Inquiry and Communication in Maths and Stats:

1. Inquiry and Communication in Maths and Stats: Training students to be self-starters who persevere and communicate their thinking. Presented by Jeremy Brocklehurst

2. Goals of workshop today: • “Open-ended holistic task” : - What are they exactly? - What makes them good vs a waste of time? - Why ?? - Does this lead to bigger questions about what Mathematics is ? - How to help all students with them. Warning: I have some ideas but more questions than answers! This is where you come in!

3. Success criteria for this workshop!

4. Those open-ended problems everyone just loves !! .

5. How many coins could we fit on the floor of this classroom?

6. How many coins could we fit on the floor of this classroom? How could we get the greatest possible money value using a single layer of coins?

7. What’s the minimum length of fencing needed to enclose a paddock holding 50 cows if each cow requires 25m2 to graze?

8. The quadrilateral ABCD has vertices A (0, 0), B (1, 4), C (5, 3), and D (7, 1). P, Q, R, and S are the midpoints of the sides of the quadrilateral. If the points P, Q, R, and S are joined, a new quadrilateral is formed. What type of quadrilateral is PQRS? You must show the co-ordinate geometry methods you used to get your answer.

9. The following graphs are distributions of ages in two populations. The United States of America (based on US census data) and Facebook users: Describe features of the distributions comparatively. Aim to make at least three statements. Support your statements with statistical evidence.

11. Questions to discuss: • Whygive students open-ended ‘holistic’ tasks? Is there any research around this or is it just a “fad”?

12. Questions to discuss: • What do students find most challenging about open-ended Maths or Stats tasks?

13. Questions to discuss: • What is required for a person to become engaged and engrossed in them?

14. Questions to discuss: • What about students who insist on being “spoon fed” ?

15. Questions to discuss: • Other issues?

16. Writing rubrics can be useful

17. What the OSEM writing frame means: O stands for Obvious observations Write down one thing you notice, then leave a gap, and write down something else you notice. Try to get 3 obvious things. S is for Specific Under each obvious observation, explain what you mean so that another person would get it. E is for Evidence Support each observation with numbers or calculations. M is for Meaning: So what? Write down what each of your points tells you about the original problem/situation. What else could we find out?

26. Examples of student work…

27. Observe (look for obvious) %

28. Specific with Evidence (numbers) %

29. % Meaning:

30. % Meaning: So what?

31. % Meaning: So what? What does this tell us about the situation?

32. In the Level 1 Multivariate Data standard (1.10), my students found OSEM a useful guide when writing their conclusions:

33. 1.10 Multivariate – Conclusion Obvious

34. 1.10 Multivariate – Conclusion Obvious (Make call: Yes/No)

35. 1.10 Multivariate – Conclusion Obvious Specific

36. 1.10 Multivariate – Conclusion Obvious Specific (about what? – popns / variable)

37. 1.10 Multivariate – Conclusion Obvious Specific Evidence

38. 1.10 Multivariate – Conclusion Obvious Specific Evidence (justify, support with stats) Meaning

39. 1.10 Multivariate – Conclusion Obvious Specific Evidence (justify, support with stats) • Meaning (so what?) • Context (does it make sense etc.? • Sampling variability

40. 1.10 Multivariate – Conclusion Obvious Specific Evidence Meaning

41. 1.10 Multivariate – Conclusion Obvious (Make call: Yes/No) Specific (about what? – popns / variable) Evidence (justify, support with stats) • Meaning (so what?) • Context (does it make sense etc.?) • Sampling variability

42. 1.10 Multivariate – Conclusion

43. 1.10 Multivariate – Conclusion

45. And even in Level 2 Coordinate Geometry

46. And even in Level 2 Coordinate Geometry Obvious observations Specific (labelling) Evidence (calculations) Meaning (so what?) (Relate back to problem)

47. 2013 Level 2 Probability external Compare and contrast the two distributions. You should discuss shape, centre and spread in relation to the context.

49. Algebra in Years 9 and 10 Key ideas in teaching it: Start with meaningful problems that involve either: • The students themselves and can be acted out. • Something that might interest them (saving money for something, get to know common interests of class members). Students creating their own problems is a powerful tool to engage and motivate learning.
