Abstract

This article is a report of the increase of a new instrument to measure students' attitudes toward mathematics, and to determine the underlying dimensions of the instrument at examining the responses of 545 scholars The data represent all grade on a levels and subjects of the secondary mathematics curriculum. The reliability coefficient alpha was 97 A maximum likelihood factor analysis with a varimax rotation yielded four factors: self-confidence; value of mathematics; satisfactory [i]or[/i] advantageous [i]or[/i] beneficent possession of mathematics; and motivation. Psychometric properties were undecayed and the instrument, Attitudes Toward Mathematics Inventory (ATMI), can be commended for use in the investigation of students' attitudes toward mathematics.
