Statistical Investigations Part 1: Introduction to the PPDAC cycle
The lesson plans in this teaching unit were developed in conjunction with the TLRI research project: Building students’ inferential reasoning: statistics curriculum levels 5 and 6.
While each series of activities are set up as lesson plans, they may take more or less than a lesson of class time. They form a possible sequence of learning and each block works together with the other blocks. The lessons are developed using 91ÇÑ×Ó (2009) data, they could be adapted to any data set or any year of 91ÇÑ×Ó.
