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 STPFaSL-short were developed by consulting with instructors of introductory courses about topics and content goals, as well as materials for these courses, and completing literature review of student difficulties with relevant topics. A preliminary distribution of questions from various topics was developed in consultation with instructors. Free-response versions of the questions were then given to students, and the responses used to create the multiple-choice answers. Students interviews were conducted and expert input incorporated at various points in the development process. Appropriate statistical analyses of difficulty, discrimination and reliability were conducted and reasonable results found, with the exception of low reliability on pre-test scores for introductory students. The developers also tested the effect of changing the order of the answer choices and found no differences between versions. The STPFaSL-short has been tested with over 2000 students enrolled in introductory and upper level undergraduate thermodynamic courses and 45 entering physics graduate students in their first semester of the graduate program. The results are published in one dissertation.

Typical results on the STPFaSL-short from (Brown 2015). See the section on question clusters for information on which questions are included in each sub-category.
The latest version of the STPFaSL-short, released in 2015, is version 1. The STPFaL-long was released in 2022 and contains the same 19 question contexts as the STPFaSL-short, but the STPFASL-long splits most questions into several sub-questions where each asks about only one thing, e.g., one thermodynamic variable.
