Comments:

The tool is designed to provide a profile of how people evaluate science vis-a-vis other important aspects of culture. While the subjects of the original studies were preservice elementary teachers, the tool could be used with anyone whose reading level equals the readability of the instrument.

This study made use of TSSI, reliability and validity were assessed in context to the other assessment measure used, EBI (Epistemic Belief Inventory). The study makes reference to many other current studies having used the assessment (TSSI) which suggests it acceptability and accuracy. Rasch modeling was used, it compared the degree of fit between observed students response data and predicted values by the model, therefore only scales that show acceptable model fit and reliability are retained. Rasch showed the two scales to not be unidimensional and did cluster around functional dimensions as expected. All three subscale of TSSI had acceptable item functionality and so were retained. The scale reliabilities showed improvement could be possible however were generally acceptable (range from 0.64 to 0.99).
