This is a simple knowledge type question
Brains ….Men's brains have 10% more volume and 4% more cells, but women's brains contain more nerve cells and synaptic connections.
Women have larger limbic cortexes than men, but men have larger parietal cortexes.
Men have 6.5 times more gray matter in their brains than women, but women have 10 times more white matter in their brains than men do.
Men and women's brains age differently; men suffer more overall loss in brain volume and lose mass specifically in the frontal and temporal lobes, while women lose volume in the hippocampi and parietal lobes.
Some detail to follow up our initial assessment of students knowledge – we can come back to this later on

Can we influence response from others behaviour – in this case the majority view (its wrong!). Get another chance to vote after thinking about it – we can then compare 2 tries

More often …
• People just use recall slides• These are useful– Informative for the instructor– Emphasis for revision • If you pick an important take home message
– Allow student to gauge performance
• Easy to make and a good way in • but quite dull if over used

Set up the ConcepTest (it’s a well known name)And get 1st response. Sometimes we don’t show this result (a with the maths question)

Some thoughts on disappointment…from Writing Great Clicker Questions [S.Chasteen]
• 1. Fail to explain why you are using clickers.
• 2. Use them primarily for attendance.
• 3. Don’t have students talk with each other.
• 4. Use only factual recall questions.
• 5. Don’t make use of the student response information.
• 6. Fail to discuss what learning means or the depth of participation and learning you
expect in your class.
• 7. Think of clickers as a testing device, rather than a device to inform learning.
From the papers – see IT Extras module in the VLE.
I thik these reasons for failure are more informative than the reasons for success
