2. Who has bigger brains? • Men • Women • No difference This is a simple knowledge type question

3. 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

4. Is increased brain size linked to increased cognitive ability? • Of course • Don’t be daft • Yellow This is a simple knowledge type question But acting as a follow on, implications Of new knowledge we have just given

5. Father Ted

6. Father Ted was explaining • Perspective • Size constancy • Depth of Field • Cortical Scaling This is a simple knowledge type question But from observation not memory

7. What sort of pie do you like ? How easy is t to make a question in TP

8. What sort of pie • Meat • Apple • Pork • Veg

9. Facebook maths ? • 28 • 26 • 30 • 0 There are sixteen 2s in the list This is a procedural knowledge type question , with hidden results below, we don’t always wan to show reults

10. Want to change your mind ? • 28 • 26 • 30 • 0 There are sixteen 2s in the list 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

12. BOMDAS • Or BIDMAS or …. • When do we do each bit of the calculation… Provide some teach – at this point with time I would have gone through in detail BOMDAS There are sixteen 2s in the list

13. Want to change your mind ? • 28 • 26 • 30 • 0

15. 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

16. Women’s brains have… • 6.5% more volume • Larger parietal cortexes • 10% more grey matter • 10% more white matter • All of the above A recall from before – 42% gt it right 58 wrong ! Many people don’t remember facts for long during the lecture

17. More Complex .. ConcepTestAn example the Monty Hall Puzzle aka Goats & Ferrari • Yes • No 15% 85%

18. Monty Halllet’s agree on a door to choose….. • Green • Yellow • Orange

19. I open the _____ doorDo you want to • Switch • Stick • Doesn’t matter 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)

20. I open the _____ doorDo you want to • Switch • Stick • Doesn’t matter At bthis point we would have student-student Debate/chat/interaction pairing up people who disagree And revoting to get Peer Instruction (google it!)

21. sun

22. If the sun is 100 sun diameters from Earth how many moon diameters is the moon from the Earth ? sun moon ? md md earth sd 100 sd Quite a complex question, requires knowledge, thought, Understanding, interpretation etc very Bloom!

23. If the sun is 100 sun diameters from Earth how many moon diameters is the moon • 10 • 100 • 1 • 1000 • Not possible to tell It’s 2 – think eclipse

24. 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 informlearning. From the papers – see IT Extras module in the VLE. I thik these reasons for failure are more informative than the reasons for success 
