Fifty education majors in two sections responded to an Attitudes toward Mathematics and Its Teaching (ATMAT) scale. Results with two psychometric models, classical true-score theory and the one-parameter Rasch model, supported the ATMAT's reliability, content and construct validity, and invariance over three time points.

Data from 196 Irish school children were analyzed and used to develop a shortened version of the Fennema-Sherman Mathematics Attitudes Scales (E. Fennema and J. Sherman, 1976). Internal consistency estimates of the reliability of scores on the whole scale and each of the subscales of the original and short form were favorable. (SLD)

Used a multitrait-multimethod approach to investigate the validity of scores on locally prepared performance assessments taken by 6,000 third and fourth graders in reading, language arts, and mathematics. A partial explanation for the lack of construct validity evidence for the performance assessment scores is the probable low reliability of…
