The Colorado Science Education Initiative has developed a wide range of curricular materials for teaching junior-level quantum mechanics, of which the QMAT is only one. Please visit the website (http://www.colorado.edu/sei/departments/physics_3220.htm) for other materials such as group activities, clicker questions, and homework.

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 open-ended questions on the QMAT were developed based on questions from other quantum mechanics assessments, faculty input and observed student difficulties with relevant concepts. Students participated in think aloud interviews about the questions, which were subsequently revised. The QMAT questions were given to over 25 students, and further revised. More student interviews were conducted and experts reviewed the QMAT. The QMAT has been given to over 60 students at one institution and the results published in one peer-reviewed publication.
