Sample questions from the TCS:
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 multiple-choice questions on the TCS were developed using results from previous studies on students’ understanding of thermodynamics topics and then these questions were translated into Thai and the translation was verifies by experts. The content of test questions were reviewed by experts and the test was given to graduate students to make sure the questions were easy to understand. The test was revised and given to Thai students in introductory physics courses as well as those in an upper-division thermodynamics course. The test was then divided into two parts and appropriate parts were given to introductory and upper-division students in Australia. Appropriate statistical analyses of reliability, difficulty and discrimination were conducted and reasonable values found for each. The TCS has been used with over 2000 students at two institutions. There is one peer-reviewed publication presenting TCS data.

Typical results for TCS from Wattanakasiwich et. al 2013.
Fund = Australian 1st yr. undergrads who did not studied physics in high school. Reg-1 = Australian 1st yr. undergrads who mostly studied physics in high school. 1st Adv = Australian 1st yr. honors undergrads who studied physics in high school. Reg-2 = Australian 1st yr. undergrads who are taking the first–year reg. physics course. 2nd Adv = Australian 2nd yr. university physics students. Phys-1,2,3, and 4 = Thai 1st yr. undergrads. majoring in science who studied physics in high school. 2nd Phys = Thai 2nd yr. undergrads. physics majors in second-year thermodynamics class.
The latest version of the TCS, released in 2011, is version 2. Version 2 consists of two parts: Part I covers temperature and heat transfer, and ideal gas law. Part II covers the first law of thermodynamics and processes. In version 1, these two parts were mixed together. They were separated, according to the authors, "to make the survey match with Australian high school curriculum."
