Empirical validation of the conceptual structure of a test of Science-Related attitudes
*Subscription may be required
The 70 items of the Test of Science Related Attitudes (TOSRA) were given to 1041 students who responded directly to them as attitude test items and to 39 teachers who were asked to assign the items to categories, without directions about either the number of categories to be used or the criteria to be employed in establishing them. Factor analysis of the item correlation matrix obtained from the student responses suggested that the seven subscales of the test were not distinct. Factor analysis of a joint proportions matrix for the items, obtained from the teachers' categorizations of the items, suggested that there are clear conceptual distinctions among the seven subscales even if not operational distinctions.
