CENTRE FOR EDUCATIONAL DEVELOPMENT
New Directions in teaching Statistics
Workshop 2
Barb Costelloe and Anne Lawrence NPGHS Adviser in Secondary
Numeracy & Mathematics
• 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:
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.
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).
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.
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
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
• Progress with iNZight and GenStat• Excel simulations• Other software (Efofex, fathom)
Using software in teaching Probability
