This is the highest level of research validation, corresponding to all seven 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 Likert-scale questions on the E-CLASS were developed based on consensus learning goals defined by faculty at the University of Colorado at Boulder for their lab curriculum. The questions were modeled after questions on the CLASS and based on common challenges instructors observed students having in lab courses. The E-CLASS was tested in over 40 student interviews with physics majors, non-majors and introductory physics students to ensure questions were being interpreted in the way intended. Further, over 20 experts reviewed the E-CLASS and indicated their view of the expert-like response for each question. Students in upper-division physics labs gave a larger fraction of expert-like responses than students in algebra-based physics labs in both the classroom context and in the context of professional research. The E-CLASS was given to over 5500 first year, intermediate and upper-division students (about 3500 matched pre and post) at over 45 institutions and appropriate statistical analyses of reliability and discrimination were performed. Reasonable results were found. The E-CLASS has been given to over 5500 students at over 45 institutions with results published in 6 peer-reviewed papers.
