I’ve just finished my planning for the introduction to Bootstrapping confidence intervals. Just google docs and slides sorry, nothing as flash as what Liam put together with our L2 Inference site. Feel free to use as you like.

I haven’t done teacher notes for each of the activities, but I have uploaded our Sequence of Learning experiences –> although it doesn’t match this set of lessons exactly, it does hopefully give enough details for you to follow the gist of things.

I’ve included my awful videos – very cringee, and quickly done – does anyone else manage to watch their own videos without feeling really silly? NOTE: a little of the things in here will be specific to our context at Cashmere – just ignore/adapt as needed. NOTE-NOTE: some of our Year 13s haven’t seen any multivariate data analysis since they were Year 10s, hence the need to go back and develop WHY we need confidence intervals.

Here’s my planning document, and hopefully all the links from there take you to the right place :). The folder with everything is here (for self-service to resolve link-issues… there’s lots of links!)

Let me know if there are any issues….

Topic | Teaching Resources |

1 Introduction to the topic→ sample to population inferences → plan for online world | → Powerpoint to work through live → PDF version to share with students → Video talking through ppt if students miss live lesson |

2 A brief overview of sampling → Why sample → Features of a good sample | Short Powerpoint →PDF version to share with students →Video explanation of sampling methods (less than 5 mins, linked in ppt) |

3 Repeated sampling to motivate the need for a confidence interval→ Doozers used to answer “ What is the mean height of Doozers in Fraggle Rock?”→ Sampling error & sampling variation → Leading to the need for an interval for population mean | → Powerpoint to work through live → Doc to assign to students → Sheet to collect repeated sample means→ PDF version to share with students → Video (part 1, part 2) to share with students who miss live lesson |

4 Introduction to bootstrapping for confidence interval → new analysis tool → NOTE: this is a BIG lesson (as you can tell from the 5 part video!) | → Dizzy Doozer Spinner → Anna’s magic sampler→ Powerpoint to work through live → Sheet to assign to students → Sheet to collect re-sample means→ PDF version to share with students → Video (part 1, part 2, part 3, part 4, part 5) to share with students who miss live lesson |

5 Comparison situations→ Confidence interval interpretation → Making the call → Impact on question format → NOTE: this is a BIG lesson (as you can tell from the 5 part video!) | → Powerpoint (part 1, part 2, part 3, part 4) to work through live → PDF version (part 1, part 2, part 3, part 4) to share with students → My call is … student task (assign to students) → Video (part 1, part 2, part 3, part 4, part 5) to share with students who miss live lesson |

6 Putting it all together→ Investigative question + hypothesis → Analysis graphs & stats (no comments) → Bootstrap distribution → Confidence interval interpretation → Making the call | Yet to be constructed! I’ll update when I have this together… |
