Instructional Ideas
  • Create additional practice problems relating reliability, accuracy, and precision to experimental results
  • Bring in a magnetic or foam dart board and have class members determine their own personal reliability, accuracy, and precision
Classroom Considerations
  • Prior knowledge of finding a mean would be helpful, but is not required
Pros
  • Utilizes many graphs and graphics to support visual learners
  • Video focuses on only these concepts, preventing scholars from becoming overwhelmed
Cons
  • None
