Comments:

The tool has three versions of the instrument: A, B, and C; each version has 8 common questions and a total of 59 questions.

Other Reference:
Smith, H. J. (2014). What do students find relevant in an introductory Geology course? Implications for changing students attitudes about the relevance of Geoscience in society. GSA Annual Meeting in Vancouver, British Columbia, 265.
CARS was used to quantitatively analyze changes in student attitude, finding no significant difference. This suggests the instrument is still in use for papers and subsequently still valid.
