RESEARCH VALIDATION
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 TUV were developed based on student thinking about vectors collected using open-ended questions. Students’ responses to these questions were used to create the answer choices. This initial set of questions was reviewed by experts, tested with students and revised. Statistical analyses of reliability, difficulty and discrimination were conducted and reasonable values found. The TUV has been given to over 400 students at one institutions and results published in 2 peer-reviewed papers.
