| Abstract: | Existing instruments designed to measure mathematics attitudes were too long, dated, or assessed with only western samples. To address this issue, a shortened version of the Attitudes Toward Mathematics Inventory (short ATMI) which measures four subscales??enjoyment of mathematics, motivation to do mathematics, self-confidence in mathematics, and perceived value of mathematics??was created. Its factor structure, reliability, and validity were assessed with 1,601 participants from Singapore. Confirmatory factor analyses supported the original four-factor structure. Within this structure, however, several items were found to correlate highly with others. Their removal either improved or did not impact the properties of the instrument. As a result, these items were removed to produce the short ATMI. Furthermore, a very high correlation (r?=?.96) was found between the enjoyment and motivation subscales. Results of further analysis suggested the removal of the motivation subscale. The short ATMI exhibited strong correlations with the original scale (mean r?=?.96), good overall internal consistencies, both for the full short version (???=?.93) and for the individual subscales (mean ???=?.87), and satisfactory test?Cretest reliability over a 1-month period (mean r xx ?=?.75). The validity of the short ATMI was further demonstrated through inter-correlations between its subscales, and through correlations with mathematics anxiety and achievement test scores. Participants were able to complete the short ATMI in less than 10?min, making it a viable option when survey administration time is limited. This time would reduce further with the removal of the motivation subscale. |
