Research Validation Summary
Based on Research Into:
- Student thinking
- Student interviews
- Expert review
- Appropriate statistical analysis
- At multiple institutions
- By multiple research groups
- Peer-reviewed publication
The multiple-choice questions on the QMVI were developed based on the results of a survey of topics common to modern physics and junior-senior level quantum mechanics courses and comparison of these topics to those in commonly used textbooks. The topics were reviewed by experts and then questions were written for each topic. The initial version of the QMVI was given to over 60 students and appropriate statistical analyses of difficulty, reliability and discrimination were conducted. The questions were revised and given to a new group of over 40 students. The questions were then reviewed by experts and again revised. Statistical analyses of reliability and difficulty were conducted again, and the test was found to be reliable and slightly difficult. The QMVI has been given to over 200 students and results are published in one peer-reviewed article and one dissertation.

Percent correct +/- standard deviation on version 0.4 of the QMVI for five different courses at one university, and the number of respondents in each class out of the total enrollment (resp/total) from Robinett and Cataloglu 2002.
The latest version of the QMVI, released in 2000, is version 0.4. Earlier versions were revised based on feedback from physics faculty and analysis of students' written responses.
