Abstract:
The purposes of this research were to compare the reliability andthe construct validity of computer subject attitude test with differentproportions of favorable and unfavorable statement which devised intosix forms ; The first form was 100 % : 0 %, The second form was80% 20%, The third form was 60 % : 40 %, The fourth form was40% : 60%, The fifth form was 20% 80% and The sixth form was0% 100%.The samples used in this research were 659 Mathayomsuksa 2 public secondary school students in Nakhonratchasima Province in the second semester of 2000 academic year. The Attitude test with Likert scale towards computer subject was used for data collection.The data were analyzed by computing the internal consistency reliabilitycoefficient and used chi-square test for comparing the coefficients.Meanwhile, comparing the construct validity by number of factors formFactor analysis.The results of this research indicated that1. In comparing the reliability coefficient, It found that the statistical difference in six pairs, namely, the first form and the sixth form, The second form and the sixth form, the third form and the fifth form, The third form and the sixth form, The fourth form and the sixth form.2. In comparing construct validity, It found that only in the sixth form had the correct number of factor.
