Research-based Validation
This is the lowest level of research validation, corresponding to at least one 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 QMCI were developed based on student difficulties with potential barriers, tunneling and probability distribution in one-dimension. The questions were tested with student interviews. The QMCI has been tested with 8 students and results are published in one paper.

Typical Results

There are no typical scores available. 

The latest version of the QMCI, released in 2004, is version 1.03. All research has been done on Version 1.02. The only difference between 1.02 and 1.03 is that the word "higher" has been changed to "greater" when describing wavelength in question 9.
