Silver Validation
This is the second highest level of research validation, corresponding to at least 5 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 questions on the PLIC came from an experiment conducted in an introductory physics lab, initially based on the series of questions an expert posed to themselves when conducting the experiment. These were then refined several times through think-aloud interviews with introductory and upper-division physics students (majors and non-majors), as well as through open-response question responses. The PLIC is still under development.
