Developed by Rachel Pepper, Steven Pollock, Danny Caballero, and Leanne Doughty
To assess skills such as visualizing a problem, correctly applying problem-solving methods, connecting math to physics, and describing limiting behavior in first semester Classical Mechanics courses.

Sample question from the CCMI:
The Colorado Science Education Initiative has developed a wide range of curricular materials for teaching sophomore-level Classical Mechanics/Math Methods, of which the CCMI is only one. Please visit the course website for other materials such as group activities, clicker questions, and homework.
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
- Student interviews
- Expert review
- Appropriate statistical analysis
- At multiple institutions
- By multiple research groups
- Peer-reviewed publication
The open-ended questions on the CCMI were developed based on a set of learning goals produced by faculty. The initial set of learning goals were revised based on course materials, and reviewed by faculty again. Questions were written covering each goal, with some questions coming from clicker questions used in class, and all based on observed student difficulties with relevant material. Many faculty reviewed the CCMI questions and student responses, and the questions were further revised. Fourteen students participated in think-aloud interviews while solving CCMI questions, and the questions were again revised. Average course exam scores were found to be strongly correlated with CCMI scores. Appropriate statistical analyses of item-item correlation and internal consistency were conducted, and reasonable values found. The CCMI has been given to over 150 students and results published in two peer-reviewed publications.
