The Connections 2016 activity sequence

The following table includes a brief summary of the Connections 2016's activity sequence.

 Activity synopsis No. of 90 min. lessons The first cycle: Sampling methods (a population of 496 students) Activity 1: The real world: time to ask and time to sample (n=18) 4.5 Introduce to the main topic of the project (“Children make a change”) and the sub-topic of the first cycle (technology); participate in an EDA activity following the statistical investigative cycle; present investigations. Activity 2: The probabilistic world: The strings activity (n=10 out of 18 strings) 2.5 Explore bias and random sampling methods by drawing samples from a population and compare between the drawn samples; reason with SGDs. The second cycle: First random sample (a population of 1,300 students) Activity 3: The real world: Data collecting (n=60) 2 Introduce to the activity context (sports and gender) and the online questionnaire; plan the random sampling method (a raffle), and collect data (15 grade 2, 4 and 6 students from their school and 15 eighth graders from their future middle school). Activity 4: The real world: data analysis of the first sample (n=60) 2 Investigate a random sample (60 cases, 27 variables) using TinkerPlots; model conjectures about the population (hands-on); present investigations. Activity 5: The probabilistic world: Model the population and draw random samples (n=60) 3 Model a conjecture about the population (TinkerPlots); investigate random simulated data samples (60 cases, without replacement), invent methods to compare between samples; present investigations. Activity 6: The probabilistic world: What can we learn from 100 samples? (n=60) 1 Generate and reason with SGDs of 100 samples; present investigations. Activity 7: The probabilistic world: The minimal and trustworthy possible sample. 1 Search and choose the minimal and trustworthy sample that can be collected by the students; present investigations. The third cycle: Second random sample (a population of 1,300 students) Activity 8a: The real world: Collect and investigate the second sample (n=105) 2 Collect additional random sample (15 students of grades 2, 4 and 6); Investigate a random data sample (105 cases, 2 variables) using TinkerPlots; present investigations. Activity 8b: The probabilistic world: Model the population and reason with a SGD (n=105) 1 Model conjectures about the population using the Sampler, draw and compare between random samples taken from the constructed model, reason with the SGD.
