Crowdsourcing: Topic Checklist (Computer Science Principles 5.4)

Specific I can statements for crowdsourcing, each linked to the guide section and practice question that tests it.

Work through the list without notes. If you cannot do a statement, follow its link, then come back. Guide = study guide; Practice = practice questions.

Understanding

  • I can define crowdsourcing and citizen science and give an example of each. (Guide: “Many people, one task” and “Citizen science”; Practice Q1, Q2)
  • I can explain how public data and wide access to information help people solve problems at scale. (Guide: “Information, public data and problem-solving at scale”; Practice Q6)
  • I can explain how crowdsourcing offers new models of collaboration and funding. (Guide: “Information, public data and problem-solving at scale”; Practice Q3)
  • I can list challenges: quality, uneven participation, privacy and fair credit. (Guide: “Challenges and limits”; Practice Q5, question 10)

Skills

  • I can apply a threshold rule to counts of reports and list what is confirmed. (Guide: Worked example 1; Practice Q4)
  • I can calculate the share of contributions from each group or area. (Guide: Worked example 2; Practice Q8)
  • I can compare shares of contributions with shares of the population or area. (Guide: Worked example 2; Practice Q8)

Reasoning

  • I can evaluate a crowdsourced data set for quality and coverage. (Guide: Worked example 2; Practice Q7, question 10)
  • I can suggest ways to improve reliability and representation. (Guide: Worked examples 1 and 2; Practice Q9, question 10)
  • I can link uneven participation to the digital divide and bias. (Guide: “Challenges and limits”; Practice question 10)
