Teachers' implicit beliefs about (mathematical) intelligence
Abstract
Implicit theories of intelligence are individual beliefs about the nature of intelligence, which are used on a daily basis as part of self-assessment and assessment of others, and are a significant factor shaping attitudes and behaviors. Research to date suggests that teachers can influence their students' beliefs about intelligence, which in turn affect motivation and achievement. According to Dweck's model, implicit theories of intelligence are a bipolar construct, with two theories at its extremes - the entity theory, which stresses the immutability of intelligence, and the incremental theory, which holds that intelligence can be improved through training and learning. Recent research, however, indicates that these two theories represent distinct, uncorrelated dimensions. The aim of this study was to carry out a psychometric evaluation of the Implicit Theories of Intelligence Scale (ITIS) and the Mathematics-Oriented Implicit Theory of Intelligence Scale (MOITIS). 228 primary and secondary school teachers in Serbia (87.7% female; average age 42.79 years) took part in the study. The results of factor analysis suggest the existence of two factors on both scales: incremental theory and entity theory. Further analysis showed that both factors of the ITIS and MOITIS scales have satisfactory psychometric properties. Significant differences were detected between primary and secondary school teachers on the ITIS scale. More specifically, among teachers of science subjects, mathematics and medical subjects the attitude that intelligence is a fixed trait is more pronounced than among teachers of the arts, humanities and social sciences.
