| Popis: | We report here on a comparative study of middle school students’ attitudes towards science involving three countries: England, Singapore and the U.S.A. Complete attitudinal data sets from TIMSS (Trends in International Mathematics and Science Study) 2011 were used, thus giving a very large sample size (N = 20,246), compared to other studies in the journal literature. The Rasch model was used to analyse the data, and the findings have shed some useful light on not only how the Western and Asian students responded on a comparative basis in the various scales related to attitudes but also on the validity, reliability, and unidimensionality of the attitudes instrument used in TIMSS 2011. There may be a need for TIMSS test developers to consider doing away with negatively phrased items in the attitudes instrument and phrasing these positively as the Rasch framework shows that response bias is associated with these statements. |
