Abstract
In this paper, I reported the development, the validation and the application of the Shimane Affective characteristics Test toward School Mathematics (Shimane-ACTM) developed by the author's investigations on the affective domain in mathematics learning for 16 years. Main evidences that suggest the following have been presented: (1) The ACTM obtained a high discrimination validity by the item analysis. (2) Cronbach's a coefficient was 0.832, and the ACTM obtained a moderately high reliability. (3) A principal conmponents solution using the principal axis method with Varimax rotation resulted four factors: Self concept toward mathematics, Achievement motivation in mathematics learning, Mathematics anxiety, and Attitudes toward mathematics. (4) The cluster analysis resulted four clusters as well as the results of the factor analysis. It was concluded that the ACTM could be used for evaluating the affective charactreistics toward school mathematics.
