Bronze Validation
This is the third highest level of research validation, corresponding to at least 3 of the validation categories below.

Research Validation Summary

Based on Research Into:

  • Student thinking

Studied Using:

  • Student interviews
  • Expert review
  • Appropriate statistical analysis

Research Conducted:

  • At multiple institutions
  • By multiple research groups
  • Peer-reviewed publication

The multiple-choice questions on the Density Survey were developed based on a survey of the literature and one-on-one interviews with seven high school students. The DS questions underwent expert review by three university faculty and six precollege science teachers. The DS has been given to over 750 middle school, high school, and college students and the results are published in one peer-reviewed paper.
