Abstract
The characteristic of field‐independent subjects to function consistently in a field‐independent fashion (i.e. fixity) and of others to vary more according to circumstances (i.e. mobility) has been referred to as the Mobility‐Fixity Dimension. This dimension, based on the theories of Werner, Witkin and Pascual‐Leone suggests, that field mobile students perform better than fixed students in science courses. The main objective of this study, based on high school students (mean age = 16.5 years; SD = 1.0) in Venezuela, was to test the following predictions. (1) Mobile students would obtain a better performance than fixed students on variables such as introductory high school mathematics, physics, chemistry, biology and earth science courses; and (2) among mobile students, those classified in the middle‐high range of the Group Embedded Figures Test (GEFT) and the Figural Intersection Test (FIT), would obtain a better performance as compared to those in the lower‐middle range. Results obtained, in general, provide support for the first prediction. The differences between the performances of mobile and fixed groups were, however, significant (p < 0.05) only for the biology and earth science courses. Students in one of the high mobility groups obtained a better performance (in all courses) than not only the corresponding low mobility group but also a fixed group with high scores on both the GEFT and FIT, which provides support for the second prediction. It is concluded that problem‐solving ability in science courses may be strengthened through the mediation of the Mobility‐Fixity Dimension.
