1. CENTRE FOR EDUCATIONAL DEVELOPMENT New Directions in teaching Statistics Workshop 2 Barb Costelloe and Anne Lawrence NPGHS Adviser in Secondary Numeracy & Mathematics

2. To clarify the curriculum changes for the statistics strand with particular focus on statistical literacy, statistical inference, and statistical investigations ; To explore the implications of these changes for teaching and learning programmes at years 10 to 12. Objectives:

3. Datacards? Stat literacy articles? Talks on census at school? Review of “homework”

4. Reflection: What are the key changes in Probability?

5. What are the key changes in Probability? (thanks to Louise Addison)

6. Key changes in Probability (session 1 booklet) Students will need to understand the underlying concepts of probability and not just use the rules. There is an emphasis on probability distributions, seeing the whole rather than just calculating the probability of a single event. Understanding the difference between theoretical and experimental probability distributions and the connections between them.

7. What’s new in Probability (session 1 booklet) At Level 5: Understanding the role of variation Theoretical and experimental probability distributions At Level 6: Appreciating the role of sample size, the connection between sample size and variation. Laying down foundations for the binomial distribution (discrete situations).

8. What’s new in Probability (session 1 booklet) At Level 7: This is where students should first meet probability trees as a calculation tool. Use of two-way tables to solve probability problems. Simulations remain an important focus. Presenting the normal distribution as a useful model for explaining and exploring many situations.

9. What about Probability in the new Achievement Standards? One familiar and expected item One new, unfamiliar concept/idea Any that raise questions? Achievement Standards 1.12 and 1.13

10. Smorgasbord of tasks: Questions: Which students is the task appropriate for? Would you use it? If so, when? What do students learn from it? Suitable Probability tasks

11. What will we expect at Merit? ….at Excellence? Trial tasks for AS 1.13

12. Progress with iNZight and GenStat Excel simulations Other software (Efofex, fathom) Using software in teaching Probability

13. Recent TED talks Activities already available on the web Any activities you have to share? Other useful resources….
