Abstract
The purpose of the study were, (1) to develope a SD type attitudinal instrument, picking up some of the items belonging to the evaluative dimension from the items of the instrument MSD measuring attitudes toward school mathematics, and (2) to obtain the coefficients of correlation among the scores on the developed instrument, the MSD and the MSD-E. Under the factorial validity, we developed an instrument named MSD-A with four items depending on the data obtained from 281 sixth grade students. There were high correlations among the MSD-A, the MSD and the MSD-E.
