning points are covered explicitly and implicitly.

Take your time and make sure you come over as engaging and organised, rather than flustered. All the best. xx

I've been in a few teaching panels for academic jobs, where candidates have 20 mins on the lines you describe.
I would say, don't start by bemoaning, or repeat, the fact that 20 minutes isn't very long. Some people do this and it's a waste of time and it just seems a bit churlish and like a refusal to engage with the task.
Definitely don't lecture.
Try to think about what you want them to leave having learnt or thought about that they didn't know before.
Be really well planned and organised - students even more than staff don't like it when the time is badly planned, or someone tries to go over.
Use PowerPoint sparingly, if you do. And make sure it's relevant.
Ask them for questions at the end - and if they have any, answer as positively and relevantly as you can - don't use the question as a way to lecture about something else.

Hi there
WE've moved this to the staffroom to find some more folk to help

Thank you all so much for your input, it's really good to see that wherever you're teaching you all expect the same sort of thing in these circumstances. If everyone had said something different it would be a lot harder to gauge! I still need to think through the activity so it's neither too difficult or too easy but you've all really helped me :)
