An Evidence-Based Digital Investigation

In this project course, a student team investigates why Cedar Valley High's Wi-Fi slows to a crawl at lunch. Learners turn a complaint into a testable question with competing hypotheses, choose data sources (access-point logs, latency measurements, link usage, a survey, a schedule) with permission and privacy safeguards, analyze fair comparisons across time, place and days, write claim–evidence–reasoning statements that match the strength of the evidence, name confounders and limitations, and write a full investigation report with evidence-based recommendations.

  • 4 lessons
  • About 120 minutes
  • Check what you learned: 10 questions
  • Ways to answer: fill in the blanks, choose an answer, trace code, highlight a text, match pairs and type a number

What learners will discover

  • Turn a vague complaint into a focused, testable investigative question with competing hypotheses and predictions, and choose data sources that can test them while respecting permission and privacy.
  • Analyze log and measurement data by making fair comparisons across time, place and conditions, including a natural experiment, to see which hypotheses the data support.
  • Write claim–evidence–reasoning statements whose strength matches the evidence, and identify confounders and limitations with ways to address them.
  • Communicate an investigation in a structured report whose recommendations follow from the evidence and include a way to check that they worked.
